Parallel Plus Explained
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.
Proving it: BRE test facility
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
Air Flow Summary: Parallel‘It is clear that a Parallel opening vent provides a good configuration for natural ventilation with unconstrained inlet and outlet flow paths’Ref. BRE Report No. 239-111 August 2007.
Parallel Windows Must: Maintain parallelism Offer increased carrying capacity Incorporate low operating forces Provide proven endurance
Parallel Plus: the benefitsNew features provide consistent parallel operation
Parallel Plus: Manual OperationDesign changes now allow vents up to 200 Kg to be operated manually negating the use for synchronised motors.
Parallel Plus: Resistance to RackingUn-affected by lateral wind speeds of up to 60 mph.
Parallel Plus: Resistance to Gust LoadingTested to withstand positive wind loads of 100mph.
