Reviews the results of IRC research on some key factors that influence the performance of a ventilation system in large buildings. It discusses the effects of these factors and provides guidelines for operating the system efficiently. Improving the airtightness of older buildings will reduce air leakage and cold drafts, and help reduce energy use by improving the performance of ventilation systems.
Performance checks on ventilation systems carried out by the Swedish Board of Housing Building and Planning showed that approved systems (37%) are divided into blocks of flats (25%), office buildings (43%), schools (37%), day care centres (51%) and health
General Dynamics Armament Systems was looking for a way to improve the performance of the ventilation system in their Lakeside Avenue industrial plant in Burlington, Vermont. By utilising adjustable speed drives (ASDs) and making other modifications to the system, they were able to improve the plant's overall operating efficiency, reduce costs, and improve the work environment and worker health and safety. This Motor Challenge Showcase Demonstration Project has resulted in annual savings of more than USD 68, 000, with a payback of just under one and a half years.
