Plus Energy Buildings - Technical and Economic Principles

Plus energy houses, i.e. buildings that produce more energy than they consume, will play a key role in the imperative implementation of a future energy supply system. This study shows how competitive plus energy buildings can be implemented through combining photovoltaic systems with electrical systems of heat supply. Plus energy houses are technically feasible and economically successful. They are a concrete technical option. This residential buildings concept could thus serve as a basis for future legal requirements.
