E-stack Ltd Products

The e-stack^® natural ventilation system uses technology patented by the University of Cambridge which is designed to ensure a minimum rate of air change between a building and the exterior in Winter to comply with Part F of the building regulations, whilst minimizing the heating energy required. The system ensures that the air quality remains very high but also that the building is totally comfortable to avoid the risk of cold draughts which are often associated with natural ventilation systems.

The new technology provides a solution for maintaining comfortable indoor tempertaures while reducing the use of building heating systems compared with other solutions, as shown on the graph below.

In warmer weather the system typically operates with higher ventilation flow rates in order to minimize the risk of overheating, although it can be used in conjunction with thermally massive building types to exploit the benefits of passive night-colling in which case lower ventilation rates are again used.

For more details, see the examples listed here.

Data collected at Harston School in Cambridgeshire shows how the e-stack^® system provides a much better quality environment in winter.
