Designed to Passive House principles is not the same as Passive House.
Principles are sound in theory, but without measurement we do not actually know their impact.
A lot of people, including architects and architectural designers, will say their project was designed using Passive House principles. Here is the issue: it sounds great in theory, but it is often not effective in practical application.
Passive House principles are sound. But if we are not measuring them and we are not assessing them before the building is constructed, then we do not actually know their impact. What ends up happening is people are sold a theoretical solution without the practical grounding underneath it.
When those principles and practices are properly integrated into the design process, evaluated with PHPP, and held to account, that is when we see tangible results. That is when architecture delivers healthy, comfortable, high performance homes with genuinely low power bills.
The difference between intention and outcome always comes down to measurement. Principles set the direction, but tools like PHPP are what prove the design is doing what it claims to do.
