18-19 September 2018, Conference, Juan-les-Pins, 39th AIVC conference

The 39th AIVC conference: "Smart ventilation for buildings" will be held on 18 and 19 September 2018 in Juan-les-Pins, France. It will also be the 7th TightVent conference and the 5th venticool conference.

Conference Scope

Energy and climate goals have been shaping many countries’ policy and legislative agendas in the EU and beyond in the past decade. 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.

On the contribution of steady wind to uncertainties in building pressurisation tests

This paper analyses the contribution of a steady wind to the uncertainties in building pressurisation tests, using the approach developed in another paper (Carrié and Leprince, 2016). The uncertainty due to wind is compared to the uncertainties due to other sources of uncertainty (bias, precision and deviation of flow exponent).
The main results of this study are:

Full-scale experimental study of ceiling turbulent air jets in mechanically ventilated rooms

Experimental investigation of ceiling circular grille air jets was conducted in a full-scale entirely controlled test room (6.2 x 3.1 x 2.5 m). Our case study is based on a realistic ventilation system configuration: it introduces a plenum box, two air exhausts, as well as a vertical wall near the air inlet. Analyses were initially concentrated at the air inlet region since it is the zone having strong gradients. Deviations concerning the trajectory of the actual jet were observed with respect to the theoretical jet.

Towards the definition of an indoor air quality index for residential buildings based on long-and short-term exposure limit values

In the Framework of the IEA EBC Annex68 Subtask 1 working subject, we aimed at defining an indoor air quality index for residential buildings based on long- and short-term exposure limit values. This paper compares 8 indoor air quality indices (IEI, LHVP, CLIM2000, BILGA, GAPI, IEI Taiwan, QUAD-BBC and DALY) by using the French IAQ Observatory database that includes pollutant concentration measurements performed in 567 dwellings between 2003 and 2005. This comparison allows to make a relevant analysis of each index and determines their pros and cons i.e.

From EN 779 to ISO 16890: a new worldwide reference test method for general ventilation filters

For testing of general ventilation filters, a completely new standard is now available and is going to replace EN 779 (2012) since the parts 1 to 4 of ISO 16890 (2017) have been adopted in August 2016 and published in 2017 at both international and European levels. With this new standard, the fractional efficiency of the new and the conditioned (24 hours to isopropanol vapour) filters is measured between 0.3 and 10 μm.

About 1,000 ductwork airtightness measurements performed in new French buildings: database creation and first analyses

In France, the current regulation on the energy performance of buildings (RT 2012) does not require ductwork airtightness measurement when the default-value is used in the regulatory EP-calculation. Thus, measurements are only mandated when a specific airtightness level is used in EP-calculations or required by a voluntary certification scheme. In such case, measurements have to be performed according to a national scheme regarding ductwork airtightness measurement.
