What is being as described as an innovative approach to a tried and tested method of ventilation being introduced by Passivent. The company says it is set to further improve the internal living environment by cutting condensation risk. One of the UK’s leading suppliers of ventilation solutions, Passivent has developed a ductless ‘whole house’ Positive Input Ventilation (PIV) System, to effectively ventilate the home, cut condensation and minimise energy consumption. The system, which is easy to install, overcomes the problems normally associated with accommodating ducting in existing properties, making it particularly suitable for refurbishment projects.

All the rental and affordable homes in a major development in Peckham feature Passivent's mechanical extract ventilation system (MEV) using a fan per dwelling design.

The MEV uses a remotely located central extract fan to remove the stale, moisture laden air from 'wet' rooms (bathrooms and kitchens) through ceiling or wall mounted extracts. Passivent Flair additionally incorporates a stylish Italian designed cooker hood into the MEV system to provide a whole apartment ventilation system.

Developed as an ?environmentally responsible? design and construction in non-domestic buildings by the Welsh Development Agency, Dyfi Eco Park features trickle vents from Passivent. The development, near Machynlleth, is being built with sustainability at the forefront of the design brief, which included using renewable energy such as making use of natural ventilation. Passivent proposed the use of trickle vents in the window frame heads of the study rooms to provide discreet background ventilation accompanied by passive stack ventilation (PSV) of the sanitary accommodation. The trickle vents provide a flow of air into the building, directed upwards to reduce the risk of draughts. Vented out through the roof, the PSV system removes ?used? air through extracts linked to ducting.
