FORI. WARD
On August 8, 2005, the Energy Policy Act of 2005 (EPAct 2005) was signed into law. Section 104 of
EPAct 2005 states that when procuring energy consuming products, all federal agencies must procure
ENERGY STAR® or FEMP-designated products unless the agency can demonstrate through written
documentation instances where:
1) An ENERGY STAR® or FEMP -designated product is not cost-effective over the life of the
product taking energy cost savings into account.
2) No ENERGY STAR® or FEMP -designated product is reasonably available that meets the
functional requirements of the agency.
In addition, Section 104 of EPAct 2005 requires the General Services Administration (GSA) and the
Defense Logistics Agency (DLA) to identify all complying products and supply exclusively those
products, unless the consumer agency specifies in writing that the product will not meet the agency's
functional requirements or will not be cost-effective. To view a full copy of EPAct 2005, visit
.
This Addendum is meant to supplement the existing four volumes of the EPA Facilities Manual with the
updated energy efficiency procurement requirements of EPAct 2005. Each section of this Addendum
contains a table that provides energy efficiency recommendations for a specific category of energy
consuming products. The recommended performance specifications found in this addendum were
gathered from the U.S. Department of Energy (DoE) Federal Energy Management Program's (FEMP)
Web site on energy efficiency requirements for 50 types of products commonly purchased by federal
agencies and the ENERGY STAR®
Web site .
Volume 2 of the EPA Facilities Manual - Architecture and Engineering Guidelines has been updated to
include references to specific sections of this Addendum where appropriate. It should be noted, however,
that not all product categories included in this Addendum are referenced in the updated version of
Volume 2. To ensure awareness of all efficiency recommendations, it is recommended that individuals
read this entire Addendum.

applications. It does not apply to high-pressure boilers used in industrial processing and cogeneration applications.
b Thermal efficiency (et), also known as "boiler efficiency" or "overall efficiency," is the boiler's energy output
divided by energy input, as defined by ANSI Z21.13. In contrast to combustion efficiency (ec), et accounts for
radiation and convection losses through the boiler's shell.

a Energy efficiency of distribution transformers is defined by NEMA's Standard Publication TP-1 as output kVA
divided by the sum of output kVA plus losses, at a specified percent load and reference temperature.
b Low voltage transformers have a primary voltage of 1200 volts or less; efficiency is measured at 35% of nameplate
load, at 75°C.
c Medium voltage transformers have a primary voltage greater than 1200 volts; efficiency is measured at 50% of
nameplate load, at 75°C for dry-type transformers and 85°C for liquid-filled.
d Liquid-filled transformers typically use oil as a combination coolant and insulating medium. Lhey are generally
higher in efficiency but are most frequently installed outside.

a The map below broadly identifies the relevant climate zones for the U.S.
b To receive these thermal performance ratings (SHGC and U-factor), windows must be certified by the National
Fenestration Rating Council (NFRC).
c SHGC, or Solar Heat Gain Coefficient, is a measure of the solar radiation admitted through a window. SHGC
ranges between 0 and 1; the lower the number, the lower the transmission of solar heat. SHGC has replaced shading
coefficient (SC) as the standard indicator of a window's shading ability. SHGC is approximately equal to the SC
multiplied by 0.87.
d U-factor is a measure of the rate of heat flow through a window. The U-factor is the inverse of the R-value, or
resistance, the common measure of insulation.
e Low SHGCs save cooling energy but increase heating energy. Therefore, lower SHGCs are most important where
cooling costs dominate.

a Roof products include single-ply membranes, built-up roof surfaces, asphalt shingles, metal roof tiles, and roof
coatings.
b Following this recommendation will provide the greatest benefit where cooling energy costs exceed heating costs.
c Solar reflectance, or albedo, is the fraction of incoming direct and diffuse solar radiation reflected by a surface.
Materials with high solar reflectance values absorb less of the sun's energy and therefore stay cooler, reducing
daytime air conditioning requirements.
d To receive these solar reflectance ratings, roof products must be tested when new and after three years of exposure,
according to ASTM E-903 and the Energy Star Roof Products Memorandum of Understanding. Initial reflectance
may decrease over time, depending on the product, due to aging, dirt, and microbial accumulation.
e For products that can be installed on both low- and high-slope roofs, "low-slope" guidelines should be followed.
