During the writing of this report, the European Commission was drafting an ecodesign regulation to set minimum energy performance requirements (MEPS) for professional (commercial service) cabinets. This report outlines the numerical approach CLASP developed for normalizing professional cabinet performance data, taking into account differences in volume calculation methods and measurement methods (ambient temperature, cabinet internal temperature, door
opening protocol, period of energy measurement and energy consumed by auxiliary features such as
defrost, circulation fans, etc.). It describes the proposed methodology developed to make all professional cabinet performance data comparable on a fair basis.
