CEN/TR 14788 : Ventilation of buildings - Design and dimensioning of residential ventilation systems.

This document provides recommendations on the design and performance of ventilation systems serving single-family homes, multi-family dwellings, and apartments, in both summer and winter. It is intended in particular for architects, designers, builders, and those responsible for applying regulations and standards. It covers natural ventilation, fan-assisted supply, extract, and balanced ventilation systems, as well as combinations of these, for individual or central systems. Systems combining ventilation with heating and/or cooling are also included. Ventilation of garages, common areas, roof voids or raised-floor voids, wall cavities, and other structural spaces is not covered. The effects of radon and other soil gases, as well as systems designed to reduce their entry, are excluded.
