Energy Efficiency is a key for sustainable infrastructure development. The exponential growth in the infrastructural development is expected to reach 10,835.6 billion USD by 2023. To cater the power needs, energy efficiency in buildings is prime factor needed to be taken care off. The vision of ESCO is to provide energy efficient smart building plans for new and the existing buildings. Energy efficient buildings include efficient lightings, fans, Heating, Ventilation and Air-Conditioning (HVAC) according to American Society for Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards
