Abstract: The global energy crisis and water scarcity have brought the threats and challenges of climate change and environmental concerns for developing and developed countries. Especially developing countries have to address the increasing energy and water demands of growing economies. Energy performance and water consumption of a building are key element in order to control and eliminate the threats. Buildings have huge impacts on the environmental development, economy and social development. Buildings are accountable for almost 40% of total energy consumption and greenhouse gasses emissions. The purpose of this quantitative research is to investigate cost optimization of existing residential buildings for sustainability in a composite climate zone, through energy and water efficient strategies in order to address the concept of sustainability for existing built environment. The findings shows there is a strong need for adopting the green retrofitting energy and water efficient strategies where we can conserve total of 691665 KWh energy annually by replacing of conventional electrical fans, exhausts fans with energy efficient ones and geysers with solar water heaters with a payback period of 8 to 15 months, and reduce water usage by 40% by replacing conventional water fixtures with efficient ones but it won’t be financially attractive because the source of water is from tube well inside the campus ground water and is supplied free of cost but it is advised to go for purpose of sustainability and conservation of water for future generation. Finally, it is suggested that application of these strategies are not only cost effective but for sustainability and utilizing of resources.
