1. 1. Achieving building energy performance : requirements and evaluation methods for residential buildings in Sweden, Norway, and Finland

   Författare :Ingrid Allard; Thomas Olofsson; Gireesh Nair; Ronny Östin; Osama Hassan; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building codes; energy performance; evaluation methods; air tightness;

   Sammanfattning : Building energy performance has always been important in the cold climate of Sweden, Norway and Finland. To meet the goal that all new buildings should be nearly zero-energy buildings by 2020, set in the EU directive 2010/31/EU [1] on the energy performance of buildings (EPBD recast), the building sector in Europe now faces a transition towards buildings with improved energy performance.

3. 2. Life performance assessment methodologies for combined solar energy technologies : a case study on system parts in nordic climates

   Författare :Bojan Stojanovic; Christer Sjöström; Björn Karlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life performance; assessment; combined solar energy technologies; degradation; component and system performance; Building engineering; Byggnadsteknik; Materials science;

   Sammanfattning : The main questions concerning energy technologies today are their economical and environmental impacts. These entities are (at the present) assessed on the basis that operations proceed as newly installed/designed systems, during an assumed working life period. LÄS MER

4. 3. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

   Författare :Gabriel Auziane; Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

   Sammanfattning : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. LÄS MER

5. 4. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs

   Författare :Kurt Källblad; Institutionen för byggvetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Computer Programs; Windows; Infiltration; Comfort; Walls; Indoor Climate; Climate; Ventilation; Cooling Load; Heating Load; Buildings; Thermal Models; Building Physics; Energy; Byggnadsteknik;

   Sammanfattning : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. LÄS MER

7. 5. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

   Författare :Claes Blomqvist; Mats Sandberg; Per Heiselberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

   Sammanfattning : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.
