How Energy Management Systems Work – Part 1

In our experience, many legacy thermostats at individual buildings are inaccurate or defective in operation.  Even when programmable thermostats are used, they may not be set correctly to account for changing needs throughout the day or external weather conditions, or they may not be programmed at all.

With today’s energy management systems, operators can upgrade an inconsistent and unreliable base of thermostat controls with precise, networked thermostats whose set points can be easily programmed from a central location for each building. These thermostat controls are also linked to an array of indoor and outdoor sensors that, combined with intelligent data collection and profiling, help determine each location’s most efficient and economical temperature settings.

The energy management system collects and communicates real-time temperature and HVAC system performance data, measured against each location’s outside temperature, local weather conditions, humidity, and cloud cover conditions. All of this data is collected and logged on a real-time basis, creating an ongoing profile of each location’s indoor and outside environmental conditions, energy use and continuous HVAC system performance. This data, combined with the analysis and reporting features of the system, gives unprecedented insight into each building’s energy usage, areas of inefficiency, and corrective courses of action.

Most importantly, an energy use profile, created for each building, helps you easily create an optimized setpoint program to maximize energy savings at each location.
