Green Roof Embodied Energy

This value is equivalent to 6448 g c m 2 which is significantly greater than 378 g c m 2.

Green roof embodied energy.

With energy costs continuing to rise the popularity of green roofing systems is also on the rise. An airtight sip building will use less energy to heat and cool allow for better control over indoor environmental conditions and reduce construction waste. Our one square foot patch of green roof will save about 1 000 btus per year in cooling energy which means that it will take about 40 years to recover the process embodied energy of the green roof. Cooler than cool roofs.

By comparison a cool roof on this building will save about 700 btus per square foot per year. Concrete has a lower embodied energy but greater toxicity in its emissions. The embodied energy for green roof components are 23 6 kg m 2 5 pounds per square foot co 2 of green roof. 71 73 compared to clay tile or concrete roof covers through ongoing encouragement of recycling strategies and increased local recycling facilities able to embrace residual cradle to cradle material reuse.

Both sod roofs and lwa based lightweight aggregates roofs have been found to have a negative impact on the quality of their resulting runoff. Structural insulated panels sips are one of the most airtight and well insulated building systems available making them an inherently green product. The main pollution issues with steel roofing are the dioxins produced during smelting and the pollutants produced in the manufacture of the usual pvc. By providing focused leadership and technical execution from our vast network of experience grc assures your energy solution is achieved with.

Findings confirm that a sheet metal roof can obtain significant carbon and embodied energy saving benefits i e. However when you do the sums you find that the waterproof membrane beneath the living roof may well contain the same embodied energy as the tiles because of the high energy oil based material it is made of. According to the us dept of energy the average american household releases about 2 tons of carbon dioxide into the atmosphere as energy is consumed each year. It has also been reported that homeowners spend upwards of 11 billion dollars a year to.

Though the embodied energy is high there are few toxicity issues involved in the manufacture of clay tiles.
