The project team is providing thermostat controls at all shared multi-occupant spaces in our project and the client would like to provide staff with desktop air purifier units that provide individual occupant control of air speed. The personal air purifier units have the following features: three speeds control, 70
The project team is correct in stating that individual control over one of the primary thermal comfort factors (i.e. air temperature, radiant temperature, air speed, and humidity) will satisfy the controllability requirement of this credit. The personal air purifiers described above will provide occupants individual control over air speed. However, the intent of this credit is to make thermal comfort controllability an integral part of the building design for occupants. Therefore, unless the fans/air-purifiers are hard-wired in the building system, they will not satisfy the requirement of this credit. Similarly, plug-in desktop fans will not satisfy the requirement of this credit which deals with providing thermal comfort control as an integral part of the building design. Note that for the purposes of this credit, the fan component of the device is of importance. The air purification feature of the device does not address thermal comfort and thus will not add to the thermal comfort controllability of the device. Applicable Internationally.
