   * [10-14](section10/10-14.md): Baseline shall be modeled with the heating HVAC system efficiency per Tables G3.5.1-G3.5.6 (applies only to the heating efficiency of baseline furnaces and heat pumps).  Where multiple HVAC zones or residential spaces are combined into a single thermal block the heating efficiencies (for baseline HVAC System Types 3 and 4) shall be based on the  equipment capacity of the thermal block divided by the number of HVAC zones or residential spaces.

+  * [11-12](section11/Rule11-12.md): For large, 24-hour-per-day facilities that meet the prescriptive criteria for use of condenser heat recovery systems described in Section 6.5.6.2, a system meeting the requirements of that section shall be included in the baseline building design regardless of the exceptions to Section 6.5.6.2.
   * [11-13](section11/Rule11-13.md): Service water-heating energy consumption shall be calculated explicitly based upon the volume of service water heating required and the entering makeup water and the leaving service water-heating temperatures. Entering water temperatures shall be estimated based upon the location. Leaving temperatures shall be based upon the end-use requirements.
