Extensive wild meadow

THIS IS A SYSTEM THAT FINDS TYPICAL APPLICATION IN LARGE INDUSTRIAL OR COMMERCIAL BUILDINGS, IN AREAS WITH HIGH SOIL SEALING AND IN NEED OF REDEVELOPMENT FROM A NATURALISTIC AND LANDSCAPE POINT OF VIEW, BUT ALSO ON WINE CELLARS AND BUILDINGS OF VARIOUS KINDS SET IN A VALUABLE LANDSCAPE AND NATURALISTIC CONTEXT, SERVING THE FOLLOWING FUNCTIONS:BRING GREAT NATURALISTIC VALUE, AIMED AT THE CONSERVATION OF FAUNA AND FLORA

SERVE AS AN IMPORTANT MEANS OF INTEGRATION WITH THE SURROUNDING NATURAL LANDSCAPE
PROMOTE THE RESTORATION OF THE WATER CYCLE, IMPROVING MICROCLIMATIC CONDITIONS AND PROMOTING AIR PURIFICATION
EXTEND WATERPROOFING LIFESPAN
CONTRIBUTE TO PASSIVE COOLING OF THE BUILDING DURING THE SUMMER MONTHS AND IMPROVING WINTER INSULATION

HARPO EXTENSIVE WILD MEADOW SYSTEM FEATURES

The Harpo verdepensile extensive natural meadow system adheres to the UNI 11235:2015 standard, ensuring and exceeding the minimum characteristics for both individual elements and system performance.

The main features of the system are as follows:

Versatile and lightweight: usually the thickness of the system varies from 15 to 18 cm for the BAS line and from 17 to 20 cm for the RIC line. In both cases, the maximum retention weight of the lower thickness system starts from 150 kg/sqm
Aesthetic value: through the creation of a complex and balanced phytocenosis, a dynamic ecological balance is established on the canopy that increases the stability of the greening. Plants are highly competitive and leave little room for weeds. It represents the closest solution to the characteristics of Mediterranean nature and is characterized by high biodiversity and resilience.
Usability: limited, the morphology of these plants lends itself little to free enjoyment. Given the variability of habitus throughout the seasons, however, it provides high visual usability and psychological benefits.
Management costs: maintenance is very low. Depending on the case, one or two mowings per year are to be expected, carried out with a tiller or brush cutter. Such interventions are, however, no more costly than weeding done by hand.
Irrigation: it is mainly for emergencies, the vegetation has good drought resistance and high regermination capacity.
Implementation costs: this solution is particularly economical due to the low cost of implementation, seeding and maintenance and is therefore very suitable for the greening of large areas.
Thermal resistance: the system contributes to energy savings with a thermal resistance that varies depending on the water content but is not less than 0.48 (m2 * K)/W, with substrate thickness 12 cm, according to the NRC report for the BAS system.
Runoff coefficient: variable depending on substrate thickness, actual values can be provided upon request based on studies conducted with the University of Genoa and in our laboratory.
