 Note that not all prescriptive requirements are included in the database as building energy codes and standards include many exceptions to certain requirements which makes the creation of practical data table difficult. Users of the database are encouraged to leverage knowledge of the codes along with the data tables.
 
-The database covers data related to ASHRAE Standard 90.1-2004 through 2022, ASHRAE Standard 62.1-1999 through 2022, and the International Energy Conservation Code (IECC) 2006 through 2021. It also includes specific data tables for the Performance Rating Method of ASHRAE Standard 90.1 (Appendix G). The structure of the database is documented [here](https://github.com/pnnl/building-energy-standards-data/blob/develop/docs/Structure.md).
