Standard Level Features and Finishes
Building Envelope. The baseline for exterior facade materials is stone, brick, or similar
material for U.S. courthouses. See window requirements in PBS-PQ100.1. As part of the
standard special space provisions, provide vehicular sallyport doors to meet USMS
specifications.
Changes in Building Envelope to Meet Energy Guidelines. Due to the energy load
requirements of U.S. Court facilities, GSA will use the alternative design processes of
ASHRAE 90 to meet Federal energy guidelines for overall building energy usage. Increases
in building system energy resistance will be used to compensate for higher load requirements
resulting from court functions.
GSA will establish total building energy usage according to calculations using factors
contained in PBS-PQ100.1. To demonstrate the same total energy usage, a new calculation
will be done incorporating factors for energy reduction strategies to offset increased lighting,
cooling, and heating energy loads.
Engineering System Requirements
Design of Environmental Conditions Within "Special" Spaces. GSA will provide HVAC
systems designed to cool courtrooms, judge's chamber suites, and jury deliberation suites to
o
o
24 C (75 F) with full load in summertime. The actual operating will be set for the locally
determined comfort level. In addition, the courtroom will be connected to a building
automation system so that the room can be precooled prior to scheduled occupancy down to
o
o
21 C (70 F). Jury deliberation rooms, courtrooms, and judges' chambers will be treated as
"conference rooms" (i.e. as an independent zone with separate controls). The courtroom,
judge's chamber suite, and the jury deliberation room, which comprise a single "court set,"
shall be arranged such that the air side of the systems can be run after hours without turning
on a majority of the building system. GSA may use zoning controls to provide this level of
service in the event an AHU is designed to serve two or three court sets. GSA will include
winter humidification in areas and regions specified in PBS-PQ100.1. Special controls for
summertime dehumidification will not be included since modern HVAC systems are designed
to keep relative humidity within acceptable ranges. The USMS area will have 24-hour
service, with a separate AHU. Please refer to the description of the area-of-refuge contained
in this document.
