Zehnder launches MVHR system for tight spaces

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.

Good design key to heating & cooling via MVHR – CVC Direct

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.

State-of-the-art heating test lab opens at GMIT

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.

MVHR owners sought for air quality study

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.

MVHR myths still persist — CVC Direct

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.

The PH+ guide to heat recovery ventilation

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.

Understanding enthalpy heat exchanges for MVHR

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.

BEAM announces passive house cert for MVHR system

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.

Understanding SFP crucial to MVHR choice — CVC Direct

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.

Brink launches new MVHR unit with range of features

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.

Fresh-r wins passive house component award

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.

Airflow adds VAV control to its commercial MVHR range

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.

Ireland's first passive house pharmacy

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.

Ledbury passive house embraces warmth, wood & light

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.

Natural ventilation - does it work?

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?
