BASBuilding automation system. AKA BMS, Control system, Johnson, Honeywell, ATC, Struxtureware, etc.
It’s the parent for building systems. Security, HVAC, metering, etc.Controls the equipmentLight trending ability, troubleshootingScheduling

Easy to do in house
Good support
BenefitsThere are many benefits, here are a few
Know how the system is runningBaseline, make changes and compare
Quantify savings from changesIdentify bad buildingsBill by building for utilities accuratelySupport staff with proactive troubleshootingMany more….
RulesAbnormal sensors
DA, Space, vs. set point, other temps
Heating and cooling at same time
Equipment not matching commandAdd costs
Sequence appropriateIDEC, Cooling stages
Equipment sizingOperating 100% for period of time
Short cyclingAC equip, Fans, etc
Jordan CampusWe know there is a problem, but cannot quantify!
Using SkySpark for operation past and present
Have building level metering for verification as well as main meter
Easier way to prove savings
Valve Open?
