The 39th AIVC conference: "Smart ventilation for buildings" was held on 18 and 19 September 2018 in Juan-les-Pins, France. It was also 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.
Better performing buildings must ensure an acceptable Indoor Environmental Quality (IEQ), by providing higher Indoor Air Quality (IAQ) and comfort levels for their occupants. Building ventilation entails both challenges and opportunities to achieve this goal.
A specific challenge lies in providing smart ventilation—i.e., the desired IAQ benefits while minimising energy use, utility bills and other non-IAQ costs (such as thermal discomfort and noise). Building ventilation should also help prevent overheating with little energy use. Nevertheless, the correct functioning of ventilation systems, whether natural, mechanical or hybrid should not be compromised by excessive infiltration and uncontrolled airflows. While experience shows that these hurdles are difficult to pass, they also represent fantastic opportunities for design, method, and product development.
This was the context defining the core theme of the joint 39th AIVC, 7th TightVent and 5th venticool Conference as “Smart ventilation for buildings”.
The event placed its focus on:
- Smart ventilation, IAQ and health relationships
- Ventilation and airtightness
- Ventilative cooling – Resilient cooling
Conference concept
The conference consisted of a mixture of:
- Well‐prepared and structured sessions focused on the conference topics;
- Presentations on invitation;
- Presentations arising from the call for papers.
