Objective of this study is to provide a better understanding of the compliance of input data related to window thermal performance in EPB declarations for new buildings in the Belgian region of Flanders, and to derive recommendations to improve the … Continue reading
In the federal province of Salzburg, the EPC is necessary in order to receive an energy-related subsidy, and the process follows a two-step procedure: to receive a construction permission, the planning EPC has to be issued and accepted by the … Continue reading
The main objective of the QUALICHeCK project is to respond to the concerns regarding the reliability of Energy Performance Certificate (EPC) declarations and the quality of the works. In order to analyse the situation in the ground, compliance assessment studies … Continue reading
In this report, QUALICHeCK gives an overview of the building energy performance related quality and compliance situation in 9 focus countries: Austria, Belgium, Cyprus, Estonia, France, Greece, Romania, Spain and Sweden. A review of 31 existing studies dealing with measured … Continue reading
The Spanish scheme of Energy Performance Certificates (EPCs) is based on the asset energy performance. The calculations can be carried out by at least three methods, one detailed and two simplified. Different set of default data can be used, for … Continue reading
Building air leakage rate is taken into account in energy calculations, but mainly with default tabulated values. With tabulated values, there is an option to use measured values instead of more conservative tabulated values. Regarding compliance, usually there is no … Continue reading
Thermal bridges calculation rules are addressed in the building codes of all studied countries. Main approach seems to be some kind of simplified system where calculations of thermal bridges is not required. In many cases tabulated or default values in … Continue reading
Summer thermal comfort is somehow addressed in most of the building codes. As it is quite a new issue, it is not fully established and more effort is needed for successful implementation. This fact sheet provides an overview of the situation … Continue reading
The IBO OEKOPASS is an Austrian building certification system specially developed for new residential complexes (multi-unit residential buildings). It aims at voluntarily showing proof of building quality on the basis of building energy efficiency, ecology and indoor comfort principles as … Continue reading
This study gives an overview of the different compliant calculation methods for window thermal performance in the Flemish regulation on Energy Performance and Indoor Climate in Buildings (EPB). The study investigates to what extent input data for window thermal performance … Continue reading
