Economic Benefits

Extended roof life

Green roofs have been shown to triple the life 
expectancy of the roof. 
The underlying roof materials are protected 
from mechanical damage, ultraviolet radiation 
and extreme temperatures, which results 
in reduced maintenance and renovation costs.

Energy efficiency

Green roofs help to reduce energy 
consumption by 40% for heating in winter 
and by 100% for cooling in summer. The performance depends on several aspects including climate conditions, type of construction, thickness of insulation…

Noise reduction

A green roof system provides good 
sound insulation, keeps the living 
space quieter and creates more 
pleasant surroundings in urban areas. 
It contributes to noise reduction in large cities, 
near industrial areas and airports.
