The growing demand for low-energy buildings has added to the pressure on engineers and manufacturers charged with producing effective ventilation systems for schools. Many new classrooms are planned under the Building Schools for the Future programme in England, and this has only increased the need for novel approaches. The e-stack ventilation method, developed over two years, provides a low-energy system based on the principles of natural ventilation to minimise the fan power used to bring air in and out of a building.
