Impact of energy policies on building and ductwork airtightness

Purpose of the work

This paper aims at reviewing and analysing changes and developments in various countries on building and ductwork airtightness in the past 5 years.

Method of approach

Critical steps for a wide scale implementation of building and ductwork airtightness

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.

Building and ductwork airtightness: Selected papers from the REHVA special journal issue on ‘airtightness’

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.

Impact of ductwork leakage on the fan energy use and sound production of central mechanical ventilation units in houses

Various studies demonstrate a significant impact of ductwork leakage on the fan power consumption of ventilation systems. They have shown that the total energy used by fans can be reduced by 30-50% by improving the airtightness of the ductwork system. However, most of those studies focused on non-residential and multi-family buildings. This study focuses on single-family dwellings; specifically houses.
