Indoor air quality audit and certification of buildings in Portugal

The transposition of the European Directive ٢٠٠٢/٩١/EC into Portuguese law, on April ٢٠٠٦, comprised the development of IAQ requirements, and the creation of an IAQ certification process which goes together with the energy certification of large service buildings, both part of the National System of Energy and Indoor Air Quality Certification of Buildings (SCE). The IAQ requirements by which SCE is put in practice were defined in the updated (٢٠٠٦) version of the national law known as Regulation of the Energy Heating and Cooling Systems in Buildings (RSECE). In addition to the IAQ methodologies set by RSECE, supplementary methodologies, guidelines and recommendations were published in technical note NT-SCE-٠٢, ٢٠٠٩. This technical note ensure minimum quality audit standards and procedures would be set and that all qualified experts would follow similar or equivalent methodologies during the IAQ audits and reporting.
