Sammanfattning : The solving of crucial global energy challenges hinges on improving energy efficiency in building energy systems. Accomplishing energy-efficiency targets often entails incorporating sustainable energy sources into the energy supply system. LÄS MER
Sammanfattning : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. LÄS MER
3. 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
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
Sammanfattning : Hybrid electric and full electric vehicles have attracted growing attention during the last decade. This is a consequence of several factors, such as growing environmental concerns, increasing oil prices and a strive for oil independency. LÄS MER
