“…Rather than setting arbitrary quality levels, the TAIL rating scheme refers to the quality levels defined by Standard EN 16798-1 [17], so they can be assumed to be widely accepted and used; arbitrary credits are used in many certification schemes [44], and other methods to rate IEQ [32,37,38]. The principle of the approach is that the quality level of all components contributing to the overall rating of IEQ must be high if the indoor environmental quality is to be regarded as high.…”

“…Mui et al [33] developed an IEQ index consisting of five indicators: air temperature, relative humidity, CO 2 concentration, horizontal illumination level, and sound pressure level; the focus was on air-conditioned buildings. Finally, Larsen et al [32] proposed IEQ-Compass, a method for assessing IEQ during the energy renovation of dwellings. IEQ-Compass is an asset rating as it provides a method for assessing the quality of the indoor environment at the design stage that would result from design decisions that would achieve energy savings, so no actual verification and measurements can be made dur-ing its use, although a check is made by asking building occupants to rate the parameters defining IEQ.…”

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.

“…The early research of IEQ focused on a single aspect such as thermal comfort and ventilation to set standards and guidelines, and later specific IEQ factors and their association with overall comfort or satisfaction have been explored to determine more influential factors in the built environment. Although indoor environment encompasses a range of components including temperature, humidity, indoor air quality (IAQ), lighting, ventilation, noise and crowdedness of workspace (Clements-Croome & Baizhan, 2000), IEQ is largely characterized by four environmental categories including thermal comfort, IAQ, lighting and acoustics (Larsen et al, 2020) without taking into account the spatial comfort of the occupants in literature. It is understood that the four environmental categories are more fundamentally affected by building design and technical solutions such as building envelope and services.…”

“…Indoor environmental quality (IEQ) is the combination of indoor environment components that interact with users of the environment. It is largely characterized by four environmental categories including thermal comfort, indoor air quality (IAQ), lighting and acoustics (Larsen et al, 2020). Thermal comfort and IAQ have been identified as the two most important aspects of IEQ that receive considerable attention by building designers and occupants (Huizenga et al, 2006;Humphreys, 2005), demonstrating that satisfaction with air quality and thermal comfort is generally more important than satisfaction with the level of lighting or noise.…”

This paper reports the results of a comprehensive indoor environmental quality (IEQ) evaluation conducted in seven office buildings at an Australian university. A mix of objective and subjective assessments was carried out and a total of 519 staff participated in the survey from various non-academic departments. Three types of buildings were included in this study: 'Heritage listed' (c.1880-1890s), 'Conventional' (c.1960 and 'Modern' (post 2000) office buildings. Although the measured IEQ conditions were relatively good with no significant fluctuation across the selected buildings, the discrepancy between objective IEQ data and subjective occupant evaluations was noted. The Modern building type designed with fully double-glazed façades showed the highest levels of overall comfort and satisfaction and perceived productivity, whereas the Conventional building type constructed during the late 20th-century period, notable for deep floor plates, had the lowest. The heritage listed type buildings had lower window to wall ratios, yet displayed improved occupant satisfaction across all IEQ areas over the conventional type buildings. The results support that building renovation and regular maintenance can improve occupant comfort and satisfaction within offices. The findings could be useful for property managers looking for strategies to improve the performance of their building stock.

This study investigates the determining parameters of thermal comfort of office in an arid hot-arid environment of Bechar, located in the northwestern region of Algeria, in which the vertical walls of the room and the roof are subjected to solar irradiations and the floor is considered to be adiabatic. The solar flux is calculated by the ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) method. The predicted results are validated against the experimental results of the meteorological station of the ENERGARID research laboratory at the University of Bechar (Algeria). The characteristics of the ambient air flow are performed by using the computational fluid dynamics (CFD) software (Fluent). The flow fields, thermal fields, and humidity are investigated. An elaborated computer program (with Delphi language) is utilized to evaluate the temperature–humidity coupling as the most essential factors of the thermal comfort. A significant impact of dynamic temperatures and humidity on thermal comfort has been observed, especially in this hot-arid environment. Besides, a considerable effect of the flow velocity has been remarked. From the obtained results and to provide the best thermal comfort in such arid regions, the range of air velocity inside the building is recommended to be between 0.2 m·s−1 and 0.3 m·s−1.
