Interactions between factors and potential risks need to be considered holistically:
- bio–psycho–social aspects of health;
- interaction between inhabitants, buildings, and the indoor environment;
- occupant´s understanding about building systems and functionality;
- climate change and its impact on indoor environment quality, thermal comfort and health;
- and measures in the fields of energy-efficiency, indoor environment and design to achieve good indoor environment.
A new future could be in control (having or not having control) over indoor climate because modern buildings are becoming more flexible. For example, recent developments in personal ventilation systems and local climate control systems seem to open up promising alternative paths towards better and adjustable indoor climates in buildings. The flexibility of building systems also increases the value of buildings and their energy performance.
To reach the indoor air quality, where even the most sensitive people find the air acceptable, will require a future paradigm shift. Further paradigm shift is foreseen when people will learn how to treat indoor air, so it is perceived as equally pleasant and fresh as outdoors when it is best, for example in the mountains or by the sea. And even another shift may be in creating indoor air that is even better than anywhere in nature!
