Straw as an insulation material! Sounds crazy? It's actually pretty smart! Benjamin Krick from the Passive House Institute did just that: He insulated his own house, a Passive House, with straw.

Both will be presented by Soraya Lopez from the Passive House Institute at the 25th International Passive House Conference. 

Stay cool - that's easier said than done, especially during heat waves!
