5 建築物 建造與運作建築物消耗大量的自然資源與能源， 同時產生影響環境的廢物與污染物，這些都會 對將來居住或使用者造成潛在的健康危害，甚 至影響其工作生產力 台灣住家與商用建築物所使用的電力，約佔總 耗電的三成。依據2003年全國能源的統計，電 力消費統計共計1,959億度電，住宅部門電力消 費391億度電佔全部的19.98%；商業部門電力 消費208億度電為全部的10.64%，兩者用電合 計佔全部的30.6%，且住宅用電每年平均以 4~5%的速度成長

6 通常愈是開發的國家，相對越是都市化， 所以其建築部門耗能量愈高，依據國際能 源局的估計，已開發國家的住宅與商業建 築約消耗主要能源的36%。
根據2003年世界經濟合作與發展組織 （OECD）的「永續環境建築：挑戰與政策」 報告，指出全球建築物消耗掉32％的資源， 12％的水、以及40％能源，除此之外，40 ％的掩埋垃圾也來自建築物

17 發展綠建築的目的 希望建築物設計、建造與運作的過程中能對 環境、經濟、健康與生產力提供顯著改善

18 綠建築認證系統 臺灣在1999 年推動EEWH，是繼英國 BREEAM、美國LEED 與加拿大GBTOOL 後第四個綠建築評估制度，截至目前為止 世界已經有將近20 個綠建築評估系統

22 History LEED began in 1993 by Natural Resources Defense Council (NRDC) scientist Robert K. Watson, Founding Chairman of LEED Steering Committee (until 2006), led to a general agreement that the Committee consists of non-profit organizations, government agencies, architects, engineers, developers, builders, product manufacturers and other industry leaders.

23 The Technical Committee members in 1996 includes
USGBC co-founder Mike Italiano, Architect Bill Reed and Sandy Mendler, Builder Gerard Heiber and Myron Kibbe, Engineer Richard Bourne, Tom Paladino and Lynn Barker. LEED has grown from one committee (6 volunteers) to 20 committees (200 volunteers).

24 LEED LEED（Leadership in Energy and Environmental Design）「能源與環境先導 設計」是美國綠建築協會（U.S. Green Building Council, USGBC）所制訂之高效 能綠建築之市場導向式評估系統，用以鼓 勵永續性建築的發展與實行，並提供業界 作為設計更健康、更環保與更有利潤的建 築物之準則 LEED於1994年開始制定，1999年正式公佈 第一版本並接受評估申請

25 LEED NCv1.0 pilot program released in 1998
LEED NCv2.0 released in March 2000 LEED NCv2.2 released in 2005 LEED v3 (LEED 2009) released in April 2009 Today, LEED consists of a suite of nine rating systems for the design, construction and operation of building, homes and neighborhoods. Green Building Design & Construction • LEED for New Construction & Major Renovation • LEED for Code & Shell Development • LEED for Schools • LEED for Retail New Construction (planned 2010)

26 Green Interior Design & Construction
• LEED for Commercial Interiors • LEED for Retail Interiors (planned 2010) Green Building Operations & Maintenance • LEED for Existing Buildings: Operations & Maintenance Green Neighborhood Development • LEED for Neighborhood Development Green Home Design & Construction • LEED for Homes

29 九個各自獨立之LEED版本 LEED-NC：LEED for New Construction 新建築版 : 新建築物或大範圍增改建 案之認證申請。 LEED-EB：Existing Building 既有建築版:既有建築或既有建築局部改善之認 證申請。 LEED-CI：Commercial Interiors 商業內裝版:新建或既有辦公建築內之承租戶 室內裝修改善認證申請。 LEED-CS：Core & Shell Development 結構體版: 供僅負責及擁有建築物結構 體，但不負責承租戶室內裝修設計之業主或開發商申請認證。 LEED-School: School學校版。 LEED-Retail: Retail商店設計。 LEED-Healthcare: 醫療設施。 LEED-H：Homes 住宅版 : 單一基地上，三層樓以下之獨棟或雙拼住宅之認 證申請。 LEED-ND：Neighborhood Development 鄰域開發版: 新建集合住宅、商業或 混合開發案之認證申請，評估範圍包括街廓鄰里，生活機能、公共設施等， 但不包括建築物。

30 LEED NCv2.2 LEED for New Construction and Major Renovations version 2.2 contained the same credits as the new NC v2009, but had fewer points. There are 69 possible points and buildings can qualify for four levels of certification: Certified points Silver points Gold points Platinum - 52 points and above,

31 USGBC launched in 2009 LEED v3 having 100 base points +6 points for innovation and 4 for regional priority (LEED 2009) which consists of a new continuous development process, a new version of LEED online, a revised third-party certification program and a new suite of rating systems. Buildings can qualify for four levels of certification: Certified points Silver points Gold points Platinum - 80 points and above

32 LEED-NC 3.0 LEED-NC 3.0 規定Prerequisites 項目全數通 過且在Credit項目滿分110分中得到40分以 上就算是LEED認證合格，再依得分高低分 下列四種等級： 合格認證(Certified) 40~49分 銀級認證(Silver) 50~59分 金級認證(Gold) 60~79分 白金級認證(Platinum) 80~110分

Built in 1968, with a $32 million renovation in 2009 by current owner Brookfield Properties, 1225 Connecticut Avenue is the "second redeveloped building in the United States and the first within the major business districts of the East Coast to achieve LEED Platinum status." Tenants include Citibank, Global Justice, and Morgan Stanley Smith Barney (June 21, 2010). 1225 Connecticut Avenue in Washington, D.C., is the first redeveloped office building on the East Coast to receive LEED Platinum status.

39 Carbon Trading Potential
LEED-NC 3.0 will include a requirement for a carbon footprint (carbon building print) and a significant reduction of green-house gasses (carbon dioxide, methane CH4, nitrous oxide N2O, sulphur hexafluoride SF6 ) beyond a baseline level. The reduction in carbon dioxide must be measured based on the direct and indirect carbon dioxide and equivalent reductions.

40 The efforts to quantify emission and reductions in emissions will be in an effort to monetize the climate change externality(外在 性) in the same way that a Kyoto Clean Development Project (carbon project) does. The Kyoto Protocol, adopted on 11 December in Kyoto, Japan, is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC), aimed at fighting global warming. As of November 2009, 187 states have signed and ratified (使正式生 效) the protocol.

41 Participation in the Kyoto Protocol, as of June 2009, where dark green indicates the countries that have signed and ratified the treaty, grey is not yet decided and red is no intention to ratify.

42 Kyoto is intended to cut global emissions of greenhouse gases.

43 General Analysis Since 2000, over 5 billion square feet of commercial building space is involved with LEED green building certification system. Construction yields an annual output of U.S. $4.6 trillion, contributing to 8-10% of the global GDP encompassing a workforce of 120 million people and billions of transactions each day.

44 Buildings represent 38.9% of US primary energy use.
Building are one of the heaviest consumers of natural resources and account for a significant portion of the greenhouse gas emissions that effect climate change. In the US, buildings account for 38% of all CO2 emissions. Buildings represent 72% of US consumption. Building use 13.6% of all potable water, or 15 trillion gallons per year. Buildings use 40% of raw materials globally (3 billion tons annually).
