Ventilative cooling (VC) is a way to cool or to prevent overheating in a building by means of ventilation rates higher than hygienic ventilation rates. To this end, natural (such as windows, vents, louvers) as well mechanical (extract or supply fans) ventilation devices can be used.
The Indoor Environmental Quality Global alliance (http://ieq-ga.net/) organised its first sessions at the June 2015 ASHRAE Annual conference. The sessions present a holistic approach to indoor environmental quality and give information on different societies' activities to improve the indoor environment. To access the presentations and audio files of the sessions follow the links provided:
Ventilation and air infiltration into buildings represent a substantial energy demand which can account for between 25% to over 50% of a building's total space heating (or cooling) needs. Unnecessary or excessive air change can therefore have an important impact on global energy use. On the other hand insufficient ventilation may result in poor indoor air quality, with consequential health problems, or poor thermal comfort. Designing for optimum ventilation performance is hence a vital part of building design.
Around 55 participants from 16 countries attended the international workshop on “Ventilation and Airtightness in Buildings: Voluntary and Regulatory Frameworks to Improve Quality and Compliance” which was held in Lund, Sweden on March 16-17, 2015, with AIVC as co-organiser.
A summary of the workshop and the pdfs of the presentations are freely available on the QUALICHeCK website.
AIVC is preparing a Technote on Residential Ventilation and Health. The Technote is now under review by the AIVC. Providing good indoor air quality to home occupants can have a substantial impact on occupant health and ventilation is a key tool for achieving that goal.
