v6.2 to v7.0¶

This release is coordinated with OpenStudio-HEScore v2.0.

What’s New¶

Envelope¶

• EPS wall type will now be selected if there is any continuous insulation on the wall, not just if it has the InsulationMaterial/Rigid subelement. See Wood Frame Walls.
• Assembly R-values can be used in for floors, attics, roofs, and walls.
• More R-values are now available in the HEScore construction codes for floors, attics, roofs, and walls. No action is required. Existing HPXML elements will be translated accordingly.
• A blower door test no longer requires the AirInfiltrationMeasurement/TypeOfInfiltrationMeasurement element. If a CFM50 or ACH50 value is reported, it will be used. See Blower Door Test.
• Added support for knee walls. See Knee Walls.
• Either an AirInfiltrationMeasurement or AirSealingMeasurement element is now required.
• Ducts in the garage will now be translated to unvented crawlspace in HEScore. See Duct Location Mapping.

HVAC¶

• Insulated ducts can now be specified by either the DuctInsulationThickness or the DuctInsulationMaterial elements. See Duct Insulation.
• Additional duct locations are now available. See Duct Location Mapping.
• Duct blaster measurements can be used to describe duct leakage. See Duct Leakage Measurements.

Water Heating¶

• The maximum allowed EF for a tank type water heater is now 0.95, and the maximum allowed EF for a tankless water heater is 0.99. Electric heat pump water heaters will continue to allow EFs between 1.0 and 4.0 inclusive.

PV¶

• PV Tilt is translated and used in HEScore. See Panel Tilt.
• Number of Panels is now being translated from HPXML v3 files. See Number of Panels.
