Nowadays, due to the global warming and climate change, many adverse effects and changes are going on in the Environment. Industrialization further worsens the environmental degradation and the air quality. Especially, the construction industry contributes higher level of air pollution emanating from the construction sites. To mitigate this adverse situation, a step towards the green infrastructure may be the best solution. This study was carried out at the Panvel node of Navi Mumbai in the Amity University campus area. The study area was delineated using the Google Earth Pro software. The green roof design and cost estimation was carried out for the main building, new boys’ hostel and new building block at the Amity University campus. Extensive green roof design was proposed for the main building and the new boys’ hostel and intensive green roof design was proposed for the new building of Amity University Mumbai campus. Sedum plant was suggested for the construction of green roof in the main building and the new boys’ hostel and Rosemary shrubs were recommended in the main building. Apart from this, any other shrubs like hibiscus plants or any other flower plant can be used to enhance the aesthetic value. The total runoff reduction was found maximum in the new building roof area and estimated as 5524.81 m3 and the design cost was estimated as Rs.26,73,000 for the main building. The water retained due to green roof will help in reducing the temperature and also improve the air quality in the surrounding area.
