The Benefits of Implementing a Cloud-based Energy Management System


Efficient energy management is essential for large multi-unit operators to cut costs and manage HVAC assets nationwide. Thankfully, technology has advanced, opening the door for cloud-based energy management solutions to enter the field.


Recently, a large multi-location retailer partnered with BAYweb to pilot their cloud-based EMS across 83 stores. After the initial pilot test, additional store locations were incorporated into a subsequent staged rollout, including on-site installation of BAYweb programmable thermostats, HVAC sensors and control modules. Over a period of 13 months, every store in the company’s retail network was integrated into the BAYweb system.


Outcome and Benefits from System Implementation:


After several months of operation, the retailer’s facilities management team experienced a number of significant benefits from their implementation of the BAYweb intelligent energy management system:


  • Substantial energy savings: The ability to carefully monitor each store's energy use through BAYweb Cloud EMS and being able to develop thermostat temperature set points optimized for each store location, resulted in a significant reduction in kilowatt-hour use in each location, along with substantial per-store savings in natural gas heating costs.


  • Significantly lower HVAC repair and maintenance costs: By continuously monitoring the performance of every HVAC unit in every store in its network, the company significantly reduced its annual HVAC maintenance expenses, saving thousands of dollars every month. Further, by capturing detail on all HVAC systems in the entire store network, BAYweb Cloud EMS enabled the retailer to treat its HVAC system as a "portfolio" of individual units, each with its own comprehensive record of operating performance.


This insight enabled the company to establish predictive models of average HVAC unit performance, which further enabled the company to be far more proactive in financial decisions regarding HVAC maintenance. For example, with operating performance data on all of the HVAC units across its network, the company was able to make more financially sound repair vs. replacement decisions based on each unit's five-year capitalized cost.

Additionally, real-time monitoring of HVAC units has given the company a much better foundation to verify the diagnosis of repair technicians assigned to maintain each of its units, as they now have the data to compare each unit's performance with the technician's on-site assessment, to confirm the service actually required for that unit.
