A school district had an
underground LP gas storage tank to provide fuel for the High School emergency
generator. It was the responsibility of the building mechanic to order fuel
annually. A recent retirement put a new person in that position. Unaware of
this duty, the fuel level became low. This caused a gas smell on the area of
the generator.
When reprimanded for the failure to
order fuel the new person was told that this was a significant item and cost
the district $3200 each year. It was a line item in the budget and had been for
many years. Brought to light at the meeting, the cost appeared quite high. The
generator automatically exercised for 1 hour every Friday. The local utility
was very reliable and outages were infrequent. Given that the base operation
was 52 hours per year and outages did not exceed another 4 hours annually, it
was questioned how the generator could consume nearly $60 worth of fuel per
hour. An investigation found the tank leaked underground. The leakage accounted
for about $2600 of the annual budget.
Many times a budget figure is used
as a basis for performance. If “X” number of dollars has been spent, we are in
line with the budget and things are OK. We meet the budget and do not really
know what we spent the money on. It is important to know the value, to
micro-manage, every dollar spent.
Utilities and maintenance are ideal
places to capture inefficiencies through micro-management. As with the
generator fuel mentioned earlier, the ability to step back and analyze
individual pieces of equipment or complete systems can bring dramatic cost
reduction. Most managers can do this
effectively if their plate is not full already.

ReplyDeleteI could not agree more.
We at kWIQly believe energy management starts on the basis that nothing is necessary until shown otherwise.
Why do office chillers run over Saturday nights, Why does boiler boost happen if you are in Summer
etc etc.
Energy management is a state that occurs when you know what you are spending (energy) and you document the physical processes that explain why.
- e.g. so much air lifted in enthalpy by X requires n KWH per year.
Bottom line if you cannot predict use because you have no model hypothesis - it must be assumed wasteful.
Waste - guilty until proven innocent!
