Everyone might be aware of the fact that earth is warming at an unprecedented rate. And as per many scientists- we ‘Humans’ are responsible for enhancing this overall global warming trend. The tremendous rise in temperature is not only experienced in one country or even one continent but all across the world. One of the reasons is a rise in the use of air conditioners during hot summer months, which not only increases the rate of energy consumption but also elevates the levels of CO2 in the atmosphere. Refrigerants in the ACs absorb heat from inside a room and release back it into the surroundings, which further escalate the environmental temperature.
To protect buildings and urban structures from this excessive solar radiation, a Dutch Architecture firm- UNStudio has come up with an ultra-durable white paint. The company has developed this “Coolest paint” in collaboration with Monopol Colors- a Switzerland based paint company- to lower urban heat island effect. It is a lifelong and ultra-durable product with exceptional weatherability and high corrosion resistance up to 75 per cent.
“It is undisputed that our cities are rapidly getting hotter, so we have to ask ourselves how we can stop this trend. On the one hand, ’The Coolest White’ makes buildings more resilient, and on the other hand, it can drastically reduce the urban heat load,” says Ben van Berkel, founder and principal architect of UNStudio.

The dark-coloured materials that are used to construct the buildings in our cities are one of the leading causes of heat accumulation in urban areas. While darker materials absorb up to 95% of the sun’s rays and release them straight back into the atmosphere, this value can be reduced to 25% with a normal white surface. Now, with ‘The Coolest White’, it is possible to reduce absorption and emission to 12%. The white paint protects against UV rays as well as abrasion and thus assists in retaining colour and gloss finishes of the building facade. It is also suitable for metallic facades such as aluminium, steel or fibreglass structures because of its strength which is 2.5 times more than its standard polyester-based counterparts.
“On the one hand, heat from buildings is released into the environment, while at the same time the necessary cooling of the building increases energy consumption. In view of global warming, this is a vicious cycle we have to break out of as a matter of urgency. When you think that, after only the next 30 years, 68% of the world’s population will be living in towns and cities, it is certainly not wrong to tackle this issue very specifically in the urban environment, “says Lionel Schlessinger, Owner and Managing Director of MonopolColors:

The Coolest White is a coating system with very high total solar reflectance (TSR). TSR is the power of resistance of a coating to the effects of sunlight. It is based on fluoropolymer technology.
