The new Brink Flair 225 heat recovery ventilation unit from Brink Climate Systems has officially been released.
Beam Vacuum & Ventilation have launched their new range of HERU heat recovery ventilation systems, combining a sleek new design with award-winning rotating heat exchanger technology.
Built Environment Technology Ltd are supplying an innovative MVHR system with geothermal intake ducts at a luxury new-build home for a private client and his family, in Surrey.
An international standard ‘E-Thermal’ environmental test facility designed to assist Irish SMEs in developing new sustainable heating products has formally been opened at Galway Mayo Institute of Technology.
Green Building Store and PHI Architecture are currently seeking property owners with MVHR systems to take part in air quality research in conjunction with Nottingham University.
Heat recovery ventilation is an invaluable way to maintain indoor air quality in low energy buildings and minimise the loss of precious heat, but there are several issues to address to ensure optimal performance. Ventilation expert Ian Mawditt, a technical advisor on Part F of England’s building regulations, has decades of experience in field investigations of indoor air quality and ventilation effectiveness. His guide, which focuses on centralised or ducted whole house heat recovery systems, is essential reading to anyone considering such a system.
NIBE’s F730 exhaust air heat pumps have been selected to provide heating, ventilation and hot water for the Bolands Quay apartment development at Grand Canal Dock in Dublin, which is currently under construction.
Industry-leading mechanical ventilation company Beam Vacuum & Ventilation has announced their Axco HERU 100T mechanical ventilation with heat recovery (MVHR) unit is now a certified passive house component.
One of the key elements that influences choice of mechanical ventilation with heat recovery (MVHR) units is specific fan power (SFP), says leading MVHR supplier CVC Direct. The basic principle of the passive house standard is to reduce energy demand, and SFP is a key indicator for measuring the energy efficiency of the MVHR unit. The lower the SFP, the more efficient the system.
Leading mechanical ventilation with heat recovery (MVHR) manufacturer Brink Climate Systems has launched a new high efficiency MVHR unit, the Flair 325. According to the Dutch company, the new range comes with some exciting new technologies to boost efficiency, ensure correct ventilation rates and enable easy operation.
The Dutch company Fresh-r has won the passive house components award at the 22nd annual Passive House Exhibition in Munich, for its decentralised residential ventilation system. Fresh-r worked together with the Scottish firm Collective Architecture on its submission for the award, which was presented at this year’s international Passive House Conference.
Leading low energy ventilation supplier Sustainable Homes Scotland has advised anyone carrying out a deep retrofit — or building a small low energy dwelling — to consider the benefits of a new generation of decentralised mechanical ventilation with heat recovery (MVHR) systems.
Leading ventilation manufacturer Airflow Developments has added variable air volume (VAV) dampers to its Duplexvent range of commercial mechanical ventilation with heat recovery (MVHR) units. The VAV systems constantly monitor the air volume supplied and share this information with the ventilation unit. As such, the systems ensure optimum air quality and comfort by allowing the ventilation to respond effectively to the demands of each area of the building.
At first glance, designing out electrical fans from ventilation strategies may appear attractive, and even sustainable. Simon McGuinness offers some home truths.
Investing in heat recovery ventilation units without paying due attention to distribution systems may risk undermining energy performance and indoor air quality, a leading ventilation expert has warned.

Late last summer, work finished on architect Paul McNally’s latest super low energy project: a three-storey building in Tipperary that has just become Ireland’s first certified passive house pharmacy.
For Ruth Busbridge and her builder Mike Whitfield, aiming for the passive house standard was just one part of an environmentally conscious approach that put natural, healthy materials to the fore.
Such is the importance of ventilation, it’s only right and proper that the efficacy of innovative mechanical solutions such as heat recovery ventilation and demand controlled mechanical extract ventilation is established
based on robust, comprehensive evidence. But how does natural ventilation fare when subjected to the same degree of scrutiny, and can it work in low energy buildings?
