Maximum daylight and ventilation are preconditions to ensuring optimal indoor
comfort and minimal energy consumption consistent with the standards of the future.
In a world with increasing health problems (partly due to the rise in incidence of allergies, for example), the indoor climate is an essential factor to be considered when designing a house.
Several studies document that daylight has a positive effect on health, productivity, children’s learning abilities and general well-being. Similarly, fresh air via natural ventilation is vital for producing a healthy indoor climate, reducing the consequences of toxic emissions from sources such as electronic devices and chemicals in the home – and thereby minimising the risk of allergies.
In the EU today, we spend 90 % of our time indoors. But up to 30 % of the building mass neither contributes to nor provides a healthy indoor climate. We each consume an average of 2 kg of food per day and breathe 15 kg air per day. So the quality of the air in the rooms that we occupy is of great importance.
