[Bldg-sim] 8760 Load Profiles

Wed Jun 21 07:58:33 PDT 2017

Dear Coles,
Quoting Dru Crawley (who got it elsewhere) "All models are wrong, but some
are useful".  That applies doubly to instances where you want to match
metered data with modeled data.

As I participate in both the modeling and commissioning arenas, I'm keenly
aware of the (literally) hundreds of ways a building can operate
differently than imagined by the modeler (or DOE's reference models).
Differences are often major!

The scenario you describe appears to be what a statistician would describe
as "under-constrained" - you probably don't know enough details about
actual operation to understand which of several low RSME calibration
solutions are correct. :(

At the risk of blathering on too long, I think your project places you on
the leading edge of energy practice and research; good luck!

p.s., there are some nifty software tools which promise effective analysis
of buildings with BMS'. Among them are SkySpark
<https://skyfoundry.com/skyspark/>and a few others, with newcomer BuildPulse
<http://www.buildpulse.com/>. Their approach is to apply FDD rule sets and
identify operational problems.
Another nifty tool is the (totally) wire-free CT sensors from Panoramic
Power <http://www.panpwr.com/>, which we've used for sub-metering complex
facilities.

*Coffee conversation:*… the minute one is labeled mean-spirited simply
for raising an opposing view, debate is silenced. If we disqualify
legitimate discussion, we compromise our ability to know the truth. We
need to cultivate the ability to disagree civilly and not take
opposition personally. We must also have the grace to allow our own
views to be challenged with evidence and reasoning…
