Green Features

Site Aspects (SA)

31.2% greenery is provided on site, with horizontal and vertical soft landscape
AVA for improvement on pedestrian level air ventilation in the vicinity by lower building height of one block, increase of the width of building separation and optimized building shape
Roof materials meeting the SRI78 or vegetation roof covering 70% of the total roof area
Over 12% VDF at the façades of the lowest floors of neighbouring sensitive receivers
To avoid lighting pollution, exterior lighting fulfils the requirements in environmental zone E3

Materials Aspects (MA)

Shaft Grouted Barrett (special pile) reduces concrete use
Modular and standardised components in building with 40% prefabricated building elements including facades, staircases, slabs and partition walls.
69.5% of timber and composite timber products are from sustainable source
66.3% construction materials were manufactured within 800km from the site

Energy Use (EU)

Permeability of the site at low to high zone is 43.37% to 63.82%
Average solar irradiance of all facades for Block1 and Block2 is 230.89kWh/m² and 218.63kWh/m² between Apr-Oct
Overall OTTV for this portion of the development is 17.0W/m²
22.59% habitable areas complied with the ventilation requirement (prescriptive approach)
94.2% of the habitable spaces achieve a VDF>12%
MVAC energy saving of 98.6% achieved by natural ventilation on all lift lobbies and corridor areas and high efficiency fans in plantroom and other spaces.
Block1 and Block2 is able to achieve lighting energy reduction of 43.2% and 37.5%
Lift energy saving greater than 10% in comparison with BEC2012
PV Systems contributing 2.6% communal area energy use

Water Use (WU)

Water efficient devices adopted to achieve 31.8% of annual water saving and 41.8% reduction in effluent discharge volumes.
Water leakage detection system at water tank, pump rooms and the lowest floors pipe duct.
With the use of native species, high efficiency irrigation including sprinkler and drip systems and the harvested rainwater system, 64.9% of freshwater saving for irrigation is achieved.

Indoor Environmental Quality (IEQ)

Various measures to enhance indoor environmental quality. Design considerations including but not limited to the following:-

Security, Plumbing and drainage hygiene and health, waste disposal facilities,
Indoor air quality (IAQ), thermal comfort, domestic block natural ventilation
interior lighting, vibration control,
provisions for access for disabled persons, and provision of amenity features for enhancing building quality and improving O&M

Innovations and Additions (IA)

Two-level lighting control
Deodourising system (Biological agent) for Refuse Collection Point
Multi-sensory Map
Root Zone Irrigation System
Twin Tank
Hard Paved Construction and Reuse (Improve site safety and cleanliness)
Air Pollutant Removal Pavers and Eco-Glass Paving
