whether such measures generate the sav-
ings intended in the initial design and con-
struction of the separate spaces; 
‘‘(vii) best practices that encourage an 
integrated approach to designing and con-
structing separate spaces to perform at op-
timum energy efficiency in conjunction 
with the central systems of a commercial 
building; and 
‘‘(viii) any impact on employment re-
sulting from the design and construction of 
separate spaces with high-performance en-
ergy efficiency measures; and 
‘‘(B) case studies reporting economic and 
energy savings returns in the design and con-
struction of separate spaces with high-perform-
ance energy efficiency measures. 
‘‘(3) PUBLIC PARTICIPATION.—Not later than 
90 days after the date of the enactment of this sec-
tion, the Secretary shall publish a notice in the Fed-
eral Register requesting public comments regarding 
effective methods, measures, and practices for the 
design and construction of separate spaces with 
high-performance energy efficiency measures.
‘‘(4) PUBLICATION.—The Secretary shall pub-
lish the study on the website of the Department of 
Energy.’’. 
(b) CLERICAL AMENDMENT.—The table of contents 
in section 1(b) of the Energy Independence and Security 
Act of 2007 is amended by inserting after the item relat-
ing to section 423 the following new item: 
‘‘Sec. 424. Separate spaces with high-performance energy efficiency measures.’’. 
SEC. 104. TENANT STAR PROGRAM. 
(a) IN GENERAL.—Subtitle B of title IV of the En-
ergy Independence and Security Act of 2007 (42 U.S.C. 
17081 et seq.) (as amended by section 3) is amended by 
adding at the end the following: 
‘‘SEC. 425. TENANT STAR PROGRAM. 
‘‘(a) DEFINITIONS.—In this section: 
‘‘(1) HIGH-PERFORMANCE ENERGY EFFICIENCY 
MEASURE.—The term ‘high-performance energy effi-
ciency measure’ has the meaning given the term in 
section 424. 
‘‘(2) SEPARATE SPACES.—The term ‘separate 
spaces’ has the meaning given the term in section 
424. 
‘‘(b) TENANT STAR.—The Administrator of the Envi-
ronmental Protection Agency, in consultation with the 
Secretary of Energy, shall develop a voluntary program 
within the Energy Star program established by section
324A of the Energy Policy and Conservation Act (42 
U.S.C. 6294a), which may be known as Tenant Star, to 
promote energy efficiency in separate spaces leased by ten-
ants or otherwise occupied within commercial buildings. 
‘‘(c) EXPANDING SURVEY DATA.—The Secretary of 
Energy, acting through the Administrator of the Energy 
Information Administration, shall— 
‘‘(1) collect, through each Commercial Build-
ings Energy Consumption Survey of the Energy In-
formation Administration that is conducted after the 
date of enactment of this section, data on— 
‘‘(A) categories of building occupancy that 
are known to consume significant quantities of 
energy, such as occupancy by data centers, 
trading floors, and restaurants; and 
‘‘(B) other aspects of the property, build-
ing operation, or building occupancy determined 
by the Administrator of the Energy Information 
Administration, in consultation with the Admin-
istrator of the Environmental Protection Agen-
cy, to be relevant in lowering energy consump-
tion; 
‘‘(2) with respect to the first Commercial Build-
ings Energy Consumption Survey conducted after 
the date of enactment of this section, to the extent
full compliance with the requirements of paragraph 
(1) is not feasible, conduct activities to develop the 
capability to collect such data and begin to collect 
such data; and 
‘‘(3) make data collected under paragraphs (1) 
and (2) available to the public in aggregated form 
and provide such data, and any associated results, to 
the Administrator of the Environmental Protection 
Agency for use in accordance with subsection (d). 
‘‘(d) RECOGNITION OF OWNERS AND TENANTS.— 
‘‘(1) OCCUPANCY-BASED
RECOGNITION.—Not 
later than 1 year after the date on which sufficient 
data is received pursuant to subsection (c), the Ad-
ministrator of the Environmental Protection Agency 
shall, following an opportunity for public notice and 
comment— 
‘‘(A) in a manner similar to the Energy 
Star rating system for commercial buildings, 
develop policies and procedures to recognize 
tenants in commercial buildings that voluntarily 
achieve high levels of energy efficiency in sepa-
rate spaces; 
‘‘(B) establish building occupancy cat-
egories eligible for Tenant Star recognition
