How well do these operate if the electricity fails? If it’s airtight wouldn’t you eventually run out of oxygen?

You can open the door or window.

As a side note, Fine Homebuilding and its associated property Green Building Advisor (https://www.greenbuildingadvisor.com) are exceptional sources of information on quality residential construction. HGTV and similarly oriented renovation programming dominate this media, but there is a large community of people trying to do things correctly and making use of the appropriate technology to do so.

How much does this construction cost vs. standard building? Looks like it could be relatively cost competitive.

I understand that the construction materials were chosen to be healthier, but wouldn’t it be even better to have a ‘loose’ house with those same materials?

It probably would make sense to have controlled and well-managed ventilation in airtight houses. It'd still be more energy efficient to heat and cool at a particular ventilation point rather than have what traditional houses have... a lot of leakage everywhere.

FTA:

> It was to determine how well the HRVs

How many of those homes tested installed a proper mechanical ventilation system?

Anyone that is serious about air tightness will tell you that you need to manage the air transfer with an HRV or an ERV so it's filtered, controlled, and avoids these problems.

I found the study you are quoting:

https://pureadmin.qub.ac.uk/ws/portalfiles/portal/31281945/C...

Results from the occupant interviews suggest inadequate knowledge of the ventilation system, with all Code 4 homes stating ‘not sure’ when asked about various features of the MVHR system, including the current settings, changing of filters, boost mode function and location of controls.

Knowledge of the MVHR system was considerably lacking in Code 4 homes. All households stated that they did not know where the controls for the system were located, or how to change the settings.

They asked people who moved into "airtight" social housing if they understood how the systems worked to keep the air moving and people said no.

No wonder they had worse air quality...
