Individual thermal control

Thermal comfort preferences are highly individual, and can be affected by metabolism, body type and clothing. These factors make it nearly impossible to find a temperature that will satisfy all occupants at the same time.

This feature requires spaces to vary in temperatures and gives occupants the flexibility to select a work area where they are most comfortable (termed “free addressâ€ù). It also provides personalized thermal comfort devices.

Part 1: Lobbies and Other Common Public Spaces

All lobbies and other common spaces meet the requirements set forth in ASHRAE Standard 55-2013 for thermal comfort through the use of one of the following systems:

a.93 Hydronic heating and/or cooling systems.
b.93 Electric radiant floors.
