New innovative low pressure airtightness device for construction sites under development. BUILT2SPEC project

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.

37th AIVC - 18th ASHRAE - IAQ 2016 joint Conference: Call for papers

A call for papers is now open for the IAQ 2016 conference, Defining Indoor Air Quality: Policy, Standards and Best Practices, co-organised by ASHRAE and AIVC. The conference will take place from 12 to 14 September 2016 at the Crowne Plaza Old Town Alexandria, in Alexandria, Va. The conference programme will include internationally acclaimed keynote speakers, original peer reviewed papers, the latest in indoor environmental quality control, plus workshops and panel discussions.


QUALICHeCK FACT SHEET #01: Building regulations can foster quality management — the French example on building airtightness

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.

Energy efficient renovation of standard houses in Greenland

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.

Motiva publishes "Best practices of energy-efficient construction" for the use of builders

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.

TightVent Europe newsletter issue #08 - May 2015

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.

Newsletter n°5 de l'Observatoire des Bâtiments Basse Consommation - La perméabilité à l’air du bâti et des réseaux aérauliques

This newsletter from the French "Observatoire des Bâtiments Basse Consommation" (Observatoire BBC) gives information on the airtightness of new buildings, based on a comparison between the buildings that have got the "BBC Effinergie" label  and buildings that did not get this label.

Airtightness testing requirements for Passive House and EnerPHit certification

This document provides guidance for the specific airtightness testing requirements for Passive House & EnerPHit certification, taking into account the existing differences in the calculations and methodologies when compared to the UK Building Regulations. The guide includes information on the testing protocol, the volume calculation and the test method.
