Dwell-Vent is a revolutionary approach to the ventilation of houses and flats, with substantial benefits:
Energy savings - The 'supply-air' window used in the Dwell-Vent system leads to energy savings amounting to 10% - 20% of household fuel bills.
Comfort - The air entering rooms is pre-warmed in winter to avoid draughts and make rooms feel comfortable.
Health - The provision of reliable and generous levels of ventilation avoids problems of mould growth and other allergens detrimental to health.
Passive operation - The system functions without the input of electricity or any moving parts resulting in low running and maintenance costs.
Sustainable - As well as reducing household energy bills Dwell-Vent windows are manufactured from sustainable timber, lowering the embodied energy of the system.
Economic - Based on estimtes at the now completed Mater Orchard project in Ireland, Dwell-Vent, in conjunction with other low-energy technologies, adds only 5% to the cost of a project, whilst delivering a 50% reduction in energy demand.
For the succesful implementation of a Dwell-Vent system, certain basic criteria have to be met:
The system requires at least two window lights in each habitable room with a minimum width each of 635mm (the odd exception is allowed) and maximum height of 1500mm.
The building configuration must allow passive stacks to run from the wet rooms straight upto the roof, including from downstairs WCs.
The dwelling should be made airtight, in the region of 3ACH@50Pa.
