Abstract

The BRE Low Energy Office (LEO) has already demonstrated, as part of a DEn Energy Efficiency Demonstration Scheme¹, the very real opportunities for energy efficiency that can be incorporated into a building's design within normal cost limits. Five years of operating experience and monitoring of the LEO has highlighted a number of design, commissioning, and operating practices which led to unnecessary energy use and a failure to achieve design performance on a significant number of occasions. Lessons that have been learnt from the operating experience of the LEO are discussed. Because many of the problems identified in the LEO have also been found in other, more conventional, buildings, lessons learnt have an application beyond low energy designs. Over both the 1984/5 and 1985/6 heating seasons, the ‘BRESTART’ optimum start control algorithm was used, and its performance shown to be significantly better than the more conventional optimiser initially installed.
