The UK Government has set challenging targets to reduce our production of greenhouse gases (the ‘net-zero’ challenge) as these gases cause the planet to warm and drive climate change. Homes play a large part in greenhouse gas emissions and in response, housing providers are making changes to homes to reduce household energy use. Local Authorities and private homeowners around the UK are adding extra insulation, reducing draughts and adding solar panels to make homes more energy efficient. We want to find out if these changes alter the amount of fresh air in the home or the health and wellbeing of residents.

We want to measure energy use, small inhalable particles, temperature, humidity and fresh air in our target households  before the energy efficiency building works are carried out. Technology is now available that we can do this with small, quiet monitors.
