Hi Greg, I found the below comment on chatgpt. My point is we have a 100% solar hot water system without any backup systems like electric water heaters. Do we only realize the complete savings by modelling the solar hot water system on proposed model and not modelling anything on baseline model? Appreciate your response!!
*"The baseline building shall use the same service water heating system type (e.g., electric resistance, gas-fired storage, etc.) as the proposed design, except that renewable energy systems (e.g., solar thermal) shall not be included in the baseline building design. *Interpretation for Your Case Proposed Case: You correctly modeled the actual solar thermal system. Baseline Case: You should not include the solar thermal system. Instead, model a conventional system (e.g., electric or gas water heater) that meets the minimum efficiency requirements specified."**
