Sauna

Minergie is theoretically a fantastic, environmentally friendly way of making a building more energy-efficient, by reducing the need for air conditioning and heating. For three years now I have been playing with and experimenting with minergie. During the first and second heatwaves, I liked to open windows and get fresh air. I found that Minergie means “poor air circulation”. As soon as you close the windows you feel the heat radiate from the walls as if they were sauna stones.
