Green roof: garden in the home roof

Green roofs improve air quality, reduce noise and improve the thermal insulation of buildings, resulting in a reduction of impact energy and UV rays and high temperatures.

Green roofs are a solution to the loss of green areas in urban areas. They are also aesthetic and environmental benefits generated.
They can also become alternatives to complement our food.
Some important considerations:

energy conservation

• Can reduce heating and cooling requirements by 20 to 30% for one-story structures.
• Reducing energy consumption: a fall of between 2 and 4 degrees, it can translate into 10% less air conditioning consumption
• Absorbs less heat, a green roof can not be heated beyond 25-30 degrees, while a conventional roof can be heated to 62 degrees celcius
• Improving the insulation capacity of building envelope

extends the life of the roof

• Packages of roof vegetation holding last up to twice over a conventional roof. the life of the waterproof membrane (common for all ceilings) can reach 40 or 50 years
• Life expectancy of the membrane increases due to the protection of vegetation against variations in temperature, UV and mechanical damage.
• Reduce the impact of UV rays and high temperatures on areas surrounding the building

noise barrier

• Reduces noise insulation requirements
• Rather than reflect, absorb noise

stormwater control

• Holds between 50 to 70% of rainwater falling on the roof, and increased evapotranspiration rates
• Reduce pollution of groundwater and flood control effects on rainwater collectors, and sites with high groundwater

environmental factors

• Helps to cool the air and reduce the “heat-island effect of urban”
• Eases smog levels by capturing particulate matter floating
• Absorbs carbon dioxide levels in the atmosphere
• Forms a natural habitat for insects, birds and vegetation
• Produces oxygen. square feet of green roof produce enough oxygen for one person for a full year

cost reduction over the life of a roof

• Decreased levels of maintenance and repair costs and replacement of materials
• Provides opportunities for cost reduction on municipal system rainwater collectors, and in some countries, tax exemptions

ecological restoration (or the right to park)

• Improving the use of property and constitutes a natural area subsitute previously sacrificed
• Offers additional alternatives for open green spaces in areas of high urban density
• Offer points of ecological connectivity within the city for species that migrate through it
