1. Heating and Cooling Requirements in Commercial Buildings. A duration curve model including building dynamics
Sammanfattning : In many European countries, especially, the heat loss due to transmission and air leakage, in many buildings today, is only a fraction of what it was in those built in the early 70's. At the same time there have been changes in the way the buildings are used which, among other things, has lead to an often considerable increase of the internal heat loads. LÄS MER
2. Climate and Energy Use in Glazed Spaces
Sammanfattning : Glazed spaces ranging from small glazed verandas to large atrium buildings have become a common feature in architecture. A glazed space is greatly affected by aspects of the outside climate such as insolation and temperature. LÄS MER
3. Particle Emissions from District Heating Units Operating on Solid Biofuels
Sammanfattning : With the increasing interest in the use of biofuels for heat and energy generation there is a growing concern about emissions from their combustion. It has been shown that biofuel furnaces emit relatively high quantities of particulate matter in comparison to natural gas and light fuel oil furnaces. LÄS MER
4. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs
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
5. Konvertering av direkteluppvärmda flerbostadsområden-Beslutsunderlag och drivkrafter
Sammanfattning : The Swedish society is interested in reducing the use of electricity and especially electricity for heating purposes. For this purpose governmental subsidies have been introduced to support a change from electric heating to other types of heat supply systems. Owners of single and multifamily buildings can apply for the investment subsidy. LÄS MER
