1.6 ENGINEERING ECONOMIC ANALYSIS
To comply with Public Law 95-619, engineering economic analysis shall
be performed, in accordance with the procedure outlined by the
Department of Energy (DOE) in National Institute of Standards and
Technology (NIST) Handbook 135 (Life Cycle Cost Federal Energy
Management Program), to select the most cost effective HVAC system for
the application. The additional features of the analysis are:
A. For comparison of systems, a 20 year life cycle shall be assumed.
B. The analysis may be performed by means of available public domain
programs, such as, "TRACE", "E-CUBE", and CARRIER E20-II, etc.
C. For specific VA requirements relative to the system configuration and
limitations, see Article 3.
D. Other relevant features are: 7% discount factor for future cost and
no taxes or insurance in computing annual owning cost.
1.7 ENERGY CONSERVATION CERTIFICATE REQUIREMENTS
Energy conservation shall be emphasized in all aspects of building
design. The buildings must meet the requirements of DOE regulations,
10 CFR Part 435, "Energy Conservations Voluntary Performance Standards
for Commercial and Multi-Family High Rise Residential Buildings;
Mandatory for New Federal Buildings." A copy can be obtained from the
VA on request. These standards are mandatory for all new VA
facilities. To demonstrate compliance with these regulations, it will
be necessary for the A/E to provide the following information:
A. CERTIFICATE OF COMPLIANCE: The A/E shall certify that the Building is
designed to be in compliance with the applicable provisions outlined
in the DOE regulations identified above. A blank copy of the required
certificate is attached. See Article 10.
B. ESTIMATED ENERGY CONSUMPTION: With the final design submission
(construction documents - or working drawings - phase), the A/E shall
estimate the energy consumption of the proposed new building(s) and
provide a value in Watts per gross square meter per year (British
Thermal Units (BTU) per gross square foot (GSF) for each building. To
accomplish this task:
1. The building(s) operation shall be simulated on the basis of the
actual configurations of the mechanical/electrical systems
designed to save them.
2. A public domain computer program shall be used to calculate the
estimated energy consumption.
1.8 NTERDISCIPLINE COORDINATION
HVAC design must be coordinated with all other disciplines, such as,
Architectural, Structural, Electrical, Plumbing, and Site Planning.
