There are other low energy standards such as EnerPhit and PHI Low Energy Building (LEB):

These are not Passive House standard, but are still a high standard of energy efficiency. Last year, following a pilot, Cambridge City Council opted for their own "Cam Standard" for council-owned properties that is slightly lower than Passive House but higher than LEB. They found that fulfilling some Passive House requirements was disproportionately costly for the benefit.
That Passipedia site - https://passipedia.org/ - is probably the best jumping off point for people who really want to dig into Passive Houses.
