This approach to building, which was pioneered in Germany, maximizes the use of passive measures (or solutions) to reduce the energy need using insulation in the design of the building. Strict limits on energy use for heating, cooling, and thermal comfort are applied as a criterion to focus on efficiency first.
High-quality insulation is central to passive construction, creating an optimal indoor climate by minimizing the need for active heating and cooling. In the House, architects exclusively used ROCKWOOL stone wool products. A 280mm thickness of CAVITYROCK® semi-rigid insulation boards as well as AFB® and ROCKBOARD® are used to wrap the building in an insulated blanket.
