thermal loads

The integration of renewable energies in the dwellings is a solution to diminish their energy consumption. It also could represent important money savings for the owner, if the design and the control of the devices are correctly set up. Numerical simulation environments are powerful tools, which help to develop such design and ontrol procedure. The software TRNsys 16 was used to study the entire energy consumption during seven months of the model of a dwelling using thermal collectors and photovoltaic panels.

The software bSol addresses to the professionals (engineers and architects) eager to optimize the parameters of a building project according to the local environment.

The study of a hotel to be built under the mild climate of Madeira Island, Portugal, is presented. The program DOE-2.1E was used for the thermal load simulation, using as climatic input a Typical Year file constructed for this case. The simulation for the base building showed low heating loads and high cooling loads, of which a very important fraction derives from solar gains.
