Which space would MOST likely have a dedicated HVAC system?

A computer room houses sensitive electronic equipment that generates a significant and constant sensible heat load. It requires year-round cooling, precise temperature and humidity control, and often operates 24/7, independently of the main building's occupancy schedule. These unique and critical environmental requirements are fundamentally different from those of general office or public spaces, necessitating a dedicated, independent HVAC system to ensure equipment reliability and prevent overheating. This contrasts with spaces designed primarily for human comfort, which can be served by zoned central systems.

A. An office in a high rise is typically served by the building's central HVAC system as part of a larger zone, not requiring a dedicated unit.

C. A healthcare lobby's HVAC needs, while important for comfort and air quality, are generally met by a zone within the main building's system.

"HVAC Systems: Analysis and Selection

" the text discusses the need for special HVAC considerations for spaces with high internal heat gains

such as computer rooms

often requiring separate

dedicated systems to handle the unique load profile (pp. 518-519).

"Data Centers and Telecommunication Facilities." Section 21.1 states

"The need for close control of temperature and humidity

high sensible heat ratios

and high air change rates in data centers requires dedicated air-conditioning systems."

such as computer rooms

are prime candidates for separate zoning or dedicated systems to operate efficiently and effectively (p. 865).
