1. 1. Thermal Modeling of Walls, Foundations and Whole Buildings Using Dynamic Thermal Networks

   Författare :Eva-Lotta Wentzel; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walls; weighting functions; Dynamic thermal networks; building; dynamic heat conduction; foundation; step-response functions;

   Sammanfattning : The modeling of the energy balance of buildings is a major task in building physics. A new theory called dynamic thermal networks is under development at the Building Physics Research Group at Chalmers. The calculations are based on step-response functions, and the problems are illustrated in so-called dynamic networks. LÄS MER
