All buildings in Estonia, that have acquired a construction permit since 1 July 2009, have to comply with regulation no. 68 “Minimum requirements for energy performance”, that also regulates verification of summer thermal comfort compliance in buildings. The objectives of … 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 European building stock lacks energy efficiency, and efforts in increasing the renovation rate and improving the energy performance of buildings have not yet resulted in the intended impact. Although the Energy Performance Certificate (EPC) was introduced to facilitate energy-efficient … 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
To avoid overheating in new buildings, Estonia has introduced a room temperature simulation based procedure and requirements as part of the Energy Performance Certificate (EPC). Although the methodology for compliance assessment was proven to be sound and robust, this relatively … Continue reading
