Abstract
With the growing economy of India, banking sector growth has led to installation of thousands of Automatic Teller Machines (ATMs) throughout the country. ATMs provide 24 × 7 services as well as operate at low-temperature ranges of cooling, hence have high operating energy costs. Insulating an ATM’s envelope is not a prevalent technique in India. In the present study, an effort has been made to determine the optimum insulation thickness for three different insulation materials for the typical ATM envelope in four different climatic zones of India. Life cycle savings and payback periods for various insulation materials are also evaluated. Further, these optimally insulated ATM envelopes can be integrated with grid connected rooftop solar PV systems. The energy saving and emissions reduction potential due to these two interventions have been estimated on the national basis. Altogether in the four selected climate zones, energy saving of 17% - 30% provides the annual economic benefit of Indian National Rupees (Rs.) 3570 million with annual carbon reduction potential of about 0.60 million tCO2. From this study, it is observed that properly insulated ATMs integrated with rooftop solar PV systems, can significantly reduce the energy costs as well as carbon emissions in India’s context.
Highlights
Rapid population growth, urbanization and quality of life improvement in India have led to a substantial increase in energy demand outstripping the supply

Summary
Urbanization and quality of life improvement in India have led to a substantial increase in energy demand outstripping the supply. Optimum insulation thickness (OIT), net energy cost savings was estimated and energy consumption of residential buildings was forecasted for different degree-day regions of Turkey [6] [7] [8] [9] [10]. Reduce the heat gain and losses in building by applying OIT of thermal insulation as well as inter-relate the OIT of insulation materials for various structure wall and their orientations using an implicit finite-difference method under dynamic thermal conditions for Turkey [19] [20] [21]. On the basis of life cycle energy consumption, OIT of EPS insulation was obtained for residential buildings in India [30] [31].
