Module 9 – Indoor Air Quality and Energy Efficiency

Module nine of the CCIAQB’s Guide for Indoor Air Quality offers recommendations for maintaining indoor air quality (IAQ) in buildings that use methods and systems to reduce energy use.

Starting with an overview of the inter-dependence of IAQ and energy efficiency, the module then lists relevant North American standards and codes. The effects of the needs for cost efficiency and occupant comfort are considered.

Strategies are given for improving a building’s energy efficiency and IAQ, which can be realized by following these steps: (1) understanding air supply and delivery concepts and systems; (2) optimizing heating, ventilation and air conditioning equipment and systems; (3) managing the building’s interior and exterior environments, such as through specific maintenance and renovation practices; (4) monitoring and evaluation of building performance, with quantified focus on energy use and air quality.

Recommendations are made to adapt existing building practices, such as IAQ profiles (described in detail in module eight) and audits, occupancy, budgeting and replacement of equipment. The module concludes with notes on communications with building occupants.
