The measurement of air infiltration rates in large enclosures and buildings.

Submitted by on Thu, 04/03/2014 - 15:38

The report discusses the need for a proven method of measuring air infiltration rates in large enclosures in order to assess the need for and effectiveness of energy saving measures. The object of the research is to develop such a proven method. Some

Ventilation of dwellings and air heating

Submitted by on Wed, 04/02/2014 - 14:28

This paper mentions the problems encountered in highly insulated flats and houses as a result of inadequate ventilation. Based on this the advantages of a system for ventilation with heat recovery are presented. In the second part of the paper such a ventilation system is presented combined with an air heating system.

Right and Tight: What’s New in Ductwork and Building Airtightness?

Submitted by on Mon, 02/10/2014 - 11:32

Legislative drivers and new research on the importance of building and ductwork airtightness are leading to increased activity in this aspect of building energy performance. Qualification schemes for competent testers, training and events and where to find the best information are summarised here.

Research into the effect of improving airtightness in a typical UK dwelling

Submitted by on Mon, 02/10/2014 - 11:28

The UK’s Airtightness testing & Measurement Association (ATTMA) is a trade body that represents the UK’s leading air-tightness testing and consultancy firms. Most of the work undertaken by these firms is for the builders of new housing and buildings, who are required to prove that they have achieved the required level of air-tightness in their buildings in order to satisfy Building Regulations.

Stimulation of good building and ductwork airtightness through EPBD

Submitted by on Mon, 02/10/2014 - 10:55

Building and ductwork leakage are detrimental to energy conservation, comfort, and hygiene. They can cause building damage and it can prevent proper control of the ventilation airflow rates. Through the ASIEPI project, we have identified that while some key elements for a market transformation on envelope airtightness are under development in many countries, status quo seems to prevail for the duct market. With the objective of all new constructions being “nearly zero energy buildings” in 2020, policy makers need to know how better airtightness can be stimulated.
