Green features are adopted in creating a sustainable mixed-use development
Parkview Green is a LEED®-CS Platinum certified mixed-use development with grade-A office space, a six-star hotel and retail facilities. It is four buildings encased in a glass and ETFE (ethylene tetrafluoroethylene) envelop that creates an easily controlled microclimate which keeps energy bills at a minimum over the projects lifecycle.
The project is designed by Hong Kong-based architects Integrated Design Associates, while Arup provides a full multidisciplinary service for the project including structural, MEP, façade, fire, building physics, geotechnical and traffic engineering.
Key passive and active green features adopted in this development include an environmental envelop, earth pre-cooling system introducing air underground before entering the interior, chilled ceiling radiant cooling, and under-floor air conditioning. These well-orchestrated passive and active systems significantly reduce cooling and heating energy.
Hybrid ventilation allows natural ventilation and free cooling modes to be operated when outdoor condition is desirable. This hybrid system contributes to 60% energy saving in summer when compared to a conventional office air conditioning system. In winter the highly insulated collective façades can offer up to 80% energy saving over the conventional office designs.
Grey and storm water recycling system are being used for water conservation purpose. Rainwater collected from roof and paved areas is recycled and pre-filtrated for irrigation in landscaping area. Waste water from sinks, showers and washing faucets is also treated for
flushing and landscape irrigation.
Material selection is based on sustainability consideration, therefore, building materials with high recycled content are adopted, including recycled materials from building demolitions for back-filling of site, substantial use of steel work and ETFE as recyclable materials, and using softwoods for construcion purposes. Native plants and trees are selected for landscape so that irrigation and landscape management can be reduced.
