For a LEED energy model following ASHRAE 90.1-2010 Appendix G, we're modeling a domestic solar hot water system with:
3 flat plate collectors Solar storage tank Showers as primary end-use
Proposed Case: Modelled the actual solar thermal system
Baseline Case:
Does ASHRAE 90.1-2010 require the baseline to: a) Include an identical solar thermal system? b) Use a conventional system (electric/gas water heater) instead? c) Follow some prescriptive solar requirements?
Reference to specific sections in ASHRAE 90.1-2010 would be greatly appreciated.
