Remote Monitoring: A New Era of HVAC Management
First, There Was the Fan...
Then came the summer of 1902.The humidity was unbearable. It was so bad that the pages of an NYC print house started to swell and the printed ink blurred.
They turned to the Buffalo Forge Company for help, which tasked Willis Carrier, a 25-year-old engineer, with designing a system to reduce humidity and lower room temperatures.
The cooling system was a success, and Carrier continued developing his invention. In 1922, he created the safer, smaller, and more powerful Centrifugal Refrigeration Compressor.
The beginnings of the HVAC industry can be traced back to this moment.
Fast forward to today, and HVAC systems have evolved far beyond those early iterations, becoming infinitely more complex: both mechanically as well as in their communication and control capabilities.
Facility Managers and the 4th Industrial Revolution
In the early 2010s, the Fourth Industrial Revolution began to reshape the HVAC industry. At its core was the Internet of Things, a new digital connectivity paradigm and technology that enables machines to communicate with one another and be remotely controlled via the cloud.How did this impact the daily lives of facility managers? In one word: Positively.
The Benefit: Commercial HVAC Monitoring
Before IoT, facility managers overseeing HVAC systems across multiple floors, buildings, or sites faced a unique challenge: they or their staff had to visit each unit in person to monitor, service, and manage them.In worst-case scenarios, when problems manifested simultaneously across multiple sites, maintenance staff were forced to rush between locations, wasting valuable time on minor issues with simple fixes. The outcome was lower productivity and delayed response to more critical malfunctions.
Thankfully, this operational reality has changed.
With systems now digitally connected, facility managers can monitor HVAC equipment across commercial buildings, retail spaces, hotels, Airbnb properties, and other sites using a single remote interface from the comfort of their office: identifying issues and passing targeted information to the appropriate service provider to ensure that the right technicians are dispatched with the right tools and parts.
And the good news doesn't stop there.
VRF Power Distribution
Once HVAC systems became connected and trackable at scale, operational visibility was no longer an insurmountable limitation. However, energy efficiency remained a major challenge.This challenge is particularly relevant for VRF systems, which are widely deployed in large commercial and multi-tenant buildings due to their efficiency and flexibility. In many VRF installations, a single outdoor unit serves multiple indoor units, often across zones occupied by different tenants. While efficient, this architecture makes it difficult to accurately attribute energy consumption at the indoor unit level, complicating fair tenant billing and optimization efforts.
Happily, the same IoT-driven connectivity also enables deeper visibility into HVAC energy use, with smart VRF power distribution solutions providing unprecedented consumption transparency. By measuring VRF outdoor unit power usage and allocating it accurately across connected indoor units, facility managers gain a clear, unit-level view of energy use.
This granular visibility not only enables fair and accurate tenant billing but also makes it possible to pinpoint the sources of energy inefficiencies, whether tied to specific zones, equipment, usage patterns, or operational issues.
