Theory to Application: A Virtual Air Barrier / Dynamic Buffer Zone Application to a Large Office Building
The VAB/DBZ approach protects your heritage building envelope from higher moisture loads during renovation. Join this webinar to gain an understanding of the VAB/DBZ approach, through a case study of the C. W. Sherwood Co. Ltd. building in Saskatchewan.
Historic buildings in Canada are often 100 years old or more. Some of these buildings continue to provide occupancy but the indoor conditions are often not up to modern expectations. To be acceptable these buildings need to support an adequate indoor temperature, relative humidity, indoor air quality as well as controlled building pressure. They are most often upgraded mechanically with new ventilation, heating cooling and winter humidification. These upgrades create new building envelope loads with risks of wall and roof condensation. These new loads can and do damage expensive restoration in very short order.
