CONFLICTS IN CRITERIA. If any conflicts arise between the service's
safety criteria and ASHRAE 15, the most stringent requirement shall prevail. If a facility
is located off of military owned sites, where local jurisdictional authority has control and
code requirements that are more stringent than those herein, the local jurisdictional
authority will prevail.

SUSTAINABLE DESIGN. It is the policy of the tri-services to incorporate
sustainability concepts in the design of all facilities and infrastructure projects to the
fullest extent possible, consistent with budget constraints and customer requirements.
This policy applies to renovations and alteration projects as well as new construction;
applies to projects regardless of funding source or amount; applies to projects for all
customers; and applies to design associated with all procurement methods, including
design/build. For further information, see NAVFAC Planning and Design policy

DEFINITIONS
Azeotropic A precise refrigerant mixture or blend of substances that has
properties differing from either of the two constituents.
Design-Build Contractor furnishes a designed and constructed facility,
usually from a performance specification.
Direct Expansion System - A refrigerant system that has the refrigerant
entering an expansion valve and only vapor leaves the evaporator.
Glide The absolute value of the difference between the starting and
ending temperatures of a phase change process by a refrigerant.
Halocarbon Refrigerant that is a hydrocarbon derivative that contain one
present.
Liquid Recycle System
A refrigerant system that has liquid
refrigerant in the evaporator in amounts larger than can be evaporated and obtains
higher efficiencies due to higher heat transfer of wetted surfaces.
Plan and Specify Engineering firm furnishes a design, then the design is
competitively bid.
