Passive solar design is based on the following five principles that optimize the use of solar energy for heating and cooling the living space:
Building orientation towards true south (in the northern hemisphere)
Properly placed, energy efficient windows
Calculated roof overhangs
Thermal mass for energy storage
Thermal efficiency and insulat... |

| | | The solar thermal colectors for heating domestic water work during all year. Suposse that you have a solar system and you decide going holidays and as consequence heat water will be not used, what do you think it would be done with the collectors?

| | | In the case of solar thermal, my answer (mine, not the answer of all partner members) is a gas or a diesel boiler, it depends of the localitation of the building (Diesel system in remote places). Never people must install a electricity system to heating or cooling.
Those auxiliary systems are not RES, however those are neccesaries, but one ... |
