Impact of over design 
The key objective of this research was to collect and disseminate information to reduce over-specification of heating, ventilation and air-conditioning systems to assist in the delivery of efficient environmental control systems that are more effective at providing better thermal environments in buildings. The project has quantified the economic and environmental penalty incurred due to over-specification.
A lessons-learned document has been produced in consultation with industry associations to assist engineers and developers in their approach to briefing and specifying HVAC systems.
