How to keep industrial buildings cool? Factories can get extremely hot during the summer months, making it difficult for workers to perform their jobs efficiently. Fortunately, there are several ways to keep industrial buildings cool and comfortable.
1/ Solar Paint
French company SOLAR PAINT has developed SOLARCOAT®, a reflective paint that is able to cool the interior of buildings. The process consists of coating the roofs with this white and reflective paint. This paint has a solar reflection rate of over 92%, which reduces the temperature inside buildings by an average of 5°C and thus, limits the need for air conditioning in the summer. In the end, the solution helps reduce the energy bill.
2/ Air Conditioning Without Air Conditioning
Italian company SINTRA has been manufacturing eco-friendly air treatment solutions for 30 years with the objective of making buildings energy self-sufficient. They came up with an HVAC system that replaces artificial air conditioning with free, natural, and ecological air conditioning.

3/ Thermoacoustic Pumps
French startup Equium sits at the forefront of the new wave of startups applying thermoacoustics to heat pumps. The company recently unveiled a new heat pump core that can produce about 3 to 4 kW of heat for every kW of power drawn into the system. The device makes it possible to build refrigerant-free heat pumps capable of heating water up to 80° Celsius while also reaching lower temperatures for air cooling.
