Green Features

Site Aspects

  • Providing adequate water spraying on roads and vehicle washing facilities
  • Providing noise barrier for piling works
  • Providing wastewater treatment plant to reduce water pollution during construction
  • Providing acoustic treatment for major noise sources such as generators and chiller plants
  • Providing vegetation roof covering 53.4% of the total roof area

Materials Aspects

  • Using FSC and PEFC certified timber for temporary works during construction
  • Using no chlorofluorocarbon (CFC)-based refrigerants in HVAC&R systems
  • Providing waste recycling bins for collection and segregation of recyclables including paper, plastic and aluminium cans, and designated area for collecting cardboard and glass bottles

Energy Use

Adopting the followings as major energy saving measures:

  • High performance building envelope
  • High efficient A/C equipment
  • Demand control ventilation in carpark and office
  • Energy efficient lighting system
  • Use of natural lighting with daylight sensors
  • Air economizers
  • Providing 164 Mono-crystalline PV panels, 16 thin-film panels and 8 BIPV panels for renewable energy
  • Using energy appliances having Grade 1 EMSD energy label, registration record of EMSD voluntary energy efficiency labelling scheme or energy star label
  • Adopting Central Control and Monitoring System (CCMS) for system control and Building Energy Management System (BEMS) for energy monitoring

Water Use

  • Installing water-efficient lavatory faucets and shower heads to achieve annual water saving of 40.5%
  • Adopting drip type irrigation system and rainwater harvesting system to reduce water consumption for irrigation
  • Installing urinals and water closets with efficient flush flow rate to achieve 39.5% of reduction in sewage volume

Indoor Environmental Quality

  • Installing mechanical exhaust systems with carbon filter in refuse storage and material recovery chambers
  • Undertaking flush-out of normally occupied spaces prior to occupancy and replacement of all filters (new MERV 13 filters) prior to occupancy
  • Carrying out IAQ test to demonstrating compliance with “Excellent” criteria for CO, NO2 O3 and VOCs
  • Providing increased outdoor ventilation exceeding ASHRAE requirements by at least 30%
  • Providing daylight sensors and occupancy sensors for automatic lighting control system

Innovations and Additions

  • Installing light pipe to utilize natural daylight to the Library so that less artificial light is required in daytime, and hence the energy consumption can be reduced
