Residential buildings are one of the major types of buildings in construction sector. These buildings can beconstructed in harmony with nature rather than just building blocks which consume lot of energy. It is extremelyimportant that the key players associated with the residential industry understand this and make conscious decisionsduring execution. One of the major concern during the construction phase is the use of cement which requires hugeamount of energy for its production. This dependency on cement can be reduced to a great extent by partial replacementof cement with industrial by-products like fly ash and GGBS. A web-based survey questionnaire was developed anddistributed to a list of developers, civil engineers and architects to evaluate the existing trends of these replacements inconcrete in the residential industry of developing belt of Pune city. The survey results indicated that 50% of theresidential project are using M20 grade of concrete and 62.9% of these projects are not using any replacement of cementin concrete. Such 48 ongoing projects from the study area has been selected and a concrete mix for M20 grade with 50%cement replacement with GGBS has been designed for these projects. The estimation of reduction in CO2 emission due toreplacement of 50% cement with GGBS is found to be 14646 tonnes.
