Within the framework of the BUILT2SPEC project, a new airtightness device suitable for construction sites, is being developed for integration with the Built2Spec Self-Inspection Platform. The output will be available directly on the device itself and exportable to a smart phone app developed for this project. The device operates based on a novel low pressure air pulse airtightness technique by the University of Nottingham which allows testing of occupied buildings with no disruption.

Built2Spec (Built to specifications) is an EU-funded project carried out by 20 European partners. The project aims to revolutionise construction practices by introducing a new set of breakthrough technological advances for self-inspection and quality assurance to the construction site that will be put into the hands of construction professionals to help meeting EU energy efficiency targets, new build standards and related policy goals.

This fact sheet describes how a quality management scheme has been introduced in the French energy regulation to encourage professionals to question their current practice and find effective solutions to improve building airtightness. The scheme allows successful applicants (mostly builders of single-family dwellings) to justify for a given airtightness level without systematic third-party testing. The fact sheet details the basic principles of the approach as well as the requirements applicants have to fulfil.

This study gives a detailed overview of Greenlandic residential buildings from 1957-1963 and describes their condition based on extensive measurements (blower door, thermography, indoor air quality measurements, etc.). The study - conducted for the four most common types of standard houses in Sisimiut, Greenland - found the standard houses in a poor condition, even though they had all to some extent been renovated. The blower door tests showed that the air change rate of the houses were much larger than the limit for new buildings.

The BUILD UP Skills Finland project has collected the best practices of high quality and cost- and energy-efficient construction. The result of the work is a training package of 10 slide shows and a guide for construction sites. The focus areas of the training package are airtight buildings and the functioning of building technology. The material is useful for all operators in the construction industry. Download the free material at

The March QUALICHeCK workshop in Lund—co-organised with TightVent—was a good occasion to witness the progress made in the Member States to foster better envelope and ductwork airtightness and better ventilation system performance. Regulation is clearly the strongest driver, and gets even stronger with converging private initiatives; however, the successful Swedish experience with airtight ductwork and quality ventilation systems shows that it is not the only route to consider.
