In the last 25 years, the number of new asthma cases in the UK has increased six fold among children and three to four fold in adults. Asthma now affects more than five million people in the UK and kills 1,500 a year. Poor ventilation causes high levels of humidity which in turn increases the levels of dust mites - a known trigger for asthma. As we build tighter homes and continue to ‘seal up’ existing ones the requirement for good ventilation is becoming paramount.

In order to address climate change, the UK Government has reacted strongly to enforce stringent legislation to achieve an 80% reduction in greenhouse emissions by 2050. As 25% of carbon emissions come from homes and a further 17% from non-domestic buildings, every household and business, both public and private must increase their energy efficiency levels, meaning an update to the domestic building services compliance guide.

For property-owners interested in implementing MVHR, there are a number of things to consider as you plan and install your system.

Paul Croughan, National Account Manager at EnviroVent looks at the challenge facing specifiers of how to effectively lower a property’s Dwelling Emission Rate (DER).

Imagine if there was a whole house ventilation system that not only reduced humidity levels, but also had the ability to provide efficient perception cooling into your home during warmer weather.
