LEED Credits for Green Roofs

Chantier-termin2

 

How can Green Roofs, and more specially Hydropack LEED to multiple benefits? Green roofs afford a wide variety of cost-saving and environmental benefits. There are six major categories under the LEED rating systems and Hydropack Green Roof Systems can help you achieve credits under 5 of them with a potential of 41 credits total!

Sustainable sites (Potential credit of 6 out of 14 points)

SS Credit 5.1 & 5.2: Protect or restore habitat and maximize open space: (2 points)
The Green Roof may include native or adapted plants, provide habitat, and promote biodiversity. This design requires minimal or no irrigation and low maintenance.

SS Credit 6.1 & 6.2: Storm water design (quantity & quality): (2 points)
Hydropack reduces storm water runoff by more than 60% depending on the previous rain events (rate and quantity). Hydropack may also be considered as storm water treatment through its ability to remove suspended solids and other pollutants. The USGBC specifies that green roofs can meet this objective when the installation covers at least 50% of the roof surface.

SS Credit 7.1 & 7.2: Heat island e­ffect (2 points)
Hydropack can reduce roof temperatures from summertime highs of up to 170°F to less than 90°F, especially in cities. The USGBC specifies green roofs as a way to meet this objective so long as the green roof covers at least 50% of the roof surface.

Water Efficiency (Potential credit of 4 points)

WE Credit 1.1: Water efficiency landscaping reduced by 50% (2 points)

WE 1.2: Water efficient landscaping, no potable use or no irrigation (4 points)
When this credit is pursued, the design may not include permanent irrigation. Hydropack is often designed so that irrigation is not required as we select drought-resistant plants.

Materials and resources (Potential of 6 out of 11 points)

MR Credit 2.2: Construction waste management (2 points)

MR Credit 4.1 & 4.2: Recycled content (2 points)
Hydropack is made of 100% recycled HDPE and the compost contained in the growth media are both pre-consumer and post-consumer materials. Contributes towards 10% to 20% of the total value of the project materials originating from recycled material (measured by weight x cost).

MR Credit 5.1 & 5.2: Regional materials (2 points)
More than half of the North American population is within a 500-mile radius of Hydropack's production (Vegetal i.D. nursery). 10% to 20% may be manufactured and assembled within 500 miles.

Energy and Atmosphere (Potential up to 19 points)

EA Credit 1.1 to EA 1.19
After establishing the minimum level of energy efficiency for the proposed building, demonstrate a percentage improvement that the green roof can help you with. Because of its heat absorption properties, Hydropack has been shown to reduce energy demand by more than 30% annually in certain types of structures, geography and configurations. Reduced demand and increased efficiency may also lead to smaller cooling systems and lower capital costs.
Optimal Solution: Any Hydropack option.

Innovation and Design Process (Potential credit of 5 points)

Green roofs may qualify for innovation and design credits by improving the workplace environment, creating an educational laboratory, or a recreational space.

Optimal Solution overall to pursue the highest LEED credit score:

Hydropack® with Native Plants
Hydropack® Standard plant mix

Leadership in Energy and Environmental Design (LEED®) has been developed by the United States Green Building Council (USGBC). It provides standards for certifying buildings constructed with the intent of implementing greater environmental performance, efficiency and occupant health.
