Diretrizes para seleção tecnológica de vedações verticais externas de edifícios em estrutura metálica. / Guidelines for technology selection of external walls of steel structural buildings.

Silva, Carla Andrade da 30 May 2016 (has links)
A publicação da Norma de Desempenho (ABNT NBR 15.575:2013) e a intensificação das discussões sobre o meio ambiente têm trazido ainda mais destaque para as demandas de desempenho, sustentabilidade e construtibilidade nos projetos de edifícios. Se a inserção dessas demandas em projeto é um desafio, sua obtenção durante a execução do edifício é ainda mais difícil, sobretudo ao se considerar o processo tradicional que ainda domina a produção. Por outro lado, a industrialização do processo construtivo, facilitada pela utilização de tecnologias pré-fabricadas, tem potencial de atender às exigências de desempenho, sustentabilidade e construtibilidade. O arquiteto, enquanto profissional atuante desde o início do processo de projeto, é protagonista da seleção tecnológica, com capacidade de influenciar na adoção de um processo produtivo mais industrializado. Para discutir como o arquiteto pode melhorar sua postura frente às demandas de desempenho, sustentabilidade e construtibilidade, ocupando seu papel de agente integrador no processo de projeto, este trabalho aborda as tecnologias construtivas pré-fabricadas para vedações verticais externas (VVE) de edifícios em estrutura metálica. O objetivo principal deste trabalho é propor diretrizes para seleção tecnológica de VVE de edifícios em estrutura metálica, para o desenvolvimento do projeto de arquitetura, considerando os objetivos do empreendimento e as exigências relacionadas a desempenho, sustentabilidade e construtibilidade. A realização deste trabalho adota duas estratégias de pesquisa: revisão bibliográfica e entrevistas com projetistas de arquitetura e incorporador, com experiência na adoção de estrutura metálica e tecnologias pré-fabricadas de VVE em seus projetos. Como resultado, são propostas: diretrizes voltadas para o processo de projeto de arquitetura, incluindo recomendações para a organização da empresa de projeto que busca tomar decisões sobre tecnologias de VVE pautada em requisitos técnicos; diretrizes para identificar se o empreendimento está inserido em \"nichos estratégicos\" e se o \"ambiente\" para sua realização é favorável à adoção de tecnologias construtivas pré-fabricadas; e diretrizes para atendimento às exigências de desempenho, sustentabilidade, construtibilidade e legislação e normas técnicas a serem seguidas pelos projetistas de arquitetura. Conclui-se que, para responder às demandas de desempenho, sustentabilidade e construtibilidade, buscando adotar tecnologias construtivas pré-fabricadas de VVE, são necessários ao projetista de arquitetura: participação, de fato, na etapa de execução do edifício; estabelecimento de parcerias com agentes envolvidos no processo do empreendimento; manter-se atualizado quanto à legislação e normas técnicas (que têm revelado a tendência de não restringir ao uso de tecnologias construtivas tradicionais); especificar por desempenho as tecnologias de VVE adotadas em projeto; acompanhar a evolução das informações sobre o impacto ambiental gerado pelas tecnologias de VVE; e adotar os princípios de Coordenação Modular nos projetos. / The publication of NBR 15575: 2013 and the growing discussion about environment have brought even more emphasis on some specific demands, such as performance, sustainability and constructability in building projects. Considering that including these demands on design is a challenge, during the building construction is even more difficult, especially regarding the traditional process, which still dominates the production. On the other hand, the industrialization of construction, facilitated by usage of prefabricated technology, has potential to meet performance, sustainability and constructability requirements. The architect, an active professional since the beginning of design process, is the protagonist of technology selection and able to influence the choice for a more industrialized construction process. In order to discuss how an architect could improve his job when it comes to performance, sustainability and constructability demands, assuming an integrating agent role on design process, this research approaches the prefabricated technologies for external walls of steel structural buildings. The main purpose of the research is to propose guidelines for technology selection of external walls of steel structural buildings, aiming the architectural design development, considering the project goals and requirements related to performance, sustainability and constructability. Therefore, two research strategies have been chosen: literature review and interviews with architectural designers and developer, experienced in adopting steel structure and prefabricated technologies for external walls on their projects. As a result of this, it is proposed: guidelines oriented for the architectural design process, including recommendations to organize the design company which seeks for selecting technologies for external walls driven by technical requirements; guidelines to identify if the project is included on \"strategic segments\" and if the \"environment\" for its execution is advantageous to the adoption of prefabricated building technologies; and guidelines to meet performance, sustainability, constructability, legislation and technical standards requirements to be followed by architectural designers. In conclusion, to meet performance, sustainability and constructability demands, aiming the adoption of prefabricated building technologies for external walls, there are some specific needs for architectural designers: active participation on building execution phase; establishing partnerships with stakeholders during the development process; be up to date on the legislation and technical standards (which have been showing a trend to do not restrict the usage of traditional building technologies); to specify by performance the technologies for outside walls chosen on the project; follow the information development about environmental impact generated by outside wall technologies; and adopt the principles of Modular Coordination on the projects.

Ytterväggars energiflexibilitet och klimatpåverkan : En jämförande studie

Christianson, Anton, Swedin, Robin January 2024 (has links)
The transition to renewable energy for heating of buildings is limited due to load peaks during the heating season which also requires fossil energy during peak hours. Increased energy flexibility by utilizing building thermal mass is considered as a cost-effective solution to this problem by storing energy from off-peak hours to be used during peak hours. This study evaluates how five different types of external walls (concrete, lightweight concrete, light expanded clay aggregate, cross laminated timber and wooden frame) enables energy flexibility by simulating the thermal autonomy for a multi-storey building depending on U-value and climate conditions in Sweden, while also considering their environmental impact from the production process through a life cycle assessment during stage A1-A3. The result shows that a concrete wall has the biggest flexible potential and wooden frame the lowest, while there is no significant difference between the rest. Considering the combination of the actual required thermal autonomy, in this case 15 hours, and environmental impact for each case, walls of cross laminated timber and wooden frame can be seen as the overall best option for southern Sweden. Despite the biggest environmental impact, concrete can be seen as the best option for northern Sweden. / Det riktas idag stort fokus på att samhället ska bli fossilfritt till 2040, därbyggsektorn är en bransch som står för en stor del av koldioxidutsläppen;uppvärmning av bostäder i Sverige utgör ca 40% av den totalaenergianvändningen. Ett sätt att öka användningen av förnybar energi föruppvärmning är att utnyttja byggnaders energiflexibilitet genom att lagravärme i byggnadens termiska massa. Syftet med denna studie är att jämföra hur fem olikaytterväggskonstruktioner (betong, lättbetong, lättklinker, KL-trä och träregel) bidrar till byggnadens energiflexibilitet samt klimatpåverkan från produktskedet A1-A3 för att avgöra hur respektive ytterväggskonstruktionlämpar sig med hänsyn till båda dessa faktorer. Dessutom studeras hur olika U-värden och geografisk placering påverkar jämförelsen. Detta görs genomatt simulera byggnadens termiska autonomi i TRNSYS då värmesystemet stängs av vid kl 6:00 på morgonen. Klimatpåverkan beräknas med Byggsektorns miljöberäkningsverktyg i termer av CO2-ekv/m2. Slutligengörs en sammanvägd jämförelse med hänsyn till både energiflexibilitet och klimatpåverkan i ett scenario där gränsvärdet för termisk autonomi är 15 timmar. Resultatet från studien visar att en yttervägg av betong är klart mestenergiflexibel i alla scenarion och en träregelyttervägg minst, medan det inte är någon betydande skillnad mellan övriga. Vad gäller påverkan av U-värdeoch geografisk placering innebär lägre U-värde och mildare klimat att effekten av större mängd termisk massa blir större, vilket innebär att energiflexibiliteten för betongytterväggen växer ytterligare i jämförelse med övriga konstruktioner. För klimatpåverkan under livscykelskedet A1-A3 innebär en betongyttervägg störst koldioxidutsläpp, medan ytterväggar av KL-trä och träregel har lägst klimatpåverkan. Vid den sammanvägda bedömningen av energiflexibilitet och klimatpåverkan med hänsyn till att flytta energianvändningen till nattid visar studien att ytterväggar av KL-träoch träregel är tillräckligt energiflexibla i södra Sverige, vilket gör de totalt sett bäst lämpade. I norra Sverige innebär dock det kallare klimatet att betongytterväggen är bäst lämpad trots störst klimatpåverkan.
