Causeway Bay, where Hysan Place is located, is one of the
most vibrant commercial districts in Hong Kong. Residents
enjoy transportational and daily conveniences, but also suffer
from air pollution, heat island effect and a lack of open space.
The redevelopment of Hysan Place provides the opportunity to
implement the Building Sustainability Concept tailor-made for high
density urban areas.
Comprehensive researches and mock-ups conducted during
the planning stage for this 40-storey mixed-use office and retail
building led to an unusual design and unprecedented practices in its
construction and in its future leasing, operations and management.
Sustainable Design Amongst the most visible sustainable features
of Hysan Place are the Urban Windows – large openings at lower
levels in the building allowing efficient air flow through the area,
reducing wall effect and retaining a high level of permeability. They
provide the perfect setting for sky gardens, which help to reduce the
heat island effect with their lush greenery. Hysan Place will provide
a healthy indoor environment that emphasizes the use of natural
light and ventilation. Light shelf, solar shading and low emissivity
glazing help to encourage daylight and prevent heat gain depending
on outdoor conditions. Vents allowing choice of natural ventilation
will be built into the curtain wall, while free cooling is also available
on office floors by bringing outside air to directly lower indoor
temperature.
As drivers of change in the building industry:
• It is a green initiative driven by a private company
• Although a single building, it goes beyond its site boundary,
taking its neighbourhood into full consideration, aiming to
benefit the environment of the entire district
• It aims to answer some of the environmental problems
associated with high density and high rise development
• It is tailored to answer the climatic and geological conditions of
Hong Kong
• More importantly, it helps to drive the market and community
approach towards sustainability
希慎廣場位處銅鑼灣, 該區是香港最繁華熱鬧的商業區之一，居
民可享受生活及交通上的方便，但同時卻要面對空氣污染、熱
島效應及缺乏公眾活動空間等問題。希慎廣場重建項目提供機
遇,以實踐為高密度社區專門設計的可持續建築概念。
項目團隊於設計階段針對該40層高的寫字樓及商舖綜合建築項
目進行了全面的研究及模型實驗，使希慎廣場將擁有獨特的建
築設計及革新的建造、租賃、營運和管理方法。
可持續發展設計
建築設計最大的環保特色，是在低層部份留出了多個大面積的
「城市綠窗」，一方面使周邊的空氣更加流通，改善空氣污染
問題，另一面方使建築看起來更加通透，減低視覺上的屏風效
應。「綠窗」將廣植樹木，成為「空中花園」，提供市區中難
得的綠州，更有助減低城市的熱島效應。希慎廣場的環保設
計，通過引入自然光線及通風，締造更健康的室內環境。大廈
的玻璃幕牆採用了低輻射玻璃，並按方向設計遮陽板或反光
板，既節能又提供適當的自然光；幕牆更結合了通風口設計，
又可直接引入室外空氣，減低空調的耗能。
作為推動綠色建築的引擎:
• 這項目是由私人企業主動倡議的綠色建築改革。
• 雖然希慎廣場為單棟式建築，但其設計考慮卻遠超項目
範圍，以惠及整區的環境為目標。
• 建築研究旨在解決因高密度多層建築而產生的各種環境問題。
• 項目為香港氣候及地理環境提供專門解決方案。
• 更重要的是希慎廣場帶領市場及社會趨向可持續發展。
