1. 1. 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

3. 2. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach

   Författare :Gery Einberg; Sture Holmberg; hazim Awbi; KTH; []
   Nyckelord :Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER

4. 3. Energy efficient and economic renovation of residential buildings with low-temperature heating and air heat recovery

   Författare :Marcus Gustafsson; Sture Holmberg; Chris Bales; Jonn Are Myhren; Rahmatollah Khodabandeh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik; iNSPiRE;

   Sammanfattning : With the building sector accounting for around 40% of the total energy consumption in the EU, energy efficiency in buildings is and continues to be an important issue. Great progress has been made in reducing the energy consumption in new buildings, but the large stock of existing buildings with poor energy performance is probably an even more crucial area of focus.

5. 4. Energy Efficient Renovation Strategies for Swedish and Other European Residential and Office Buildings

   Författare :Marcus Gustafsson; Sture Holmberg; Jonn Are Myhren; Chris Bales; Jarek Kurnitski; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; renovation; low-temperature heating; air heat recovery; district heating; heat pump; Energieffektivitet; renovering; lågtemperaturuppvärmning; värmeåtervinning; fjärrvärme; värmepump; Byggvetenskap; Civil and Architectural Engineering; Energy and Built Environments;

   Sammanfattning : The high energy use in the European building stock is attributable to the large share of old buildings with poor energy performance. Energy renovation of buildings is therefore vital in the work towards energy efficiency and reduced environmental impact in the EU. LÄS MER

7. 5. Energy and Indoor Environment in New Buildings with Low-Temperature Heating System

   Författare :Arefeh Hesaraki; Sture Holmberg; Guangyo Cao; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The aim of this thesis was to evaluate new buildings with low-temperature heating systems in terms of energy consumption and thermal comfort, and to pay some attention to energy savings and indoor air quality. To reach this aim, on-site measurements as well as building energy simulations using IDA Indoor Climate and Energy (ICE) 4 were performed. LÄS MER
