Predicting annual lighting use in daylit buildings
AbstractThe prediction of lighting use in daylit buildings is an essential stage in assessing the energy effectiveness of daylight. This paper analyses lighting control strategies and their interaction with daylight; the cumulative distribution of internal daylight illuminances is shown to be an important parameter in the prediction of annual lighting use. Methods for calculating this distribution are analysed using new long term daylight measurements in model rooms. The standard method is shown to give large errors for certain window orientations, and alternative procedures are examined which can be used as the basis for more accurate methods for predicting lighting energy consumption in daylit buildings.
