Addendum r establishes the hierarchy of the decision-making process for selecting baseline HVAC systems.
Addendum k directs the modeler to use the default assemblies in Appendix A for baseline opaque envelope assemblies.Other addenda included in the excerpt are: Because unregulated loads are not included in the compliance target in Table 4.2.1.1, beyond-code programs that encourage improvement in unregulated loads may wish to modify the target to include those loads. Therefore, a beyond-code program may wish to set a target less than is shown in the table (a target of 0 is a net zero building), while compliance with a previous version of the standard may wish to set a target above what is shown. The intent is that any building energy code or beyond-code program can use this methodology and simply set the appropriate target for their needs analogous to those in the table. By this, a building of any era can be rated using the same method with the same baseline of compliance. The second change is that the baseline design is now fixed at a certain level of performance, the stringency of which is expected not to change with subsequent versions of the standard.
