DSD is committed to provide world-class wastewater and stormwater drainage services enabling the sustainable development of Hong Kong. Aiming at improving drainage services in an environmentally responsible manner, DSD is strongly motivated to go green in their functional building.

Environmental protection and measures for reducing overall project carbon emissions have been adopted in an effort to minimize impacts to the environment. To enhance the sustainability design, the major green features adopted in this project are highlighted below.

Neighborhood Consideration

• 40% of the total roof area is covered by greenery and vertical green walls are installed to enrich the livelihood building outlook, reduce the local heat island effect, reduce heat dissipation from building.
• Effective deodorizing system are installed to control the source of odour and improve the air quality
• Building equipment and lighting installations are designed and operated to minimize the noise and light pollution nuisance to neighborhood.

Whole Life Cycle Consideration

• Energy saving features are installed covering optimized lighting layout, high efficient air-conditioning and mechanical ventilation and high performance envelope for solar heat gain reduction.
• Proactive use of structural elements and choice of materials are adopted to reduce embodied energy.
• Sustainable energy management by monitoring the different energy consumption profiles of ventilation system, outdoor lighting, general lighting & small power and irrigation systems.
• High-efficient water saving sanitary fittings are installed and monitored regularly.
• High efficient irrigation technology provided to save portable water use.

The key project success is to bring a positive impact to the public by DSD’s high devotion in enhancing a green, harmonious and sustainable environment as well as caring of the general public.
