During summer’s cool nights,big fans blow air through the building seven times an hour to cool the empty floors.By day,smaller fans blow two changes of air an hour through the building to circulate(流通) the air which has been in contact with the cool floors.For winter days,there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level,has cloudless skies,little dampness and rapid temperature swings(摆幅)—days as warm as 31℃ commonly drop to 14℃ at night.“You couldn’t do this in New York,with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures.It is found that the temperature of the building has generally stayed between 23℃ and 25℃,with the exception of the annual hot period just before the summer rains in October and three days in November,when a doorkeeper accidentally switched off the fans at night.And the air is fresh—far more so than in air-conditioned buildings,where up to 30% of the air is recycled.
