SEPARATE SPACES WITH HIGH-PERFORMANCE ENERGY EFFICIENCY MEASURES.

SEC. 424. [42 U.S.C. 17084] SEPARATE SPACES WITH HIGH-PERFORMANCE ENERGY EFFICIENCY MEASURES. (a) Definitions.—In this section: (1) High-performance energy efficiency measure.—The term “high-performance energy efficiency measure” means a technology, product, or practice that will result in substantial operational cost savings by reducing energy consumption and utility costs. (2) Separate spaces.—The term “separate spaces” means areas within a commercial building that are leased or otherwise occupied by a tenant or other occupant for a period of time pursuant to the terms of a written agreement. (b) Study.— (1) In general.—Not later than 1 year after the date of enactment of this section, the Secretary, acting through the Assistant Secretary of Energy Efficiency and Renewable Energy, shall complete a study on the feasibility of— (A) significantly improving energy efficiency in commercial buildings through the design and construction, by owners and tenants, of separate spaces with high-performance energy efficiency measures; and (B) encouraging owners and tenants to implement high-performance energy efficiency measures in separate spaces. (2) Scope.—The study shall, at a minimum, include— (A) descriptions of— (i) high-performance energy efficiency measures that should be considered as part of the initial design and construction of separate spaces; (ii) processes that owners, tenants, architects, and engineers may replicate when designing and constructing separate spaces with high-performance energy efficiency measures; (iii) policies and best practices to achieve reductions in energy intensities for lighting, plug loads, heating, cooling, cooking, laundry, and other systems to satisfy the needs of the commercial building tenant; (iv) return on investment and payback analyses of the incremental cost and projected energy savings of the proposed set of high-performance energy efficiency measures, including consideration of available incentives; (v) models and simulation methods that predict the quantity of energy used by separate spaces with high-performance energy efficiency measures and that compare that predicted quantity to the quantity of energy used by separate spaces without high-performance energy efficiency measures but that otherwise comply with applicable building code requirements; (vi) measurement and verification platforms demonstrating actual energy use of high-performance energy efficiency measures installed in separate spaces, and whether such measures generate the savings intended in the initial design and construction of the separate spaces; (vii) best practices that encourage an integrated approach to designing and constructing separate spaces to perform at optimum energy efficiency in conjunction with the central systems of a commercial building; and (viii) any impact on employment resulting from the design and construction of separate spaces with high-performance energy efficiency measures; and (B) case studies reporting economic and energy savings returns in the design and construction of separate spaces with high-performance energy efficiency measures. (3) Public participation.—Not later than 90 days after the date of the enactment of this section, the Secretary shall publish a notice in the Federal 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 publish the study on the website of the Department of Energy.
