3. By direct formula, as stated in the measure description in this section. This applies to the following measure:

   • E01: 11.5.2.1, “Improved Envelope Performance” 11.5.2.1 E01: Improved Envelope Performance. To achieve this credit, building envelope measures shall be installed to improve the energy performance of the project. Measure energy credits for improvement of the building envelope energy performance shall be determined based on the following:

EC E01 _ calc = 1000  EPF---------------------------------------------------- E01_base EPF E01_base - EPF prop -

where EC E01_calc = energy credits achieved for improved envelope performance EPF E01_base = base envelope performance factor calculated in accordance with Normative Appendix C EPF prop = proposed envelope performance factor calculated in accordance with Normative Appendix C 11.5.2.2 Improved HVAC Performance. To achieve these credits, equipment shall provide HVAC performance improvement in accordance with Section 11.5.2.2.2, 11.5.2.2.3, 11.5.2.2.4, 11.5.2.2.5, or 11.5.2.2.6. Equipment shall also meet applicable requirements of Sections 6.4 and 6.5. Credits shall be as shown in Section 11.5.3 or as specified in each subsection for building use types where base credits are included in Section 11.5.3 tables. Use of multiple credits from this section shall be allowed. 11.5.2.2.1 H01: HVAC System Performance Improvement (Reserved) 11.5.2.2.2 H02: HVAC Heating Performance Improvement. To achieve this credit, space heating equipment shall exceed the minimum heating efficiency requirements by 5% or more than listed in the tables in Section 6.8.1. The measure energy credit for heating efficiency improvement (EC HE ) shall be determined as follows:

= EC H02 _ base  ------------0.05 -

EC H02 _ adj = EC H02 _ base
