((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 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 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.April 30, 20152015-04-30
((4)) ** Publication** The Secretary shall publish the study on the website of the Department of Energy.
