國家電網(wǎng)公司電力科技館，北京，中國

Electric Power Museum of the State Grid Corporation of China (SGCC), Beijing, China, 2015

該項目為新建市政基礎設施及公共建筑工程，建設地點位于北京市西城區(qū)。用地西側臨菜市口大街，南側臨珠朝街，東側為代征城市規(guī)劃路，北側為文物保護建筑中山會館?？山ㄔO用地面積7478.57m2。規(guī)劃控制建筑高度60m（總高度）。北側距用地邊線30m范圍內(nèi)為文保建控區(qū)，建構筑物控高5m。項目包括220KV變電站主廠房及電力科技館兩部分內(nèi)容。其中地下3～5層為變電站主廠房，地下二層以上為科技館及電力客服中心辦公用房。

變電站與科技館整體設計原則

該項目是2009年市政府重點工程中煤改電工程的主要站點，為北京舊城內(nèi)居民集中供暖的燃煤鍋爐更換為蓄熱式電鍋爐提供支持。通過該工程可在采暖季壓減燃煤，減少CO2、SO2，氮氧化物的排放。通過清潔能源集中供暖，有效積極改善北京舊城冬季的空氣質量。

該項目是我國第一個對外開放可供參觀的220KV運行變電站，也是北京電力科技館最重要的展示廳之一。在設計前期，建筑師進行了大量的調查研究工作和詳細的建筑策劃，最終確定根據(jù)“科技與科普、地上與地下、建筑外觀與展示內(nèi)容、固定展示與定期更新相結合”的設計原則，本設施工程將科技館與變電站作為一個整體進行設計。該項目是市政商業(yè)地塊混合利用的典型案例，為我國新常態(tài)下城市用地存量的優(yōu)化開發(fā)提供了新思路。該項目也是工業(yè)建筑和民用建筑規(guī)范雙重應用的典型案例，是北京第一個在地下220KV運行變電站上整體建設的高層建筑，為后續(xù)城市用地存量優(yōu)化積累了寶貴的技術經(jīng)驗。

尊重古城城市空間序列設計原則

該項目建設用地為北寬南窄斜梯形，北側用地紅線外為文物保護建筑中山會館，規(guī)劃要求有30m建控區(qū)?？偲矫娌季殖浞挚紤]用地北側文物建筑的空間尺度。設計將12層主體建筑布置在用地南側，沿菜市口大街以簡潔、大尺度的入口空間為主；北側布置6層裙房，建控區(qū)內(nèi)以綠化停車為主，結合部分室外出入口及通風井等低矮構筑物保持舒展、低矮的老城尺度空間，成為南北區(qū)域的過渡空間。建筑由若干小體塊組合而成，此舉消解了對城市歷史街區(qū)的視覺壓迫，同時形成了豐富的建筑表情。

建筑表皮設計體現(xiàn)城市歷史記憶與現(xiàn)代科技交融的設計原則

建筑表皮設計致力于體現(xiàn)建筑與城市發(fā)展的關系，在材料的使用上采用具有歷史感的石材與現(xiàn)代節(jié)能玻璃幕墻相結合的處理手法，不同材料交融砌筑，應對周邊城市環(huán)境肌理。淡雅的洞石、深邃的啡鉆花崗巖主要用在菜市口大街界面，電力科技館在城市其他高層現(xiàn)代建筑群中顯得分外優(yōu)雅。石材幕墻表皮開洞設計暗合中國傳統(tǒng)紋樣神韻，是4.2m×4.2m的標準板塊，在工廠實現(xiàn)預拼裝后再運抵施工現(xiàn)場進行整體掛裝。Low-e玻璃外墻和晶瑩剔透的雙鋼化夾膠超白玻璃，和歷史街區(qū)相呼應，讓建筑反射天光云影和胡同院落，給人以平面胡同院落延伸生長到立面的視覺感受?！?/p>

Located in Xicheng Dis., Beijing, this project is a newly-built civil infrastructure and a public building. the site is to the east of Caishikou Rd., to the north of Zhuchao Rd., to the west of a planning road, and to the south of Zhongshan Guild Hall, which is protected as a cultural heritage. the parcel area is 7478.57m2, with a maximum gross height of the building restricted to 60m, except for the area within the range of 30m from Zhongshan Guild Hall, where no permanent construction shall exceed 5m. the project consists of two parts, part one is a 220KV transformer substation on basement level 3-5, on top of which is part two, a science museum and the customer service center.

Integration of the transformer substation and the museum

the project was a major transformer substation for Beijing 2009 "Coal to Electricity" project, one of the most important engineering projects of Beijing municipal government aimed at replacing collective coal burning boilers with regenerative electric boilers. this "Coal to Electricity" project is expected to cut down coal heating consumption in winter and reduce emission of CO2, SO2and nitrogen oxide. As a result, air quality in urban Beijing would be improved due to the enlarged collective use of clean energy.

The project is the first 220KV transformer substation in China that has a visitor's route open to the public. It is also one of the most important exhibition space in Beijing Electricity Science and Technology Museum. In the beginning of design process, the architect conducted massive surveys and made detailed programming plan. Eventually, a comprehensive design was proposed which put the museum and the transformer substation together as a whole, based on the concept of combinations of "science and technology and its popularization", "above and beneath the ground", "cladding and exhibition" and "permanent and renewable display". the SGCC Museum is a pioneer example of mixed use of infrastructure and commercial land, which provides new approach to optimize urban land storage in the New Normal time. In addition, it is a typical example of double application of both industrial and civil building code in China. It is also the first high-rise public building located above an underground 220KV transformer substation in Beijing. In conclusion, it provides a pioneer technical experience to deal with urban land storage problems.

Respect for space pattern of ancient Beijing city

The SGCC Museum's site is trapezoid in shape, of which the north side is wider than the south. To the north of the site lies Zhongshan Guild Hall, which is protected as a cultural heritage. Within the range of 30m from Zhongshan Guild Hall is the construction-restricted area. The master plan takes into consideration of the cultural heritage building and set the 12-floor main building on the south part of the side so as to make more space for it. Along Caishikou Rd., the exterior of the building is simple to show a large-scale entrance space. On the north part of the site there is a 6-floor podium building. To the north of the podium building is the constructionrestricted area. In this area there are outdoor facilities such as green space, parking lots, entrances and exits, ventilation shafts, etc. These low rise constructions keep the pattern of ancient Beijing city's urban fabric and serve as a buffer zone between the SGCC Museum and Zhongshan Guild Hall. Moreover, the SGCC Museum consists of several small volumes, which dispel the visual tension of the huge building and enrich the shape of the building.

Building envelop that reflects city history and modern technology

The design of building envelop aims at reflecting the relationship between architecture and urban development. In terms of material, stately stone, which provides a sense of history, is used in combination with modern glass curtain wall, which represents contemporary technology. This combination of materials responds to the complicated self-growing surrounding urban fabric. The simple and elegant travertine and deep and stately Baltic brown are mainly used on west facade in order to make the museum elegantly stands out from surrounding modern high-rise buildings. The stone curtain wall, with the pattern of openings on the wall reflecting traditional Chinese decorative pattern, has a standard 4.2m wide and 4.2m tall unit and is installed on site after pre- fabrication in factory. Low-E glass and double layered tempered and laminated super white glass respond to historic urban area and reflect sky and Hutong view, which provides a sense that the Hutong grows from ground to the building's facade.□

邵韋平：城市織補與開放

相對于業(yè)已成熟的建筑類型，國家電網(wǎng)公司電力科技館項目是在北京市“煤改電”這樣特定技術與社會背景下產(chǎn)生的“跨界建筑”。項目位于北京南城老區(qū)——《城南舊事》故事發(fā)生地，基地周邊正在進行大規(guī)模城市更新，高層住宅和商業(yè)建筑環(huán)繞，基地西側緊鄰菜市口大街，北面是一座文化保護建筑“中山會所”。項目在嚴謹?shù)慕ㄖ邉澲蜗逻M行了功能整合與空間拓展的嘗試，將220KV變電站主廠房與電力科技館兩項內(nèi)容結合起來，將“閑人免進的禁地”通過建筑語言巧妙地轉變成“科普課堂”。廠房與科技館在空間上是共有的，但同時也是各自自成體系的。原本內(nèi)向的空間特性在跨行業(yè)技術的支撐下得到了最大限度的開放，建筑可能性得到了拓展。高層建筑主體空間面向4個方向出挑并敞開，既有環(huán)境與新建建筑在視覺上產(chǎn)生互動。出挑部分的底面采用高反射材料，將古老的城市環(huán)境融合到新建建筑中。建筑一方面完整地向公眾呈現(xiàn)出特定歷史時期的城市功能形態(tài)；另一方面在滿足技術條件的基礎上，建筑師通過尺度的控制、空間組合與立面材料的搭配保證了新建筑與老城區(qū)文化肌理的融合與再生。國家電網(wǎng)公司電力科技館項目的策劃與實施過程為可持續(xù)發(fā)展背景下城市用地存量優(yōu)化開發(fā)提供了新思路，是城市基礎設施和公共建筑土地混合共享應用的典型案例，是在地下變電站上整體建設的高層建筑。

SHAO Weiping: Urban patching and openness

Compared to mature building types, the Electric Power Museum of the State Grid Corporation of China (SGCC) can be considered as a "trans-boundary" project. Located in the old district of south Beijing – where My Memories of Old Beijing took place, the site's surrounding area is experiencing large-scale urban renovation, with rapid growth of high-rise residential and commercial blocks. To its west is the Caishikou Street, and to its north a cultural-conservation building, the Zhongshan Club. Under strict architectural programming, the project made attempts at functional integration and spatial expansion, combining the 220KV substation powerhouse with the museum and deftly transforming a "staff-only" restricted area into a popular science classroom through architectural vocabulary. the powerhouse and the museum share the same space, while each maintaining its own system. Supported by trans-boundary technology, the originally introvert space achieved utmost openness, thus its architectural potential is considerably expanded. the main space of the high-rise building is open to all four directions, creating visual interactions between the new building and the existing environment. The undersides of the projecting parts employ high-reflective material to fuse the new building with old urban setting. On the one hand, the project presents its urban function as a whole to the public; on the other hand, having fulfilled technical requirements, the architect guaranteed both the new building's integration with the old city's cultural texture and their regeneration by means of scale control, spatial composition and disposition of facade materials. the SGCC Electric Power Museum's programming and implementation explored new ways of thinking for the optimization of urban land stock in the context of sustainable development. It is a typical case of joint application of urban infrastructure and public construction land, as well as an integrated design of high-rise buildings above the substation.
