Component Catalogue for Building a Passivehaus

More than 20 years ago, when the first residential building was constructed according to the passive house criteria in Kranichstein, Germany, the general public would not have believed that this concept would become a legally-required minimum standard in the not so distant future. Comments like “That‘s like living in a plastic bag!” or “The expenditure, the costs ... that‘ll never be worth it!” were the rule rather than the exception. However, increasing energy costs, a shortage of raw materials and global warming caused rethinking so that previous rejections have been replaced by interested building owners looking for answers and solutions.
