Green buildings Ecotown Tampines
Several buildings in Tampines central may soon be retrofitted with a cooling system that is more energy efficient. This can lead to 17 to 18 % reduction in electricity consumption. Known as distributed district cooling, the proposed network for Tampines involves having the existing cooling systems of selected buildings produce chilled water to serve the building and others around it.
The buildings will all be interconnected via insulated pipes that can distribute and circulate the chilled water in a closed loop.Greener system of cooling buildings pave the way for more eco-friendly towns. Sustainable towns and districts are essential for Singapore to meet our sustainability goals under the Singapore Green Plan 2030.
A district cooling system can be likened to a giant air-conditioner that can cool an entire district of buildings rather than just individual ones. Chilled water is generated in a central cooling plant before being piped to various buildings through an underground network to provide air conditioning. Warmer water is then circulated back to the cooling plant, so that they can be chilled again and redistributed to buildings. One area that has implemented a district cooling system is Marina Bay. Designed and operated by SP, the underground system serves 16 developments in the area, including Marina Bay Sands, the Marina Bay Financial Centre, as well as One Raffles Quay. By centralising the production of chilled water, about 25,000 sq m of prime land space was freed up for other uses, as buildings did not have to build their own chiller plant.

A new type of heat-reflective paint will be used on some 130 Housing Board blocks in Tampines, under a pilot project that aims to reduce ambient temperatures by up to 2 degree Celsius.
