[Equest-users] Electrical loads

[Brahme, Rohini UTRC]

There is a requirement of 25% of the total cost should be misc loads for
LEED. 

Also, when you look at the breakdown of energy efficient residences, the
plug loads is a big chunk.

Subject: Electrical loads

 

When modeling energy use in a residential high-rise I set up schedules
for misc. loads like refrigerator, microwave, oven washer/dryer etc.. I
actually lumped these all into 1 schedule, approximated their actual
loads and then applied a daily and weekend schedule to approximate their
use.

 

My schedules showed pretty low percentages since these appliances would
not be used much.

 

I received comments from the client and another modeler that these loads
are inconsequential and should not be incorporated into the model.

Here is the comment

Plug-ins are typically assumed to be the copiers, medical equipment, etc
and I would think refrigerators, microwaves because how do we really
measure the use of such things in a current comprehensive computer
modeling situation - it's beyond a scope of comparison in a finite way
- that's why MISC should be junked.

 

 

Any opinions?
