CALUWIN – The energy-saving program
With the calculation program CALUWIN for architects and engineers as well as partners and advisers, you can quickly and easily calculate potential energy savings by using Swisspacer.
This allows the Uw value for a wide range of window constructions to be determined simply and precisely. CALUWIN also offers a simulation tool for pressure-equalised insulating glass units.
The tool is also available as an app for iOS and Android devices in the corresponding app stores.
