The EcoCampus initiative uses the NTU campus and the neighbouring CleanTech Park as ‘living laboratories’ for RD&D. The NTU Yunnan Garden campus spans across 200 hectares and has more than 150 buildings. Apart from academic (lecture theatres, laboratories) and office buildings, residential buildings, dormitories and commercial outlets add to the diversity of building typologies on campus. With 12,000 students and 600 staff living on the campus, the campus can be considered a mini-city with a total (resident and transient) population of about 40,000 people. There are a few new buildings coming up on the campus that offers opportunities to integrate innovative technologies right from the design and planning stage.
The overall campus energy consumption is about 200 million kWh of electricity, which is the only form of energy used on the campus. This electricity is largely drawn from the Singapore grid and the recent installation of 5,000 kWp of solar PV generation would contribute to about 3-5% of the total electricity consumption on the campus. As is true for most tropical climate buildings, air-conditioning is the largest (more than 50%) energy use on the campus. Air-conditioning is provided on the campus by 7 mini-district cooling plants consisting mainly of the chiller and chilled water distribution network that server one or more buildings.
The CleanTech Park, is a 50 hectares’ site located next to the NTU Campus and is Singapore’s first eco-business park developed by JTC Corporation (a public-sector land developer in Singapore). With a plan to house up to 15 buildings, it currently has two buildings that support the operations of CleanTech companies and research entities such as DHI, Toray, NTU, NUS, A-Star, Diamond Energy, Renesola, etc.
As a new development the CleanTech Park, aspires to be at the forefront of test-bedding and offering spaces for early adoption of technology and solutions. ERI@N has been involved in the design of the CleanTech Two building, which achieves the highest rating for green building certification in Singapore (viz. GreenMark Platinum) and at the same time incorporates the latest technology innovations such as the liquid desiccant-based cooling system with solar thermal heat. The CleanTech Park actively solicits test-bedding opportunities with a view to implement the technologies and solutions at other JTC sites throughout Singapore. NTU Campus and CleanTech Park are part of the Jurong Innovation District (JID) that is a brownfield site to develop as a cutting-edge and futuristic industrial park.
