The net effect of poor insulation levels, underheating and under-ventilation in buildings poses a major public health threat. Peter Rickaby describes one pioneering London project that’s taking a practical, methodical – and scalable – approach to solving the problem.

Dampness reduction via better ventilation seen to be key

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.

Swegon has launched its new generation WISE demand controlled ventilation system, which “represents over 15 years’ experience and the latest pioneering technology in demand controlled ventilation”.

Despite increasing standards of insulation and airtightness, housing developers face few requirements to provide better ventilation and indoor air quality for new home buyers — beyond knocking extra holes in walls. But as reports of condensation and mould affecting new housing developments continue to surface in both the UK and Ireland, and research indicates many new homes may have poor indoor air quality, are developers finally waking up to the need for properly engineered ventilation systems?

The National Standards Authority of Ireland has appeared to acknowledge a major discrepancy spotted by Passive House Plus in SR 54, its code of practice for the retrofit of homes, that could give rise to inadequate ventilation and poor indoor air quality in some dwellings upgraded to the code.

When Mike Jacob of Trunk Low Energy Building started planning to build this unique Essex home, it seemed likely to run way over budget, and still fail to meet the passive house standard. But rethinking key details and making tough compromises got the house within touching distance of passive, while slashing costs.

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?

.A range of newly certified passive house components were presented in January at the Deubaukom trade fair in Essen, Germany, including windows designed for use in the arctic and northern Scandanvia.  

The Passive House Institute has published a new study that looks at designing passive buildings for tropical climates. The study concludes that the key design criteria for such buildings include,"a very airtight building envelope, 10 to 15 cm of insulation, solar control glazing, fixed external shades for the windows and ventilation with both heat and energy recovery".
