Energy efficiency requirements
The rigours of modern life mean we may spend around 90% of our time indoors. Sadly however, the air in our homes can be up to 5 times more polluted than the air outside.
As UK homes become more airtight due to energy efficiency requirements, accumulated pollutants are being prevented from escaping. The concern for indoor air quality is increasing, not least because poor indoor air quality is linked to a host of serious health conditions and loss of life.
