Too hot at home? HDB’s heat-reflective paint initiative might be a saviour

Let’s face it — living in Singapore means dealing with hot and humid weather all year round. If you’ve ever felt like your HDB flat turns into an oven during the afternoon, you’re not alone. This collective distress is one of the reasons why HDB is rolling out heat-reflective paint to all estates by 2030. The special coating paint is designed to keep flats cooler, cut down on aircon usage, and make life a little more comfortable.

Here’s everything you need to know about the HDB’s heat reflective paint initiative:

A test run in Tampines

Before going all-in on the nationwide rollout, HDB tested heat-reflective paint in Tampines to see if it actually made a difference. The trial started in October 2022, with the special paint applied to 88 out of 130 blocks. The rest are set to be completed by the end of this year.

So, what were the results? The paint helped bring down ambient temperatures by up to 2°C. That might not sound like a lot, but in Singapore’s heat, every degree matters. On top of that, residents in the painted blocks noticed lower electricity bills because their homes didn’t trap as much heat — meaning less reliance on air conditioning. With results like these, it’s no surprise HDB is pushing forward with the island-wide rollout.

How does heat-reflective paint work?

This isn’t just any regular wall paint. Cool-coating paint is packed with special pigments that bounce off a good chunk of the sun’s infrared radiation. In simple terms, it stops your building from absorbing too much heat. That means exterior walls stay cooler, and less heat seeps indoors. The result? A home that doesn’t feel like a sauna by midday.

The technology behind this has been around for a while, but HDB is taking it to the next level by applying it across entire estates. The Tampines trial proved that it works, and now, the rest of Singapore will get to enjoy the benefits too.

What’s in it for HDB residents?

Senior Minister of State for National Development Tan Kiat How said on Feb 3 that scaling up this heat-reflective paint initiative to all existing estates will cost the Government an additional S$60 million. Yes, that’s a pretty huge amount of money, but anyway, here’s what you can look forward to:

• A more comfortable home: Lower indoor temperatures mean you won’t be sweating just by sitting in your living room. This is especially great for young kids, the elderly, and anyone who struggles with the heat.
• Savings on electricity: A cooler home means you won’t need to blast the aircon as often, hence the lower electricity bills. In other words, the U-Save rebates under the GST Voucher scheme can stretch even further for you.
• Eco-friendly benefits: Less aircon usage also means less energy consumption, which in turn reduces carbon emissions. If more homes can stay cool without excessive energy use, the collective impact on the environment will be significant. It’s a win for your wallet and for the planet!
• Long-lasting protection: Heat-reflective paint isn’t just for show — it’s durable and designed to keep your home cool for years before it needs a fresh coat. The cool coating properties can last between 5 to 10 years.

A greener future for HDB towns

The heat-reflective paint initiative isn’t just about keeping your flat cool. It’s part of HDB’s 10-year Green Towns Programme, which aims to make public housing more eco-friendly and sustainable. The programme focuses on three key areas: cutting energy consumption, recycling rainwater, and cooling down HDB towns.

By rolling out heat-reflective coatings across all HDB estates, this initiative directly supports the programme’s goal of reducing ambient temperatures. Cooler homes mean less reliance on air conditioning, which in turn lowers overall electricity demand and carbon emissions.

And it doesn’t stop at paint. The Green Towns Programme also includes other cooling solutions, such as increasing greenery on rooftops and installing solar panels to power common areas. All these efforts work together to create a more sustainable and comfortable living environment for everyone.

With global temperatures rising, solutions like these will play a huge role in making urban living more bearable. The best part? You don’t really have to do anything — just enjoy a cooler home and lower bills.
