Air movement can cool a person indoors in a similar manner as
lowering the temperature, but needs only a tiny fraction of the
energy. New fans of 1-8 watts producing 0.6 to 1 m/s (1.5 to 2
mph) air movement near each of a building's occupants can offset
a 6ºF (3K) increase in indoor air temperature, while actually
improving the occupant's comfort and perceived air quality.
Increasing the indoor temperature reduces a building's total HVAC
(heating, ventilating, and air conditioning) energy about 5% per
degree F, or 10% per degree C, and even more in climate zones
where the indoor temperature allows natural ventilation or
evaporative cooling systems to be used instead of
compressor-based cooling. Across US climates, air movement
permits year-round HVAC energy reductions averaging 1000 watts
per occupant. The energy reductions possible from improved fan
use exceeds that of many other current technological improvement
to buildings. The opportunities for new design approaches and new
fan products are considerable.
