華電天寧寺廠區又名第二熱電廠，自1976年起承擔了為中南海等中心城區供熱任務。2009年機組關停，廠區面臨融入城市、適應新時代需求的兩大問題。廠區北側為城市道路，街區內部道路系統封閉，街區風貌和通達性較差。東側緊鄰古剎天寧寺，但區域建筑整合不甚和諧。基于以上需求和問題，對第二熱電廠進行改造。

一期改造建筑為主廠房東側南至北的建筑群落，建筑原功能涵蓋了辦公、宿舍、浴室、食堂、工業用房、大型庫房、生產車間等多種類型。設計關注于重整廠區內部空間，梳理多種尺度以及建筑關系的作用，重塑廠區與天寧寺及現代城市關聯性。

設計以延續場所記憶、協調廠區與周邊關系為出發點，力圖修舊如舊，漸進式發展，為遠期建設提供基礎。廠區周邊地域復雜，街道不通暢，信息不貫通。但城市因天寧寺的存在本身具有獨特的歷史特點和文化環境。城市建設需要根據特有文化，原有建筑同新型城市特點結合起來，使改造既延續場地記憶，又同周邊建筑和諧統一。

區域交通順暢對增強區域活性意義非凡。因此首先在城市設計層面整治臨街界面，疏通廠區臨界道路，在城市客廳和街區邊界的命題下確定開放性平衡點。進而為廠區疏通內部道路，增強場地內外通達。

項目尊重原建筑布局、形態，建筑以傳統材料及工藝（磚、水磨石、干粘石）為主體，輔以少量新建筑材料（泡沫鋁板、火山巖、氟碳鋼板、玻璃幕墻）作為功能補充和形式邏輯的平衡點。

室外場地及景觀，通過鋪裝類型（透水鋪裝、預制混凝土板、碎石）、植物選配、微地形處理，塑造與初始空間相近、質感微差的場所。避免盲目增量和面目全非，并協調尺度巨大的主廠房和古韻濃厚的天寧寺。設計保留了場地原有的部分構筑物和設備，并結合設備設置景觀小品、雕塑裝置等。

2 城市肌理/Urban fabric

Huadian Tianning Temple Factory, also known as the Second Thermal Power Factory, has been supplying heat to the central city areas of Beijing since 1976. After the main generator unit was shut down in 2009, the factory faces the challenges of integrating into the city and meeting the needs of the new era. The northern side of the factory is bordered by urban roads, and the roads inside the block are narrow and full of dead ends. The eastern side of the factory is adjacent to Tianning Temple, a well-known Buddhist holy site in Beijing.

The design focused on the reconstruction of the inner space of this block, tried to combine a variety of buildings in different scales, and reshape the relationships between the factory and Tianning Temple, and the modern city environment.

The renovation is based on the idea of maintaining the memory of the place, to coordinate the relationship between the factory and the surrounding areas, trying to restore the old and develop it progressively , providing a basis for the long-term construction.

At the level of urban design, we try to repair the street interfaces, making it the city's living room and as the boundary of the block. In turn, the internal roads are unblocked to enhance accessibility of the site.

We respect the original architectural layout and form of this area. The main part of the factory adopts traditional materials and crafts (bricks, terrazzo, dry clay stone and wood), and a small amount of new materials are applied, like aluminium foam panels, volcano rock, fluorocarbon steel panels and glass curtain walls, as a functional complement and a balance of formal logic.

The outdoor site and landscape are shaped by paving types (permeable paving, precast concrete slabs, gravels), plant selection, and microtopography treatments, so that the place is similar to the original space with a slight difference in texture. It avoids blind increments and recognition and coordinates the differences of materials and scales between the factory and Tianning Temple.
