Natural Ventilation Benefits
Building Construction Costs
Naturally ventilated buildings are less
expensive to construct than mechanically ventilated buildings. The extra
building improvement costs required to provide natural ventilation are
more than off-set reduction by a reduction in the cost for engineering
services. As a rule of thumb, naturally ventilated buildings cost about
10 - 15% less to construct than their air-conditioned equivalents.
Naturally ventilated buildings are generally
less expensive to run than air-conditioned buildings. In addition to a
significant reduction in energy consumption, maintenance costs are also
lower due to the reduced complexity of natural ventilation products when
compared to traditional mechanical systems.
Health & Productivity
Surveys have shown that people prefer a work
environment that has fresh air and natural daylight. Employees feel
better and are more alert and productive in a naturally ventilated and
climate controlled environment.
Naturally ventilated buildings have a smaller
environmental impact over buildings that strictly use mechanical climate
control. Natural ventilation reduces a building’s energy demand
(particularly electrical) and lowers the emissions of carbon dioxide
(CO2) and other byproducts that contribute to global warming.
Buildings constructed to environmentally
sensitive principles are good long-term investments as environmental
controls and legislation are likely to increase in the future.
Natural ventilation is
also used in place of mechanical systems to provide emergency smoke
ventilation in large volume spaces such as atria. Smoke ventilation
allows occupants to escape safely in the event of a fire, minimizes
costly smoke and heat damage to building contents, and increases
visibility to aid firefighting efforts.
