Melissa,
Wow, when you mentioned hourly load profiles for commercial buildings, that really brought
back to me memories from that time long ago! For years, the work I did on load profiles
was funded by the Gas Research Institute in Chicago (now I think merged with GTI), exactly
for the purposes that you apparently used it for, i.e., as a convenient way for engineers
and manufacturers to evaluate their equipment without having to do building energy
modeling. For a while, there was a slow but steady stream of people who were interested
in the load profiles, each of whom wanted some level of customization - like a heat pump
guy who didn't want a night setback, etc. The realization struck me to make the building
prototypes as flexible as possible, since very few people wanted just to rerun the model
with no changes at all! So, I kept "macro-tizing" the building models so at the end, it
was just a collection of macros and include files that people can switch out. Then,
there was one consultant who came by my office to say he wanted to get the whole set of
hourly load profiles and asked if I could put it on the Web so he could download it (mind
you, this was in the 1980's). I told him I thought that would be incredibly slow, but his
response was, eh, we'll just let the machine sit there for a night. Amazing how much data
are now transferred over the Web every single moment.
