This is a great introductory book describing the ways Passive House techniques have been implemented on various buildings in Europe cost effectively. There are many color pictures as well as detail drawings showing the thermal bridge-free construction techniques that provide a comfortable living environment without negatively impacting the architecture of the building. There are nine buildings presented, not only do they have great energy performance, but can be built within the financial requirements of low-cost housing. CEPHEUS is a European-wide consortium of experts dedicated to Passive House techniques. Out of print!
