Last week I wrote here how I plan my off-grid house to be built. Today I will explain in more details my ideas on how to supply heat to the house, how to ventillate it and how to make domestic hot water. In my climate the most of the energy our houses use goes to […]

Most people probably at this moment think about solar thermal collectors for domestic hot water, but there are many other possibilities. Of course I will write about solar collectors, though it’s not a device I suggest […]

Thermal mass on the interior of the building is able to store heat or cold, and then slowly release it back out to the surrounding air. Heat from a sunny winter day as well as the coolness of a summer night can be retained inside the insulated shell of the exterior walls if the building […]
