|Energy and water are the basic resources that support economic as well as social development. Concerns are growing over the effects of rising carbon dioxide emissions from energy consumption and water shortage problems. Hence developments that can achieve “low carbon” and “water conservation” outcomes are becoming socially and politically desirable. Energy and water are closely related. Energy production and utilization processes require the use of water. Similarly, water acquisition, allocation, and utilization stages are accompanied by energy consumption. Benchmarking of energy and water footprint has been made for residential building in Bangalore city in climate zone of savanna climate with distinct wet and dry seasons. The electric and water bills of the building similar to the case studies has been collected for duration of 1 year for calculation of carbon footprint, water footprint of the building system. The different footprint diagram viz., carbon footprint, water footprint, embodied energy footprint and building footprint are presented. Embodied energy has been used for evaluation of carbon footprint. Embodied energy for the 2 building topologies chosen namely:-Case study 1, case study 2 are respectively.
The carbon footprint for 2 buildings topologies chosen namely:-
Case study 1, case study 2 are respectively.
The water footprint for 2 buildings topologies chosen namely:-
Case study 1,case study 2 are respectively.
When it comes to the total amount of footprint, the 2BHK & 3B individual houses (kammanahalli houses) consumes maximum energy and consumes more water.
