Engineers at Berkeley Laboratory have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it's hot, the material reflects sunlight and heat, but this radiative cooling is automatically turned off in winter, reducing energy use for heating and cooling.
The air conditioning roof is a technology that has been seen time and time again in the air conditioning sector. The novelty of TARC is that, in addition to cooling the interior of your house, it is also capable of heating it.
TARC ( Temperature-Adaptive Radiative Phone Number List Coating ) is a thermal coating for home roofs developed by scientists at the University of California, Berkeley.
Its strength lies in its ability to regulate itself automatically based on the outside temperature , without the need for energy.
This air conditioning system is designed to reduce energy consumption in heating and cooling and maintain optimal thermal comfort inside.
What is thermal coating for homes.
Thermal coating for homes is a type of material that is used in the construction of buildings to improve their thermal insulation . Thermal coating is placed on the walls, ceiling and floor of the home to help retain heat inside during the winter months and keep the building cool in the summer months. This can help reduce heating and cooling costs and improve resident comfort. Additionally, thermal cladding can also help reduce the amount of energy needed to heat or cool the building, making it a sustainable and energy-efficient option.
How does it work.
Roofs with cooling properties have surfaces that reflect sunlight and some of the heat from the air to limit heat absorption. Although this is useful in summer, it still works in winter, cooling the house and increasing the need for heating.
To solve this problem, the Berkeley researchers used a unique material: vanadium dioxide .
This metal, unlike most metals, acts as an electrical conductor without conducting heat or absorbing infrared radiation. However, when the temperature drops below 67°C, the material properties change. It then becomes capable of conducting heat. This discovery gave rise to TARC technology . The researchers "doped," as they call it, vanadium dioxide by replacing a small part of it with tungsten. Doping makes it possible to reduce the threshold from 67 °C to 25 °C, the temperature at which the material conducts heat.

According to measurements made by the researchers, the material reflects an average of 75% of sunlight . However, the reflected amount increases up to 90% at high outdoor temperatures. This promotes heat loss, keeping the interior of the house cool. On the other hand, in cold weather the amount of reflected light is only 20%, which helps retain heat.
