Monitoring and Simulation of a Passive House with Innovative Solar Heat Pump System
Abstract
The very low energy demand of passive houses, which has been proven by measurement, is in the range of the target of the Nearly-Zero-Energy directive. Hence, the foundation of a development is already laid today which will be introduced in Europe in 9 years (the recast Energy Performance of Buildings Directive, EPBD, Directive 2010/31/EU). Due to the very high level of thermal insulation and the resulting very low heating demand and heating load, passive houses show a well balanced load duration curve. The domestic hot water demand can be covered with a high fraction by solar energy. However, solar heating of passive houses is under most circumstances poorly effective as the heating demand is confined to few months in main winter.
