S$8.3m in grants awarded to improve building energy efficiency

The scheme, first introduced in September last year, aims to support the development of energy efficient and cost-effective technologies and solutions for buildings in the tropics.

SINGAPORE: In a bid to improve building energy efficiency, researchers from the National University of Singapore (NUS), Nanyang Technological University (NTU) and Ngee Ann Polytechnic were awarded S$8.3 million in grants by the Building and Construction Authority (BCA).

Under the Building Energy Efficiency Grant Call, the public and private sectors were encouraged to collaborate and develop innovative technologies and solutions in the areas of Air-Conditioning and Mechanical Ventilation (ACMV), and Building Management and Information Systems (BMIS) for building retrofits in the tropics that can be adopted in five years’ time, BCA said in a press release issued on Wednesday (July 30).

The scheme, first introduced in September last year, aims to support the development of energy efficient and cost-effective technologies and solutions for buildings in the tropics.

While ACMV systems take up 40 to 60 per cent of energy used in a typical air-conditioned building, there is a need for technology that can effectively remove water from the air by using less energy that will greatly improve the efficiency of the air-conditioning system, BCA said.

It also noted the need to develop cost-effective solutions so building owners and developers will adopt the new technologies.

Meanwhile, a grant recipient from NUS, Dr Lee Poh Seng, will be collaborating with Daikin Air-Conditioning and four other SMEs to develop a new air-conditioning system that integrates a “novel oblique fin technology into a small capacity air-conditioning system, which can significantly enhance the air side-heat transfer”.

The new research project will raise “energy efficiency of the air conditioning system potentially by as much as 30 to 40 per cent”, said Dr Lee.

“More efficient buildings mean better use of resources,” said Dr John Keung, CEO of BCA. “Low Energy High-rise Buildings in the Tropics” will be possible in Singapore if researchers are provided with the “right support and environment”, he added.
