Evaluating retrofit strategies for greening existing buildings by energy modelling & data analytics

Design strategies that account for local micro-climatic conditions can reduce the overall energy consumption of buildings over its life. This paper evaluates non-structural retrofit strategies for reducing energy consumption for existing buildings. Based on real-life data on usage statistics of buildings and accounting for local climatic conditions, we validate energy consumption predictions by Sefaira^® building simulation software. A comparative analysis is then performed for various energy conservation scenarios by estimating energy reduction and payback periods. Our analysis shows that various retrofit strategies can lead to reduction in energy consumption upto 60% with a pay back period of about 9 years.
