This ebook, produced by TightVent Europe, includes a number of publications from the Intelligent Energy Europe programme and its predecessor, namely from the ASIEPI project, SAVE-AIRWAYS, and SAVE-DUCT projects.

This ebook includes a number of selected papers from the 33rd AIVC-2nd TightVent conference held in October 2012 in Copenhagen.

The 2002 Energy Performance of Buildings Directive (EPBD) already indicated the potential importance of airtightness. With the 2010 EPBD recast and its ambitious 2020 targets, there is even more pressure on these aspects since for most European climates and countries, good envelope and ductwork airtightness levels are necessary to achieve nearly zero-energy buildings.

This report summarizes the work of the initial working phase of IEA ECB Annex 62 Ventilative Cooling and is based on the findings in the participating countries. The report is an official Annex report that describes the state-of-the-art ventilative cooling potentials and limitations, its consideration in current energy performance regulations, available building components and control strategies and analysis methods and tools.

This summary report presents insights on recommendations into how ventilative cooling is integrated in EN standards, ISO standards, national standards, national legislation and national compliance tools. The information presented derives from feedback by IEA EBC Annex 62 experts of 11 countries (see Table 1) who have completed a questionnaire. This gives a high level of insight into the current status, and thereby the recommendations to be given on the basis of this knowledge.
