Dans le cadre de la réduction des consommations d'énergies primaires des bâtiments, de nouveaux matériaux de constructions sont amenés à être développés. Les réglementations thermiques poussent les nouvelles constructions à être économes en énergie. Elles doivent aussi être moins impactantes sur l'environnement tout en garantissant le confort des occupants.Dans ce travail est présenté le développement d'un nouveau matériau de construction composite intégrant un matériau à changement de phase (MCP).Les MCP sont capables d'échanger passivement de l'énergie thermique avec leur environnement. Il permettent ainsi une régulation passive de la température intérieure.Suite à un état de l'art, sur les MCP et le plâtre, est présenté la synthèse et la caractérisation physico-chimique d'un nouveau MCP à transition solide-solide.L'incorporation du MCP préalablement synthétisé à un matériau de construction de type plâtre est ensuite développée. Le matériau composite ainsi obtenu est caractérisé thermiquement et mécaniquement.Dans un dernier temps des évaluations environnementales du MCP et du matériau composite sont réalisées. / In a context of reduction of energy consumption in buildings, new buildings materials are developed. Thermal regulations require energy efficiency to buildings. They must be less impacting on the environment while ensuring occupant comfort.In this work is presented the development of a new composite building material incorporating a phase change material.PCM are able to exchange passively heat energy with their environment. It thus allow a passive control of the interior temperature of buildings.After a state of the art on PCM and plaster, a part is dedicated to synthesis and physicochemical characterisation of a new solid/solid PCM. In a third part the incorporation of the PCM previously synthesized in plaster is then developped. The composite material is mechanically and thermally characterized.In a last time environmental assessments of the PCM and the composite material are performed.

Because of the potential for development to have negative environmental impacts, one of the most important questions addressed by environmental law and policy is whether and how to allow development to proceed. In Canada this question is answered primarily through environmental impact assessment ("EIA"). At the federal level, EIAs are required under the Canadian Environmental Assessment Act, S.C. 1992, c. 37 ("CEAA") for certain types of proposed projects and activities. Although CEAA's purposes include fostering both a healthy environment and economy, the Act does not provide any instruction on how to balance or choose between these goals in situations where both goals cannot be served. In 1999 Professor Daniel Farber developed a methodology he refers to as 'eco-pragmatism' in an attempt to create a means by which society's competing (and often contrary) values can be balanced and satisfactory trade-offs arrived at. In this thesis the differences between CEAA and eco-pragmatism are explored and consideration is given to whether eco-pragmatism might assist in resolving the value conflicts that often characterize EIAs. Of particular interest is whether Farber's approach might improve the CEAA framework and assist CEAA decision-makers in determining whether proposed projects should be approved. It is argued that although eco-pragmatism is useful, it is not adequate if the ultimate goal is environmental protection that is sustainable into the future. Both CEAA and eco-pragmatism focus on the mitigation of negative environmental effects, rather than on achieving long-term environmental gains or observing a minimum environmental standard. Accordingly, both arguably have the effect of slowing the erosion of environmental quality, but each fails to observe some sort of environmental 'bottom line' that would impose an ultimate limit on negative impact. It is suggested that an ultimate limit is a necessary (albeit difficult) element of environmental law. / Law, Peter A. Allard School of / Graduate

Tendo em vista a emergência do turismo como atividade de significativo impacto econômico e, conseqüentemente, de potencial impacto negativo ao meio ambiente, o presente trabalho avalia as perspectivas de aplicação da avaliação ambiental estratégica como instrumento de consideração e ponderação das questões ambientais na tomada de decisão e planejamento do turismo no Brasil. Por meio de revisão bibliográfica e de análise da prática internacional, discute a relação turismo e meio ambiente, os instrumentos utilizados para a gestão ambiental da atividade e as experiências de aplicação da avaliação ambiental estratégica em turismo. Além disso, o trabalho traz um estudo de caso no município brasileiro de Bueno Brandão, no estado de Minas Gerais, com o intuito de apresentar o cenário político e institucional local e avaliar as condições e os desafios para uma possível inserção da avaliação ambiental estratégica no plano municipal de desenvolvimento turístico. Conclui-se que, apesar de já existir certo consenso no que diz respeito a princípios e boas práticas de AAE, as experiências internacionais em políticas, planos e programas de turismo ainda apresentam uma série de imprecisões em termos de metodologia, formas de participação e abordagens. Entende-se que, no Brasil, ainda existe uma série de desafios, metodológicos e políticos, para garantir a inserção do meio ambiente na tomada de decisão de forma participativa. Esse fato ficou claro com as questões identificadas no estudo de caso, especialmente aquelas relacionadas aos mecanismos de participação da sociedade, capacitação do corpo técnico, ações de planejamento integradas e articuladas, e produção, sistematização, democratização e monitoramento de informações ambientais, de forma a orientar o planejamento e a tomada de decisão. / Considering the raising of the tourism sector as an activity of significant economic impact and, consequently, potential negative environmental impacts, the present work evaluates the perspectives for application of strategic environmental assessment as a tool which can integrate environmental issues into tourism planning in Brazil. Using bibliographical research and analysis of the international practice, this work discusses the relationship between tourism and environment, the environmental management tools used and the practical experiences of strategic environmental assessment in the tourism sector. Beyond that, the work presents a case study in Bueno Brandão, a brazilian town located in the state of Minas Gerais, in which it discusses the political and institutional setting and evaluates the conditions and challenges for a possible insertion of the strategic environmental assessment in the local tourism development plan. Although it already exists certain consensus in strategic environmental assessment principles and good practices, the international experiences in SEA for tourism planning still presents some imprecisions in methodology, public participation and approaches. It is clear that in Brazil there are still challenges in methodological and political approaches to guarantee the insertion of environmental concerns in the decision making and public participation contexts. This fact was confirmed by the issues identified in the case study, mainly, failures related to the mechanisms of public participation, the qualification of the technical staff, integration of planning actions, and the production, systematization, democratization and monitoring of environmental information, in a way to guide the decision making and local planning.

A definição e o estabelecimento da matriz de transportes de um país são desafios que acarretam implicações ambientais além das sociais e econômicas. No contexto brasileiro existem previsões de incorporar a dimensão ambiental no processo de tomada de decisão no Plano Nacional de Logística e Transporte em consonância com os pressupostos do desenvolvimento sustentável. A Avaliação Ambiental Estratégica (AAE) é um instrumento utilizado internacionalmente para propiciar essa inserção e facilitar a tomada de decisão mais estratégica. Assim, o objetivo da dissertação foi discutir e estabelecer critérios conceituais de boas práticas de AAE, as possíveis contribuições da aplicação de uma AAE nos Planos de Transporte e aplicar no caso brasileiro Plano Nacional de Logística e Transporte (PNLT). Para a consecução do objetivo proposto, o presente trabalho estabeleceu critérios e formulou uma diretriz teórica de boas práticas de AAE a partir da Diretiva Européia 42 de 2001, que trata da implantação e procedimentos de AAE, e de experiências de países como a Escócia, País de Gales e Inglaterra. Esse quadro conceitual foi aplicado no caso brasileiro do Plano Nacional de Logística e Transporte. Os resultados obtidos mostram um fraco compromisso do Plano Brasileiro com um efetivo envolvimento da dimensão ambiental no processo de tomada de decisão, evidenciando um descompasso entre o que é preconizado e a prática. A principal conclusão é que o Plano Nacional está direcionado para o crescimento econômico sem a devida inserção da dimensão ambiental. / The definition and the establishment of transport matrix of a country challenges that cause environmental implications as well as social and economic. In the Brazilian context, there are predictions of incorporating environmental considerations into decision-making in the National Plan of Logistics and Transport in line with the assumptions of the sustainable development process. The Strategic Environmental Assessment (SEA) is a tool used internationally to provide this integration and facilitate more strategic decision making. The aim of the thesis was to discuss and establish conceptual criteria of good practice SEA, the possible contributions of applying SEA in Transport Plans and apply the Brazilian case - National Plan of Logistics and Transport (NPLT). To achieve the proposed objective, this paper established criteria and formulated a theoretical guideline of best practices from the European SEA Directive 42 of 2001 that deals with the establishment and SEA procedures, and experience of countries such as Scotland, Country Wales and England. This conceptual framework was applied in the case of Brazil\'s National Plan of Logistics and Transport. The results show a weak commitment of the Brazilian Plan with an effective involvement of the environmental dimension in the decision-making process, showing a gap between what is recommended and practice. The main conclusion is that the National Plan is directed to economic growth without proper integration of the environmental dimension.

A consideração da variável ambiental nos processos decisórios do planejamento tem sido um desafio para diversos países. Nesse sentido, a Avaliação Ambiental Estratégica (AAE), instrumento que tem por objetivo inserir questões ambientais no planejamento de políticas, planos e programas, vem se consolidando no cenário internacional e tem sido cada vez mais praticada, inclusive em países em desenvolvimento como o Brasil. Nesse contexto, essa dissertação compara a situação atual da AAE no Brasil em relação à situação apresentada em México, Espanha, Inglaterra, África do Sul e Brasil. Para isso, foi utilizado o método comparativo qualitativo, que avaliou cada um desses sistemas com base em categorias descritivas e seus respectivos critérios de análise. As categorias selecionadas para caracterizar os sistemas de AAE foram Formal/legal, Institucional, Acadêmica e Prática. Os resultados demonstraram que os sistemas de AAE estudados apresentaram padrões diferentes de desenvolvimento e evolução ao longo do tempo. África do Sul, México e Brasil apresentaram evidências de experiências práticas e também interesse institucional que têm motivado a implementação formal desse instrumento nesses países. Contudo ainda apresentam lacunas em relação à estruturação formal e institucional desta ferramenta, afetando a qualidade de suas experiências práticas. Por outro lado, apesar de algumas limitações, os sistemas de AAE de Espanha e Inglaterra se apresentaram mais estruturados e desenvolvidos, fornecendo evidências empíricas sobre a relevância das esferas institucionais e acadêmicas para o seu desenvolvimento. De maneira geral, a comparação realizada nesta pesquisa demonstrou que existem diferentes formatos de sistemas de AAE, de acordo com o país ou contexto no qual é aplicada. / The insertion of environmental issues in decision-making has been a challenge in many countries. Therefore, Strategic Environmental Assessment (SEA), an instrument that aims to embed environmental issues in the planning of policies, plans and programs, has now been consolidated and increasingly practiced in the international arena, including developing countries, like Brazil. In this context, this dissertation compares the current status of SEA in Brazil in relation to the situation presented in Mexico, Spain, England and South Africa. A qualitative comparative method, which evaluated each system based on descriptive categories and their criteria was used for the analysis. The categories selected to characterize the SEA systems were formal/legal, administrative/institutional, academic/conceptual and practical/applied. The results have showed that the SEA systems studied present different patterns of development and evolution along time. South Africa, Mexico and Brazil have showed evidence of different practical experiences and also institutional interests, which have motivated the formal reception of this instrument in those countries. However they still present some gaps in relation to formal and institutional structure of SEA, which affect their practical experience. On the other hand, despite some limitations, the SEA systems of Spain and England are more structured and developed, providing empirical evidence of the relevance of institutional and academic spheres to their development. In general, the comparison conducted in this research has showed that there exist different system formats to SEA, depending on the country or context in which it is applied.

This licentiate thesis examines environmental assessment tools for buildings. This is done by investigating, analysing, comparing and testing how different environmental assessment tools measure the environmental performance of buildings and examining the consequences this may have on architectural design. The study begins by analysing three environmental assessment tools: Leadership in Energy and Environmental Design (LEED), Code for Sustainable Homes (CSH) and EcoEffect. These tools are then tested on a case study building (an eight-storey residential building) to analyse differences regarding assessment results, improvement proposals and potential impacts on architectural design. One of the environmental impacts assessed in the three tools, namely Climate Change caused by gases having Global Warming Potential (GWP), is then analysed in greater detail from a life cycle perspective by measuring CO2-equivalents (CO2-eq). A basic calculation tool (referred to as the ENSLIC tool), based on life cycle assessment methodology, is used to assess a case study building (a four-storey office building in Gävle). The CO2-eq emissions from a building’s material production and energy use are calculated and the impacts of a number of suggested building improvements and changes of energy sources are analysed.  The studies show the complexity of assessment tools and different ways to make comparisons. Both similarities and differences between the tools are apparent, regarding hierarchical structure and also on each hierarchical level, from categories to issues and parameters. It is also shown that the choice of environmental assessment tool may have an influence on the architectural design of buildings. The difficulty with assessing complex buildings is apparent even when only one environmental issue is assessed with the LCA-based ENSLIC tool. Many aspects influence the assessment result. These include energy use, choice of materials and choice of energy sources. The complexity and difficulty in linking buildings to environmental impact create a need for interactive tools measuring environmental performance, which can be useful as decision support in the early design phase. / Denna licentiatavhandling behandlar miljöbedömningsmetoder för byggnader. Arbetet bygger på undersökningar analyser, jämförelser och tester av hur miljöbedömningsmetoder bedömer byggnaders miljöprestanda och undersöker även vilka konsekvenser som detta kan ha på arkitektonisk utformning. Forskningen börjar med att tre miljöbedömningsmetoder, Leadership in Energy and Environmental Design (LEED), Code for Sustainble Homes (CSH) och EcoEffect analyseras och jämförs. Sedan genomförs en fallstudie där de tre metoderna testas på ett bostadshus (ett åttavåningar högt bostadshus i Stockholm). Skillnader gällande miljöbedömningsresultat och miljöbedömningmetodernas förslag på förbättringsåtgärder samt eventuell påverkan på den arkitektoniska utformningen analyseras och diskuteras. En av miljöpåverkanskategorierna som bedöms i de tre metoderna, klimatpåverkan orsakad av gaser med inverkan på den globala uppvärmningen, analyseras sedan mer i detalj utifrån ett livscykelperspektiv genom att mäta byggnaders utsläpp av koldioxidekvivalenter (CO2 ekv). Ett förenklat beräkningsverktyg (som här benämns ENSLIC-verktyget), som är baserat på livscykelmetodik, används för att studera en byggnad (ett fyra våningar högt kontorshus i Gävle). Sedan beräknas utsläppet av CO2 ekv från byggnadens material- och energianvändning. Effekten av ett flertal föreslagna förbättringsåtgärder på byggnaden samt byte av energikällor analyseras också. Studierna visar på miljöbedömningmetodernas komplexitet och presenterar olika sätt att göra jämförelser på. Skillnader och likheter mellan metoderna påvisas gällande hierarkisk struktur och även på varje hierarkisk nivå, från kategorier till enskilda bedömda frågor och parametrar. Dessa skillnader talar för att olika metoder kan påverka den arkitektoniska utformningen av byggnader. Svårigheten i att bedöma komplexa byggnader belyses även när endast en miljöpåverkan bedöms med det livscykelanalys baserade ENSLIC-verktyget. Många saker påverkar resultatet, framförallt energianvändning tillsammans med materialanvändning och val av energikällor. Den komplexa och svåra uppgiften att länka samman byggnader med deras miljöpåverkan öppnar upp för användande av interaktiva verktyg som mäter miljöpåverkan som kan användas som beslutshjälpmedel i tidiga designskeden. / QC 20101123

The Swedish Act on Municipal Energy Planning was written in 1977 in a time of energy crisis and requires each municipality to have a plan for rational supply and distribution of energy. With regards to the on-going climate change however, there is a need for energy planning to emphasise on shifting towards an efficient energy system with high share of renewables, and low impacts on the climate and the environment. The legislation is therefore argued to be outdated and is currently under review. This study shows that most municipalities are working with the energy issue, as 71% have adopted a policy document with focus on energy and climate. However, 41% has not adopted an energy plan as referred to in the Act on municipal energy planning. The results show that the energy strategies have a wider focus than what is stated in the legislation, which strengthens the view that the legislation can be regarded as outdated. Energy Strategies however still have an important function at the municipal level, as they can help to integrate energy aspects into spatial planning, as well as function as support for the daily energy and climate work in the choice of strategies and measures. The study further shows that the use of Strategic Environmental Assessment has potential to increase the consideration of environmental quality objectives, especially those that might be impacted from the energy plans, but the use of it has been fairly limited and only conducted in 6% of the energy plans. It is therefore recommended that the Act on Municipal Energy Planning is revised to instead include requirements for municipal energy and climate strategies, and that they are made subject to Strategic Environmental Assessment, thus promoting a transition to a sustainable energy system, where environmental objectives are taken into account and possible conflicts can be addressed early in the planning process. / Med beaktande av klimatförändringarna finns ett stort behov av att energiplaneringen har ett holistiskt och strategiskt förhållningssätt med hänsyn till klimat- och miljöpåverkan. Kommunerna har en viktig roll i utformandet av den hållbara staden på grund av sitt planmonopol, och ska även enligt lag ha en aktuell energiplan. Lagen om kommunal energiplanering skrevs dock vid en tid av energikris och fokuserar mer på tillgång och distribution av energi än ett hållbart energisystem. Kommunala energiplaner omfattas även av det så kallade SMB-direktivet och som huvudregel ska en strategisk miljöbedömning göras för samtliga energiplaner. Det övergripande syftet med denna studie är att undersöka nuvarande praxis för kommunal energiplanering, genom att kartlägga kommunernas energistrategier antagna under åren 2004-2015. Vidare studeras ifall strategisk miljöbedömning ökar hänsyn till nationella miljökvalitetsmål relaterade till energi och om kommunal energiplanering har influerat översiktsplaner genom mål och strategier. Kartläggningen visar att de flesta kommunerna arbetar med energifrågan, då 71 % har antagit någon form av policy-dokument med fokus på energi och klimat inom tidsintervallet. En tämligen stor andel (41 %) har dock inte antagit en energiplan såsom lagen åsyftar. Intervjustudien stärker även bilden att kommunerna har ett vidare fokus än vad som anges i lagen om kommunal energiplanering, och att lagen därmed är utdaterad. Energistrategierna fyller dock viktiga funktioner på den kommunala nivån, dels för att de kan bidra till att integrera energiaspekter i fysisk planering, men även som stöd i det dagliga energi- och klimatarbetet vid val av strategier och åtgärder. Strategisk miljöbedömning har gjorts i ganska begränsad omfattning, för cirka 6 % av energiplanerna. Resultat från intervjuer pekar på att de inte har ökat hänsyn av miljökvalitetsmålen i någon större utsträckning, men däremot fungerat som en försäkran för att de beaktades. De kvantitativa resultaten pekar dock på att för miljökvalitetsmål som inte har en så tydlig koppling till energi och klimat, men där negativa miljökonsekvenser likväl kan uppstå, så ökar strategisk miljöbedömning att dessa tas i beaktande. Det är därför rekommenderat att lagen om kommunal energiplanering revideras till att istället omfatta krav på kommunala energi- och klimatstrategier, och att strategisk miljöbedömning görs för dessa. På så vis främjas en omställning till ett hållbart energisystem, där miljökvalitetsmålen beaktas och eventuella målkonflikter kan behandlas tidigt i planeringsprocessen.

This thesis gives a systematic description of theEnvironmental Load Profile (ELP), an environmental assessmenttool developed for the urban environment. The purpose of thework was to improve the stringency of the system boundaries andfunctional units of the tool. This was achieved by putting theELP structure in the context of Life Cycle Assessment (LCA)with a special emphasis on system boundaries. To create animproved scientific base for the ELP, a comparative study wasconducted using an evaluative framework for conceptual andanalytical approaches. Here, the ELP tool is compared with foursimilar environmental assessment tools for the builtenvironment. Since, energy use in the operation phase is an importantfactor for the overall environmental performance of buildings,a sensitivity analysis was performed to investigate how theselection of heat and electricity mix affects the results of anenvironmental assessment of buildings. Four modes ofelectricity production and two modes of heat production wereapplied on three buildings with different technical systems intheir heat supply. The results show that the choice ofelectricity mix has a great influence on the outcome of anenvironmental assessment (EA) and it is suggested that both anaverage and marginal electricity mix should be applied inEA´s of the built environment. Further, it is argued thatconsequences of assumptions made should be explicitlycommunicated in the EA report, to allow the decision-makersrather than the analysts to make the final evaluation. The ELP is primarily developed to follow up theenvironmental goal‘twice as good’and assess theenvironmental performance of Hammarby Sjöstad, a newcity-district in southern Stockholm. The city-district is builtas a continuation of the inner Stockholm and the first part ofthe project, called Sickla Udde, is nearly finished. The ELPtool was applied in a first case study to answer the questionof how far Sickla Udde has reached in achieving the goal. Theassessment indicates that compared to a reference districtbased on the technology used in 1990, the environmentalperformance of Sickla Udde has reached the goal‘twice asgood’for some environmental load categories and 30percent for others. Although these findings are preliminary,they indicate a development in the right direction. Measurestaken contributing to largest environmental improvements are: amore efficient energy production (improved district heating)and use (e.g. lower U-values in the buildings, energy efficientappliances, heat exchange of ventilation air) and improvedsewage treatment. The results also demonstrate that theenvironmental load from domestic transports can be of the samemagnitude as from the buildings situated within thecity-district. Hence, resources spent to decrease environmentalload in the planning process should primarily be divoted toimproving domestic transportation systems and on optimising theoperational phase of the buildings. <b>Keywords:</b>environmental assessment, urban district,environmental load profile, Hammarby Sjöstad, life cycleassessment, LCA, environmental management, builtenvironment / NR 20140805

The increased demand for fast deliveries of goods have led to more costly and less environmentally friendly transports since many of the delivering trucks are not being fully loaded. The inefficiencies of deliveries have created a need for development of new freight systems. One alternative vehicle that has gained increasingly interest is usage of UAVs (unmanned arial vehicles), also known as drones. Several drones in varying sizes and configurations are being developed and applications within transports of both people and goods is seen as promising areas for the future. The study aims at investigating the performance of drone deliveries regarding time, cost, and environmental impact and to see what parameters are important for the performance. This have been made by comparing a UAV to two different vans (electric and HVO) for parcel deliveries in four chosen missions in both urban and rural settings. The evaluation takes a future perspective and are based on information received through both literature review and a market investigation.  The result from this study indicates that UAVs are likely to be a competitive future option for parcel deliveries regarding time and cost. This is concluded since the results shows significant savings in both costs and delivery time and these results are not changed by the sensitivity analyses. The result regarding environmental performance shows that the UAVs competitiveness depends on the vehicle of comparison. The drone has a better environmental performance than vans with fossil-based propellants but given the energy intensity of the UAV, it is not favourable compared to an electric van. The energy requirement of the drone is one of the most important factors affecting the performance. The energy requirements per km for the UAV increases when the routes become shorter since different phases of the flight have different energy intensity. The most demanding phase is lifting and when the distance between the stops is reduced this phase becomes more prominent. Another important factor is the possibility to reduce the travelled distance by taking the straight path with the UAV compared to being bound by the road infrastructure. The shorter distance for the UAV contributes both to reduced time but also reduced energy requirements which in its turn affect both environmental and economic performance. The distances and energy requirements are thus not the most important factor for the economic sustainability but rather the cost of staff. Since the drones are unmanned, several UAVs could be controlled by the same operator contributing to reduced cost of staff. The low energy requirements for the UAV in the longer and more rural cases makes this type of applications the most beneficial regarding environmental performance. Urban missions are instead the most preferable regarding cost and time, since a bigger share of the distance can be saved and the difference in speed between the UAV and the van is larger.

Byggbranschen befinner sig mitt i ett paradigmskifte – detta i samband med att BIM kommer att ersätta de traditionella arbetsmetoderna inom byggprocessen. BIM, även kallat objektsbaserad informationshantering, används idag till 3D-projektering, visualisering och samordning. Dock utnyttjas inte BIM till sin fulla potential. Förändringar sker även beträffande miljöaspekter inom byggsektorn. Miljökrav är inte längre enbart lagstadgade, utan kommer även från fastighetsägarna själva. En anledning är den ökade miljömedvetenheten, och att byggbranschen är en viktig aktör för en hållbar utveckling. Genom en byggnadsmiljöcertifiering styrs byggproduktioner mot att bli mer miljöanpassade. Miljöbyggnad är en av de vanligaste certifieringarna i Sverige då den är anpassad efter svenska byggregler. Ett av bedömningskriterierna för Miljöbyggnad är att dokumentera byggprodukter som byggs in i byggnadsverket i en loggbok. Det är byggnadsentreprenören som uppför denna och bär ansvaret för Miljöbyggnadscertifieringen under produktionen. Detta examensarbete utreder hur loggbokshanteringen för miljöcertifieringen Miljöbyggnad kan effektiviseras och optimeras inom ramen för BIM. Det första skedet av examensarbetet ägnades åt identifikation av problem kring arbetet med loggboken genom enkätundersökningar och kompletterande muntliga samtal.  I det andra skedet intervjuades BIM-sakkunniga med syftet att söka praktiskt genomförbara tillämpningar av BIM inom loggbokshanteringsprocessen. Kartläggningen resulterade i ett flertal problematiska områden inom den nuvarande loggbokshanteringen. Denna kan dock effektiviseras genom att byggföretag etablerar en konsekvent arbetsmetodik, definierar loggboksprocessen samt inför erfarenhetsåterföring. Utförda intervjuer resulterade i förslag på möjliga effektiviseringar av loggboken med hjälp av BIM – både en lösning som är tillämpningsbar idag och tre framtida lösningar. Den lösning som fått namnet ”Excellista med GUID” kan tillämpas idag, och effektiviserar loggboksprocessen genom att utnyttja den BIM-modell som tas fram under projekteringsskedet med hjälp av unika kodsträngar. Automatiska mängdavtagningar för byggprodukter är ett exempel på en effektiviserad loggboksprocess. Tre lösningar är tänkbara för framtida materialdokumentation inom BIM: En applikation, integrerade systemplattformar eller företagsgemensam databas. Framtidslösningarna kan effektivisera avsevärt genom en automatiserad loggboksprocess. Loggboken inom BIM-modellen skapar möjlighet till spårbarhet och visualisering. Den eliminerar kostsamma och tidskrävande moment i jämförelse med dagens hantering. Slutsatsen är att byggföretaget ska satsa på en företagsgemensam databas för företagets alla systemplattformar, men framtiden för materialdokumentation inom BIM ligger i en väl integrerad lösning mellan BIM-modellen och ett PLM-system. / The AEC industry is in the midst of a paradigm shift - this in conjunction with BIM replacing traditional working methods within the construction process. BIM, also called object-oriented information management, is currently used for 3D modeling, visualization and coordination. However BIM is not being utilized to its full potential. There are also occurring changes regarding the environmental aspects of construction. Environmental requirements are not only legal, but are now requested by the clients themselves. One reason for these changes is increased environmental awareness and another is the fact that the construction industry has a vital role in sustainable development. Environmental certification of building projects promotes an environmentally friendly production. ‟Miljöbyggnad” is one of the most common certifications in Sweden because it is adapted to the Swedish building regulations. One of the assessment criteria for ‟Miljöbyggnad” is the logbook documentation of all the building materials used. It is the contractor who is responsible for the logbook and for the environmental building certification during the production.                   This thesis investigates how logbook management for environmental certification can be efficient and optimized in the context of BIM. The first stage of the thesis was devoted to the identification of problems related to logbook management. This was done with the use of surveys and complementary interviews. In the second phase BIM experts were interviewed in order to find practical applications for BIM in the log management process. The survey revealed several areas of concern within current logbook management. However these problems can be resolved if construction companies can establish a consistent work methodology, define the logbook procedures and implement experience feedback. Analysis of the interviews resulted in suggestions for possible streamlining of logbook procedures using BIM –one solution which is possible to implement today and three for future use. The solution which has been named "Excel list with GUID" can be applied today. Here, the BIM model generated during the design stage, is used to streamline the logbook process with the help of unique reference numbers. Automatic quantity take off for construction products is an example of a streamlined logbook process. Three solutions are possible for future material documentation in BIM: An application, integrated computing platforms or a company shared database. In the future results can be considerably improved with an automated logbook process. The logbook within the BIM model creates the opportunity for traceability and visualization. It eliminates costly and time-consuming steps in comparison with todays logbook management. The conclusion is that construction companies should invest in a company-wide database for all computing platforms, but the future of material documentation with BIM exists in an integrated solution with the BIM model and a PLM system.
