Resumen:
This document applies to the design and installation of natural
smoke and heat exhaust ventilators (NSHEVs) for spaces from which
smoke is extracted vertically by thermal buoyancy via the roof in
the case of single-storey buildings and via the uppermost storey in
the case of multi-storey buildings. It also applies to spaces in
which NSHEVs are installed in external walls.
This document includes tables and calculation methods for the
design of clear layers in order to comply with the requirements of
various protection objectives.
This document includes information and provisions to be taken
into account when applying the design rules set out herein and when
installing NSHEVs.
