1. The specific demonstration project will help the assessment whether or not photocatalytically active construction material may be a technology for achieving better indoor air quality throughout Europe.

2. VISIONS will prove that it could provide the basis for a European Directive on the usage of photocatalytically active construction materials in Europe. Consequently, it represents an opportunity for the development and implementation of a new de-polluting European strategy.

3. Furthermore, an update of the EU legislation could be achieved based on specific actions of the project which will create policy recommendations.

4. As far as the energy sector is concerned VISIONS contributes to the implementations for energy efficient buildings through the rational use of ventilation systems as a result of photocatalytic activity of indoor building materials.
