How do green roofs change the thermal balance indoors?

One of the environmental impacts of poorly planned urbanisation is the reduction of green areas in urban centres. The green roof has been presented as one of the alternatives for reducing this negative environmental impact. But what are the advantages and disadvantages of implementing a green roof? Although this technique has received more attention in recent years there are still few scientific studies that present quantitative and qualitative data on the subject. This work presents a fully applied case study verifying the impact of a green roof on the variation of internal temperatures in an environment designed specifically for this purpose. A second prototype identical to the first does not receive the green roof and has its temperatures monitored simultaneously allowing a comparison based on experimental data.
