Abstract:
Green building is the one which uses less water, optimizes energy efficiency, conserves natural resources generate less waste and provides healthier spaces for occupants as compared to conventional buildings (U.S. Environmental Protection Agency 2008). The study entitled, “A comparative study on green and conventional buildings” was conducted by covering the two districts i.e. Gurgaon and Panchkula. Four green and four conventional buildings were selected purposively for comparing the IEQ level in both seasons winter as well as summer. The floors were divided into five zones and data were collected from all the floors of the building. Considering all the IEQ data of green and conventional buildings, green buildings were far better than that of conventional buildings in all the IEQ aspects except the humidity level which was found out be higher in green building 1 than the conventional buildings 1 (1.91%) and the noise level in conventional building was less than that of green building 1 during winter afternoon (11.66 dB), evening (1.34 dB) and afternoon of summer as well (5.6 dB).
