Rating of Indoor Environmental Quality in Systems of Sustainability Assessment of Buildings

Abstract

Indoor environmental quality (IEQ) has an important impact on health and wellbeing of building users. In order to maintain an acceptable IEQ, policies, strategies and guidelines on achieving the required IEQ have been developed. Control and evaluation of indoor air factors is needed for ensuring the sufficient air quality. Impact of emmisions from building materials, furnishings and HVAC systems to indoor air quality should be included in the assessment of indoor environmental quality. In many systems for sustainability assessment of buildings is put a great emphasis on indoor environmental quality. This paper provides an overview of sustainability assessment systems for rating of indoor environmental quality. The criteria included in LEED, BREEAM and other well known systems for assessment of indoor environmental quality are presented. Building environmental assessment system (BEAS) developed for application in Slovakia is also introduced. Worldwide used rating systems were based on the development of BEAS. This is multi-criteria system contained six main fields such as site selection and project planning; building construction; indoor environment; energy performance; water and waste management. System consist from 53 indicators of assessment.

Studying the Indoor Air Pollution Within the Residential Buildings in Egypt: As a Factor of Sustainability

“…However, it dominates the socioeconomic problems and weighting credits. At the same scope, an earlier paper [42] provided an overview of sustainability assessment to rate the IEQ. It stated that "no best tool" is set for assessing sustainability where, Fig.…”

What is the “DNA” of healthy buildings? A critical review and future directions

“…As afore discussed, the industry is not starting from scratch, as different health metrics are addressed in LEED, BREEAM, and DGNB. However, the percentage of human health-related scores varies widely across standards, with studies noting that human health-related scores in BREEAM account for only 15% [ 110 ] and 16% in LEED [ 111 ]. And each certification has its own drawbacks.…”

Climate change mitigation mechanisms for buildings in hot Arid regions (Case study: Tall Buildings of MENA Region)

“…According to studies, the building performance assessment BEAS is widely used more than BREEAM and even the LEED program all over the world. The BEAS system is being rated by 23.5 as a significant weight for its usage all over the world while LEED is being rated by 22 and the BREEAM is being rated by 15 [33].…”

“…The BEAS building performance system in terms of indoor environmental quality has rated the thermal comfort parameter as the most important parameter in the indoor environmental quality. The Thermal comfort parameter has been rated by 16.4 % from a total parameters percentage 23.5% in the BEAS assessment system [33]. Thermal comfort is defined as a subjective evaluation for the occupant's satisfaction of the interior thermal environment.…”
