§17084 Separate Spaces with High-performance Energy Efficiency Measures

Title 42 › Chapter 152— ENERGY INDEPENDENCE AND SECURITY › Subchapter III— ENERGY SAVINGS IN BUILDINGS AND INDUSTRY › Part B— High-Performance Commercial Buildings › § 17084

Summary

The Secretary of Energy, through the Assistant Secretary for Energy Efficiency and Renewable Energy, must finish a study no later than 1 year after April 30, 2015 (by April 30, 2016). The study must look at whether designing and building tenant spaces inside commercial buildings with high-performance energy efficiency measures can greatly cut energy use and how to get owners and tenants to use those measures. Two terms to know: a high-performance energy efficiency measure is a technology, product, or practice that cuts energy use and utility costs; separate spaces are areas in a commercial building leased or occupied by a tenant under a written agreement. The study must describe which measures to use, repeatable design and construction processes, policies and best practices to reduce energy for lighting, plug loads, heating, cooling, cooking, laundry, and other systems, analyses of extra costs and payback (including available incentives), models and simulations comparing energy use with and without the measures, ways to measure real energy savings, how to integrate these spaces with a building’s central systems, possible employment effects, and case studies of economic and energy results. The Secretary must publish a Federal Register notice for public comments within 90 days after April 30, 2015 (by July 29, 2015) and post the finished study on the Department of Energy website.

(a)In this section:
(1)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)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)(1)Not later than 1 year after April 30, 2015, 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)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)Not later than 90 days after April 30, 2015, 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)The Secretary shall publish the study on the website of the Department of Energy.
