One of the primary concerns when building new homes today is energy efficiency. This can be achieved by using many different techniques, including making them more airtight.

Good ventilation is essential in enclosed areas where people live and work, and the heat recovery element of the system can help to improve energy-efficiency.

There are many issues to consider when you are thinking about building your own home but ventilation shouldn’t be an afterthought when planning a self-build.

Whether planning a self-build project, undertaking a renovation, or working as a contractor or other professional in the construction industry, you must ensure that any work you plan to undertake or commission complies with the relevant building regulations.

All homes need adequate ventilation and incorporating mechanical ventilation with heat recovery (MVHR) into your house-building project could provide the perfect solution.

A recent survey of 200 homeowners who had bought a ventilation system from EnviroVent revealed how over half of these householders had experienced improvements to their health or home within two weeks of its installation.

Ahead of this year’s event on 21 June, Global Action Plan, the organisation behind Clean Air Day, has launched a campaign highlighting the dangers of indoor air pollution. When thinking of air pollution, most of us probably think about traffic and industry belching out thick black fumes but indoor air pollution is an invisible danger.

Air pollution is a major problem throughout the UK and beyond, causing harm, and even death, to thousands of people each year. But, Clean Air Day, which this year takes place on 21 June, aims to raise awareness of the problem as well as encouraging people to take simple steps to reduce the pollution they create.

The annual event, Clean Air Day, takes place on 21 June. Organisers are urging people to leave their cars at home for the day after pollution-busting data gathered on the day of the London Marathon showed a huge drop in air pollutants during the largely traffic-free day.
