Having rooms that feel good isn’t just a superficial luxury – home comfort has a huge impact on health and psychology, and ensuring that your loft conversion is healthy is an essential part of green building.

“Sharp distinctions between health and comfort are not always readily apparent and may not be approrpiate” – Ted Schettler, Science Director of the Science and Environmental Health Network 


Temperature, humidity, lighting, noise, chemicals, and smells all contribute to the comfort of your home and define how well you can relax, sleep, and breathe while indoors. A major aim of green building is to use less energy to maintain constant temperatures and good ventilation while reducing the number of harmful toxins or chemicals used during construction.

4 Main Factors in Designing a Healthy Loft Conversion

Health factors, environmental factors, and budgetary factors all play a part in designing a health loft conversion, and often focus on the same items. Mould growth and moisture accumulation, for example, are detrimental to health and extremely costly to deal with. Green design focuses on using materials that prevent moisture build up and save you and your family from having to deal with a persistent mould problem in your loft.

There are 4 main factors in designing a loft conversion with food indoor air quality:

  1. Source control: reducing the pollutants introduced to the home through building or cleaning materials
  2. Ventilation: allowing air to flow in and out of the building to control humidity and reducing the build up of pollutants
  3. Commissioning: creating specifications before building and working to ensure that the build follows the requirements set out at the beginning of the project
  4. Maintenance: ensuring that the building is kept clean and maintained properly

Green Building Materials

Eco-friendly building materials reduce your impact on the environment, but also use materials that are more conducive to good health and good home comfort. Using timber rather than plastic, for example, allows for better ventilation and introduces fewer chemicals into your home. It also doesn’t act as a vapour barrier, so you won’t experience humidity build up and condensation that can lead to mould in the UK.

Green loft insulation is another way to improve the comfort in your home by reducing the amount of energy wasted while maintaining a constant indoor temperature. Rather than using harmful substances like fibreglass, green loft insulation is made from organic substances and often recycled materials.

Green Cleaning

The last item on the list is maintenance, and refers to how you clean and manage your home well after the loft conversion has been completed. Reducing the number of chemicals used in the home improve breathing and even improves children’s immune systems by exposing them to bacteria and ensuring their bodies know how to fight off infection effectively.
