The passive design of Jade Grove combines the three energy-saving characteristics of ventilation, insulation and shading, where comfort and energy-saving are achieved through planting, ventilation and the use of natural light.

The overall design makes use of the southerly wind in the summer and Hong Kong’s general southeasterly wind. Coupled with the buildings’ orientation, appropriate distance between buildings and bi-directional windows, the ventilation route allows the seasonal wind to flow throughout Jade Grove ensuring residents enjoy natural breezes.

The project is designing to take advantage of the light from the south and the north to reduce the heat load caused by sun exposure from the west. High performance low-e glass is used throughout the whole project to make use of natural light and reduce solar heat gain, preventing heat and stuffiness.

Some of Jade Grove’s many green measures include:

• 70% of the roof area is covered by high emissivity materials to alleviate the heat island effect
• More than 30% of the site area is covered with soft landscaping, including greenery and water features

Recycling facilities for metal, plastic, paper, cardboard and glass bottles have been provided

• Solar heat gain in the building has been minimised by careful planning of the main building orientation, i.e. avoiding west and east orientation whenever possible, and using high-performance glass such as low-e and tempered glass
• Energy-efficient appliances were selected
• Glass with better insulating performance such as low-e glass was used to reduce solar heat gain from windows

• About 23% of annual water consumption will be reduced by the use of water-wise sanitary facilities
• Washing machines with Grade 1 Water Efficiency labels have been provided

The indoor air quality meets the "Good Class" standards of the Indoor Air Quality Objective set by the Environmental Protection Department
