As a Mechanical Engineer, it is surprisingly satisfying to design a ventilation system that doesn't need any ventilation equipment.

This is part of a natural ventilation system, with weatherproof security louvres backed with automatic Fire and Smoke Dampers.

The louvres allow outside air to come in during the summer to keep the space cool. During the winter the fire dampers are closed to stop too much cold air coming in and causing a condensation problem.

If the fire alarm goes off, the fire dampers automatically shut to stop fire escaping from the building.
