    Sammanfattning : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. LÄS MER

  3. 2. Low-Temperature Heating and Ventilation for Sustainability in Energy Efficient Buildings

    Författare :Arefeh Hesaraki; Sture Holmberg; Bahram Moshfegh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-temperature heating system; Energy savings; Seasonal thermal energy storage; Variable air volume ventilation system; Indoor air quality;

    Sammanfattning : In 2013, the building sector consumed approximately 39 % of the total final energy use in Sweden. Energy used for heating and hot water was responsible for approximately 60 % of the total energy consumption in the building sector. Therefore, energy-efficient and renewable-based heating and ventilation systems have high potential for energy savings. LÄS MER

  4. 3. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Författare :Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Nyckelord :Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.
