Where can I find an overview of the reports from the EU Member States to describe their national calculation procedures, according to EPBD:2018, Annex 1?
National Annexes or National Datasheets to describe the national method in terms of the Annexes A of the five so called overarching EPB standards (acc. to EPBD:2018, Annex 1*)) are included in the national report to the European Commission and not necessarily made publicly available. *): See also FAQ “How can EU Member States follow […]
If the set of EPB standards is used in different countries, will -for a given building- the energy performance rating be the same for each country?
No. Each EPB standard is unambiguous, however allows specific choices to be made at national/regional level for accommodating differences in climate, building tradition, policy and user behaviour. Example 1: The energy performance depends much upon the outdoor climate (e.g. temperature and solar radiation). Using different climates leads to different results. Example 2: Each country/region can […]
Where at the EPB Center website can I find an overview of National Annexes and National Datasheets for different countries?
At the page on National Annexes we are collecting examples, as far as made available for publication at the EPB Center website. See also FAQs “Are all … available?” and “Where can I find …” 2020-03-03
There are several possible choices and alternatives in the EPB standards. Doesn’t this hinder the comparability and harmonization of the methods?
Having explicit and traceable options in a common methodology is a rational way to take into account national or regional differences in climate, legal context, building tradition and building use. The Mandate M/480 from the European Commission to CEN explicitly asked to develop a harmonized but flexible methodology. Such differences will indeed hinder the international […]
Is there a guide or model to describe the national calculation procedures, as required by EPBD Annex 1?
Yes, an extensive guide how to fill in National Annexes or National Data Sheets is available at the website (link). The Guide comprises tips (“do’s and don’ts”), worked out examples and tips. The Guide also contains recommendations. e.g. on: How to differentiate national choices for different applications How to clearly mark the differences in national […]
Is the set of EPB standards mandatory in Europe?
Annex I to the EPBD sets out a common general framework for calculating buildings’ energy performance and, inter alia, describing national methodologies. To meet the objectives of energy efficiency policy for buildings, energy performance certificates (EPCs) should be made more transparent by ensuring that all necessary calculation parameters, both for minimum energy performance requirements and […]
To describe the national calculation procedures, as required by EPBD Annex 1, do we have a choice between National Annexes or National Datasheets?
If the template of Annex A of the EPB standard can be filled in without any violation of the template and without de facto altering the provisions of the EPB standard, a National Annex or a National Datasheet may be used. See FAQ on the difference between these two options. A National Annex to the […]
Why can’t we just use widely available and more sophisticated dynamic building simulation tools instead of the set of EPB standards?
The reason we can’t simply replace the EPB (Energy Performance of Buildings) standards with widely available dynamic building simulation tools lies in several key factors: 1. Regulatory Consistency and Comparability The EPB standards provide a harmonized framework that ensures consistent and comparable energy performance assessments across different buildings, regions, and countries. If everyone used different […]
For the purpose of EPBD implementation, is there any possibility to provide national policy makers or regulators free access to the set of EPB standards?
The EPB standards are protected by CEN and/or ISO copyright. There is no specific agreement between the EC and CEN to give national policy makers or regulators free access to the standards for the purpose of EPBD implementation. 2019.07.22
For the description of the national calculation procedures, as required by EPBD Annex 1, why is it important to follow the template of Annex A of the EPB standards?
If a certain part of the national calculation procedures is fully based on the relevant EPB standards, then the national choices logically follow the template of Annex A of the relevant EPB standards. In other cases this may not be 100% possible. Nevertheless, it is important to follow the template as much as possible, because: […]
