Don't be deceived by appearances!
Appearances can be deceptive. These five small buildings (or test cells) all look the same from the outside and even from the inside. They are also built in a way that should ensure that they have the same amount of heat loss through the walls, floors and roofs. However, the walls of these buildings contain the following, completely different thermal insulation materials: hemp-lime; mineral wool; polyisocyanurate; wood fibre; brick; and block cavity wall.
These buildings are put to the test in the rugged environment of a decommissioned military airfield in Wroughton, United Kingdom, where they are exposed to extreme wind flow and temperature conditions.
Let’s see which one of these takes the least amount of energy to maintain a comfortable indoor temperature!
