| Resumo: | The benefits of using housetops as green roofs are already well known both in building scale as well as in city scale. It is interesting to consider the characteristics of flexibility and practicality of implementation and maintenance of extensive modular green roof. It is also noteworthy when used materials are consistent with environmental sustainability proposals. From this perspective, one can highlight the use of lightweight concrete made from footwear industry waste to produce the modules to receive vegetation. Considering this type of green roof (extensive) and the materials used in the modules (precast cement elements with EVA waste), this article presents a study that attempts to identify the benefited biodiversity and the interactions between the modules and the plants on it. The above mentioned green roof was built over the standard roof of an existing building in the laboratory and it was monitored for nine months, under a hot and humid tropical climate condition. Results showed that several cultivated medicinal plants (herbaceous size) have adapted well to the material and module design, particularly in relation to the spaces of the cells within the modules, which only require monthly maintenance and irrigation 3-4 times per week, in low rainfall period. Several kinds of animals (worms, cockroaches, millipedes etc.) and invasive plant species were found in the micro-habitat, confirming the hypothesis that such an environment assists in maintaining biodiversity. |
