The joint 38th AIVC, 6th TightVent and 4th venticool Conference on ‘Ventilating Healthy Low-energy Buildings' was held in Nottingham, UK, 13-14 September 2017. The programme consisted of plenary sessions and 3 parallel tracks, one devoted to Ventilative Cooling in four sessions (20 papers) and 17 papers in poster sessions. Two sessions were topical, proposed by IEA EBC Annex 62, plus one discussion session. One topical session focused on case-studies [6, 18, 23-25] including houses, offices, a large space and shopping malls.
The airtightness track at the AIVC 2017 conference consisted of 23 presentations organised in 5 sessions of which 3 were topical sessions with a number of invited presentations. Most of the airtightness topics in the call for papers for the conference were represented in the papers in the airtightness track:

The industry is now focusing in system solutions and the goal is to be able to deliver complete reliable, energy efficient solutions that is understandable and easy to maintain by the normal service personal.
In order to do this the basic products have to perform exactly as they are described in the technical documentation. The documentation have to help the designer and the installer to actually build the system in the correct way without compromises from other stakeholders.

There are several methods for measuring air tightness that may result in different values and sometimes quite different uncertainties. The two main approaches trade off bias and precision errors and thus result indifferent outcomes for accuracy and repeatability. To interpret results from the two approaches, various questions need to be addressed, such as the need to measure the flow exponent, the need to make both pressurization and depressurization measurements and the role of wind in determining the accuracy and precision of the results.

Air infiltration holds a central role in building energy consumption and is associated to several building physics phenomena. Air infiltration in buildings due to wind-induced pressure is a complex process, strongly influenced by the turbulent nature of wind. This extended summary highlights the findings of a series of studies with focus on unsteady wind and its impact on air exchangesin buildings. The focus is on wind gustiness and its relation to air infiltration under natural conditions.
