A large office building enlists Datapult Energy Information Services to evaluate their energy use...
Two boilers in the basement are set up to run in alternating 15-minute intervals to avoid an excessive peak load... or are they?
According to Datapult, the two boilers are not staggering their time... they are going on and off at the same time, causing excessive load peaks... precisely the opposite of that was intended!
By correcting this timing problem with the boilers, the building stands to save considerably in electric charges...
Saving $8,500 per month,
5% savings annually.
