[Bldg-sim] Building envelope

[mark dewsbury]

For software calibration we start with the simplest envelope of all first.
We can then establish which algorithms require tweaking. We can then change
bits and see what happens. 

We have identified many aspects of the HER software requiring further
investigation.

We are now in the last stages of some intensive subfloor research. 

About to look at reflective versus bulk subfloor insulation, followed by
thermal mass. 

We can mimic internal heat loads and HVAC operation. 

Windows one day in the future when the other envelope elements are tested.

These are great,  I wonder if when simplfying energy modeling you loose the
value of some software tools? Without such things as windows, lighting,
HVAC, etc some software may seem like it is a better tool, but then modeling
real world buildings another software tool may work better.. Just a
thought...

Now THAT would be a better test than I envisioned, Jon.  I was just thinking
of comparing models, NOT comparing them to a real building.  Sounds like fun
though!

Mr Wichert:  And the next question would be , "Where do we find such an
existing  bldg. with real demand and energy data set already available?."
I would assume that many such exist, but I , for one, would not know how to
begin to identify one.  Maybe the folks at NREL or LNBL have access to such
data, and maybe one from there could kindly respond to your request?

Yes, of course.  I was thinking of a non-residential one-story wood frame,
steel studs, or concrete block building with one or two windows per side and
a cathedral ceiling on a poured slab.  A basement would be OK too, but not
really necessary.  Either no zoning at all or a core for toilets/break rooms
and open plan office all around.

I mean REALLY simple.

Mr Wichert: Although I like your idea of head-to-head modeling, I think it
would only be real useful if one could start with a "simple" bldg. for
wahich there was existing good quality energy and demand data set.   That
way, one could not only have "precision " but also some baseline of
"accuracy".

 

I like you idea,  but to start small and simple would be key for me,  so as
not to commit a large amount of time.

 

Thanks for your suggestion.
