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: Free Address

Projects over 200 m² [2150 ft²] have the following free address requirement:

a) The building provides a thermal gradient of at least 3 °C [5 °F] across open office spaces, between rooms or between floors.
b) All open office spaces with occupants performing tasks that require similar workstations allow for at least 50% free address to allow occupants to select a work space with a desired temperature.
Part 2: Personal Thermal Comfort Devices

The following condition is met in spaces with 10 or more occupants in the same heating or cooling zone:

a) Occupants have access to personal thermal comfort devices such as fans (excluding space heaters).
