The cooling paint not only efficiently cools surfaces but also reduces carbon emissions associated with the use of air conditioning. This eco-friendly technology marks a milestone on the path to sustainability in the design of livable spaces.
In addition to its innovative operation, this technology has a significant environmental impact as it reduces energy consumption and contributes to the fight against climate change by reducing reliance on conventional air conditioning systems. Formulated with advanced compounds, this paint reflects up to 95.5% of solar energy and emits heat towards the outer space.
Unlike traditional air conditioning systems, its operation does not require electricity, making it an ideal solution for reducing energy dependency in warm climates. Moreover, it can keep surfaces up to 7°C cooler than the ambient temperature, a key feature to combat the global temperature rise and promote energy efficiency in buildings.
The story behind the cooling paint
Behind this innovative technology is Professor Yi Zheng, an expert in radiative heat transfer and founder of the startup Planck Energies.
This project was born at Northeastern University, where Zheng led research efforts to develop sustainable solutions to reduce global energy consumption.
His commitment to the environment and scientific vision led him to create a paint that not only cools surfaces passively but is also self-cleaning, fire-resistant, and environmentally friendly.
Challenges and the path to success
The path was not without challenges. Zheng and his team faced initial difficulties in optimizing the formula to ensure maximum efficiency and durability without compromising the sustainability of the product.
Securing funding was also a major obstacle, but their perseverance eventually attracted support from the university and investors interested in innovative green projects.
Planck Energies, with the university’s support, is currently working on commercializing this technology. The company has already conducted successful tests demonstrating its ability to reduce indoor temperatures by up to 5 degrees Celsius, standing out as a promising solution for warm climates and regions with limited access to electricity.
Zheng and his team’s story reflects a deep commitment to sustainability and the pursuit of practical solutions to address climate change.
Advantages of the cooling paint
The positive impact of this innovation goes beyond cooling. By reducing the need for air conditioning, the cooling paint helps decrease CO₂ emissions. Furthermore, it represents a considerable energy saving, making buildings more efficient and cost-effective in the long term, with significant reductions in electricity bills.
From a social perspective, this green technology can benefit communities in warm regions with limited access to electricity, offering an affordable solution to improve thermal comfort without significant additional costs. Its widespread implementation could transform the quality of life for millions of people while protecting the environment.
The versatility of this technology makes it applicable in residential, commercial, and industrial buildings. Currently, it is used outdoors to optimize passive cooling. It also holds potential in sectors such as transportation and urban infrastructure. These applications reinforce its value in construction sustainability and in industries seeking to reduce their carbon footprint.
