free cooling of buildings
- cooling by evaporation
- additional thermal insulation during dry spells
extended life of the roof
- high physical protection
- protection from UV radiation
- balance of extreme temperatures
- reduction of kinetic energy
increased efficiency of photo voltaic systems
- no-vegetation-zone around the photo voltaic system prevents shadows
- evaporative cooling increases panel efficiency
water retention systems
- reduction in size or omission of space-consuming infiltration systems
- unused earth is available for future use
reduction of pipe cross sections
- optimized thicknesses
- improved use of space
reduction of fees
- due to less water released
influence on the structural engineering
- dry weight (excluding substrate): ~ 2.5 kg/m²
- VIRIdiVITA substrate (wind erosion stable): ~ 90 kg / m²
fast installation / fewer work steps
one work step (instead of three):
- physical protective layer
- drainage layer
- retention layer
