Whole House Low Energy Passive Ventilation System
WHoLE PVS Seminar
20 September 2004
Cambridge University
This seminar will look at the issues surrounding a recent Partners in Innovation (PII) project involving the Building Research Establishment (BRE) and a number of industry partners. These partners include Cambridge University and Cambridge Architectural Research (CAR) and the project concentrated on the implementation of a whole house low energy passive ventilation system.The WHOLE-PVS system addresses the mismatch between the conflicting requirements of health and energy use by providing an engineered level of air flow. The system employs a new approach in which passive stack ventilation and 'supply air' windows are used. These windows allow incoming fresh air to pass between the panes of glass. If the airflow is at the right speed, and the gap between the panes is correct, smooth air flow reduces the heat loss across the window. The heat lost from the room is entrained in the air path and returned to the room.
'Passive stack' ventilation uses the buoyancy of a column of warm air in vertical air ducts to remove contaminated air from the kitchens and bathrooms. By employing passive stack vents as the power source to draw air through the 'supply air' windows, the whole system can be entirely passive.
Speakers: BRE, Cambridge University, CAR and industry partners.
