The winners of the first ever Passive House Component Award, with a total of twelve passive house windows set to receive recognition at the International Passive House Conference later this month. The real winners, however, are the building owners, as the results of this international competition demonstrate that it's possible to save money with highly efficient building components. Manufacturers offered their products at retail prices including installation for an example building. For each of the four categories - PVC, wood, wood/aluminium, and aluminium - the overall investment and energy costs saved in comparison with standard windows were the decisive factor. The awards will be presented at the International Passive House Conference taking place from 25 to 26 April in Aachen, Germany.
