FACT SHEET #38 | Compliance assessment studies in focus countries

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

FACT SHEET #35 | QUALICHECK Study Spain – Different data/tools for getting EPCs

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

FACT SHEET #33 | Building air leakage rate in energy calculation and compliance procedures

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

FACT SHEET #32 | Requirements and compliance related to thermal bridges

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

FACT SHEET #31 | Summer thermal comfort requirements and compliance assessment frameworks

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

FACT SHEET #27 | The Austrian building certification system IBO OEKOPASS

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

FACT SHEET #25 | Compliant EPC input data for window thermal performance: Status for new buildings in Flanders, Belgium

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

FACT SHEET #21 | Quality framework for reliable fan pressurisation tests

Airtightness performance of the building has a significant weight in the Belgian EPB-calculation and the number of pressurisation tests in new buildings is strongly increasing. To face the potential lack of tester’s skills and to ensure a reliable value, a … Continue reading

FACT SHEET #20 | QUALICHECK Study Sweden – Compliance of Energy Performance Certificates (EPCs): differences between measured and calculated energy use in EPCs versus building permits

The Swedish scheme of Energy Performance Certificates (EPCs) is based on the measured energy performance. The energy use should be corrected for non-normal use during a reference year. There is no defined methodology to take non-normal use of domestic hot … Continue reading

FACT SHEET #19 | QUALICHECK Study Romania – Assessment of quality and compliance in the certification of energy performance of buildings

The QUALICHeCK study Romania investigated the quality and compliance of Energy Performance Certificate (EPC) input data, based on analysis of EPC received in the central collection point and introduced in the structured database, as well as on the analysis of … Continue reading
