Download the document for calculation of constant airflow necessary in a household.

Both single-family homes and blocks of flats must have means so that their enclosures can be adequately ventilated, eliminating the pollutants that usually occur during normal use and providing a sufficient flow of outside air to ensure the extraction of contaminated or stale air .

The calculation of the extraction flow for a house will be based on the number of wet rooms (bathrooms and kitchen) and the dry ones (living room or dining room and bedrooms). The CTE (Spanish technical building code) establishes minimum flows in the basic HS Health document, specifically in section HS3.

Casals has a wide range of fans for residential ventilation that you can borrow on this document.
