In May 2017, the HPDC released the most current version of the HPD Open Standard, version 2.1.
A new version of the HPD Builder will also be launched with the release of the new standard. You will be able to create or edit HPDs to the 2.0 Open Standard until the launch of the 2.1 Builder and the specific date will be announced as we get closer to the release. Once Builder 2.1 is released, Builder users will have the option to update HPD 2.0s to the 2.1 spec, using an automated tool included with Builder 2.1.
We encourage you to republish existing HPDs to take advantage of HPD 2.1 improvements and take that opportunity to also run a completeness check and a pre-Check for LEED v4 compliance!
