In the temperate climate, the consistency of bioclimatic designs for heating and cooling is essential. However, the traditional Japanese houses which have excellent cooling techniques often disclose their poor thermal performance in the winter time. Since Jong it has been said that they sacrificed the heating performance in return for the cooling performance, as a result of their choice in the time when the consistency was technically impossible.
Hampshire County Council has a deservedly high reputation for imaginative, low energy educational buildings. In 1995, County Architect Sir Colin Stansfield-Smith worked his magic for Portsmouth University. Has the mixed mode solution for the Portland Building done the trick?
The BRE has tested different methods for heating low energy houses. Did a warm air system with mechanical ventilation and heat recovery beat the more conventional wet radiators and electric panels?
