C04 -- Development and validation of ISHRAE Indoor Environmental Quality Standard ✓ Most Recent

This paper represents the journey of India's first-ever IEQ standard (i.e., ISHRAE IEQ Standard: 10001-2019). This standard provides the threshold limits of IEQ parameters by classifying them into three classes covering international and local benchmarking. It also specifies the methodology, including field measurement protocol and specification of monitoring devices for IEQ assessment. The first version of the IEQ standard was reviewed and implemented in the actual buildings. The findings thus obtained from the case study were used to validate the standard. Most of the IEQ parameters showed compliance with the standard except for some of the IAQ parameters, probably due to increased pollution and dust storms in the study location. Also, the unavailability of monitoring instruments recommended in the standard was the major bottleneck in performing the field measurements. The experience gained through the case study and feedback from various stakeholders and global practitioners was utilized to revise the standard. This paper discusses all the improvements made so far in the prevailing version of the standard. These improvements are envisaged to increase the standard's efficacy and applicability in the Indian context. This standard helps evolve the IEQ rating of buildings in India, where most building stocks are yet to be built. See more
