The EPBD mandates Member States to support energy performance upgrades of existing buildings for a healthier indoor environment. The TAIL rating scheme was developed to address the lack of a widely accepted method for rating overall IEQ. By standardizing the rating of thermal, acoustic, indoor air, and luminous environments, the scheme provides a comprehensive assessment of IEQ levels.
To avoid health risks and discomfort, the European Energy Performance for Building Directive (EPBD) mandates that Member States should support energy performance upgrades of existing buildings that contribute to achieving a healthy indoor environment. There is, however, no widely accepted method for rating the overall level of indoor environmental quality (IEQ), although several different approaches are proposed by standards, guidelines, and certification schemes. To fill this void, a new classification rating scheme called TAIL was developed to rate IEQ in offices and hotels undergoing deep energy renovation during their normal use; the scheme is a part of the energy certification method developed by the EU ALDREN project. The TAIL scheme standardizes rating of the quality of the thermal (T) environment, acoustic (A) environment, indoor air (I), and luminous (L) environment, and by using these ratings, it provides a rating of the overall level of IEQ. Twelve parameters are rated by measurements, modelling, and observation to provide the input to the overall rating of IEQ. Their quality levels are determined primarily using Standard EN-16798-1 and World Health Organization (WHO) air quality guidelines and are expressed by colours and Roman numerals to improve communication. The TAIL rating was shown to discriminate IEQ levels when its feasibility was examined in eleven buildings across Europe to provide support for its applicability and input for further modifications. Opportunities for using the scheme in other types of buildings and for its further development and application are discussed. (c) 2021 Elsevier B.V. All rights reserved.
