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.

Integrated passive services installed at Shropshire naked house scheme

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 research reveals high failure rate for ventilation systems

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. 

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?

Nottingham upgrade achieves dramatic energy savings

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.

Passive house asserts itself at Frankfurt trade fair

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.
