Tin Shui Wai Hospital

There was a need to construct a new hospital to strengthen the public hospital services in the New Territories West Cluster (NTWC) area to meet the increasing population and service demand growth. In view of this, the construction of Tin Shui Wai Hospital (TSWH) had been commenced in 2013 and the project was completed in September 2016.

The newly-built public hospital is a 12-storey complex with a single-storey basement, which has a capacity of 300 in-patient and day beds, providing a wide range of medical services. These include in-patient services for emergency care, rehabilitation, convalescent and palliative care, ambulatory services, community care services, and diagnostic and ancillary services.

With a strong emphasis on energy conservation, the building has adopted various forms of energy efficient features, including a number of passive designs in architecture and active design features, renewable energy technologies, greening and recycling features. For example, many glass curtain walls have been installed on the building façade to facilitate a high level of sunlight penetration, thus reducing the energy required for lighting up the building during day time. The use of renewable energy such as installing a solar hot water system also helps to conserve energy.

To foster a pleasant and relaxing environment for patients and staff, the greenery coverage is maximized on the appropriate roofs, terraces, courtyard and facades of the building. Meanwhile, rainwater and condensate water recycling systems have been installed for landscape irrigation.

Sports Centre, Community Hall and District Library in Area 14B, Shatin

The Sports Centre, Community Hall and District Library are built to meet the strong demand for sports facilities, a new venue for organizing community activities, and improved library services and facilities in the district of Shatin.

Overall street view of the complex building
The construction of 4-storey sports centre, 6-storey community hall and district library were completed in March 2016 and they have adopted passive designs to facilitate natural ventilation and the use of daylight to reduce consumption of energy significantly. Furthermore, renewable energy technologies including photovoltaic system and solar hot water system are installed for environmental benefits.

The building form is in composition of different volumes to create important green void spaces in the design. 15m wide ventilation corridor with multi-levels landscape deck at various levels is introduced between the volumes. The location of such ventilation corridor is designed in response to the existing massing disposition of the adjoining residential towers immediately behind the site. The void spaces are designed to be green, open, naturally ventilated and penetrated with natural day light for public use.

To provide a comfortable and enjoyable environment for the residents, the building complex integrates greening features on appropriate rooftops and facades, including a climber system for creating an attractive micro-garden on facades. A rainwater recycling system is also installed for irrigating the large coverage of green area.

West Kowloon Law Courts Building

To meet the increasing demand for court services and to enhance operational efficiency, the Tsuen Wan Magistrates' Courts, the Small Claims Tribunal, the Coroner's Court and the Obscene Articles Tribunal have been relocated to the newly commissioned West Kowloon Law Courts Building (WKLCB) which has a total net operational floor area of about 16,500 square metres, providing sufficient spaces to accommodate necessary facilities to support court operation.
WKLCB comprises two tower blocks with bridge linkages connecting both towers in the middle. The building facades adopts both vertical and horizontal sun-shading to reduce heat gain and optimise the energy efficiency of air conditioning. The building also makes use of daylight and achieves high thermal performance through the adoption of double glazing and contributes to substantial energy savings through passive means. Other environmental features include the installation of photovoltaic panels on the building roof, rainwater harvesting and landscape irrigation, as well as maximising greening on rooftop and vertical greening on building facades to reduce energy and water consumption.

Construction of a 30-classroom Primary School in Kai Tak at Site 1A-4

External landscape areas are arranged in a network of circulation spaces, square, porticos, herb garden and courtyards on different levels as internal oasis for staff and students to experience contemplative space. Floor to floor connectivity is thus enhanced by this concept, while the distance between students and nature is shortened. The design has provided accessible routes to various landscape areas to arouse student’s passion for learning and encourage spatial discovery by students as part of their learning process.

Green coverage around the clinic
To promote positive interaction and provide social and therapeutic spaces within the medical tower, recreational and functional spaces with therapeutic purpose are arranged at the rehabilitation garden, whereas non-medical resting environment is provided in the staff garden on roof. Also, to enhance visitors' and patients' experience through planting, and to maximize the visual connection with existing hospital complex and adjacent greenery/landscape settings, the building showcases not just the roof gardens, but also the extensive vertical green wall vegetated on both building façades and link bridges in form of a "Green Back-Drop". The "Green Back-Drop" comprises a series of external balconies/planters extending up to the roof garden and extensive green roofs on link bridges. The link bridges also act as a functional and aesthetical green corridor for connecting the new building to existing medical blocks within QEH compound. A rainwater recycling system is also in place for irrigation.

Indoor Recreation Centre in Area 4, Tsing Yi

The landscape design provides a pleasant environment for people to appreciate the nature and enjoy outdoor life. As the site is surrounded by woodland area, new trees of median to small size are selected to further enrich the overall greenery. Terraces of lawn area will be provided at the roof decks (i.e. green roof at 2-4/F) to provide a thermal control, prevent surface runoff and allow open view to the adjacent area.
