[Bldg-sim] Modelling for retrofit ECM's

[Carol Gardner]

Hi Rohini,

When you are bill matching there are not magical ways of doing things. You
pretty much have to put what's in the building in your model. Those things
you can control. The tricky part is to figure out how the building is really
being operated and to get the most accurate weather data you can for your
site.

Cheers,

Carol
