    Sammanfattning : The purpose of this work is to contribute to a process formaking buildings with good function and to avoid prematurefaults.The design, construction and installation of low-slopedroofs are important parts of creating a durable building. LÄS MER

  3. 22. Investigating Dwellings' Response to Heating Power Cuts : Simulations and Field Tests

    Författare :Victor Fransson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Reducing energy use, increasing the use of renewable energy sources, and adapting to stricter building regulations and certification systems – these are all examples of the challenges facing the building industry and society. Looking at the energy supply at a larger scale than a single building, like a neighborhood or a city, the stack effect of peak power demands can cause problems on the production side, either economical or concerning the environment and greenhouse gases when fossil fuel is used to cover these peaks.

  4. 23. Primary energy use of residential buildings : implications of materials, modelling and design approaches

    Författare :Uniben Yao Ayikoe Tettey; Leif Gustavsson; Ambrose Dodoo; Jan-Olof Dalenbäck; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; primary energy use; material production; simulation; input parameters; design strategies; climate change; overheating; residential buildings; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering;

    Sammanfattning : Buildings can play an essential role in the transition to a sustainable society. Different strategies, including improved energy efficiency in buildings, substitution of carbon intensive materials and fuels, efficient energy supply among others can be employed for this purpose.

  5. 24. Thermal comfort and energy in residential buildings in a cold climate

    Författare :Petter Lundqvist; Mikael Risberg; Erik Elfgren; Patrik Rohdin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. LÄS MER

  7. 25. Natural Ventilation and Air Infiltration in Large Single‑Zone Buildings : Measurements and Modelling with Reference to Historical Churches

    Författare :Abolfazl Hayati; Magnus Mattsson; Mats Sandberg; Jens Fransson; Guilherme Carrilho da Graça; Högskolan i Gävle; []
