A proposed American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guideline, currently out for public comment, would provide guidance on achieving good indoor environments by considering the interactions of air quality and thermal conditions, as well as lighting and acoustics.

ASHRAE Guideline 10P, Interactions Affecting the Achievement of Acceptable Indoor Environments, calls attention to many interactions that designers might not have recognized or understood previously. The guideline will remain open for public comment until May 24.

The guideline is intended to help users understand and use existing documents that deal with indoor environments, including the ASHRAE standards related to ventilation, indoor-air quality, and thermal conditions with a more complete understanding of the impacts of the indoor environment on occupants.

The draft of Guideline 10P is available for comment only during its public-review period. To read the guideline or to comment, visit www.ashrae.org/publicreviews.
