CHAPTER 1 INTRODUCTION
CRITERIA. Unless otherwise specified either in this document or in the
applicable UFGS, all designs shall comply with all applicable American Society of
Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) criteria and guidance.
AUTHORITY HAVING JURISDICTION. The term "AHJ" as used in the codes
and standards referenced in this UFC must mean the component office of responsibility,
i.e., U.S. Army, HQ USACE/CECW-CE; U.S. Navy, NAVFACENGCOM HQ Code
CHENG; U.S. Marine Corps, HQMC Code LFF-1; U.S. Air Force, HQ AFCESA/CES;
Defense Logistics Agency (DLA), DSS-IP; National Imagery and Mapping Agency
(NIMA), Security and Installations; and all other DOD components, Deputy Under
Secretary of Defense for Installations via the DOD Committee on Heating, Ventilating,
and Air Conditioning Engineering.
BASIC PRINCIPLES. The designer shall base all designs on the following
Select interior design conditions, including temperature, humidity, filtration,
ventilation, air changes, etc., that are suitable for the intended occupancy.
All design work shall be "sustainable" in accordance with ECB 2006-2.
Base system selections on life cycle cost effectiveness.
All DOD buildings must comply with the Energy Policy Act of 2005; whether
new construction, replacement construction, or, to the greatest extent practical,
refurbishment and system replacement.
Each design shall be as simple as possible.
Identify space necessary to access items that require maintenance, such as
filters, coils and drain pans, strainers, and chillers on the drawings in three-dimensions.
Provide systems with the features necessary for successful testing, adjusting,
and balancing, system commissioning, and for easy access for maintenance.
WAIVERS. Where a valid need exists and an alternate solution involving
sound engineering is available, designers may submit requests for a criteria waiver to
the applicable AHJ. Requests for waiver must include justification, life cycle cost
analysis, energy compliance analysis, criteria used, and other pertinent data.
REDUNDANT SYSTEMS. Generally, redundant HVAC systems are not
required. However, when a system failure would result in unusually high repair costs or
replacement of process equipment, or when activities are disrupted that are vital to
national security, the designer may submit a request for approval to the applicable
respective service proponent's office in accordance with paragraph 1-4 to provide
