Passive Cooling published an informative article about how to keep cool without costing the planet. The amount of energy used for cooling buildings has doubled worldwide since 2000, making it the fastest growing end-use for energy in buildings. We can’t afford to continue this trend.

There are four ways for passive cooling: educe the heat gain entering a building, remove interior heat through ventilation, store the relative cool in thermal mass, and create air movement to make the space feel cooler.

Specific strategies for both hot and humid and hot and arid regions are outlined. Keeping the heat out in the first place is primary, and effective shading is advised. Adequate venting is essential.

There are many details outlined in the article, and I think it is worth reading.

  1. The EB house I’m building (almost dried in now) has the back half made by nesting a crescent shaped wall inside another larger crescent shaped wall. The 2 walls connect at the corners. The back wall is sprayed with closed cell foam and will soon be backfilled up to the living roof. With no doors currently on the building and only half the windows, that back room is 20f cooler in summer and 20f warmer in winter. Can’t wait to see how it performs when completed.
