Zehnder Group UK has launched the Zehnder ComfoAir Flex – a mechanical ventilation system with heat recovery (MVHR) specifically designed for tight spaces and challenging installation environments.

SAV Systems has announced that the AirMaster AM 1000 has been awarded passive house component certification in conjunction with the company’s Danish partner, Airmaster A/S.

The new Brink Flair 225 heat recovery ventilation unit from Brink Climate Systems has officially been released.

The new Beam VentSmart app for the Axco Counterflow range of MVHR units is now available. Beam said that the app has been designed to make control of its heat recovery ventilation systems as easy and straightforward as possible.

A big part of a comfortable household is having good indoor air quality and a comfortable air temperature. Mechanical ventilation with heat recovery (MVHR) is an efficient way of providing the necessary ventilation with little heat loss.

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.

The idea that mechanical ventilation with heat recovery (MVHR) systems are designed to provide heating or cooling remains a common misconception about the technology, according to leading supplier CVC Direct.

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.

A luxury new development in an exclusive Dublin location will achieve nearly zero energy building (NZEB) standards with help from Daikin Altherma air-to-water heat pumps and a highly energy efficient building fabric.

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.

Leading mechanical ventilation with heat recovery (MVHR) supplier CVC Direct believes that despite the growing popularity of MVHR, there are still many misconceptions about the technology among both general consumers and the building sector.

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.

Leading ventilation supplier CVC Direct has advised anyone specifying an MVHR (mechanical ventilation with heat recovery) system to understand the basics of relative humidity and consider their own local climate before choosing a system with an enthalpy heat exchanger.

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. 

In this blog post, David McHugh of Irish heat recovery ventilation manufacturer ProAir recalls the story of the company, from its foundation in his spare bedroom right up to its recent passive house certification 

Leading Irish heating supplier Origen Energy has launched the Genvex Combi 185 combined heat recovery ventilation and domestic hot water heat pump to the Irish market.

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.

A new development in Tipperary aimed to combine excellent levels of airtightness and insulation with generous glazing and natural ventilation to deliver ultra-modern, comfortable, low energy offices. How did it work out?

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?
