In Dunskajá Streda, Slovakia, around 14,000 m² of roof surface of the elevator manufacturer Schindler výtahy a eskalátory a.s. was coated with ThermoActive in 2019. The executing partner was the company HOFER SK, s.r.o., 01001 Žilina.
High temperatures in the production halls due to heating of the roofs. The roof temperature outside was 51.4°C in a comparative measurement.
Passive cooling through a high-tech coating based on reflective membrane technology: ThermoActive. This passive cooling is achieved by the extremely high sunlight reflection and by evaporation processes. Sunlight is reflected up to a value of 91.4% (total solar reflectance, TSR).
After coating with ThermoActive roof paint, the roof temperature outside, measured under identical conditions, was only 28.2°C. Thus the temperature could be lowered by 23.2°C. This temperature reduction can save energy consumption for active cooling of the production halls. Less energy consumption means a reduction in CO2 emissions. This makes an active contribution to climate protection.
