Rooftop HVAC units are almost always one of the biggest energy consuming devices for any commercial and industrial (C&I) buildings. In fact, C&I buildings consume more than a third of the energy used in first-world countries, and HVAC units account for almost half of this energy. They are also one of the largest contributors to greenhouse gas emissions.
The fact is that rooftop units – or RTUs – hold enormous potential for dramatic reductions in both energy costs and carbon emissions. This potential has gone largely unrealized, however, because RTUs have long been one of the least intelligent of a building’s energy-consuming devices. Yes, there are smart thermostats and building management systems that definitely help, but only to a point because even with these energy efficiency tools in place, RTUs function in isolation, cycling on and off with no knowledge of how and when other units are operating. As a result, RTUs have remained largely untapped as an opportunity for smarter energy management and the accompanying energy savings.
