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
