Sustainability Reports 2022/23

Wetland Seasons Bay CASE STUDY Wetland Seasons Park and Wetland Seasons Bay are large-scale residential projects adjacent to the Hong Kong Wetland Park which were completed in 2021 and 2022/23 respectively. Environmental considerations are prioritized throughout the building life cycle. Notwithstanding the compliance with statutory and planning requirements, we worked closely with consultants and other stakeholders to avoid the impact of noise, sewage, waste and emissions during construction on the Wetland Park and the surrounding environment. Planning, Design and Landscape • A stepped height layout design with a lower building height near the Wetland Park. A 40m-wide primary breezeway was introduced in the centre of each development supplemented by secondary breezeways to enhance prevailing wind flow from the Wetland Park to Tin Shui Wai Town Centre • Landscape buffer zone along the perimeter between the developments and the Wetland Park functioned as natural buffers to soften the transition between the developments and the Wetland Park. The building facades are in earth tones, while building glazing with low reflectivity to prevent birds from colliding with the glass panels. Lighting in public areas is carefully selected to avoid causing nuisance to the Wetland Park • External landscape area comprised 31% of the site area. 89 existing trees are preserved, and more than 1,500 trees and 250,000 bushes of native species were planted • Implemented waste management plan and monitored noise, water-quality, air-quality and ecological-impact during the entire construction process • No noisy foundation works were conducted during dry seasons when migratory birds were in Hong Kong and during the time when the Wetland Park was open to the public • Precast concrete paving slabs were used on haul roads during construction to reduce dust emissions • Six-metre high noise barriers were erected along the boundary of the developments to the Wetland Park to further reduce noise pollution • To promote environmental awareness among residents, the development also features a wetland-themed gallery showcasing paintings and sculptures, such as migratory birds, that highlight the beauty and importance of the surrounding ecosystem Construction During construction, we implemented measures to minimize our environmental impact: In the Quality Building Awards 2022, Wetland Seasons Park earned the Grand Award, the highest honour in the Hong Kong Residential (Multiple Buildings) category.
