Benchmarking the billing data.

Hello All,
I am modelling an 124,000sqft five storied building in eQUEST
3.61. I am benchmarking the model's electricity, demand and gas use using
the actual billing usage. I am able to benchmark the electricity and demand
use but not the gas usage. I am able to get pretty good streamlining in
summer but not in winter. In winter the total therms is up by 154% of the
normal billing usage.

Does eQUEST overestimates the gas usage.

Any clue, help or direction would be appreciated.

Thanks in advance,
Kazim Mirza

What type of HVAC system do you have? If it is a VAV, it sounds like
your system is functioning fine (summer is when VAV matching wreaks

Check your winter outside air, window type, operating hours (do you heat
at night ??).
