A regional distributor of BMW's typical of many car showrooms it is a
building constructed with predominantly glazed walls.
'Whilst the glazing is excellent for displaying cars
it does lead to very high levels of solar heat gain which means the temperature in the
showroom could reach in excess of 35 degrees centigrade'
Evaporative cooling was chosen to cool the
showroom because of its simplicity, low cost and environmental advantages over
refrigeration based air conditioning.
The roof of the showroom is single skin
corrugated metal with a layer of insulation and a felt final external covering. A down
discharge evaporative cooler was fitted to the roof using an up-stand, which was supported
by additional steelwork fitted to the metal and felt layer which was in tern weather
proofed to the up-stand. The cooler then feeds into an eight way plenum achieving
approximately 12 air changes per hour for the showroom. |
