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.
Heat Pumps are the most efficient way to generate hot water in the range of 40-60°C. Most hotels, hospitals and manufacturing locations use electric or fuel-based boilers or hot water generators. The savings can range between 50%-75% of current energy spend.
Feedback and algorithmic Controls are a valuable tool in delivering energy conservation strategies. Wasteful running of the most energy efficient system is still detrimental to energy conservation goals. Automation builds logic for system usage and eliminates human errors associated with manual intervention.
ESIPL designs hardware-agnostic logic on the basis of its operational expertise and implements energy saving strategies without compromising comfort level of the occupants. The savings can range from 2%-8% of total energy consumption of the facility.
Motors are ubiqutous across all facilities across the globe. They are often the most overlooked as well. Right-sizing and upgrading motors allows us to bring about significant energy saving.
Pumps are another major load-heads of any facility, where energy consumption is determined by the head and the flow. ESIPL has conducted extensive studies on different pumps’ performance and has encountered improper selection, higher safety margins, improper water balancing, fixed flow, evolving use environment as reasons for higher energy consumption. Pumps are governed by affinity laws, which implies that any change in required flow can lead to reduction in power consumption by ∛.
Load Scheduling and Contract Demand optimization usually require behavioural upgradation and deep data analysis. ESIPL conducts load-time assessments & contract demand optimization of the facility so that clients do not incur redundant demand charges or higher energy charges for operating non-critical loads at peak hours.
Most of the state electricity boards are shifting towards kVAh billing, and even those who are not use the mechanism of penalizing clients for lower PF & incentivizing for PF close to unity. Higher PFs also result in substantial increase in the life and health of equipment. ESIPL has successfully commissioned several cases of PF upgradation across manufacturing and commercial buildings.
ESIPL constantly works with disruptive and alternative fuel suppliers to substitue Client dependence on fossil fuels used for boilers or HWGs. Green fuels are not only cheaper in cost, they are stable in pricing and environment friendly leading to reduced spend and a greener planet.
