FOREWORD

Addendum e adds a new informative annex that provides guidance to authorities wishing to generate performance targets based on local or emissions data. Normative Annex C, "Forms," of Standard 100-2018 provides the following instructions for completing Form B as stated in Note (g): "Fill in the activity energy target (EUI_t1)_i from Table 7-2 (or table from AHJ) for each activity that has an area entered from Step 6."

The current default target tables in Standard 100 (Tables 7-2 and A-1) were developed based on CBECS and RECS and have been shown to have some significant differences from targets derived for a particular building stock using localized energy benchmarking data or other sources. As an alternative to a lengthy research process to refine the existing target tables, this informative annex contains instructions for AHJs on how to derive energy targets from regionally specific data sets that may be more applicable to their building stock. Additionally, in light of increased interest in quantifying and understanding greenhouse gas (GHG) emissions related to building energy use, the annex provides a process for converting energy-based targets into GHG-based targets.
