SHW in the CBECC user guide #772

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This isn’t an IES issue as such but something I would like to clarify. I 
would have thought that SHW would typically mean service hot water but your 
user guide states it refers to solar hot water. I can’t find anywhere to 
input typical solar hot water parameters in the CBECC program so is it a 
mistake? A customer was asking as he says the baseline has a requirementfor 20% 
to be sourced from solar.

You are correct regarding the user’s manual, this should say service hot 
water.  We will correct this in the v3 manual.  

The current version of CBECC-Com, and this will remain the case for v3, has no 
inputs for solar systems.  It has recently been pointed out to us that the 
standards contain a prescriptive requirement for multifamily residential 
buildings to include a solar system which provides a 0.20 solar fraction.  We 
are currently discussing how to address this requirement.

Solar thermal data has been incorporated in v3a and later, with extensive 
additions for reporting in v3b.
