Abstract

The energy policy in Europe regarding buildings and the energy efficiency sector, are regulated by two directives: 2002/91/CE - EPBD and 2006/32/CE - EEESD [2]. The CEN has elaborated a standard to revise all European normatives about building energy performance and HVAC plants. The "CEN Umbrella" CEN/TR 15615 [3] includes a new version of EN ISO 13790:2008 [4] and a new standard about Heating Plant, use and contributions of renewable energy sources. Furthermore, the CEN Standard provides a software version for technicians. In this paper we present a Round Robin Test between a selection of softwares applied to an Italian case study. The selected calculation methodologies, range from research packages to extra simplified software. Furthermore, the Italian procedure described in UNI-TS 11300 [5] has been analyzed and considered as the reference for all other calculation methodologies. The results of the Round RobinTest show the relationship between thoroughness of data input and energy evaluation accurancy. The more the input data is affected by uncertainty, the less precise is the energy efficiency calculation. On the other hand the energy performance of building evaluation accurancy depends on the aim of the simulation: the energy audit, the energy design or the energy labeling (certification).
