[Bldg-sim] Fuel cells and peak shaving

[Vikram Sami]

As far as I know, you can take credit for this for LEED EAc1. The credit
is based on energy cost and not BTUs, so assuming you have a TOU  rate
structure, you should show some savings there. There are potentially
some significant environmental benefits from peak shavings too - most
utilities have larger plants that run full time for a base load. They
then supply the additional loads with peaking plants - either natural
gas or diesel powered. Cutting demand reduces the need for peakers to
come online. 

 

 

 

 

Of course - Coal power is the ultimate in peak shaving ;-)

Subject: [Bldg-sim] Fuel cells and peak shaving

 

We've got a client that wants to look at ways to peak shave using
generators and/or fuel cells.  For LEED EAc1:  are those acceptable ways
to show energy savings?  If I set up a generator in eQuest (or using ECM
if I can't figure the generators out), can I have a base utility rate
for the baseline building?  Or do I have to have generators / fuel cells
in both models?

 

Thanks in advance,
