  1. 6. 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

    Sammanfattning : Energy consumption for heating and ventilation of buildings is still in 2011considered far too high, but there are many ways to save energy and construct lowenergy buildings that have not been fully utilised. This doctoral thesis has focused onone of these - low temperature heating systems. LÄS MER

  5. 9. Sustainable building ventilation solutions with heat recovery from waste heat

    Författare :Behrouz Nourozi; Sture Holmberg; Adnan Ploskic; Qian Wang; Shia-Hui Peng; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater heat recovery; balanced mechanical ventilation; defrosting reduction; heat recovery efficiency; thermal load shifting; renewables; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. LÄS MER
