ERG is a qualified partner for both Ameren Missouri’s and Ameren Illinois’ Retro-commissioning programs. Incentives from Ameren often reduce costs for a retro-commissioning project to less than one-year paybacks. In some cases, the payback periods for the RCx study and implementation can be as short as a couple of months.
An RCx Study will typically take 6 months, and implementation of the study often takes an additional 6 months. It is so cost-effective, ERG can usually finance it so there doesn’t need to be any capital outlay. If there is any equipment that needs to be replaced, ERG can often wrap the financing of the RCx into a lease instrument so that it’s off-balance-sheet and cash-flow positive from the get-go.
ERG specializes in providing comprehensive Retro-Commissioning (RCx) and Monitoring-Based Commissioning (MBCx) services tailored for existing buildings equipped with automated HVAC control systems, commonly known as Building Automation Systems (BAS). As a certified Commissioning Authority (CxA), ERG also offers Commissioning (Cx) services for new construction projects.
RCx studies are conducted on existing buildings exceeding 50,000 square feet and yield recommendations with paybacks of less than 18 months. With the inclusion of study costs, RCx typically demonstrates a return on investment (ROI) exceeding 50%.
ASHRAE recommends retro-commissioning either periodically or as an ongoing process (monitoring-based commissioning) due to the potential degradation of energy performance in building spaces and controls over time. Studies indicate that retro-commissioning can save between 8-40% or more of a building’s energy usage, with ERG consistently achieving savings of over 20%.
ERG stands as a qualified partner for both Ameren Missouri’s and Ameren Illinois’ Retro-Commissioning programs. Incentives from Ameren often result in reduced costs for retro-commissioning projects, with payback periods sometimes as short as a few months, including the RCx study and implementation.
An RCx Study typically spans 6 months, and the implementation phase often takes an additional 6 months. ERG’s financing partners can eliminate the need for any initial capital outlay. With such fast returns, waiting for a new capital expenditure cycle doesn’t make much sense. If any equipment is nearing the end of it’s life-cycle, ERG can often incorporate the financing of the RCx into a lease instrument on the replacement equipment, providing the added benefit of making a cash-flow-positive investment off-balance-sheet.
