Kilawatt instrumented the area, gathered data for three weeks, and determined that the real issue was that all of the thermostats were being influenced by the sun, shutting them off. Further there was no return air system for the heat pump system.
The Fix: $4,000
Avoided Cost: $40,000

A manufacturing facility had Kilawatt Technologies review their energy usage and determine if there was any energy savings to be had. They were about to embark on an approximately $80,000 HVAC upgrade to address some comfort issues within their facility: the office area was way too cold with everyone having an electrical space heater under their desk.
Kilawatt initiated trending for three weeks and also reviewed and analyzed some long term legacy trending that likely had been initiated by a previous owner of the facility for reasons unknown.
The building’s mechanical equipment is working perfectly. The internal temperatures are rock solid. The building’s equipment is doing exactly what it is being told to do, and doing it very well.
The problem is that the system seems to be set up completely backwards. The heat is only on during unoccupied hours. In fact, the boilers appear to be locked out during occupied hours so requesting additional heat via the Thermostat on the wall is ignored by the system.
Oh, and the HVAC system upgrade, was using outdated technology that would not have addressed the challenges the building was having and would have been connected to the same control system that caused the problems in the first place.
