Value Created for the Environment Our large-scale residential project Wetland Seasons Park, located next to Hong Kong Wetland Park, carefully balances development and the environment by integrating innovative technology and environmental concepts throughout the building lifecycle, from planning and design to construction and operation. Planning and Design Utilizing computer aided air-ventilation analysis, we minimized the development’s impact with a stepped height design: the buildings nearest to Hong Kong Wetland Park are the lowest, creating a gradual elevation change. The designed breezeways spread throughout the development not only enhance flow of prevailing wind, but also create a transitional buffer in the form of a green belt between the residences and Hong Kong Wetland Park to soften the progression from human to wildlife habitats. Meanwhile, the facade was painted in earth tones and trees were carefully selected and planted to fit in with the surroundings. As Hong Kong Wetland Park is home to a number of migratory birds, building glazing had to be the right blend between transparency and reflectivity to avoid avian accidents resulting from migratory birds’ flight paths. Wetland Seasons Park features a wetland-themed clubhouse with an open, shared space. It makes the most of the view of the Hong Kong Wetland Landscape Case Study – Wetland Seasons Park Park, with its biodiversity and wildlife. And, to promote ecological awareness among the residents, there is a wetland-themed gallery with paintings and sculptures by local artists of subjects such as migratory birds. Meanwhile, low- reflection floor-to-ceiling glass walls reduce the impact of reflective light on birds. Lamps in public areas were designed to avoid the direction of the park to minimize light pollution. Natural ecology is incorporated into the development: the landscaped exterior makes up 35% of its total size. 35 existing trees were preserved, and more than 1,300 trees and 150,000 bushes – mostly native species – were planted. The landscape design adopted the ‘Shakkei’ (borrowed scenery) concept, incorporating the natural view from Hong Kong Wetland Park as a backdrop. The stepped height design and breezeways spread throughout the development A six-metre high noise barrier was erected along the site’s boundary to further minimize construction noise From the clubhouse, users can enjoy the natural scenery and wildlife of the Hong Kong Wetland Park Construction We established waste management plan and conducted noise, water-quality, air-quality and ecological-impact monitoring during the entire construction process. Specially arranged work hours and construction methods were also adopted. For example, no noisy foundation works were conducted when the Hong Kong Wetland Park was opened to the public. To further reduce noise, barriers, tailored design low-noise piling machines and mechanical equipment were deployed. An individual sewage treatment system ensured on-site sewage was treated before being discharged. And, to reduce dust from construction trucks, pre-cast concrete paving slabs were used for the haul road. 13 Sun Hung Kai Properties Limited • Sustainability Report 2021/22
