"Modus Operandi in Opus Operatum.
The shaping of historical wooden towns by traditional workmanship."

The aim of this thesis was to analyse the phenomenon of traditional workmanship and its role in urban conservation throughout history and in recent times by focusing on the main case of Røros in Norway, and by comparing it with two supplementary cases of urban conservation: Kokkola in Finland and Trakai in Lithuania. Besides the multinational case studies, the research also took a multidisciplinary (socio-historical, architectural and socio-anthropological) approach in order to show how the concept of “traditional workmanship” was used as the legitimizing instrument in the practice of heritage conservation and how this concept evolved over time, by including differing or even contrary content that, in turn, resulted in varying architectural and urban physical expressions after practical actions of heritage conservation were taken.

This research sought to improve the body of knowledge about urban conservation in practice, by tracing and describing active processes of conservation projects. Hereby, the use of traditional workmanship was analysed through the levels of urban, architectural conservation, and by highlighting the detailed woodworking. One actual ongoing conservation project was investigated in each of the chosen urban conservation areas by using qualitative research methods, while the quantitative analysis mapped diverse social structures within three historical wooden towns. The comparative study of urban conservation performances was conducted by applying and verifying Pierre Bourdieu’s theoretical framework.

Finally, a hypothesis was tested that national fields of heritage conservation developed demand for traditional workmanship by creating supply, i.e. by establishing the subfields of traditional workmanship. The highlighted varying statuses of subfields of traditional workmanship in different space and time dimensions enabled the disclosure of the level of dependency of the subfield of restricted cultural production on the field of heritage conservation and vice versa, and therewith allowed the assessment of the actual role of traditional workmanship in urban conservation of wooden historical towns.

"A QUEST FOR CONTINUITY FOR PEACE AND PROSPERITY: Post-war land and property claims and disputes in northern Uganda - The case of the Acholi group in Amuru sub-county" 

Land is one of the few valuable resources in post-conflict rural communities which support return, reconstruction and early recovery. As such, reinstating land claims to returnees makes a significant contribution to the renewal and sustenance of their livelihoods. This research focuses on Amuru sub-county, Northern Uganda as a case to examine how perceptions and attitudes emerging from the Acholi’s prolonged displacement in camps affected their return and recovery. It addresses the impacts these perceptions have had on land and property claims and associated disputes.
The research adopts a grounded theoretical approach to data collection and a matrix as an analytical tool. Pragmatic symbolic interactionism is used in understanding and interpreting actors’ perceived truth and actions. The analysis accepts that displaced individuals’ perceptions emanating from forced dislocation and dispossession are real in relation to influencing land claims and associated disputes. Furthermore, this research uses existing theories and discourses that can offer a basis for studying forced displacement that is associated with land claims related to: 1) ancient concepts of territory, land and property relating to current trends and practice; and 2) development and reconstruction discourses.
To conduct this research, qualitative interviews and observation, focus group discussion, documentary evidence and archives, textbooks and journal articles were utilised. The collected information formed a matrix for data analysis and case presentation.
The research findings show that perceptions and attitudes developed during displacement affected the process of land claims and associated disputes. These issues include: threats to women’s rights to land, monetisation of the local economy, changes in traditional values and practices, emergence of land markets, and participation and consultation. While it is vital for government and international donors to facilitate the restitution of land and property to returnees, the restitution alone is insufficient without strengthening land tenure security. This research shows that the formalisation of land tenure is key to providing security of ownership and investment, though it remains controversial and costly to implement. The research argues that simple forms of rights formalisation are necessary in order to either retain customary rights through a legal approach or transfer rights to land into a modern freehold system.

"The influence on urban transport infrastructure on bicycle route and mode choice"

The prioritisation of bicycle-friendly infrastructure is now on the agenda of many policymakers seeking to capitalise on the advantages of cycling for transport. This thesis focusses upon how the improved availability, quality, and connectivity of infrastructure suitable for cycling can influence cycling behaviour at the city and neighbourhood level.

Two key elements are necessary to understand the local-scale impact of bicycle infrastructure: the decision to bicycle in preference of other transport modes and the choice of route on the transport network. This thesis first addresses bicycle mode and route choice independently of each other before analysing the interaction between these elements in the context of bicycle infrastructure interventions.

This article-based thesis is comprised of five separate research papers: four empirical studies and a literature review. Three of the empirical cases are based in the Norwegian city of Trondheim and the fourth is based in Oslo. Paper I concerns the modal shift of employees following a workplace relocation. Papers II and III are focused on bicycle route choice – firstly as a review of methods and then in connection with student route preferences. The two final papers, Papers IV and V integrate both mode and route choice elements for the detailed analysis of neighbourhood scale effects resulting from the installation of bicycle lanes in Trondheim and Oslo respectively.

The research uses a mixed methods approach, with a focus on empirical data to address the objectives of the thesis. Before and after travel surveys, web-based maps and GPS are the main means of data collection. Comparative analyses are performed using a Geographic Information System (GIS).

Findings suggest that the decision to bicycle is to a significant extent determined by trip and spatial characteristics of the destination (Paper I). Route substitution is witnessed in both intervention studies (Papers IV and V), whilst significant changes (p < .05) in the modal share of cyclists is only witnessed in one (Paper IV), suggesting that it is mostly changes of route rather than mode that contribute to an individual intervention street’s change in bicycle volumes.

Bicycle-specific infrastructure appears to be generally valued by all types of road users, however, the evidence suggests that public transport users and pedestrians are more willing to change their mode of transport assuming the only changes made are to the bicycle infrastructure (Papers I and IV). This suggests that much of the increase in the use of new bicycle infrastructure is the result of a reduction in the use of other sustainable transport modes. Many of the benefits associated with increased cycling are the result of reduced private car use, but for this to be achieved, it appears that initiatives beneficial for cyclists alone are insufficient.

The means by which different transport infrastructure attributes can be researched and are valued by users are discussed by Papers II and III respectively. Paper II is a systematic review summarising the means through which revealed preference bicycle route choice data can be collected whilst Paper III evaluates four different Bicycle Level of Service (BLOS) methods for determining bicycle route choice. The latter study reveals that empirically founded BLOS methods with the most explanatory infrastructural attributes correspond best with actual route choices of university students, with the Bicycle Compatibility Index having the best match.

Developing an understanding of the impacts of bicycle infrastructure can assist the prioritisation of limited city budgets towards the promotion of sustainable mobility behaviour. This research attempts to advance the state of the art for bicycle route choice research whilst also addressing the decision to bicycle for transportation purposes.

Debates on Open Form and Marxist-Leninism in Norway around 1970

Veiledere: Branko Mitrović og Thordis Arrhenius

The thesis begins with the observation of a radical, political impulse appearing in the architectural debate in Norway in 1970, expressed by the movements of Open Form and Marxist-Leninist architects. Compared to the preceding modernist critique of the 1960s, this radical-political shift was stronger in its rhetoric, more dismissive of its opponents, and more radical in its political argumentation.

The thesis studies how this shift manifested in fierce debate in Norwegian architecture magazines and how it addressed, and was in turn fueled by, a changing professional reality, where the role of the postwar architect-specialist was threatened from several sides. The intersection of architecture and society became the crux of a new form of systemic critique that explored how architecture was organized both as intellectual and productive work in society.

”Kulturminner og analyse. Vurdering av vernede bygninger innenfor kulturminnevern, arkitektur og offentlig investeringsanalyse”

Analyse av vernede bygninger utføres innenfor flere fag, slik som kulturminnevern, arkitektur og offentlig investeringsanalyse, og på vesensforskjellig vis. De fagfeltene som er involvert i vernede bygninger og ideelt sett skal samarbeide, har vidt forskjellige perspektiver og varierende grad av bevissthet rundt vernede bygninger og verdiene disse besitter.

Avhandlingens mest kritiske funn er empiriske data som viser at offentlig investeringsanalyse i dag har manglende diskusjon av både nytte og kostnad forbundet med vernede bygninger. Slik analyse har manglende diskusjon av vernede bygningers verdi og potensiale for bruk, og av følgekostnader for fraflyttede vernede bygninger ved diskusjon av nybyggalternativ. Manglende diskusjon av kulturminneverdier og kostnadene forbundet med dem er viktige funn, fordi offentlig investeringsanalyse veileder politikeres beslutninger ved valg av konsept. Avhandlingens konklusjon er at offentlig investeringsanalyse vedrørende vernede bygninger vil kunne tjene på å vektlegge kulturminner og inkludere andre fagperspektiver i analysen av vernede bygninger, fordi det kan gi et mer komplett bilde for beslutningstager. Samtidig kan arkitektur og kulturminnevern få større politisk gjennomslag gjennom å engasjere seg i offentlig investeringsanalyse i større grad.

”Green Leasing: A study of the Barriers and Drivers for Green Leased Offices in Norway”

Avhandlingen diskuterer grønn utleie i kontorbygg, driverne og barrierer knyttet til utvikling og implementering, med et spesielt forskningsfokus på Norge

Abstract | PhD | David Collins

This thesis discusses Green Leasing in office buildings, and the drivers and barriers associated with its development and implementation, with a particular research focus on Norway.
The research for this project was funded by NTNU, more specifically the Centre for Real Estate and Facilities Management at the Department of Architecture and Planning in the Faculty of Architecture and Design.

The aim of this thesis was to explore Green Leasing and related topics (such as Green Leases) in the context of their potential (both currently and prospectively) in the context of the built environment.
This project is a three-phase study using mixed methods and is for the most part exploratory, containing a combination of interviews, a survey and literature research.
The end objective was to better understand the state of current research and terminological penetration, the drivers and barriers for the development of Green Leasing in offices, as well as the current situation and future possibilities for facilities management in this context.

The results of these studies are presented in the thesis as well as the attachment of eight articles, seven of which have undergone full peer review and acceptance for publication in their respective journal or conference at the time of this thesis publication.

Det høyaktuelle temaet campusplanlegging for NTNU på Gløshaugen har vært Savis Goharis bakteppe for doktorgradsavhandlingen:

"Governance in the planning and decition-making process. The co-location case of university campuses in Trondheim, Norway (2000-2013)".

Savis Gohari forsvarte sin doktoravhandling 5. april 2019, ved institutt for teknologi NTNU,Trondheim.

The co-location of NTNU campuses in Trondheim has involved many different and contrasting political interests and power relations that has undermined the process of decision-making and planning for more than 20 years. The essence of this thesis was distilled from the general assumption that network governance, which is based on the negotiation and collaboration rationality, can overcome the limitations of anarchic market exchange and top-down planning and decision-making.

The main research question has been ‘how the governance structure and process have influenced campus development in Trondheim from 2000 to 2013’. The thesis tried to empirically address the complex, non-linear and multi-layered processes of NTNU’s co-location case, using and integrating different theoretical-analytical models, including ‘structural-functionalism’ and ‘rounds model of decision-making’ to explain and illuminate why the co-location was stopped in 2006 and thereafter approved in 2013. The thesis represents an embedded single case study, which looked at three levels of governance: understructure and superstructure, referring to ‘university governance’, and middle structure or ‘urban governance’. Accordingly, the research objective was to analyze ‘governance structures’, i.e. the way actors stand in a network and interact with each other across levels, together with ‘governance processes’, i.e. the interrelation between actors’ attributes (such as interests, resource, power and roles) at different levels and rounds of decision-making.

The thesis conclude that in order to understand complex, unpredictable and non-linear planning and decision-making processes, one should go beyond legal and formal frameworks, investigating the political structure underpinning the informal functioning of governance in terms of different actors’ roles, interests, resources and power. Thus, exploring governance requires political, cultural and periodic review. A longitudinal perspective can help to unfold the chain of events and processes, which can provide a better understanding about the reality of the case. In order to evaluate the effectiveness of a governance model, the thesis recommended identifying governance structure, operational efficiencies and ways of remedying its deficiencies in interaction with governance functions and processes.

”Use of project execution models and BIM in oil and gas projects: Searching for relevant improvements for construction”.

Olje- og gassindustrien er preget av store og komplekse prosjekter og har investert tungt i utviklingen av ny teknologi. Prosjektutførelsesmodeller (PEM) er innført som en strukturert måte å gjennomføre tverrfaglige arbeidsprosesser gjennom alle prosjektfaser. Byggemodellmodellering (BIM) benyttes i samordning av komplekse prosjekter og er en del av arbeidsprosessene som er definert i en PEM. Dette har vært grunnlaget for det første spørsmålet: Hvordan brukes PEM og BIM i store olje- og gassprosjekter i de tilfeller som er studert? Utviklingen mot større og mer komplekse prosjekter i byggebransjen betyr at aktører i byggebransjen vil dra nytte av å skaffe seg kunnskap og læring fra olje- og gassindustrien. Dette har vært grunnlaget for det andre spørsmålet: Hvordan kan erfaringer fra de studerte sakene være relevante for forbedringer i byggeprosjekter?

“A Multi-Perspective Observation of Site Museums. Case study of Archaeological Site Museums in China, with Norwegian Example as Reference”

Based on the documentation and analysis of anthropological fieldwork carried out from 2009 to 2015 on three selected site museum cases, this dissertation focuses on the phenomenon of installation management in Chinese site museums placed in the context of high-paced social transformation and modernization, with a Norwegian example as reference. It begins with a brief history of the formation of Chinese and Norwegian conservation institutions. Thereafter, it proposes and tests a social communication pattern of site museum management in China, explored via the origin and definition of ‘site museum,’ by revisiting some related essential conservation principles. Finally, it provides an assessment framework composed of the authenticity, integrity, and continuity concepts which build upon the fundamental issues of site museums. 

The Daming Palace National Heritage Park and Han Yangling Museum in Xi’an, specifically the archaeological exhibition hall for the Outer Burial Pits of Yangling Imperial Cemetery of Han Dynasty, are taken as the study cases in China for the field investigation and further exploration. Meanwhile, the Hedmark Museum, an archaeological site museum in Norway, acts as the reference example for the fieldwork and research. Methodologically, this involves a multi-perspective approach which combines historical, anthropological, archaeological, and architectural studies on site museums. The methods of social anthropology are employed as the scientific tools in the fieldwork through semi-structured interviews and participant observation. Particularly, the interview documentation concentrates on the reflection of the different participants including museum staff, archaeologists, architects, civil engineers, contractors, and conservation officers who represent different institutions participating in the related site museum projects. A critical analysis of the cases helps clarify the basic principles of site museum construction and may also be useful for similar practices in other countries. Together, the collected interview notes provide valuable insights into the role of archaeological site museums in the operation of cultural heritage management and enhancement. Sixteen informants from different professional fields were interviewed. These interviews provide valuable documentation as oral history records that can draw an overall picture of the Chinese and Norwegian cases. Particularly, many of the interviewees, as professionals in different relevant fields of museums and architectural conservation, express their different thoughts and ideas on the practice of architectural conservation in China and Norway, meriting this study as a baseline for future research.

“From outsideness to insideness - placemaking in public space”

This thesis originates from observations made in practice, giving rise to a curiosity about the conditions that encourage, or discourage, people to interact with public environments. It investigates the concept of placemaking with the aim of defining what placemaking means to architects and urban designers in theory and practice. It points at possibilities and consequences of the approach, and for whom. Placemaking is the simultaneous building of physical objects and relationships; relationships between people, and relationships between people and places. The theoretical core of the thesis strives to enrich the view on the built environment by adding the perspective of lifeworlds to the urban planning discourse. Five key concepts are used to describe this transformation process: place attachment, place outsideness, place insideness, involvement, and cocreation. 

Putting place attachment and co-creation on the conscious, professional agenda of architects and urban planners is the main message from this research. Furthermore, clarifying the possible effects of placemaking on individual well-being as well as on the physical qualities of a place is central in this work. In order to work with placemaking, professional actors (including municipalities) have to become clear about in which of Carmona’s phases they are willing to let others contribute, and then find the appropriate working methods for this to happen.

”Integrated Workplace Concepts and Organisational Change”

Veiledere: Geir K. Hansen (prof.) og Siri H. Blakstad (prof.) ved NTNU.

This doctoral thesis investigates the use of Integrated Workplace Concepts (IWCs) as a strategic tool to affect organisational change and development. Previous research has illustrated how spatial environments with great effectiveness may be used to influence and change a wide variety of organisational aspects. Inconsistent and conflicting findings, however, raise the need for creating a deeper understanding of the effects of such spatial change initiatives. The focus in this research is therefore built on a constructivist and more precisely a sociomaterial perspective. Special attention is therefore given to how IWCs are strategically used by the organisation and further understood or ‘translated’ as the new concept is implemented.

Through a literature review and three case studies, it has been investigated how these strategic efforts unfold in different organisational contexts.

The main focus is placed on whether the concept function as intended – succeed in achieving the intended ends – or whether unintended outcomes have challenged the strategic change efforts. Special attention is given to studying how underlying issues such as; conflicts of interests, work patterns, cultural and departmental differences, organisational hierarchies and the like are influential in the execution of spatial change management strategies.

"Urban Densification and the Sustainable City in Norway: A Study of Drivers and Barriers"

This article-based doctoral thesis addresses the following question: What are the main drivers and barriers of urban densification as planning strategy in the quest for more sustainable cities in Norway?

The research uses a mixed-method approach to explore specific aspects of the densification process. One such aspect is the practicability of making denser the sprawling Norwegian cities, and the effects that such gains in density imply for transport, one of the most significant aspects of sustainability. Another aspect investigated is the issue of social acceptability using land prices as a proxy. The analysis, based on a hedonic pricing model for Trondheim, indicates a tendency towards higher prices of dwellings per square metre in denser locations, although some aspects of density seem to produce a contrary effect. The research also delivers a systemic overview of the actors and factors shaping urban development. This analysis applies a multilevel-perspective approach used in sustainability transition studies to study the main factors and actors behind urban densification in Trondheim. Resulting data indicate that despite a strong emphasis in planning towards sustainability, practices behind urban development have not changed much. 

As an answer to the main question posed above, the main drivers and barriers of urban densification in Norway are as follows. The environmental: Global environmental concerns have driven the adoption of national and local policies towards greater efficiency in the use of natural resources and a decrease in pollution. Urban densification is regarded as an important means to achieve these targets. The most important environmental barrier is the pre-existence of a scattered urban layout, fragmented in the rugged Norwegian geography, which makes it difficult to increase urban density and make substantial gains from recent changes in policy. The social: Demographic changes have facilitated the application of densification policies but entrenched social values, such as freedom of choice, make it difficult to apply restrictive measures, such as urban containment or car-usage restrictions. The economic: Changes towards a knowledge-based economy imply multiple benefits from larger, more intense urban environments; but given the pre-existence of a large sprawled urban form, the sunk investments in infrastructure make it difficult to accelerate urban changes towards denser urban environments. The institutional: The discourse on sustainability has gained strength at almost all institutional levels. However, to a large extent legal frameworks and procedural traditions remain unchanged.

"Impact of faults and Fractures in Geomechanics of Reservoir Pressurization:
A numerical Approach"

The importance of geomechanical modeling has risen due to the increase in the concerns about the possible seismic activities and leakage problems due to the reactivation of faults/fracture in the reservoir-caprock system during fluid injection, especially in very large scale CO2 sequestration projects. Global warming and its consequences from one side and the geomechanical risks associated with CO2 storage from the other side have forced the geomechanics research community to study every possible source of these risks and the associated advanced methods of investigation. Throughout this thesis work, it was attempted to investigate the geomechanics of fluid injection problem from several prospective using Modified Discrete Element Method (MDEM). Stress path evolution and the likelihood of fault/joint reactivation during reservoir pressurization were investigated. Stress path is perturbed in the presence of faults due to the elastic shear deformation of faults. This perturbation can destabilize some parts of the system in the reservoir-caprock interface region. Effect of parameters such as fault shear stiffness, Poisson’s ratio, and reservoir aspect ratio were studied on the quantity of the stress path perturbation. Stress path hysteresis was also investigated in the thesis. A reduction in the stress path was observed due to damages occurred during reservoir depletion in the reservoir flanks. The stress path hysteresis implies a less stable fluid injection into depleted oil and gas reservoirs. New developments in MDEM were presented in the thesis. A Linear Elastic Fracture Mechanics (LEFM) based methodology was developed. By this methodology, MDEM can calculate stress intensity factors, KI and KII using the contact forces of particles. It is able to be used in complex boundary condition and geometrical configuration such as curved and interacting multiple cracks with acceptable accuracy. The methodology has been also used in reservoir scale to study the rupture likelihood of faults and fracture. Mode I and II Stress Intensity Path (SIP) coefficients were introduced in the thesis as the change of stress intensity factor per change of reservoir pore pressure. SIPs can be used to investigate the likelihood of faults rupture growth in the reservoir-caprock system. Using SIPs for a given fault, some relationships were proposed to find the critical overpressure to prevent propagation of reactivated fault/fractures in mode I and II. The elastic-softening Crack Band mesh size independent model was also embedded into MDEM. The code is now able to model nonlinear behavior of quasi-brittle materials including and excluding preexisting cracks based on fracture energy.

”The Facility Management and Building User Interaction in the delivery of Energy Management Services:
Theoretical approach and practical applications for facilities managers on non-residential buildings”

The built environment is accredited for a significant portion of global energy consumption (40%) and generation of Green House Gas (GHG) emissions (36%). Reducing the amount of energy used during the service life of buildings is paramount towards reducing the sector´s energy and carbon footprint. Strategies that include the adoption of passive design building concepts and the introduction of energy efficient technologies are essential to supporting energy efficiency goals. 

However, mounting evidence indicates that buildings designed for low energy use can often perform much worse than their design intentions, an issue commonly referred to as the energy performance gap (EPG). How people choose to use or interact with buildings is widely regarded as one of the most significant factors influencing this performance gap. Energy strategies that aim to reduce energy use by modifying the energy-behaviour of building occupants are increasingly gaining attention. Facility managers can play a strategic role in leading organizational change towards building a sustainable workforce

Vegard Knotten har med suksess forsvart sin doktorgradsavhandling, 6. februar 2018:

«Building design management in the early stages».

Målet med oppgaven har vært å si noe om hvordan prosjekteringsledelse i tidligfase av byggeprosjekter bør håndteres. BAE-næringen står overfor mange endringer, og de tidlige fasene av byggeprosjekter regnes som de mest krevende og utfordrende å lede. Hvilke utfordringer finnes i tidlig fase av prosjekter, hva er suksesskriteriene for prosjekteringsledelse - og hva kan prosjekteringsledelse lære fra offhore engineering og skipsdesign? Dette er spørsmål som Vegard Knotten stiller i avhandlingen.

Knotten konkluderer med at prosjekteringsledelse må forstås ut ifra sin kontekst. Avhandlingen forslår et generisk rammeverk for håndtering av prosjekteringsledelse i tidlig fase. Prosjekteringsledelsen bør forfølge suksesskriteriene og proaktivt håndtere utfordringer, og på grunnlaget av nøye vurderinger av prosjektet foreslå en strategi for gjennomføring av prosjekteringsledelsen.

Hallgrim Hjelmbrekke disputerte 3. november 2017 ved NTNU for ph.d.-graden med avhandlingen:

«Styring av byggeprosjekter mot strategiske mål. Eierstyring som et virkemiddel for strategisk effekt». 

I avhandlingen stiller Hallgrim Hjelmbrekke spørsmålet: Hvordan kan byggeprosjekter innrette seg etter kundens strategiske og forretningsmessige mål?

For å forstå problemet og å kunne iverksette tiltak, er det utarbeidet en generisk modell for eierstyring. Modellen identifiserer avvik mellom kundens mål og prosjektets leveranser, underliggende årsaker til dette og foreslår fire sentrale tiltak som skal forbedre prosjekteierstyringen.

I utgangspunktet er enhver beslutning om å investere i et nytt prosjekt begrunnet med et ønske om å løse et problem og skape en endring til en bedre situasjon for brukere som igjen gjør det mulig for prosjekteier å høste en gevinst og strategisk nytte. Prosjekter rent generelt lykkes bare til en viss grad å realisere nytte for eier. Investeringer i byggeprosjekter bekrefter dette bildet og preges av mangel på produktivitet, kostnadsoverskridelser, kvalitetsmangler og misfornøyde brukere. Dette indikerer at prosjektenes intensjon om verdiskaping for brukere og nytte for eiere forsvinner underveis i byggeprosessen.

Det er en tydelig trend at når prosjekter mislykkes, så er mangel på eierstyring årsaken til problemet. Hovedkonklusjonen er at det er en mangel på kompetanse og forståelse hos prosjekteier hva angår prosjektets rolle som strategisk verktøy og hva som er de viktigste suksessfaktorer for å høste de strategiske effekter av prosjektene. Samtidig er det avdekket en manglende kompetanse på leverandørsiden (prosjekteringsteam) i forhold til å forstå prosjektets forretningsmessige mål og innrette leveransen innenfor et rammeverk i form av en enhetlig forretningsmodell.

"Spatial quality assessment for energy-efficiency renovation of dwellings"

Spatial quality is the perception of the quality of the physical space. The user perceives spatial quality through the relationships between physical elements. The interface between walls, ceilings, doors, windows and columns, as well as inside and outside spaces under different (day) light conditions all define spatial quality. This PhD research thesis proposes a spatial quality definition, and a measurable and objective assessment framework to evaluate and predict the impact of energy efficiency renovation of dwellings on spatial quality. 

The definition and assessment are based on four spatial quality determinants:

(1) views, (2) internal spatiality and spatial arrangements, (3) the transition between public and private spaces, and (4) perceived density, built and human densities. These spatial quality determinants are developed during the PhD research, based on a literature study on the quality of life in the urban environment, spatiality and spatial perception, energy efficiency renovation of dwellings, and a study of seven actual dwelling renovation cases. The prime reasons why this research has focused on spatial quality are the lack of a clear spatial quality definition on the building scale in the literature, and the sometimes unintended but always unmeasured impact of energy efficiency renovation of dwellings on spatial quality.

Climate change and the urge for sustainability have led the building industry into a radical re-thinking of how they construct new buildings and renovate existing ones. Energy efficiency renovation of dwellings is an opportunity to increase people’s well-being in a dwelling, rather than just improving its technical energy performance. The positive link between the renovation and benefits to people’s everyday life has the potential to increase end users’ acceptance and building owners’ willingness for renovation. The spatial quality definition and assessment developed in this PhD research are intended to strengthen the understanding of the quality of physical spaces in dwellings. The assessment can help to evaluate and predict the effect of energy efficiency renovation on spatial quality in dwellings. It can also help design teams to include spatial quality in energy efficiency renovation, and explore the potential of the renovation to improve the spatial quality in dwellings.

This PhD work has two contributions and two main findings. The first contribution is the spatial quality definition for dwellings. The second contribution is the assessment framework. The first main finding of the research is that energy efficiency renovation affects spatial quality in dwellings, and that the renovation can improve spatial quality, not only energy performance. The effects can be positive, for example, if there are new openings in the facade, or negative if the changes in the plan result in excessively deep rooms in relation to the size of the windows. The second main finding follows from the literature study on the renovation of dwellings, on spatial quality related issues, and from the study of the renovation cases. In order to improve spatial quality in energy efficiency renovation, increased spatial quality may be planned at an early stage of the renovation process together with the increased energy performance.

"The impact of microclimate on biodeterioration of wood in historic buildings"

Bygningsmaterialer i historiske bygninger kan gjennom en langvarig eksponering for ulike klimatiske og mikroklimatiske forhold utsettes for en gradvis nedbrytning av biologiske skadegjørere. Denne studien viser at avgjørende faktorer i forskjellige tilfeller av biologisk nedbrytning i stor grad er temperatur og fuktighet på et mikroklimatisk nivå, helt ned til noen få centimeter rundt vedcellene i treverket. 

Ved bygningsundersøkelser av historiske bygninger kan man ønske seg en god tilgang til historisk informasjon om konstruksjoner, materialer, tidligere bruk, eksponering og eventuelle skader.

Dessverre er slik informasjon sjelden tilgjengelig. Fordi både muggsopp, råtesopp og treskadeinsekter har spesielle krav til økologiske forhold, er etablerte skader et resultat av tidligere langtidseksponering av fukt- og temperaturforhold. Identifikasjon av forekommende arter kan dermed gi avgjørende innsikt om skader. Hvis man kan tolke skadene i henhold til disse forholdene, kan man forstå årsakene til skadeutvikling og dermed også forebygge ytterligere skadeutvikling. Min erfaring er at forutsetningen for biologisk nedbrytning av treverk er universell. Takket være dette kan man i prinsippet vurdere skader fra polområdene til tropene på den samme måten.

De mikroklimatiske forholdene og aktivitet av ulike biologiske skadegjørere har vært undersøkt på fire ulike steder i Norge: Bryggen i Bergen, Lærdalsøyri/Otternes, Røros og Svalbard i forbindelse med ulike prosjekter i løpet av en 20 års periode. Målet med disse studiene har vært å avklare hvordan mikroklimaet påvirker sopp- og insektskader i verneverdige bygninger og trekonstruksjoner – både med hensyn til de faktiske skader og de praktiske konsekvenser skader forårsaker. Fokus har vært på de to mest avgjørende fysiske faktorene for biologiske skadegjørere, temperatur og fuktighet. 

Denne avhandlingen beskriver hvordan mikroklimaet påvirker biologisk nedbrygning av treverk i historiske bygninger. Det er en forhåpning om at disse resultatene og erfaringene bidrar til å forbedre denne kunnskapen i ulike fagmiljøer.

"Daylighting and Architectural Quality: Aesthetic Perception of Daylit Indoor Environments"

The present thesis concerns the field of daylighting in architecture. In particular, this thesis examines the topic of the aesthetic perception of daylit indoor environments.
Most daylighting studies seem to use photometrical measurements to describe the light in a space. Moreover, most studies seem to focus on comparing metrics to establish an adequate illumination for optimal visual and task performance.

However, lighting considerations should go further than merely visual and task performance guidelines; good lighting should also contribute to the aesthetic perception of any environment. This is an important distinction to establish: a room with enough light for performing tasks can be described as an ‘adequately illuminated room’, whereas a room that also provides a pleasant visual environment can be considered a ‘well-lit room’. Yet little literature investigating the aesthetic quality of architectural spaces lit by daylight can be found.

Therefore, the present study seeks to explore how different daylighting designs affect the aesthetic perception of indoor built environments. The fields of architecture and daylighting are taken as starting points. In addition, the aesthetic perception of environments entails studies of environmental psychology, e.g. environmental aesthetics and measurement of environmental perception. Daylight and aesthetic quality are thus terms of paramount importance in the present research. In the scope of the work presented here, two types of daylighting design have been considered in the study: windows as the most basic daylight collectors in buildings (primary daylighting design), and daylighting systems as advanced measures to collect and distribute daylight deeper in interiors (advanced daylighting design).

To examine the aesthetic quality of an architectural space, nine aesthetic attributes were selected:
Pleasantness, Excitement, Order, Complexity, Legibility, Coherence, Spaciousness, Openness, and Spatial Definition.

Luminance-based metrics of countour, shape and detail distinctness of day-lit 3D objects"

Light modelling is a small but important part of the lighting quality concept. It determines not only the capability of the eye to detect any objects in a space but also its ability to discriminate contours, shapes and details, the most important visual characteristics of any object. These are essential and significant indicators that allow a person to analyse and ascertain another person’s state of health, the freshness of food, the mood of the interlocutor and many other key characteristics of visual environments. Thus, light modelling is an essential aspect important in various architectural spaces, from museums to hospitals to offices.

To date, few studies have been dedicated to light modelling. Some basic knowledge has been achieved from studies on pedestrian visibility and road lighting. However, few investigations have been performed in day-lit interiors. Thus, the light modelling topic remains underestimated and insufficiently studied.

To address this gap, the present research aims to develop the concept of light modelling of real 3D objects in day-lit environments. The author will propose the metrics of contour, shape and details distinctness of the examined units as the most critical aspects of light modelling. Based on the idea that light and colour are mentally inseparable in the human perception of visual environments, it is of great importance to create experimental conditions that provide both of these principal concepts (light and colour). The high dynamic range (HDR) imaging technique will be used as part of the experimental research methodology, giving reliable, analysable, numerical data obtained from luminance maps.

Three experiments and their outcomes form the basis of this dissertation. Work on this dissertation began with general research questions regarding studies of chromatic interiors using HDR images, examining the possible effect of achromatic and chromatic colours and colour combinations on the perception of room illumination (Experiment 1). The focus then turned to the development of the appropriate luminance-based metrics of real 3D achromatic and chromatic objects placed in a room illuminated by daylight (Experiment 2). These metrics were then verified in a real room study and repeated through computer simulation (Experiment 3).

The results obtained from these experiments indicate that majority of the proposed luminance-based metrics correlate very well with subjective assessments that deem contour, shape and details to be distinguishable in different degrees. The metrics also indicate considerable variations among 3D objects with different luminance and chromatic contrasts. These luminance-based metrics outperformed currently used modelling index and cylindrical illuminance metrics. Furthermore, these luminance-based metrics can be used both in real architectural spaces and computer simulations.

Considering these advantages, the author of this dissertation proposes that luminance-based metrics should be recommended for practical use to ensure light modelling; specifically, to better guarantee the distinctness of objects’ contours, shapes and details. The metrics have some limitations dictated by existing experimental conditions and therefore require further testing if they are to be made universally applicable. These will be further discussed in the present dissertation, as will some proposals for possible future research.

"Effective energy solutions using facade materials with highly reflective coatings and aerogel granulate glazing systems"

We are facing an urgent problem of reducing carbon dioxide emissions in order to
mitigate climate change. The building sector is a main source of carbon dioxide
emissions. This thesis is trying to contribute to the creation of solutions for this problem
by investigating the application of relatively new building materials, particularly highly
reflective coatings and aerogel granulate glazing facades.

Facades have an important role to play in controlling indoor climate and thus building
energy use. This thesis investigated which facade properties have an impact on reducing
heating and cooling energy demands in a common building type (office building) in
Tokyo, Japan. It was shown that walls with high reflectance and windows with low heat
gain and low heat transmittance can contribute to achieving energy efficient buildings. In
this regard, highly reflective coatings and aerogel granulate glazing systems can make an
important difference. These materials are therefore able to serve as an energy solution.
Highly reflective coatings and aerogel granulate glazing systems are still new products in
the building field. This thesis therefore experimentally provided information concerning
their durability.

"Photovoltaic-thermal systems for zero emission residential buildings"

This thesis concerns the use of solar energy in energy efficient buildings. More precisely, the topic is photovoltaic-thermal (PV/T) solar energy systems, and how these can be used to provide renewable energy in zero emission buildings. PV/T modules are a hybrid between photovoltaic (PV) modules and solar thermal collectors, and therefore generate electricity and thermal energy simultaneously. The objective of the thesis was to investigate the potential of PV/T systems to minimize the life cycle greenhouse gas emissions of a residential building.

The main research method in this thesis has been simulation of solar energy systems in buildings. Using simulations, PV/T systems have been compared to other solar energy systems with separate PV modules and solar thermal collectors. The simulation studies were performed in the simulation programs Polysun and PVsyst, and were based on commercial solar energy products available on the current market. The use of heat pumps, air-source and ground-source, in combination with solar energy systems was also studied.

Two case buildings, the ZEB residential concept and the Living Lab, have been used in the simulation studies. The buildings are two of the pilot buildings of the Norwegian Research Centre for Zero Emission Buildings (the ZEB Centre). Both buildings are single family residential buildings located in Central or Southern Norway, and are designed to meet the Norwegian passive house requirements.

The embodied emissions of the solar energy systems were determined using elements of life cycle assessments (LCA). A review of previous research found few studies of the environmental impact of PV/T modules, especially using industrially produced modules. The embodied emissions of such a PV/T module was therefore determined in this thesis, based on a combination of data from databases and information from module producers. The embodied emissions of the case buildings and the other solar energy systems studied were determined using a combination of databases and previously published research in the ZEB Centre.

The results show that PV/T systems can be a good renewable energy solution for energy efficient buildings, but that their performance is highly dependent on how the system is designed and what control strategies are used. The simulations showed that the systems with PV/T modules typically had higher primary output per unit area than the systems with separate PV modules and solar energy collectors, but that this also depended on how the solar energy systems were designed. However, due to a higher use of electricity to run e.g. circulation pumps, the energy balance of the whole building was not improved compared to systems with separate solar technologies.

"Cleaning services in local authorities"

Denne avhandlingen diskuterer renholdstjenester i kommuner og er et svar på behovet for ny kunnskap innen kommunal eiendomsforvaltning (FM). Forskningen har vært finansiert av Kommunal og regional departementet (KRD). Målet har vært å beskrive og utforske renhold med den hensikt å fremskaffe ny kunnskap som kan bidra til å utvikle og forbedre eiendomsforvaltningen i kommuner. Den gjennomførte forskningen har vært basert på en beskrivende og utforskende fler-metode tilnærming bestående av en grundig litteratur studie, en nasjonal spørreundersøkelse og to case studier. Resultatene er presentert i denne avhandlingen, inklusive vedleggene. Avhandlingen inneholder flere referanser og analyser enn det som fremkommer i de vedlagte, fagfellevurderte publikasjonene. Sett under ett gir avhandlingen en økt forståelse av kommunale renholdstjenesters organisasjon og praksis siden 1800-tallet og frem til i dag.

Fokuset i forskningen har vært på norske kommuner. I tillegg, har det blitt innhentet empiriske erfaringer fra Storbritannia (UK), samt kunnskap fra internasjonal forskning. Tre forskningsspørsmål (RQs) ble formulert for å besvare målsetningen om å studere kommunale renholdstjenesters organisasjon og praksis. Disse tre forskningsspørsmålene muliggjorde 1) oversikt over renholdsrelatert forskning i en norsk sammenheng over en tidsperiode på 200 år, 2) en kvantitativ og nasjonal oversikt over organisatoriske modeller som benyttes for renholdstjenester i norske kommuner fra 1990-tallet og fremover, og 3) kvalitativ og lokal innsikt i to kommuners renholdsorganisasjon og praksis i tidsperioden 2010-2011. Disse to lokale studiene betraktes som eksempler på hvordan renholdstjenester kan organiseres og praktiseres i kommunene, og bør derfor ikke betraktes som eksempler på hvordan renholdstjenester skal organiseres og praktiseres. Eksemplene omfatter strategiske, taktiske og operasjonelle perspektiver. Det mest detaljerte nivået på forskningen omfatter observasjoner av renholdere på jobb.

"Insights into (in)formal land delivery processes -adopting a relational perspective to understand the formation and development of three squatter settlements within Kathmandu, Nepal"

The term informal land delivery processes or simplistically referred to as ‘squatting’ are not new terms, they have been in existence for a long time; however very little in – depth research have been done to understanding exactly how they function – the relationship between the institutions (rules and social norms) and actors involved. Most studies on informal settlements have traditionally centered on how to deal with the “housing problem” in developing countries. The main strategy of this research not centred on how to deal with the “housing problem” but rather (re)search reasons responsible for the existence of this problem in the first place. 
Hence, rather than explaining (limited to looking at the ends), this research aims at describing the means – the causes and the social mechanisms through which urban poverty persists, especially those that fall beyond narrow income – consumption concerns, or individual entitlements mediated by legal and market systems (Mosse, 2010; Gore, 1993; Kabeer, 1994; Green and Hulme, 2005). The main focus therefore is to understand the process of formation and development of three specific squatter settlements in the context of Kathmandu, the capital city of Nepal, one of the least developed countries in South Asia. 
The research takes Marx’s ontology and his conception of method within a relational perspective as a starting point in order to address core issues of inequalities following the path of Burgess (1977; 1997; etc) and other neo Marxists. 
Network analysis is used as a primary basis for understanding the relationship between elements (which in this case are households) that form the totality (squatter settlements). Furthermore, concept of relational social capital is also used to analyze the positions and structures within this totality. 
The research adopts a qualitative, case study method where the three specific squatter settlements are the main case study areas and households are the embedded units of analysis (i.e. the cases). Out of 53 squatter settlements within Kathmandu Valley, three case study areas are selected for this research. In terms of the main unit of analysis – the households, a number of diverse cases from each of the different category of households within the owners and renter/tenants were selected. 
The empirical data for this research was generated over a period of approximately 8 months divided into three main research fieldwork phases. 
This PhD thesis is based on four main Appended Articles, each compiled at the end of three subsequent research fieldwork phases. 
This research is based on three main theoretical perspectives each discussed in the four main articles:

  • informal land delivery processes (Articles I and II)
  • social capital (Article III)  
  • governance/planning in the global south (insurgent planning practices) (Articles IV)

"How Do We Rebuild a Disaster damaged Heritage Settlement: A study of the Post- Earthquake Reconstruction of the Village of Taoping.
A Traditional Qiang Settlement in Sichuan China"

This research is about post-disaster reconstruction of culture heritage settlements, not
as an activity but conceptually, by addressing the question of how do we preserve a
heritage settlement damaged by disaster? Underpinning that issue is a case study of
Taoping Qiang Village. Taoping is a Qiang Minority’s traditional settlement which
went through a post-earthquake reconstruction from 2008 to 2011 in Sichuan, China.
In my thesis heritage settlement is understood as “lived-in cultural heritage
settlements”. The “lived-in” situation refers to heritage settlements which suspends
the natural coherence between inhabitants and dwellings. This coherence refers to
settlements renovate and maintenance according to their needs and wills of their
inhabitants. Which in turn are driven by their livelihoods, social practices and living
habitus etc. “Lived-in” heritage illustrates a state in which the protected old dwellings
host a present-day mode of living. “Lived-in” heritage also displays the coexistence of
habitation and conservation. Furthermore it implies a complicated relationship
between those two actives.
To rebuild a heritage settlement after disaster is not only to rescue the damaged
historical buildings but also to reestablish the homes of the inhabitants. This research
is built on that recognition and regards the local community as a key player in the
reconstruction of heritage settlements. To understand possible behavior and reaction
of the community to the reconstruction we need to know its social context. Hence my
research employs “modernity” and “citizenship” in order to set up a “reference frame”.
The extent of modernity and state of citizenship substantially impact the underlying
attitude and reactions of the community.

"Transparent facades in low energy office buildings. Numerical simulations and experimental studies"

Windows are a key component in the building envelope. They are often, thought of as energy drains and something associated with excessive energy demands in a building. However, in order to assess the energy performance of a window, several factors must be addressed. The most important issues to consider are energy losses due to heat transmission through windows, energy gains from solar radiation as well as transmitted visible light and the influence on artificial lighting demands. Factors like thermal and visual comfort in buildings are additional factors that need to be assessed and addressed. Existing work that has been carried out within this field of topic lacks in addressing two major factors that are important in the context of this thesis:

  • Buildings situated in cold climates.
  • Buildings with highly insulated envelopes.

Thus, the need for further research with these aspects in mind emerges and performance
assessments of the glazed elements by themselves as well as in combination with shading systems have been carried out. Focus has been on both the thermal and optical performance of systems, and systems performance assessments for whole buildings. The objective of this thesis has been to investigate the performance of windows and various window solutions in the context of low- or zero-energy buildings situated in a cold climate. Both state-of-the-art solutions as well as more theoretical studies of what today’s and tomorrow’s windows can look like are studied. Experimental research has been used in combination with numerical simulations to assess and characterize the performance of windows and solar shading devices. The component-level performance characteristics have been used as input to the analysis on the whole building scale for selected case studies. Likewise, the case study results have been used as a baseline for design criteria for components.

"Zero Emission Building Envelopes: The Effect of Insulation and Thermal Masson Greenhouse Gas Emissions"

In a sustainable world, the use of non-regenerating natural resources is in balance with what nature is able to provide in long term. Our way of living has resulted in enormous usage of resources, and it is time to change our attitude and regain the balance. In this context, the main focus the latest years have been global warming caused by greenhouse gas (GHG) emissions. It is therefore important to reduce the GHG-emissions from buildings, not only from the operational phase, but from the whole life cycle.

This thesis presents six papers, where the building envelope has been studied, with main focus on thermal insulation and thermal mass. The advanced products Vacuum Insulation Panels (VIPs) and Phase Change Materials (PCMs) have been given special attention. The basis for the work has been a single-family house with a lightweight wood frame construction, which is a common Norwegian building. The house has been studied at three different levels and in a life cycle perspective:

1. Component level, i.e. the thermal performance of insulation, thermal mass and studs which is part of wall/floor constructions.

2. System level, i.e. the thermal performance of wall/floor constructions.

3. Building level, i.e. the energy performance of the building.

4. Life cycle, i.e. greenhouse gas emissions (GHG) during the life cycle of the house.
