Abstract

Objectives: To carryout green audit in existing educational complex and provide suggestions for green retrofitting using IGBC rating system. Methods/Analysis: The green building movement has gained tremendous momentum during the past 3-4 years. The present building stock is substantively huge and denotes one of the largest chances to decrease energy waste and control air contamination and worldwide warming. This paper presents detailed green audit carried out for an existing educational complex along with the recommendation for Green Retrofitting of the building. The parameters considered are site and facility management, Energy consumption, Water consumption, indoor environmental quality and Innovation. The data has been collected for the green retrofitting of existing educational complex and the measures and cost analysis has been carried out for implementation of suggested measures for the green retrofitting. Also the payback period of the investments has been calculated. The green building rating as per IGBC rating system has been evaluated for the educational building considering its present status and also after implementation of suggestions for green retrofitting for the building. Findings: The building gains 35 points at present and 76 points after implementation of suggested measures for green retrofitting. Payback period for energy retrofitting is in the range of 3 to 5 years. Applications/Improvement: Green retrofitting of the considered building will have benefits for the owner as well as users in the form of more comfortable and hygienic environment. The exercise carried out in this work can be applied to any other existing buildings to achieve green certification. The present work will serve as basis for implementation of ‘Green Retrofitting’ to existing buildings wherein the findings of this work will motivate stakeholders to carryout Green Retrofitting.
