華潤大廈建於80年代，屬當時灣仔區的地標性大廈。為配合灣仔北區的商業發展活動，以及提高企業形象，業主決定開展總部翻新工程。此翻新工程除了保存建築原物，更加入綠化理念，改善周邊環境，符合成本效益，令它成為二十一世紀可持續發展的設計典範。

翻新前後
翻新大廈的主要的目的是藉?重建外牆，令大廈外觀上更統一。工程主要分為三方面：重新規劃裙樓、更新外牆以及改善辦公室室內空氣質素。

外牆上採用了垂直、簡潔整齊及具節奏感的設計，令大廈及平台在外觀上變得一致。建築師與大廈租戶協調後，便著手拆除大廈幕牆原有的非結構性外牆及窗戶，由上至下換上可獨立分組裝嵌的低放射性雙層玻璃幕牆。玻璃幕牆能有效減少吸收太陽的熱力，讓只有百分之五的太陽能傳送到室內，令空氣調節的冷凍負荷減至最低。另外，外牆的LED照明系統，大大提升了大廈的夜間外觀之餘，又能達至節能及環保目的。

至於大廈的平台經過重新設計，移除平台的數個樓層（2至5層的一些部份），加強空氣流通。新置的景觀平台，拆卸並重組裙樓的空間，部份公眾通道跟平台大堂相連，方便使用者。大廈的自然通風及採光照明得到改善，既美化了零售商店的外觀，又提高了鄰近地區的流通性。而原有的混凝土公眾通道，則改為玻璃簷篷配以擋風玻璃的行人通道，令環境更舒適。

可持續發展元素
華潤大廈是首個預先得到美國綠色建築協會的能源與環境設計先鋒(LEED)金獎認證的翻新工程。綠化後不但可減少營運成本及節能，改善了空氣質素，更為用者提供更佳的室內環境。為實現綠色地標，設計和施工考慮於整個翻新程序都飾演重要角色:

翻新工程中至少兩成材料是由就近地區生產的，以減少在運輸過程中所產生的二氧化碳。新建材當中循環再用的成份更佔生產成本百分之二十，鼓勵廢棄物料之使用。項目重新使用百分之九十五的現有結構性骨架、樓板和屋頂，務求延長建築物的生命週期。我們採用的建築廢物管理計劃，將回收至少百分之七十五的無毒建築及拆卸廢料。鋪有反射太陽能的天台和全新的屋頂花園，將減少建築物所產生的熱島效應。

大廈內置有低流量水龍頭和沖水設施，每年可節省相等於 4.5個奧林匹克標準游泳池容量，約11,180立方米的用水。而室內空氣質量方面，新的風櫃將會安裝二氧化碳需求控制通風系統，以保持二氧化碳在室內的水平，並根據接收的數據而調整戶外進入室內的空氣量，透過引入適量的自然風，達至改善空氣質素和節能。

選擇室內裝修材料時，我們特別選用低有害化學物質排放量的油漆，地毯，膠粘劑和密封劑等，並會選用含低揮發性的有機化合物材料，這不但可以減少室內的空氣污染，也可改善用戶的健康。

大廈內亦設有一個創新的照明系統，結合了日光感應器和人流感應器的技術，燈光會在超過預設時間的空置空間自動熄滅，以減低照明成本。為了令建築物用戶減少製造廢物，大廈亦會推行一系列措施及安裝各項有關設備，鼓勵用戶將廢物回收及循環再用。

翻新後的華潤大廈，非但體現了綠化商業大廈的可行性，而且更符合成本效益。這個翻新工程，既保存了建築原物，同時令它成為二十一世紀可持續發展的設計典範。

The China Resources Building (CRB) was used to be an icon of 1980s. To cope with the growth of commercial activities in North Wanchai and for the advancement of the corporate identity, the owner made decision for an evitable move.

Ronald Lu & Partners took this challenging renovation of China Resources Building to show that greening an existing office building is technically feasible and cost effective. Most importantly, this refurbishment work has proven its success in preserving an architectural icon in the urban fabric while bringing her up to 21st century standards of sustainable design and upgrading the Cooperate identity at the same time.

To make a statement for the identity of the building, the refurbishment of the building envelop aimed to restructure the building skin as an entity. By means of simple and neat vertical features arranged in a rhythmical pattern throughout the building, the tower and the podium become unified. The integration of energy saving and environmental friendly LED lighting scheme transforms the building appearance and enhances the building presence at night time while maintaining the simplicity of the architectural design during the day.

The re-planning of the podium has introduced landscaped courtyards for the enjoyment of both the building users and the public by removing and restructuring the building mass at the podium floors. The micro-climate in terms of cross natural ventilation, lighting and building permeability for the building itself and the neighbhourhood are significantly enhanced.

The public walkways which were used to be covered by concrete structure have been transformed to weather protected passages with glazed canopies and windscreens for a more pleasant moving space. Furthermore, part of the existing public walkways at G/F floor and podium floor are integrated with the podium lobbies in order to enhance the convenience of pedestrian circulation.

CRB is the first pre-certified renovation project to achieve LEED Core & Shell Gold Rating in Hong Kong. Not only will the greener CRB reduce cost and energy consumption, the improved air quality provides a better interior environment for its users. The tower’s original skin of white mosaic tiles is being dressed up by a new curtain will to reduce solar gain. Only 5% of solar energy will be transmitted into the interior and lead to a reduced cooling load for improved energy efficiency. Materials of the new curtain wall are regionally manufactured thus minimizing the carbon footprint resulting from their transportation. At the same time, the project reused 95% of its existing structural walls, floors and roofs to extend the life cycle of the building stock.

It has also been awarded with the Perspective Awards, American Institute of Architects and “the most beautiful commercial property in China” in 2013 with its distinctive and brilliant sustainable design.
