Green Features



Marina Barrage is a showpiece of environmental sustainability, and won the Green Mark Platinum Infrastructure Award, a top award at the BCA Awards organised by the Building and Construction Authority in May 2009.

​Green principles are applied in all aspects of the design, construction and operation of the barrage to utilise energy and water efficiently, and minimise waste generated.

Green Roof


The iconic Green Roof uses 100% recycled plastics and eco-friendly drainage cells.

This large rooftop garden also provides natural heat insulation for the building. The grass and soil shield the building from the sun and reduces maximum surface temperature by 3˚C. ​

Double–glazed Panels

Double-glazed glass panels also reduce heat penetration, and minimise the amount of electricity the air-conditioning system needs to use. ​

Solar Park

​​Solar Panels

The Solar Park is one of the largest collections of solar panels in Singapore. The 405 panels supplement daytime electricity required for lightings in the gallery and offices in the barrage.

The Solar Park generates 76,000kWh electricity per annum, which is equivalent to the monthly electricity consumption of about 180 average households in Singapore.

Natural Lighting and Ventilation


The Pump House at Marina Barrage uses glass and louvers for its external walls so that the interior is lit by natural lighting. This also eliminates the need for air-conditioning and reduces electricity consumption and operation costs. ​

Using Water from Reservoir to Cool System

​​Marina Barrage uses reservoir water to cool down the drainage pumps and generators when they are operated. This has saved the barrage about 1,400m3 of water per annum (2011), which is about one Olympic-size swimming pool of water. ​

Energy and Water-Efficient Fixtures

Marina Barrage has also added the following water efficient items in its restrooms:

  • Low-flow urinals (3-tick)
  • Automated taps (3-tick)
  • Dual-flash low capcity flushing cisterns (3-tick)
  • Occupancy sensors for toilets (lighting)

​Marina Barrage has installed sub-metering for water and electricity within its facility to track water leakage, and monitor water and electricity consumption.
