For example, in the building energy efficiency survey of non-domestic stock for England and Wales in 2014-15, 1 the energy consumed by fans was estimated at more than 6GWh per year. This CPD will explore the relevance of the SFP, and consider some aspects of how the fan selection and location will influence its value.įan power is a significant consumer of energy in buildings. It provides an important measure of the performance of fan-powered systems that impacts a building’s energy costs and carbon impact for the whole life of the installation. Establishing the specific fan power (SFP) for ventilation (and air conditioning) systems is not simply a mundane calculation to evidence compliance with regulations and standards.
