This presentation will cover the key lessons learned from post-occupancy evaluation of the ventilation strategies in several new-build dwellings in the UK.
Esfand Burman
This report reviews the activities of the AIVC during its first twenty years of operation. It identifies key projects and addresses them in the context of research activities and associated issues of the time.
Martin Liddament
The modelling of air flows to investigate indoor air quality and energy issues has been a topic at the AIVC for all of its 40 years.
Iain Walker
The purpose of this summary is to review Air Infiltration and Ventilation Centre activities, as reflected in its publications, related to indoor carbon dioxide over the 40 years that have transpired since its creation.
Andrew Persily
This extended summary is a part of a more extensive summary (technote to be published) that compiles a number of AIVC publications that deal with ventilation and health in relation to moisture in air, and the development over time.
Paula Wahlgren
Japan is characterized by high humidity in summer and low humidity in winter. Therefore, summer is in a climatic condition where mold is easy to grow, and in fact, mold damage is occurring.

People spend 70% -90% of their time indoors. Indoor air quality and human body’s health have a close relationship. With the advance of society, user comfort requirements for thermal environment are rising.
Fangyuan Zhang, Yuji Ryu
A demonstration house was previously built and commissioned in Iqaluit, Nunavut, Canada.

The Arctic environment is challenging for housing ventilation and heating systems. Energy consumption and demand for space heating for northern remote community residential buildings are very high.
Boualem Ouazia, Chantal Arsenault, Yunyi Li, Michael Brown, Gerald Kolsteren, Christopher Chisholm
The work presented in this paper investigates frosting problem on high efficient air to air counter flow heat exchanger. The presented investigation consists of two main activities.  
Michal Pomianowski, Rasmus Lund Jensen, Dzhanan Osman Metin, Nils Kristian Kure Rasmussen and Diana State
Heat recovery ventilation (HRV) is one of the usual techniques (next to demand controlled) to reduce the energy impact of ventilation in buildings.
Sébastien Pecceu, Samuel Caillou
Various studies demonstrate a significant impact of ductwork leakage on the fan power consumption of ventilation systems.
Valérie Leprince, Marcus Lightfoot, Jelmer de Jong
Over the last few decades, there is a clear target for reducing energy needs in the building sector.
