Because of the computer and electronic equipment housed within the ADP PC, the spaces require regulated temperature and humidity (usually accomplish by zoned systems), and reliable power 24 hours per day. Typical features of ADP PC space types include the list of applicable design objectives elements as outlined below. For a complete list and definitions of the design objectives within the context of whole building design, click on the titles below.
Occupancy: Occupancy Classification for ADP PC is Business Occupancy B2, with sprinkler protected construction and GSA Acoustical Class B2 for spaces with concentrations of noisy equipment.
Raised floors: Raised floors are the preferred system for distribution of critical services (power, voice, data, and HVAC) in ADP PC space types. Raised floors for ADP PC may have low-pressure high induction diffusers and be constructed of concrete filled metal pans at 24"; modules with pedestal and stringer support, with intermediate support.
Dual path service lines for power: Dual path service lines ensure a constant power supply, which is critical to the operations of ADP PC with concentrations of noisy equipment.
Redundant cooling unit: ADP PC space types are usually equipped with redundant cooling capacity to maintain the low temperature required by the computer equipment. This could consist of a split air-cooled, air-conditioning unit with 24-hour operation and setback thermostats. Acoustical transfer ducts should be installed at all acoustically rated partitions for noise control. For more information, see WBDG High-Performance HVAC.
Acoustic control: Sound baffles are provided at all acoustically rated partitions for the air supply system to control noise.
Uninterruptible Power Supply (UPS): Emergency power and uninterruptible power supply (UPS) are provided to meet all electrical requirements of the entire ADP PC (server) facility for at least 30 minutes. For more information, see WBDG Productive—Assure Reliable Systems and Spaces.
- Security protection: Implementation of an effective access control system is important in preventing unauthorized personnel from entering-and possibly sabotaging-the ADP PC. For more information, see WBDG Secure / Safe—Security for Building Occupants and Assets.
IT systems, including PCs, data storage, and data processing are energy intensive activities. However, many options can be considered to reduce energy use while also increasing efficiencies and reducing overall costs. Many organizations are developing plans to modernize data centers to realize their full potential while also reducing their impact on the environment. Best practices include utilizing the latest technologies such as virtualization technology and cloud computing. Additionally, data center design footprint can be reduced by using high-density cooling and power equipment. For areas of a data center that create a lot of heat, zone cooling devices can be deployed.
The following is a representative building program.

Relevant Codes and Standards
The following agencies and organizations have developed codes and standards affecting the design of ADP PC spaces. Note that the codes and standards are minimum requirements. Architects, engineers, and consultants should consider exceeding the applicable requirements whenever possible:
- Architectural Graphic Standards, 12th Edition by American Institute of Architects, Dennis J. Hall. New York, NY: John Wiley & Sons, Inc., 2016.
- PBS-P100 Facilities Standards for the Public Buildings Service, GSA
- GSA PBS Design Notebook for Federal Lobby Security Design
