Parallel Opening:
Review of Natural Ventilation Testing to prove the theory… Addressing new requirements Parallel Plus – The Features Dynamic Testing Summary

Benefits of Natural Ventilation: Occupancy Comfort Reduced Carbon Footprint Lower installation costs Reduced maintenance costs Smoke evacuation solutions Freedom of architectural design

So Why Parallel? Reflectivity High carrying capacity Provides occupant safety Balanced ventilation

Ventilation Formats: It has always been perceived that ventilation could be
achieved through the use of different opening methods with varying degrees of effectiveness.

Proving it: BRE Testing Test program commissioned at the Building
Research Establishment (BRE) to evaluate the various façade opening styles.

Air Flow Analysis: Top Hung High air speed within the room Low room temperature High draft risk 100mm opening required to
maintain ambient temperature

Air Flow Analysis: Top HungIncoming fresh air enters at a relatively high air speed resulting in large temperature differences and consequently high draft risk

Air Flow Analysis: Bottom Hung Low air speed within room In-effective air circulation Low draft risk 110mm opening required to
maintain ambient temperature

Air Flow Analysis: Bottom HungIncoming fresh air moves downwards, mixing with the warmer room air resulting in low draft risk but minimal air exchange

Air Flow Analysis: Parallel Very low air speed within room Effective air circulation Low draft risk 40mm opening required to
maintain ambient temperature
