HVAC usually represents the largest constituent of any building equipment and covers about 30%-60% of total energy consumption. There is tremendous energy saving potential in HVAC systems, brought about by age-related deterioration of the system, improper operations or control, inadequate maintenance, system usaage stresses etc.

ESIPL analyses key parameters impacting the performance of the HVAC system and invests in making the system perform efficiently. Interventions can start from maintenance of condenser coils to replacement of old chillers with new energy efficient chillers, which generates savings 5%-50% of energy consumption of the system.
