Abstract: There has been an increased interest in sustainability in recent times and both business organizations as well as consumers have shown a rising concern for environmental issues. Construction industry in particular has been criticized for its contribution to environmental degradation. The study is based on a questionnaire survey of 100 customers in Delhi and their views regarding sustainability issues in residential real estate was analyzed to determine their preferences and analyze their views regarding the benefits that LEED certified sustainable residential real estate provides. Green construction projects have been found to be reducing carbon emissions , managing waste , use of cleaner fuels , low electricity bills , better quality of air etc. There is improved quality of lives and comfort for the occupants on account of the fact that there is better ventilation and good air quality. Based on the findings it could well be said that there seems to be a lack of awareness among people about the various certification schemes but the consumers have shown a growing interest in purchasing residential units that offer sustainable attributes. Environmental benefits have been perceived to be the strongest .
