Tree intensive

THE SYSTEM IS USED ON ROOFS OF UNDERGROUND SPACES SUCH AS GARAGES OR INFRASTRUCTURE. IT IS ALSO USED ON TERRACES, TO A LIMITED AND PUNCTUAL EXTENT DUE TO THE HIGH LOADS. TREES ALLOW TO PLAY WITH LIGHT AND SHADOW, SOLIDS AND VOIDS AND TO PLACE SCREENS THAT INCREASE THE PRIVACY OF THE GARDEN AND CREATING VIEWS AND PERSPECTIVES TO DILATE THE PERCEPTION OF SPACE. IT IS SUITABLE FOR SMALL PRIVATE AREAS AS WELL AS LARGE PUBLIC GREEN AREAS. FRUIT TREES ARE ALSO SOMETIMES USED.

THE GREEN ROOF SYSTEM SERVES THE FOLLOWING FUNCTIONS:

USE TREES FOR VARIOUS ECOSYSTEM PURPOSES OR SIMPLY TO GIVE COMPLETENESS AND A PERSONALIZED TOUCH TO THE GARDEN. ROOFTOP GARDENS ALSO OFTEN ENJOY MUCH GREATER PRIVACY THAN THOSE ON THE GROUND.
MITIGATE THE HIGH TEMPERATURES OF BOTH THE SPACES BELOW THE ROOFTOP AND THE ADJACENT OUTDOOR ENVIRONMENT DUE TO SUBSTRATE THICKNESS AND INTENSE EVAPOTRANSPIRATION.
CONTRIBUTE TO THE STORAGE PROCESS IN THE CASE OF INTENSE RAINFALL AND PROMOTE THE RESTORATION OF THE WATER CYCLE.
LOCALLY PROMOTE AIR PURIFICATION.
EXTEND THE LIFE CYCLE OF WATERPROOFING.

HARPO INTENSIVE SYSTEM FEATURES FOR SECOND AND THIRD SIZE TREES

The Harpo green intensive tree system adheres to the UNI 11235:2015 standard, ensuring and exceeding the minimum characteristics for both all individual elements and system performance.

The main characteristics of the system are as follows:

Aesthetic value and usability: a tree intensive is used in a complementary way to lawn and hedge covers. In more articulated gardens it allows the creation of enclosures and views of greater landscape value. The possibility of creating a true urban forest, it complements the new ecosystem performance trends required of urban greenery.
Management costs: trees require few infrequent, but skillful and targeted interventions. The frequency of interventions is dependent on the type of vegetation.
Irrigation: vegetation requires a moist substrate and therefore a calibrated irrigation system should be designed.
Implementation costs: this solution is rather expensive because of the high thicknesses. The total cost is functional to the type of plants used and from the planting layout.
Thermal resistance: the system contributes to energy savings with a high thermal resistance that varies depending on the water content but is not less than 1.35 (m2 * K)/W, with substrate thickness 35 cm and compensation lapillus mixture equal to 15 cm, according to CNR report for the BAS system
Runoff coefficient: specific values can be provided upon request based on studies conducted with the University of Genoa.
