Abstract

Climatic data from three well separated European locations have been used to simulate and compare the performances of a number of different window systems. Among the systems compared are windows incorporating semi- reflected and selective films, with and without management. The performance of each window system is evaluated by calculating the energy gain or loss on an hourly basis throughout the year and summing over the heating season. This is done for N, S, E, and W facing windows. The results are used to estimate the relative merits of the different window types, both in terms of energy balance and cost effectiveness. Particular attention has been given to managed, semi- reflecting roller blinds which, when applied to single glazing, should offer an attractive low cost retrofit measure. The problem of summer overheating which can occur with some South facing windows is also discussed and the possibility of reducing this with semi-reflecting blinds is pointed out. Indications are given for the way in which film characteristics should be modified in order to improve performance.
