Avhandlingen behandlar byggprocesser i södra Sverige som hade ambitionen att åstadkomma lågenergihus liknande den tyska passivhusstandarden. Syftet med avhandlingen är att öka förståelsen för processer i införandet av ett energikoncept. Energikonceptet betraktas som en innovation för användning i en sektor som av många beskrivs som konservativ och inte särskilt mottaglig för innovationer. Byggprocesserna studeras genom att händelser rekonstrueras med hjälp av berät-tande källor såsom intervjuer och protokoll från olika möten. Även observationer har använts där tillfälle funnits. Fokus riktas mot hur arbetet organiserades och beslutsprocessen bakom valet av teknik till konceptet. Även massmedias rapporte-ring om byggprocesserna har studerats och hur deltagarna i byggprocesserna marknadsförde energikonceptet. Införandet av energikonceptet kan förstås som transformationer eller om-formningar. Omformningarna bestod av fem grundläggande aktiviteter som med Hägerstrands tidsgeografiska begrepp kallas: lösgörning, formning, hopsättning, transportering och lagring. Energikonceptet lösgjordes från ett specifikt lokalt sammanhang och transporterades till ett annat där det formades för att passa nya förutsättningar och sattes ihop till ett nytt energikoncept. Det nya energikonceptet lagrades i ett nytt hus. Genom att följa människors och teknikers trajektorier kunde slutsatser angående energikonceptets svagt och starkt kopplade delar dras. De starkt kopplade delarna är byggherrens organisering av arbetet som skulle underlätta en starkare styrning. Sinnliga upplevelser av lagrade energikoncept hade betydelse för användandet. Solfångare visade sig vara en svagt kopplad teknik och behövde teknikbärare för att användas. / This thesis explores building processes in the south of Sweden with the aim to accomplish low energy housing in accordance with the German standard for passive houses. In this thesis, the passive house is regarded as an innovative en-ergy concept which has been introduced to Sweden and to a conservative sector. The purpose of the study is to provide an understanding of processes in the im-plementation of an innovation for energy-saving dwellings. The process is recon-structed with data from interviews, minutes, articles, reports, etc, and presented as stories of different sequences including how the housing projects were organised, how the energy concept was established among the participants, how decisions were made and what messages were presented about the energy concept in mass media. The energy concept is followed in a process of transformation where it was subject to five fundamental acitivites: decomposition, moulding, composition, transportation and storage. The concepts originate from a time-geography per-spective, founded and developed by the Swedish geographer Torsten Hägerstrand. The energy concept was decomposed at a specific local context and transported to another, where it was moulded and composed into a new energy concept. The new energy concept was stored in a new setting. By following the trajectories of peo-ple and technologies, conclusions about the energy concept can be drawn. The building proprietors chose less conventional ways of managing the building proc-ess in order to have more control. The projects were started by people who them-selves had their own experience of passive houses. Solar collectors were loosely coupled to the energy concept and needed technology carriers.

Com isso percebemos o surgimento de um conjunto de práticas e procedimentos visando as chamadas 'construções sustentáveis', que introduziram uma nova realidade comercial no segmento da construção civil. Para avaliar se uma construção é ou não sustentável surgiram os eco-labellings, que através de sistema de pontuação ou conceitos permitem avaliar qualitativamente em que grau de sustentabilidade uma edificação encontra-se. Em especial, o mercado brasileiro vem, desde 2004, buscando a certificação ambiental LEED; sendo assim, a presente dissertação tem como objetivo identificar, após quase uma década desde a primeira submissão de projeto brasileiro ao USGBC, quais ainda são as dificuldades enfrentadas no processo de certificação LEED. O referencial teórico reforçou que o segmento da construção civil contribui de duas formas para a degradação do meio ambiente: no consumo de recursos naturais e energéticos, e na geração de grande quantidade de resíduos. Por esse motivo, estudos nessa área são extremamente importantes para a transformação do meio ambiente, que, através da adoção de práticas construtivas sustentáveis poderá minimizar os impactos gerados. Neste trabalho, optou-se pela utilização de pesquisa exploratória quanto aos fins, uma vez que existe pouco conhecimento acumulado sobre a avaliação do processo de certificação LEED, e bibliográfica, complementada com pesquisa de campo, quanto ao meio, pois fundamenta-se em estudo desenvolvido com base em material publicado, complementado por entrevistas no campo. Este trabalho caracteriza-se por se um estudo introdutório à compreensão do tema e convida a estudos complementares mais abrangentes, dada a relevância do assunto nas três esferas de sustentabilidade: social, ambiental e econômica. / Concern about the depletion of natural resources and awareness of sustainability issues led the study in an industry that has been shown to be important for the transformation of the environment: construction. Thus we see the emergence of a set of practices and procedures for so-called 'sustainable buildings', which introduced a new commercial reality in the construction segment. To assess whether or not a building is sustainable eco-labellings emerged that through scoring system or concepts allow qualitatively evaluate the degree to which sustainability is a building. In particular, the Brazilian market has, since 2004, seeking LEED certification, so in this thesis aims to identify, after nearly a decade since the first submission to the USGBC Brazilian project, which still are the difficulties faced in the process LEED certification. The theoretical stressed that the construction industry contributes in two ways to the degradation of the environment: the consumption of energy and natural resources, and the generation of large amounts of waste. Therefore, studies in this area are extremely important for the transformation of the environment, which, through the adoption of sustainable building practices can minimize the impacts. In this work, we chose to use exploratory research as to the purposes, since there is little accumulates knowledge on the evaluation of the LEED certification process, and literature, complemented with field research, about the middle, because is based on a study supported on published material, supplemented by interviews in the field. This work is characterized by an introductory study to the understanding of the topic and invites further studies are more comprehensive, given the relevance of the subject in the three spheres of sustainability: social, environmental and economic.

Tato práce se zaměřuje na představení městské zeleně jako důležitý prvek udržitelné výstavby, a především jako prvek, který zbavuje okolní vzduch znečištění a přispívá k lepšímu prostředí ve městech. Dále se tato diplomová práce zabývá vztahem mezi městskou zelení a znečištěním ovzduší oxidem uhličitým v Brně. Ve městě byla prováděná měření koncentrací oxidu uhličitého, kyslíku a sekundárních veličin po dobu půl roku od června do listopadu roku 2019. Měření byla prováděna na čtyřech místech v Brně a dále tato data byla mezi sebou porovnána. Dále byla navrhnuta zelená opatření. Ve dvou vybraných lokalitách v Brně byly vybrány střechy, na které byla navrhnuta extenzivní zelená střecha.

The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.
