How IoT-based Smart HVAC System Can Help Commercial Buildings Achieve Energy Efficiency

By Michael Rosario, Construction Tech Review | Tuesday, December 15, 2020

The commercial buildings can use IoT for their smart HVAC to achieve energy efficiency as they offer various efficiencies.

FREMONT, CA: Sustainability and efficacy are at the top of the public agenda these days. Vendors, retailers, consumers, and the general public are looking through the lens of environmental change at goods and services. Companies aim to meet growing expectations for creativity in producing goods and customer support while carefully balancing capital and aiming for the lowest impact on the environment.

It has never been more difficult or more necessary to manage an environmentally and economically sustainable company through the entire supply chain.

HVAC as highest energy consumer in buildings

Today, energy consumption has become an important issue. In the building sector, heating, ventilation, air conditioning, refrigeration, or HVAC systems are responsible for up to 60 percent of a commercial building's energy usage. There are HVAC faults in all large commercial buildings, and most of the expended energy is lost due to malfunctions in either the equipment itself or the logic control systems.

The faults in the system might get discovered due to the high energy bills. As field service engineers struggle to determine the correct cause of energy consumption, the cost can increase because of the spike in energy consumption and then for services and fixing the equipment.

Three use cases leading to enhanced energy efficiency and customer satisfaction

Such issues can be solved by using IoT technologies to collect data from HVAC and building sensor data, and analyze it to look for wasteful trends, contextualize it with other data sources' appropriate information, and act when and where it matters.

In addition to the immediate advantages that they offer in better customer service and product field support, the customers have described three use cases as contributing to overall improved energy efficiency in buildings:

Real-time condition monitoring – Real-time monitoring of HVAC's condition to dispatch intervention technicians only when required, rather than periodically. Monitoring of conditions can increase uptime and decrease maintenance costs.

Remote diagnosis – Performing root cause analysis before dispatching field engineers for an HVAC malfunction recorded by the customer using data from the affected HVAC. Remote diagnosis will decrease site visits and boost the rate of first-time repairs.

Preventive maintenance – To avoid problems from occurring, review historical HVAC data to predict possible failures and estimate when maintenance must be performed. Preventive maintenance will boost the longevity of the product and save on repair costs.
