Percentage of Non-residential Buildings in Singapore Not Green Mark Certified and Plans to Engage Building Owners
Ministry of Sustainability and the EnvironmentSpeakers
Summary
This question concerns the percentage of non-residential buildings lacking Green Mark certification and strategies to manage excessive air-conditioning. Er Dr Lee Bee Wah inquired about feedback systems for low temperatures, to which Minister Masagos Zulkifli B M M replied that 50% of non-residential floor area is greened, targeting 80% by 2030. He noted that the Green Mark scheme encourages indoor temperatures of 24 to 26 degrees Celsius and announced Minimum Energy Efficiency Standards for industrial chilled water systems starting in 2020. The Ministry will also work with the Building and Construction Authority to encourage owners and tenants to reduce their energy consumption and carbon footprint. Finally, the Third Green Building Masterplan focuses on changing occupant behavior to ensure sustainable development and meet international climate commitments.

22 Er Dr Lee Bee Wah asked the Minister for the Environment and Water Resources (a) what percentage of non-residential buildings in Singapore are currently not Green Mark certified; (b) whether there is a system for end users and the public to provide feedback on buildings that have their air-conditioning set to temperatures lower than necessary; and (c) how does the Ministry engage these building owners on their building's ambient air temperatures.
Mr Masagos Zulkifli B M M: Buildings contribute up to a quarter of Singapore's carbon emissions. The "greening" of buildings play an important part in ensuring Singapore continues to develop sustainably and meet our international climate change commitments. Singapore is targeting to "green" 80% of our total building gross floor area (GFA) by 2030 and to date, about half of Singapore's non-residential building GFA has been greened to meet minimum sustainability standards.
Today, users of air-conditioning in commercial buildings are encouraged to set their indoor temperatures at around 25 degrees Celsius through voluntary schemes like the BCA Green Mark (GM) scheme. The GM scheme recognises buildings for maintaining indoor temperature in air-conditioned space at 24 to 26 degrees Celsius. Under the scheme, recognition is also given for the installation of energy efficient air-conditioning systems. The latest Third Green Building Masterplan, launched in 2014, also focuses on changing the way building tenants and occupants consume energy.
Aside from commercial buildings, the Government also works closely with industries on cooling efficiency. Starting from 2020, NEA will set Minimum Energy Efficiency Standards (MEES) for chilled water systems in industrial facilities. This will help companies reduce their energy consumption, save on energy costs, and avoid carbon emissions.
To continue our efforts in combating climate change, my Ministry will work with BCA on programmes to encourage owners and tenants of non-residential buildings to reduce energy consumption and lower their carbon footprint.
