Indoor environmental quality rating using the TAIL scheme

The TAIL scheme was developed to rate the indoor environmental quality (IEQ) in buildings. The scheme was developed to assure that occupants' health and well-being are not compromised during deep energy renovation (DER) of buildings but can also be used in other contexts. TAIL combines quality of Thermal, Acoustic and Luminous environment and Indoor air quality to determine the overall quality of the indoor environment. The rating is based on the levels of twelve parameters characterizing IEQ, which are measured, modeled, or inspected in actual buildings. To allow the prediction of TAIL parameters during design, a method was developed called PredicTAIL. Both TAIL and PredicTAIL allow evaluation of IEQ during design and operation. The feasibility of TAIL and PredicTAIL was examined in hotel and office buildings and showed sufficient discrimination power concerning the IEQ in these buildings.
