Study of green roofs aplications in order to deliver buildings neutral carbon

Abstract

In the context of climate change, the industrial sectors have been involved in mitigation and neutralization programs of emissions of greenhouse gases (GHGs). One way with the construction industry has to "neutralize" some of their emissions is to transform the building in carbon sinks through the implementation of "green roofs," which consists of the vegetation growing on land substrates on the roof of buildings. It happens that this deployment adds load to the building structure, with the need for this to be strengthened. This work, through a study of representative case, helps to examine whether the addition of CO2 emission resulting from the structural reinforcement is less than the carbon stored in the "green roofs", verifying the feasibility of the this technique in this regard. The study showed that for the case study, this deployment has very positive balance as CO2 emissions by storing more carbon than emitting and can significantly neutralize the emissions from the construction work.
