Keppel Bay Tower bags Green Mark Platinum building accolade

It’s the first commercial building in Singapore to be awarded as such.

Keppel Bay Tower, owned and operated by Keppel Land, has been certified as a Green Mark Platinum (Zero Energy) building by the Building and Construction Authority (BCA). It is the first commercial building in Singapore to be awarded as such.

“A Green Mark Platinum (Zero Energy) building must, in addition to achieving a low energy use index of less than 115 kWh/m2 per year, also have all of its energy consumption, including plug load, supplied from renewable sources, both on-site and off-site,” said Keppel in a media release.

The energy-efficient technologies pioneered at the Keppel Bay Tower include an air distribution system, a cooling tower water management system, integrated sensor technology to optimise fresh air intake, smart LED lighting solutions, and an intelligent building control system.

“By February 2020, Keppel Land had achieved a reduction of 22.3% in annualised energy consumption of the building, exceeding its initial target of 20%; following the successful pilot, some of these technologies, such as the high-efficiency air distribution system, are currently being replicated to the rest of the building,” added Keppel.

Photovoltaic (PV) panels spanning over 400 m2 will also be installed on the building’s roof space, as well as its six-storey podium block. The PV panel system is expected to generate an energy yield of about 100,000 kWh per annum.

Upon the completion of these initiatives, Keppel Bay Tower’s annualised energy consumption will be less than 115 kWh/m2 per year, a drop of over 30% from its 2017 Green Mark Platinum level and almost 50% less compared to typical office buildings in Singapore, added Keppel.
