Building Environmental Assessment Schemes for Rating of IAQ in Sustainable Buildings.

This paper provides a review of the building environmental schemes for rating of indoor air quality which could have an important impact on health and wellbeing of occupants in sustainable homes and buildings. The majority of the building environmental assessment schemes introduced in different countries of the world are based on the BREEAM and LEED model. BREEAM has a major emphasis on energy efficiency whereas ‘‘Indoor Environmental Quality’’ and ‘‘Health and Wellbeing’’ are the most central issues for LEED. The criteria included in BREEAM, LEED and HK BEAM rating systems for assessment of indoor air quality (IAQ) are illustrated. There should be an IAQ management plan for any housing or building development, which should include a certification of the IAQ of the living spaces prior to occupancy and that low emitting materials should be used in the new build. There should also be an ongoing maintenance of the ventilation and HVAC system for the building and this should be part of an IAQ management plan for the building operation and maintenance.
