Some need to be slain at birth; while others have "legs".
Balance point temperature...
Should we send it to the naughty step - or run it up a flagpole so we can salute it ?
Energy Managers must make decisions somehow - they must be the judge.
Our job is simply cajole, provoke or tease thoughts out stubborn unthinking material (do you have any I can use ? )
Objectivity's a fine thing, "you can't manage what you can't measure"- YAWN !
OK but what if you MUST manage what you can't measure.
A small amount of knowledge leads
up s#%t creek without a paddle to mistakes.
So which is it when we consider Balance Point Temperature ?
The case for the prosecution:
If it please m'Lord... We heat buildings to stay warm. Sometimes it is warm so we don't need to heat. Somewhere between these two a decision is made. That point is the balance point temperature. Getting this right is the first pillar of energy management.
Objection... If it was as easy as that we'd all be doing it. My learned friend refers to a mythical unicorn. Saving energy is essential and much is waste but ...
Yes we have motive, and certainly each day we have the opportunity - it's only a switch on the wall (or in the basement) - But we lack one critical aspect - the means.
The means to judge, as we must have if we are to be found guilty of waste.
Where I ask you, or at what temperature (Celsius for my colonial listeners) - do we need to switch boilers on, and conversely when do we switch off? About 10 ? - So why are there red days at 25C (77F to save the hassle) ? Do we need to heat at 1C : 33.8F ?
If so what about the weekends , school holidays - Should we turn heating off at night or when we stop ventilating ?, Part or all of the building ? - we must judge for ourselves.
I call the first expert witnesses : kWIQly - They can sort this out !
"I rest my case !" , the cry goes up - "mistrial !"
