Abstract

This paper presents measured results from a 'superglazed' and an otherwise identical double-glazed house, and compares the monitored data with predictions from a dynamic hour-by-hour simulation model (SERI-RES) and a degree-day model (DESIGNER). The 'superglazing' has a measured U-value of 0.8 ± 0.1 W m^-2 K^-1, and the double glazing of 2.8 ± 0.1 W m^-2 K^-1. Five superglazed and three double-glazed houses at Milton Keynes were monitored for two years. SERI-RES was driven with weather data measured on site, and the observed schedules of casual gains. Agreement between measurements and predictions is very good over the whole heating season and fairly good on a month-by-month basis. Internal temperatures are underpredicted, and solar gains and building heat loss overpredieted, during the summer. In DESIGNER the weather conditions are represented as monitored degree-days. The annual consumption figures compare well with those measured; but there is little scope for examining the performance of each building component in relationship to energy use.
