When it comes to MVHR, size does matter, according to leading system designer and supplier CVC Direct.

A new report by the Passivhaus Trust has questioned the common assumption that mechanical ventilation with heat recovery (MVHR) is inappropriate in dwellings with air permeability worse than 3 m3/m2/hour.

Leading ventilation supplier Solarcrest has advised anyone specifying a mechanical ventilation with heat recovery (MVHR) system to ensure it is properly designed to deal with local air pollution issues.

Green Building Store has announced the launch of a new service that is now included at no extra charge in its product packages.

VentHeat, a new Irish company specialising in heating, ventilation and air conditioning systems for passive house and low energy buildings, has launched the Pichler PKOM4 compact heat pump system to the Irish market. The system combines heating, cooling, ventilation and domestic hot water in one passive house certified unit with a footprint of less than 0.75 m2.

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.

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.

Industry-leading mechanical ventilation company BEAM Vacuum & Ventilation has introduced a new user-friendly, high specification digital control panel for their popular Axco C130 Counterflow MVHR system. The aura-t wall mounted panel offers an advanced yet simple-to-use touchscreen controller for programming, commissioning and occupancy control.

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.

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.

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.

Prefab passive house specialists naked house Ltd recently completed the installation of a fully integrated passive house services system at their Marsh Road project in Shropshire. MVHR and solar thermal system are a standard part of the naked house system, with extra optional modules to enhance the building’s potential to save the occupants’ running costs. At Marsh Road, this included a log burner, thermal store and central logic control system. 

New evidence indicates that decentralised MEV systems – an increasingly popular option, now questions are being raised over the standard “background-plus-intermittent extract” ventilation strategy – can also fail to provide adequate indoor air quality, and may even perform worse than the standard approach in new build homes. 

Saffron Acres is a social housing development in Leicester that is set to be the largest affordable passive house scheme in the country.

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 

Nilan Ireland has announced that all Nilan heat pumps have achieved best-in-class performance under the EU’s new Ecodesign Directive, which came into force last September.

Flynn Heat Recovery Systems has just completed the installation of 93 Zehnder passive-certified MVHR units in a housing scheme under development by SDR Group at Aikens village, Stepaside, Co Dublin.

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?

Tina Holt had experience advising homeowners on energy efficiency, so when she wanted a low energy home, buying a run-down 1950s dwelling and aiming to turn it passive was an obvious step. She tells her own story below.

Energy efficiency expert Mark Shirley of 2eva.ie has just completed a whistle stop tour of ISH in Frankfurt, one of the world's largest building industry expos, where he found passive house solutions featuring heavily amonst the heating and ventilation solutions on offer.
