One involving a new type of paint containing pigments that reflects the sun's heat may go a long way in helping to cool estates. Preliminary studies by the HDB suggest that the paint could reduce ambient temperature by up to 2 deg C when applied to building facades, roofs and pavements....cool paints on the building facade can help reduce the air-conditioning load very significantly

cool paint is a cost-effective way to tackle the urban heat island effect - a phenomenon in which buildings and pavement surfaces release heat into their surroundings, particularly at night.

The Green Towns programme will involve more housing precincts being fitted with an urban water harvesting system that collects, stores and treats rainwater to be recycled for non-potable uses such as irrigation and washing of common areas.

Smart LED lighting will be installed in all common areas in HDB estates. It uses smart sensors to progressively illuminate the user's path in advance, without causing a sudden brightening effect.

Moves to install solar panels in 70 per cent of HDB blocks by 2030 will further reduce energy consumption.

Greenery will be introduced to the top decks of multi-storey carparks, where urban farms, skyrise greenery and community gardens can be housed.
