The impact of auxiliary energy on the efficiency of the heating and cooling system: Monitoring of low-energy buildings

摘要: Abstract This paper presents a detailed meta-analysis of end and primary energy use for heating, cooling ventilation 11 low-energy non-residential buildings one residential building in Germany that belong to the EnOB research program launched by German Federal Ministry Economy. In particular, analysis emphasizes substantial impact auxiliary on efficiency heating performance. The investigated employ environmental sources sinks – such as ground, ground water, rainwater ambient air combination with thermo-active systems. These concepts are promising approaches slashing without violating occupant thermal comfort. A limited about 100 kWhprim/(m2neta) target complete service technology (HVAC lighting) was postulated all presented. With respect this premise, comprehensive long-term monitoring high time resolution carried out over course two five years, an accompanying commissioning Measurements include cooling, ventilation, well equipment, performance heat source sink, local climatic site conditions.
