Deliverables

Improved testing methodology and characterisation procedures for long-term performance assessment of EC/TC windows

Report on refined and improved characterisation metrology and test methodology to determine long term performance of energy smart windows to be made available to public as open access white paper or journal article

Specification sheets for energy smart IGUs

Requirements from building design, comfort, safety regulations and building energy consumption directives will be translated to a technical specification sheet (report) including targeted transmission spectrum, color rendering index, weight, mounting aspects, consequences for materials use, etc.

Specifications for virtual demonstration cases

Report with a definition and specification of representative virtual buildings for which the Energy Saving Potential of Switch2Save Technology will be modelled, calculated and optimised through active switching protocols.
