Hey, I am working on a office project which will have no mechanical ventilation, and where it was decided to persue the flush out path for "IEQc4 Indoor Air quality Assessment".
Now I am wondering on how to realize the Flush Out without air handlers, normally being installed in mechanical ventilation.
Does anyone have experience with the Flush-Out procedure in buildings having just natural ventilation? Does anyone have some examples of air handlers, which could be used and the setpoints where they can be installed?
Looking forward to your help, thanks!

Hi Ivan! Were you able to get some guidance on this? I have the same question.

Building without mechanical ventilation can present a number of challenges related to indoor air quality, moisture control, and energy efficiency. Here are a few ways to flush out the building without mechanical ventilation:
Open windows: Open windows and doors to allow fresh air to enter the building. This can help improve indoor air quality and reduce moisture levels.
Natural ventilation: Use natural ventilation strategies, such as operable windows and skylights, to help flush out stale air and bring in fresh air. This can be especially effective in mild weather.
Passive solar design: Use passive solar design principles, such as orientation, shading, and thermal mass, to help control temperature and moisture levels in the building.
Air sealing: Seal the building envelope to prevent drafts and reduce air infiltration. This can help improve energy efficiency and reduce moisture levels.
Use exhaust fans: Install exhaust fans in kitchens, bathrooms, and other areas where moisture is generated to help remove humidity and stale air.
Use dehumidifiers: Use dehumidifiers to reduce humidity levels in the building, especially during summer months.
Use plants: Use plants to help purify the air and remove pollutants.
Regular cleaning: Regular cleaning and maintenance of the building can help improve indoor air quality by removing dust and allergens.
It's important to note that these strategies may not be sufficient to meet the needs of all buildings, and the best approach will depend on the specific building and the local climate. Building without mechanical ventilation can be problematic if not designed and maintained properly, it's recommended to consult with a professional to ensure the safety and comfort of the occupants.
