  1. 1. The ORC method

    Författare :Jan Akander; KTH; []
    Nyckelord :;

    Sammanfattning : The ORC Method (Optimised RC-networks) provides a means ofmodelling one- or multidimensional heat transfer in buildingcomponents, in this context within building simulationenvironments. The methodology is shown, primarily applied toheat transfer in multilayer building components. LÄS MER

  3. 2. Impact of Radon Ventilation on Indoor Air Quality and Building Energy saving

    Författare :Keramatollah Akbari; Jafar Mahmoudi; Öman Robert; Sylvia Waara; Jan Akander; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Industrial living is caused much people do live and work in closed and confined places; offices and residential buildings. This is why in this new world more fresh air which is generally provided by forced ventilation plays a vital role in living of human being. LÄS MER

  4. 3. Evaluation of Thermal Comfort and Night Ventilation in a Historic Office Building in Nordic Climate

    Författare :Hossein Bakhtiari; Mathias Cehlin; Jan Akander; Abolfazl Hayati; Patrik Rohdin; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; historic buildings; office buildings; Nordic climate; thermal comfort; field on-site measurements; standardized questionnaire; building management system BMS ; night ventilation NV ; building energy simulation BES ; IDA-ICE; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Envelopes with low thermal performance are common characteristics in European historic buildings resulting in insufficient thermal comfort and higher energy use compared to modern buildings. There are different types of applications for the European historic buildings such as historic churches, historic museums, historic theatres, etc. LÄS MER

  5. 4. A System Perspective on Energy End-Use Measures in a District Heated Region : Renovation of Buildings and Hydronic Pavement Systems

    Författare :Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Jan Akander; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A district heating and cooling (DHC) system can be a viable piece of the puzzle in the efforts of reducing the greenhouse gas (GHG) emissions. Especially if the DHC system include combined heat and power (CHP) plants which enable electricity production from renewable resources. LÄS MER

  7. 5. On the Effect of Occupant Behavior and Internal Heat Gains on the Building’s Energy Demand : A case study of an office building and a retirement home

    Författare :Jakob Carlander; Bahram Moshfegh; Jan Akander; Shahnaz Amiri; Sture Holmberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; energy efficiency indicators; occupant behaviour; energy performance; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : About 12% of the greenhouse gas emissions and 40% of the total energy use in the EU derive from the buildings. User behavior, construction, and HVAC systems has a significant impact on a building’s energy use. If a building is to be energy-efficient it is important to understand how all these parameters are connected. LÄS MER
