In a warehouse type building, there are several office spaces on a mezzanine level. The offices will be occupied on an intermittent basis. All of offices are a similar size and shape, share the same external exposure, and are suitable to be on the same air conditioning zone. If the individual offices have TASK conditioning Diffusers, can each office be considered to have comfort control? The control would be a Thermal-Fuser diffusers with built-in temperature controls that operate dampers on the diffuser itself to vary the amount of airflow to the space. The airflow would be varied to meet an individual room\'s comfort set points.
The applicant is requesting confirmation regarding the use of damper controlled diffusers as thermal comfort controls for occupants in individual workstations. The proposed approach appears to satisfy the credit intent by controlling the air speed/room temperature. Per a CIR dated 3/22/2007, providing individual occupants control over one of the primary thermal comfort factors (i.e., air temperature, radiant temperature, air speed, and humidity) does satisfy the credit requirements. Applicable Internationally.
