We are pleased to announce that the AIVC 2019 Conference “From Energy crisis to sustainable indoor climate – 40 years of AIVC" is now accepting abstracts & proposals for topical sessions. The Conference will be held during 15-16 October, 2019 at ‘Het Pand’, the congress centre of Ghent University in Ghent, Belgium.
The conference programme will include well‐prepared and structured sessions focused on the conference topics, invited speakers, long and short oral presentations arising from the call, as well as 90 seconds industry presentations.

The 40th AIVC conference was held on 15 and 16 October 2019 in Ghent, Belgium. It was also the 8th TightVent conference and the 6th venticool conference.
Conference Scope
In the past 40 years, since the first oil crisis in the seventies, energy and climate goals have been shaping many countries´ policy and legislative agendas. The building sector plays a crucial role in achieving these goals, considering the energy use attributed to buildings and its huge potential for improved energy performance.

The market uptake of BIM (Building Information Modelling) is rapidly growing in nearly all European countries and one can assume that this trend will continue and even accelerate in the coming years.
In practice, there was until recently in most countries little to no attention for BIM as a support tool for the regulatory assessment of the energy performance of buildings. A smart use of BIM can be a win-win situation for both areas, whereby there surely are still several bottlenecks and challenges ahead of us.

In order to reduce the energy use of buildings, policy makers impose stringent requirements with regard to energy performance of new buildings and renovated buildings, and the use of renewable resources. Most compliance checks and labelling of the energy performances of buildings are done in the design phase by calculating the theoretical energy use. But, despite regulation and policy enforcements, monitoring of actual energy performances reveals in many cases a significant gap with theoretically designed targets.

This paper discusses two particular points of the buildings airtightness measurement method (ISO 9972) in relation with the calculation of the combined standard uncertainty: (1) the zero-flow pressure difference and (2) the weighted line of organic correlation.

Thermal comfort is an important aspect of the building design and indoor climate control as modern man spends most of the day indoors. Conventional indoor climate design and control approaches are based on static thermal comfort models that views the building occupants as passive recipients of their thermal environment. Assuming that people have relatively constant range of biological comfort requirements, and that the indoor environmental variables should be controlled to conform to that constant range.

When considering the performance of HRV systems, the discussion is generally focusing on the reported effectiveness of the air-to-air heat exchanger. Although some excellent presentations at the AIVC conference in the past have dealt with uncertainties related to the test of that effectiveness, the fact that the heat recovered by the HRV unit might not be useful in an intermittently heated dwelling without room-by-room based demand control is usually not considered. Therefore, the ‘use-factor’ for the recovered heat is quantified in this paper.

Over the last decade, TVOC sensors have been touted as an interesting alternative to CO2 and RH sensors in DCV systems. Nevertheless, there is little evidence on the nature and the profile of TVOC concentrations in modern dwellings.

In the context of the PREVENT project, preparing a possible revision of the Belgian residential ventilation standard, the way of expressing ventilation requirements, among others in terms of ventilation flow rates, needs to be investigated. The aim of this paper is to propose and compare ways of expression of the ventilation requirements in terms of flow rates with respect to their robustness across dwellings.
