ABSTRACT
Over the last few decades, advances in materials, testing procedures and novel environmental challenges have unquestionably forced regulation improvements and international standards development. The international standards for thermal comfort assessment should be valid in terms of the generally accepted principles whose main goal is to avoid any potential health risks imposed on humans. All of the standards are used in a complementary way, providing requirements and criteria for acceptable thermal comfort conditions. The basic criteria behind any internationally accepted standard is to produce a generally accepted, objective, reliable, safe and recognized methodology to be used by both trained professionals, scholars and other interested parties. The standards concerning the thermal comfort provide authenticated and systematic knowledge produced by experts. The ISO standards are revised every five years in order to be fully compliant to current technological advancements. If significant developments have taken place, the new standard will be proposed, which should provide the best internationally agreed method on the subject involved.
