Singapore, 10th February 2011
Today I read an article in the newspaper that Singapore has embarked on a program to generate carbon credits. The program consists of replacing current fluorescent lights in housing flats (HDB) to LED equivalents. It is claimed that by replacing the fluorescents with LED in about 2000 flats island wide a saving of S$ 5 million (about U$ 3.8 Mio) a year will be achieved for the town councils. A total of 340,000 lighting points in corridors and stairways have been identified for the replacement. According to the article LED uses 60% less energy, produces less heat and lasts 6 times longer. The cost of installating LED is stated to be 3 times that of a fluorescent point. Interestingly the article focuses only on the cost and energy saving, implying that the replacement produces the same quality of light. I have my reservations…
Under the Kyoto protocol developed countries like Singapore can register their energy saving efforts with the United Nations who administers this. This projects is expected to yield about S$ 250,000 worth of carbon credits a year. A carbon credit can be used to offset excess greenhouse gas production (most developed nations have maximum emission targets as agreed under the Kyoto protocol) or can be sold on the global carbon market. Currently a certified carbon credit is worth about Euro $10-15. One carbon credit allows the holder to emit the equivalent of one ton of carbon dioxide.
The interesting twist in this project is that the winning contractor will have to foot the whole cost of installation which is estimated to be about S$ 22 million. In return however they will share in the energy savings of S$ 5 million a year.
Singapore’s HDB flats are todays pick for Light Watch. Though I have yet to see if the picture is as “rosy” as it is been presented in todays news article, the initiative is interesting and certainly worth looking out for. The Housing Development Board of Singapore has always been in the forefront when it comes to applying new technology.
