Switch2Save promises to save a lot of energy in areas with high outdoor temperature (i.e. the southern area) by reducing the use of air conditioning systems or completely eliminating the demand for air conditioning systems. Dr. John Fahlteich, coordinator of the Switch2Save project and head of the research team of Fraunhofer FEP, explained that in the warm regions of Europe, the cooling and heating energy demand of modern buildings can be reduced by as much as 70%. In the colder northern regions, the cost savings are not large, but the system can also be used here as anti glare protection to prevent direct sunlight.
