[INSERT LOCATION OF FACILITY]
6.5.1.2 ENERGY CONSERVATION AND BUILDING ENVELOPE:
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 Conservation Voluntary Performance
Standards for Commercial and Multi-Family High Rise Residential Buildings; Mandatory for New Federal
Buildings." A copy can be requested from VA. 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:
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 to this
solicitation.
The building thermal envelope for new VA health care facilities shall be energy efficient to minimize the
heat gain and loss due to conduction and solar radiation. The building envelope shall minimize the air
leakage to and from the occupied spaces and shall also ensure condensation control.
Recommended "U" Values: The following represents the recommended "U" values of walls, roof and glass,
and the Shading Coefficients (SCs) of glass for new construction. These values should be used to meet
the overall Uo factor, for the building gross wall area, defined under the next paragraph.
Degree-Days
Wall "U"
Glass "U"/SC
Roof "U"
Floor "U"
3000 & Below
0.12
0.57/0.40
0.05
0.05
3001 to 5000
0.10
0.40/0.50
0.05
0.10
5001 & Above
0.07
0.35/0.33
0.03
0.08
The degree-days are based on the heating season when outdoor temperatures are below 65 degrees F, in
accordance with ASHRAE Handbooks-Fundamentals and Systems.
The SCs of the glass windows are based on the intrinsic property of the glass material only, that is, without
any assistance from the external shading devices, such as, venetian blinds and/or curtains.
Insulating glass with lower "U" value might be necessary to prevent condensation while maintaining the
required 30 percent Relative Humidity (RH) in perimeter spaces with 25 degrees F outdoor design
temperature and below.
2
The "U" values are expressed as BTUH/Hr-Ft .
F
The "U" values are for floors of heated spaces over unheated areas, such as sub-basements (pipe
basements), garages, crawl spaces, etc. The requirements of insulation for the slabs-on-grade for the
heated spaces are shown under perimeter insulation.
