Executive Order 13514 is an executive order titled ''Federal Leadership in Environmental, Energy, and Economic Performance'' that U.S. President Barack Obama issued on October 5, 2009. EO 13514 was revoked by EO 13693, titled ''Planning for Federal Sustainability in the Next Decade'', also issued by Obama March 19, 2015.〔https://sftool.gov/learn/annotation/416/executive-order-13514-federal-leadership-environmental-energy-economic-performance-archived〕 This executive order mandates that at least 15 percent of existing federal buildings and leases meet Energy Efficiency Guiding Principles by 2015, and that annual progress be made toward 100 percent conformance of all federal buildings, with a goal of 100% of all new federal buildings achieving zero-net-energy by 2030. The U.S. government is the largest consumer of energy in America. It has roughly 500,000 buildings, and most of these buildings are energy-inefficient. Fifteen percent of 500,000 buildings is 75,000 buildings. The executive order states that "the Federal Government must lead by example ... increase energy efficiency; measure, report, and reduce their greenhouse gas emissions from direct and indirect activities ... design, construct, maintain, and operate high performance sustainable buildings in sustainable locations; strengthen the vitality and livability of the communities in which Federal facilities are located; and inform Federal employees about and involve them in the achievement of these goals." "Zero-net-energy building" is defined in Executive Order 13514 as "a building that is designed, constructed, and operated to require a greatly reduced quantity of energy to operate, meet the balance of energy needs from sources of energy that do not produce greenhouse gases, and therefore result in no net emissions of greenhouse gases and be economically viable". ==Details and timeline== The timeline and means for achieving the stated goal of zero-net-energy federal buildings can be summarized as follows: * Green roofs are explicitly recommended for government buildings. * Zero-net-energy goals are to be incorporated into the process of buying or leasing new government properties. * As of 2020, all planning for new Federal buildings requires design specifications that achieve Zero-Net-Energy use by 2030. * Large government buildings have to start showing progress by 2015. More specifically, at least 15 percent of any agency's existing buildings and building leases above 5,000 gross square feet must conform to Zero-Net-Energy by Fiscal Year 2015. Ongoing improvement is required. * Historic buildings may be retrofit to comply with the order. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Executive Order 13514」の詳細全文を読む スポンサード リンク
