主题：【讨论】好房子的标准 -- 丁不二

跑蹄总是很过瘾,这当猪总是比当机器舒服。“呔，又偷懒！”不知道什么时候中的紧箍咒，还是他一直就在，只是不曾觉察过。好，接着掰LEED。

区区翻了一下维奇,发现关于7 WTC的每句话(除了关于安全性的以外)都是在LEED拿分的,可见维奇有高人; 区区尝试着注释一下LEED怎么给建筑打分,希望那些有玉的手痒痒8。

The new 7 World Trade Center has 49 stories and is 741 ft (226 m) tall.[47] The building has 42 floors of leasable space, starting at the 11th floor, and a total of 1,700,000 sq ft (158,000 m²) of office space.[47]

（选点大类，旧区重建，1分；在公共交通完善的地方发展，容积率高于2.5，1分; 在0.5英里内有地铁站或巴士站,1分;）

The first ten floors house an electrical substation, which provides power to much of Lower Manhattan. The office tower has a narrower footprint at ground level than its predecessor so the course of Greenwich Street could be restored in an effort to reunite TriBeCa and the Financial District.[48]

David Childs worked in conjunction with glass artist and designer James Carpenter to create a design that uses ultra-clear, low-iron glass to provide reflectivity and light, with stainless-steel spandrels behind the glass to help reflect sunlight.[49]

Stainless steel used in the building façade is molybdenum-containing Type 316, which provides improved resistance to corrosion.[50] To enclose the power substation and improve its aesthetics, the base of the building has a curtain wall with stainless steel louvers that provide ventilation for the machinery.[51] During the day, the curtain wall reflects light, while at night it illuminates with blue LED lights.[52] The curtain wall around the lobby uses heavily laminated, heat-strengthened glass that meets high standards for blast resistance.[53] At night, a large cube of light above the lobby also emanates blue light, while during the day it provides white light to the lobby, and at dusk it transitions to violet and back to blue.[54] Inside the main lobby, artist Jenny Holzer created a large light installation with glowing text moving across wide plastic panels.[49] The entire wall, which is 65 ft (20 m) wide and 14 ft (4 m) tall, changes color according to the time of day. Holzer worked with Klara Silverstein, the wife of Larry Silverstein, to select poetry for the art installation. The wall is structurally fortified as a security measure.[55]

The new 7 World Trade CenterThe building is being promoted as the safest skyscraper in the U.S.[56] According to Silverstein Properties, the owner of the building, it "will incorporate a host of life-safety enhancements that will become the prototype for new high-rise construction".[57] The building has 2 ft (60 cm) thick reinforced-concrete and fireproofed elevator and stairway access shafts. The original building used only drywall to line these shafts.[58] The stairways are wider than in the original building to permit faster egress.[58] Steel columns are encased in much thicker fire protection, which consists of a medium-density, portland cement-based product that adheres well to the steel columns, among other advantages over alternate types of spray-applied fire-resistive material.[59]

7 World Trade Center is equipped with Otis destination elevators.[60] After pressing a destination floor number on a lobby keypad, passengers are grouped and directed to specific elevators that will stop at the selected floor (there are no buttons to press inside the elevators). This system is designed to reduce elevator waiting and travel times. The elevator system is integrated with the lobby turnstile and card reader system that identifies the floor on which a person works as he/she enters and can automatically call the elevator for that floor.[61]

(说实在的,这就安全了?)

In conjunction with Scott Chrisner of Chrisner Group, Tishman supported the LEED gold status for 7 World Trade Center in the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program. The certification will name 7 World Trade Center New York City's First ‘Green’ Office Tower. [62] Nearly 30 percent of structural steel used in the building consists of recycled steel.[63]

Rainwater is collected and used for irrigation of the park and to cool the building.[49]

(省水大类,雨水回收,灌溉园林,创新废水处理技术,节约用水,可能高达5分;能源及大气环境大类,减少冷冻剂使用,可能有1分)

Along with other sustainable design features, the building is designed to allow in plenty of natural light, power is metered to tenants to encourage them to conserve energy, the heating steam is reused to generate some power for the building, (室内环境大类,冷热可由租户调节,可能高达4分;能源及大气环境大类,可再用能源,可能有1-2分,能源使用优化,可能有5分左右)

and recycled materials are used for insulation and interior materials.[64][65]

(选料大类,回收能源使用,可能有1-3分)

粗算下来,已有30分在手;再加上没有在维奇反映的室内用料低放射,建筑废料管理等估计再加10分问题不大。避重就轻的，还没用上太阳能，就已经做到LEED金质认证乐，好买卖。
