both high indoor air
quality and energy efficiency requires an integrated design
approach.
There is a movement in the commercial real estate industry to pay
more attention to the issue of indoor air quality (IAQ) throughout
the design and construction stages of a building's life.
The "Green Design" movement also places emphasis on IAQ. This
Design Brief defines indoor air quality, discusses ventilation as a
method of maintaining high IAQ, and introduces demand controlled
ventilation (DCV).
With increasing concerns about electricity demand in California,
2001 Title 24 Standards require that DCV strategies be employed in
high-density areas (occupant density of more than one person per 10
square feet).
The brief ends with a discussion of seven ways to ensure that a
building's indoor air quality strategy is both energy-efficient and
health-inducing.
The first edition of this design brief was prepared for Energy
Design Resources in 2003. Between January and April of 2010, an
engineering review of this document was conducted to update
passages affected by recent changes in the California Building
Energy Efficiency Standards (Title 24 2008). The original content
creator was not actively involved in this engineering review, and
therefore is not responsible for the updates to the affected
passages.
