RoofGreen - Let's make the world greener
Environmental advantages
The Environmental advantages in selecting a Green roof are considerable:
ENERGY REDUCTION
A Green roof provides increased Insulation and does not only reduce building heating and air conditioning costs, but this reduction reduces CO2 and energy requirements.
TEMPERATURE REDUCTION
The temperature in a city in summer can be 5 degrees higher than in the countryside.
This is caused by the absorption of heat and
heat gain through buildings and roads. Green roofs reflect heat and
planting varieties cool the air through perspiration.
C02 ABSORPTION
The vegetation and planting varieties of a Green roof absorb C02 gases and produce oxygen.
MICRO LIFE AND ECOLOGICAL RECYCLING
Building activities badly disrupt micro organisms and habitats for many animals and birds. Green roofs help restart Micro life and the
ecological recycling of the buildings footprint. Green roof vegetation
provides a natural habitat for Insects, attracting birds and sustaining
wildlife.
RAIN WATER RETENTION
Heavy rainfall is an increasing problem globally, causing rivers to overflow and drainage systems to fail. With a 50% water retention
and even water recycling options, green roofs can considerably
reduce the environmental impact of a new building, particularly
when the new building has replaced an open area.
WATER PURIFICATION
The excess rain water that drains from a green roof has to filter
through the plant and substrate layers to reach the outlets. By doing
so, rainwater is purified of lead, copper and cadmium that is carried
in the rainwater. Approximately 95% will remain in the soil
substrate including approximately 19% Zinc and traces of nitrogen.
This filtration process provides cleaner rainwater in to the drainage networks.
