CHAPTER 1
INTRODUCTION
1-1. PURPOSE AND SCOPE. This document provides guidelines for design of heating,
ventilating, and air conditioning (HVAC) mechanical systems. This document delineates only
those features of HVAC design that are unique in their applications, or reflect policies that have
been established through regulations, directives, and other published media through the
Department of Defense. Unless otherwise specified, all designs will comply with the American
Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Handbooks and
Military Handbook 1008C.
1-2. APPLICABILITY. These instructions apply to all elements responsible for military
construction design.
1-3. REFERENCES. Appendix A contains a list of references used in these instructions.
1-4. BASIC PRINCIPLES. The designer will base all designs on the following basic principles:
a. Interior design conditions selected, including temperature, humidity, filtration,
ventilation, air changes, etc., will be suitable for the intended occupancy.
b. System selections will conform to the life cycle cost criteria and energy targets
specified in the Architectural and Engineering Instructions (AEI). The designer will evaluate all
energy conservation items that appear to have potential for savings, such as heat recovery for
HVAC and service water heating, economizer cycles, thermal energy storage, desiccant
dehumidification, plastic door strips for load docks, etc., and include those items in the design
that are life cycle cost effective.
c. To the maximum extent possible, designs will incorporate all practical energy sources
and design features that conserve natural resources and are environmentally friendly. This
emphasis has recently become known as "sustainable designs."
d. The design will be as simple as possible.
e. Adequate space to access items that require maintenance, such as filters, coils and
drain pans, and strainers, will be provided.
f. Systems with the features necessary for successful testing, adjusting, and balancing
and for easy access for maintenance will be provided.
1-5. WAIVERS. Where a valid need exists and an alternate solution involving sound
engineering is available, designers can submit requests for a criteria waiver to HQUSACE
(CEMP-ET), Washington, DC 20314-1000. Requests for waiver must include justification, life
cycle cost analysis, criteria used, and other pertinent data.
