EOS makes changes to set-points in the BAS to ensure minimum energy cost while maintaining compliance.
Datacenters represent a large component of a Communications Service Provider’s (e.g. telecom, cable, internet, satellite, etc.) energy cost. A datacenters’ energy consumption is primarily comprised of the networking equipment required to provide the services for their customers, with the balance of the energy load comprised of the HVAC needed to cool the networking equipment, so it remains at an appropriate temperature and does not fail, thereby effecting customer service. This is paramount to the service provider.
A datacenter’s efficiency is measured in terms of PUE – power usage effectiveness – a measure of the ratio of power used to by the networking equipment to the power required to cool it. While the network load is mostly constant, there are optimization opportunities the overall cost of the energy consumed by the datacenter. Specifically, cost optimization is used to most efficiently reject the heat from the central chilling plant and condenser water system, to triage the HVAC services against the utility rate structure, and to optimize the data center aisle cooling.
EOS analyses all the data to determine what set-point changes to the equipment would ensure optimal current conditions in the building at minimum energy consumption. It also looks ahead and determines the most energy efficient way to manage the building from day-to-day, season-to-season, and space-to-space. Then as often as every five minutes EOS makes changes to set-points in the BAS to ensure minimum energy cost while maintaining compliance.
