NOTE: EmPCalc v5.9.2 is a mandatory upgrade due to the new features and bug fixes that were completed. It is required for EmPower workscopes with a Heat Pump Demonstration Project.
New projects submitted after January 1, 2021, using earlier versions of EmPCalc will be returned requesting that the updated version be used. Approved in-progress projects may continue through project completion using the EmPCalc version at the time of approval.
EmPCalc v.5.9.2 can be used for both EmPower and HPwES projects.
Versioning: Updates will be made in groups of measures and contractors will be notified when we publish updates. The latest version is below:
- EmPCalc v.5.9.2→ rev. 01.04.2021
Version Updates:
5.9.2
General:
Fixed issues with savings calculations for delivered fuels affecting AHP projects exported to the Portal.
Insulation:
Fixed issues with Landlord Contribution Measure dropdown list.
ASHP/GSHP Calculator:
Fixed formulas for Coal pricing.
Base heating system Fuel Use Override is now locked with Annual Fuel Use that is entered in the Cover tab.
ASHP Calculator:
Fixed HSPF Total/Weighted Avg so it now averages HSPF when there are multiple systems with different HSPFactors.
Added ‘Outside’ text to Design Temp (this field should be outside Design Temp from Manual J, not inside.)
5.9.1
Fridge_Freezer:
Fixed issues preventing Freezer 1 from calculating savings.
ASHP/GSHP Calculator:
Fixed formulas for Coal pricing.
Approval:
HP Demo Electric and Ductwork modification costs are no longer double accounted for in the heat pump cost.
Modeling Limitations: Development of EmPCalc is ongoing, there are still some measures that cannot yet be modeled. We will continue to add capabilities (see list below) and roll them out as they are completed. For projects needing the capabilities listed an alternate modeling software will need to be used.
- Boiler pipe insulation
- Duct Insulation
- Duct Sealing
- Dehumidifier
- Windows
- Storm Windows
- Window Insulation
- Exterior Doors
- Storm Doors
- Dishwasher
- Clothes Washer
- Clothes Dryer*
- Multiple water heater replacements
- Multiple heating system replacements
- Any insulation surfaces that are not in the current insulation drop-down menus or any unique insulation scenarios cannot currently be modeled in HPXML Compliant EmPCalc. Alternative modeling software will need to be used.
*Note: The NY HP Portal does not support clothes dryer improvements. While the measure was left in EmPCalc, it should only be used on EmPower projects not HPwES or AHP or Market Rate projects. If the measure is mistakenly exported into a .XML file and uploaded to the HP Portal the user will receive the error below. To fix this error simply delete the dryer data on the Dryer Conversion tab.
- Measure ‘clothes-dryer-measure-1’ must have between 1 and 1 installed_system system(s) only, or a valid MeasureCode
Notes Tab: The Notes Section (tab) in this version of EmPCalc works differently than the non-HPXML compliant EmPCalc in that you cannot edit the notes. The Notes tab in our HPXML compliant EmPCalc is used as a catch-all for notes entered throughout EmPCalc. For example, if you were to propose a Health & Safety measure on the Health & Safety tab, under the measure description, that description would populate in the Notes tab. If there are notes that you would like our Reviewers to see please enter them directly in the NYHP Portal.
Feedback: We need your feedback to make this tool better. All constructive feedback should be sent to Earl Hicks (Earl.Hicks@clearesult.com) and cc Pete Hoke (Peter.Hoke@clearesult.com) with the following information:
