Comment #1Amendment: Proposed MINHERS Addendum 49f, Credits for HVAC Installation Quality Grading, Draft PDS-01Page Number: 158Paragraph / Figure / Table / Note: 310-2020 Appendix AComment Intent: ObjectionComment Type: TechnicalComment: Heating temperature for Roanoke Virginia is based on Greenbrier WV Airport - resulting in a design temperature of 11 degrees. Meanwhile - Montgomery County Virginia, which is at a higher elevation and typically is 4-10 degrees cooler in winter has a design temperature of 15 degrees. The Energy Star winter design temperture for Roanoke is 19 degrees. Is this an error or a change in measurement methodology? Proposed Change: Confirm winter design temperature for Roanoke Virginia

Comment #2Amendment: Proposed MINHERS Addendum 49f, Credits for HVAC Installation Quality Grading, Draft PDS-01Page Number: 8 and 10Paragraph / Figure / Table / Note: Eq. 4.2-10, 4.2-12, 4.2-22, 4.2-24Comment Intent: Not an ObjectionComment Type: TechnicalComment: In the four equations noted above, the term Qdev was inadvertently used, which is not defined. This term represents the Blower Fan airflow deviation and was intended to be named FAF, a term that is defined. Proposed Change: Replace "Qdev", a term that is not defined in the standard, with "FAF". Despite the discrepancy in name, the term was always intended to represent the Blower Fan airflow deviation.
