WEBINAR #10 | Ventilative cooling potential and compliance — Status and perspectives in Spain and Germany

1 December 2016 Ventilative cooling—i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces—can be very effective to reduce the cooling energy demand in buildings, under summer or mid-season conditions. This webinar is part of a broader … 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

FACT SHEET #18 | QUALICHECK Study Greece – Compliance with the reference values of the technical directives: on-site measurements of ventilation, temperature and relative humidity and comparison with the reference values of the national technical guides

Within the Greek framework for Energy Performance Certificates (EPCs) the methodology is based on a calculation tool with specifications according to the directives of the Technical Chamber of Greece and to the Energy Performance of Buildings Regulations (K.En.A.K.). The Ministry … Continue reading

FACT SHEET #17 | QUALICHECK Study Greece – Compliance of Energy Performance Certificates (EPCs): comparison of the implemented U-values as reported in the EPC with the design U-values for door/window frames and external insulation

Within the Greek framework for Energy Performance Certificates (EPCs) the methodology is based on a calculation tool with specifications according to the directives of the Technical Chamber of Greece and to the Energy Performance of Buildings Regulations (K.En.A.K.). The procedure … Continue reading

FACT SHEET #16 | QUALICHECK Study France – compliance of regulatory and design studies on energy performance of new buildings

A regulatory calculation is mandatory in France in order to assess the energy performance of all new buildings. Although the comparison with a forecast calculation tool showed low differences, some improvements can be suggested. … Continue reading

FACT SHEET #15 | QUALICHECK Study Estonia – Summertime overheating prevention requirements and compliance assessment

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

FACT SHEET #14 | QUALICHECK Study Cyprus – Compliance of Energy Performance Certificates (EPCs): differences between calculated U-values in EPCs versus actual U-values

Energy Performance Certificates (EPCs) in Cyprus are based on the calculated energy performance. The stated U-values in the EPCs, which are calculated before construction of a building, should be corrected after construction. There is no requirement to resubmit the EPC … Continue reading
