Low Energy Buildings Design Codes and Guidelines

European Standards

• • CEN TC 156 prEN 15271 Draft - Criteria for indoor environment including thermal, indoor air quality, light and noise. Specifying of classes for environment in buildings: Category A corresponds to high level of expectation (and leads to highest precentage of satisfied occupants in respect to indoor environment), category B a medium level of expectation and category C to a moderate level of expectation.
