Enlightenment Through Modelling and Monitoring: UK Domestic Lighting
Jane Palmer
Environmental Change Unit, UK
Abstract
Domestic lighting electricity consumption figures are often based on rough estimates or on the Œresidual? electricity after other end uses have been accounted for. There is a danger that this leads to inaccurate estimates of lighting consumption and so fails to highlight the importance of this sector in terms of potential energy savings.
As part of the DECADE (Domestic equipment and carbon dioxide emissions) project, the figures for UK domestic lighting electricity consumption have been revised to almost double previous estimates on the basis of a lighting stock model. These revisions were then confirmed through three studies which have actually monitored lighting consumption in the UK, thus illustrating the importance of such studies in determining accurate figures for this sector.
