Parking garages require ventilation because the exhaust fumes produced by the vehicles have to be discharged. This can be achieved with a mechanical or a natural ventilation system. A natural ventilation system has several important advantages compared with a mechanical system. As a rule natural ventilation systems arc simpler, cheaper and have fewer breakdowns, furthermore a natural system requires less maintenance and uses no energy (for air transfer).
One of the most important projects of the 1990s has just been completed - the naturally ventilated School of Engineering at De Montfort University in Leicester. Roderic Bunn reveals how it could influence a new breed of environmentally sensitive buildings.
New research shows that replacing low efficiency window air conditioners with high-efficiency units can produce measurable savings and can be cost-effective in homes with high air conditioning electricity consumption.
Gives a personal assessment of the most important energy utilisation techniques. Describes low-energy buildings, the building fabric, ventilation, energy saving heating systems, including oil heating, gas heating, wood-firing systems, heat pumps, co-generation, solar systems (active), heat emission and heat control; and waterheating.
