Pull Request Description

This is at OS-HPXML SHA: d741ae7421b8bfc5284b6869eed175804f029f77.

Testing

This feature was tested using a base branch at 87bfe1aeb9d117fbad6f33793a5497d6f7dd7d71 and this feature branch at d741ae7421b8bfc5284b6869eed175804f029f77.

Upgrades: ResStock was run with these upgrades for both the base and feature branch.

• ducted "ASHP, SEER 20, 11 HSPF, CCHP, Max Load" for homes with ducts
• ductless "MSHP, SEER 20, 11 HSPF, CCHP, Max Load" for homes without ducts

Impacts: The results showed that there was impacts to heating, cooling, heating fans and pumps, cooling fans and pumps, backup heating, backup fans and pump end-uses.

Here is a table summarizing the average impact across the datapoints simulated.

Here are some plots showing the impacts to these particular upgrades.

In general, the results are going to be very sensitive to the specific SEER & HSPF levels that were chosen different performance levels may have a slightly different impact due to the change of the performance curves to better reflect the NEEP database.
