The aim of the research was to demonstrate the benefits of large areas of south facing, high performance glazing in a domestic situation in a Northern climate. The single storey houses were designed to maximise the area of south facing glazing, whilst retaining occupant privacy, but also enabling the houses to be built on a north-south road grid. The glazing system used was an innovative arrangement of low emissivity coated glass, sealed argon filled triple glazing, integral blinds and timber frames. U-value was measured at 0.9 W/m2K. The houses were highly insulated, well sealed with heat recovery ventilation, with auxiliary heating supplied by a very efficient wet central heating system. Performance was found to be highly dependent on occupant behaviour patterns, which almost obscured the differences between the double and high performance glazing designs. The high performance glazing was also found to suffer from low solar transmission (about 40%) due to the four layers of glass and two low emissivity coatings. The emissivity of the low-e coatings was higher than expected and the aluminium spacers further degraded performance. Occupant satisfaction with the overall house design was found to be high when assessed by questionnaire.
