HVAC Technology Drives Sustainability By Reducing Energy Footprints

It is time to address the alarming situation of excessive energy consumption and deliberate the application of energy efficient measures to ensure a sustainable and livable life balance while leading a cost effective lifestyle.

In the last few decades, the energy consumption barometer of India has witnessed an alarming upward graph. And, in fact, according to "New Outlook for Energy: A View to 2030," report, this demand is expected to be 35% higher by 2030. It is therefore, clear that there is an urgent need to inculcate progressive methods to reduce the current energy consumption. In India, the launch of the Environmental Conservation Act in 2001 recognized the importance of rationalizing the energy usage and developed policies to ensure energy efficiency by introducing the Bureau of Energy Efficiency (BEE) in 2002 and the National Mission for Enhanced Energy Efficiency (NMEEE) in 2008. 

With rapid urbanization, it has been noticed that due to sustainable infrastructural development energy conservation is looked upon more critically. Installing such energy efficient systems- high performance controlled ventilation, efficient lighting systems, use of natural energy sources etc. In fact, a structure’s Heating, Ventilation and Air Conditioning (HVAC) system usually utilizes a major share of the total energy consumption, making it a vital focus area.

HVAC companies across the world have invested massive amounts of money in R&D to introduce and implement innovative energy efficient technologies. The Indian HVAC market, which is likely to reach $7 Billion by 2022, is expected to witness steady and strong demand in the future due to the robust infrastructural development planned and underway. Some of the few revolutionary technologies that have been introduced have allowed India to create its first Net Zero Building- Indira Gandhi Paryavaran Bhavan in New Delhi

HVAC companies have been majorly focussing on energy and associated costs required to run the equipment throughout its lifetime. Product Technologies in the system are centred around variable speed and in the system design approaches like radiant cooling systems and demand load segregation etc, have been taken into consideration. The introduction of star-rated room ACs have been further developed into smart AC’s that are voice (Alexa) controlled or Adjustable AC’s that increases or decreases its tonnage usage basis the number of people in the room or the ambient temperature. Other technologies like eco-friendly refrigerants, advanced air-purifiers, stabilizer free operations, and low frequency torque control and automatic operations during overload conditions have also been introduced in the residential air-conditioning domain to ensure maximum output with least energy

On the other hand, in HVAC projects, companies have been integrating technology with the use of IoT; from one location, IoT helps connect the HVAC system. Monitoring performance through IoT is not just for preventive maintenance but for predictive analysis as well. IoT also helps in close monitoring of energy costs, resulting in lowering of cost of ownership by comparing the actual performance with the base line standards for the defined application. 

The advancement incurred in developing efficient HVAC systems help in contributing towards the optimum utilization of energy as well as its conservation. Optimization of innovative and green HVAC systems have led to substantial savings of the end users. It is time to address the alarming situation of excessive energy consumption and deliberate the application of energy efficient measures to ensure a sustainable and livable life balance while leading a cost effective lifestyle.
