The author maintains that the testing methodology of ASHRAE 62-1989R, mired in a swamp of controversy and "continuous maintenance," may need some fresh air.
The need for energy efficient buildings is outlined, and the principal issues relating to commercial developments are discussed. The importance of natural cooling is highlighted, and the associated principle are examined. Some ways in which this can be achieved in conventional steel framed construction are presented. The suggestions include passive systems which rely simply on exposing sufficient thermal capacity of the building fabric, and active systems which provide greater control and improved performance. They represent an application of technology for sustainable development.
