Dear Mr. Chong

RE: Request for Proposals

This letter is to inform you of our acknowledgement and response to your letter of authorization. We are pleased to present you with the following proposal for upgrading older generation public housing buildings into green buildings. This will be in line with Building and Construction Authority’s (BCA) goal of having at least 80% of buildings in Singapore to be green by 2030.

In 2005, BCA introduced the Green Mark scheme to encourage new buildings in Singapore to be sustainable and eco-friendly. In 2006, BCA released the Green Building Masterplan to motivate industry stakeholders to embrace green buildings. While these initiatives are critical and necessary (BCA has since released Green Building Masterplan 3 in 2014), we must not forget the many HDB flats built before 2005.

As of 31 March 2005, there were 879,556 units, and taking an average of 103 units per block according to teoalida.com, that would equate to 8,540 HDB blocks built before Green Marks existed. We must not forget about these buildings as they form a large percentage of all buildings in Singapore. If BCA wants to have 80% of buildings in Singapore to be green by 2030, we need to upgrade these old generation buildings with new green technology.

We are proposing the use of smart meters in individual homes of these mature HDB estates. These smart meters provide real time update on the amount of electricity or water being used. It is a good way to influence the residents to reduce their utility consumption.

We believe that education of the public over introduction of new technologies will have a greater impact on Singapore in terms of going green because of how wasteful Singaporeans can be. We are targeting the HDB flats because 76.3% of all dwelling units in Singapore are HDBs, which allows us to reach more of the public.

Yours Sincerely,

Siok Xue Yuan
