Are we measuring the same thing? How HERS and Passive House provide different answers to different questions.

PHN Presents

The Home Energy Rating System (HERS) and Passive House compared side by side on a single-family home: where and why the two methods diverge, why strong Passive House levers can barely move a HERS score, and how Passive House teams can work with HERS.

Key points

• The main components of HERS ratings and of the Passive House standard.
• Where the priorities of HERS and Passive House evaluation diverge.
• How those different priorities change the resulting energy performance evaluations.
• How Passive House teams can work successfully alongside HERS.
