Summary report

This summary report provides a synthesis of the work on the building and duct airtightness issue. The conclusions and recommendations are presented in part A. These constitute the most important result of the project. Part B gives an overview of all other project material related to that topic, which allows you to easily identify the information most pertinent to your interest at any time. Part C lists the project partners and sponsors.

Stimulation of good building and ductwork airtightness through EPBD

One of the issues addressed by ASIEPI is to give a clear picture to policy makers regarding the way better envelope and ductwork airtightness is stimulated in the member states, including indications on the impact of the measures taken to transform the market. The purpose of this report is to present the work done in this work package and the acknowledgments dressed through the different deliverables and productions, from October 2008 until March 2010.

Synthèse du questionnaire ASIEPI : État des pratiques européennes concernant l’étanchéité à l’air de l’enveloppe et des réseaux (in french)

This report gives an overview of the mechanisms that have lead to a market transformation on envelope and ductwork airtightness in five countries - France, Germany, Finland, Belgium, Norway - and emphasize the key elements that could inspire other member states. It consists in a collection of papers written by participants to the ASIEPI project at the end of 2008. It gives an interesting insight into success stories end difficulties to overcome. It is available in French only.

An overview of the market transformation on envelope and ductwork airtightness in 5 European countries

This report summarizes the results of a questionnaire submitted to 13 experts in the 13 countries (BE, CZ, DE, DK, ES, FI, FR, GR, IT, NL, NO, PL, PT) represented within the ASIEPI consortium in November 2007. The survey included 22 questions dealing with the way envelope and ductwork airtightness is taken into account in the regulation; the market uptake of better envelope and ductwork airtightness and reasons behind; and the major barriers towards better airtightness.

Report on the building airtightness measurement method in European countries

The fan pressurisation method, described in the European standard EN 13829:2000, is usually used to determine the building airtightness in the context of the regulations on energy performance of buildings. However, this standard describes different variants of measurement (for example method A, B, etc.).

In the framework of the ASIEPI project, a survey has been made of the existance of additional specifications to this standard for the envelope airtightness measurement in EU countries. The results are reported in this paper, which reflects the state at the time of the enquiry, i.e. mid 2008, and which present also the additional specifications to the standard developed in Belgium in the context of the EPB-regulation.

Methods in the national EPB-calculation procedures to determine the ventilation heat transfer coefficient

This report gives an English translation or a summary description for 8 European countries of the manner in which the airtightness of the envelope is taken into account as part of the overall heat transfer through ventilation. For most countries also some background information is given. This analytical overview is complementary to some quantitative comparisons that have been made in another report and in a conference paper.

Brainstorming document on the envisaged ISO 9972 revision

In its meeting of 4 May 2009 in Zürich, the working group ISO/TC163/SC1/WG10 has decided to launch the revision process of the ISO 9972:2006. It was also decided that the revision work should be conducted in the harmony with related standards, i.e. the EN 13829 (working group CEN/TC89), which is currently based on the ISO 9972:1996 with modifications.

In the framework of the IEE-ASIEPI project a brainstorming has been initiated on possible improvements to these standards.  The present state of discussion is described in this paper.
