Facilities utilizing both a computerized maintenance management system (CMMS) as an asset management and maintenance management tool, and an energy management control system (EMCS) for obtaining real-time building performance data may benefit from utilizing some ECMS information for scheduling maintenance activities, instead of using traditional time-based maintenance scheduling.

Baseline Description: Separate systems
This is basically an enabling technology. It may make it easier or less expensive to implement, but would not likely save any more energy than an EMS that is not integrated into the CMMS.
"Typical" Savings: 5% Energy Savings Reliability: 2 - Concept validated
Setting up a computerized energy management system by itself does not save energy, but setting up such a system suggests a new awareness of energy use, and energy usage awareness alone should produce some savings. A new commitment to energy savings will produce much more aggressive results. An automated system built into the exisiting building automation system will be much easier to keep up with and is therefore more likely to produce more sustained results than a manual system. It is fair to attribute some savings to this feature of the program, so we chose the fairly conservative number of 5%.
Simple payback, new construction (years): N/A
Simple payback, retrofit (years): N/A
Cost Effectiveness is calculated using baseline energy use, best estimate of typical energy savings, and first cost. It does not account for factors such as impacts on O&M costs (which could be significant if product life is greatly extended) or savings of non-electric fuels such as natural gas. Actual overall cost effectiveness could be significantly different based on these other factors.

Technical Advisory Group: 2011 Energy Management TAG (#4) TAG Ranking: 24 out of 59 Average TAG Rating: 2.3 out of 5 TAG Ranking Date: 09/29/2011 TAG Rating Commentary: Not a technology per se. Isn't this already being done by industry? I have NOT encountered a facility that makes good use of their MMS. If combining EMCS and CMMS catalyzes comprehensive use of both then this would be a good thing!
