Manufacturing and commercial facilities

For medium to large-sized productive and commercial structures, green roofs provide numerous benefits, especially in terms of performance. The key point in this specific field of application involves the water cycle and issues related to hydraulic invariance. In the case of new constructions, urban planning regulations require consideration of the removal or reduction of previously permeable surfaces that will be rendered impermeable by the new structure. This is because the considerable areas that will be impermeabilized (roofs, asphalted areas for parking and maneuvering spaces, etc.) negatively impact stormwater management, increasing the volumes of water that urban drainage systems will need to handle.This issue can and must be managed consciously and carefully through the use of retention or storage tanks that contain stormwater from the new impermeable surfaces, slowing its release into drainage systems that may already be struggling. However, green roofs can play a key role since, as a technological system designed to intelligently manage received water, they help retain it within their layers, primarily in the substrate, slowing its release and, at the same time, reducing the amount of water to be disposed of. This thus makes it possible to reduce, in terms of volume, the capacity of the storage tanks leading to economic, logistical and clearly environmental advantages.

Having developed the individual elements that make up the green roof system, Harpo can provide runoff coefficients for various configurations, certified by the University of Genoa, facilitating the calculation for sizing retention tanks. Additionally, with the aid of the MediWaterSafe 4.0 controller, water consumption and overall water management could be further optimized.

Moreover, the use of greenery in these cases can also be considered an added value in terms of aesthetics and better integration of these structures within the territory, given that they are often concentrated in dedicated areas outside the urban center, without sacrificing a low level of maintenance, which is fundamental in such a context.
