Abstract


The Building industry is a major energy consuming sector in India. The NMSH states, building energy consumption has increased from 14% in 1970 to 33 % in 2004-2005. This sector is also one of the fastest growing sector. A report published by the GBPN states that about 75% of the buildings expected to exist in India in 2030 have not been built. Projected increase in floor area of building sector will also increase the demand for energy required during construction, occupancy and demolition and increase the Carbon Foot-Print (CFP) of building sector.

The main objective of the research is to identify the potential of Low Emission Development strategies (LEDs) in reduction of CFP of the construction project. The analysis has been prepared after studying an ongoing residential project (built-up area: 2 lac sq.mt) in Mumbai. The study analysed each phase of the project; Demolition, Construction and Occupancy. Partial Life Cycle Approach is selected. Detailed calculation model is prepared using a ‘Bottom-up’ approach defined in IPCC guidelines. India specific emission factors for electricity, transportation and construction material inventory. For the material inventory ‘Cradle-to-Gate’ approached is used. The potential of LEDs vs. conventional practises is examined. The analysis proves that adopted LEDs significantly reduce the CFP of the residential project in each phase: 75% reduction in demolition phase, 18% reduction in construction phase, 10% reduction in occupancy phase. The study provides guidelines for stakeholders to take informed decisions on reducing carbon emissions and ultimately reduce the climate change impact of the building.
