Abstract
Earth heat exchange (EHX) through buried
horizontal air ducts (EHXair-hor)
can be an effective passive/hybrid system to reduce heating and cooling
loads in temperate climate zones. This paper shows the results of field
testing, by the authors, of a buried pipe system for a single family
dwelling and the design development of a large EHXair-hor
system for a High School building. The monitoring plan for the latter is
also described. Considerations
on critical aspects, such as the terrain warming effect of EHXair-hor systems are also outlined.
Key words: ground heat
exchange, buried pipes, field study, passive cooling.
