This paper demonstrates the implementation methodology for India’s first IEQ standard (ISHRAE Standard-10001:2016) in actual buildings. The IEQ standard encompasses the definitions of IEQ elements (i.e. thermal comfort, indoor air quality, visual comfort, and acoustic comfort), threshold values of IEQ parameters determining these elements, specifications of measuring instruments, and methodology to undertake IEQ assessments in buildings. The pilot study identified the preliminary findings to understand and evaluate the practical implementation of the IEQ standard through field measurements. The quantitative measurements of IEQ elements were carried out in two academic buildings in the Jaipur climate (warm and humid as well as hot and dry and cold). The occupant’s subjective evaluation was made through a questionnaire survey administrated concurrently with physical measurements of IEQ parameters. This study provides the clarity of method for taking IEQ measurements and comments on the availability of instruments and their specifications as recommended by the standard.
Practical application: The present study is the practical implementation of the IEQ standard in buildings. This standard provides the threshold limits of IEQ parameters by classifying them into three classes covering international and local benchmarking. The standard also specifies the research methodology including field measurement protocol and specification of monitoring devices for IEQ assessment. This standard is useful for evolving IEQ rating of buildings in India where the majority of the building stocks are yet to be built.
