ENERGY MANAGEMENT OPTIMIAZATION DESIGNS
We have energy systems that are unique to NMSU.
Chilled water pump by-pass system was custom-designed by our Energy Management Systems Manager. It is a chilled water pump “by-pass piping design” that allows for free-flow operation when our Central Utility Plant pressures are sufficient to flow the building without the need to operate booster pumps, saving electrical consumption.
We have a Master Global Occupancy Schedule that is in use to have a staged shut-down of the campus mechanical systems to allow for stabilization during the transition to unoccupied periods. The same staging is in effect for system start-up which gives us the ability to limit peak demand draw on electrical and chiller systems reducing the impact of excessive energy demand.
In addition to the above, we have moved to a “load demand-based” temperature set-back control strategy instead of outside air temperature reset control strategy. Air is run to individual rooms according to the feedback from our occupancy monitors. We are using this system on approximately 5% of the buildings on campus and designing more each day.
