Greenroof Project of the Week for June 24, 2013: City of Minneapolis Target Center Arena

June 28, 2013 at 1:48 pm

City of Minneapolis Target Center Arena
Minneapolis, MN, USA
113,000 sf. Greenroof

Project Description & Details

The 20,500-seat Target Center is home of the NBA’s Timberwolves, concerts and other events, and when the Target Center Arena needed a new roof, the City of Minneapolis chose to model a sustainable building and stormwater management approach by re-roofing with a green roof, the first installed on an arena in North America. Approximately 1 million gallons of stormwater are captured annually by the 2.5 acre green roof, preventing drainage into the Mississippi River.

Designed by Leo A. Daly and Kestrel Design Group, the pattern of the pavers that divide the growing zones reveal a design based on veins of a leaf from afar. The Target Center green roof consists of a state-of-the-art waterproofing membrane from Sika Sarnafil, Bonar (formerly Colbond) Enkadrain, a 2.75 inch deep growing zone in the center of the main arena roof structure and a deeper 3.5-inch growing zone around the perimeter where the structural capacity is greater to maximize the rooflite® Extensive MCL growing medium. A pre-grown Sempergreen sedum mat was supplemented with native plugs and seed to enhance plant diversity and ecological resilience and to reflect the mix of flora found in the dolomite bluffs overlooking the Mississippi and Minnesota rivers – while a few have failed, about 30 species flourish on the roof.

Project Description & Details

Located in San Juan’s Botanical Gardens, the mission of the International Institute of Tropical Forestry (IITF) is to develop and disseminate scientifically-based knowledge that contributes to the conservation of forests, wildlife, and watersheds of the American Tropics. Updating and restoring its headquarters complex, the new design will reduce the actual environmental footprint with a modern storm water management system that incorporates green roofs, grass parking, rainwater harvesting and retention ponds.

Architect Jeannette Rullan from RMA Architects, greenroof consultant David L. Aponte from PRGD, and USDA engineer Juan Vissepo designed the three green roofs as an experimental intervention that would further the understanding in hydrological, thermal and ecological behavior/benefits in a sub-tropical scenario. ZinCo‘s green roof material and rooflite extensive growing media was installed on all three green roofs. A total of 22 species where used – around 16,000 plugs were installed on the project.

Greenroof & Greenwall Project of the Week for January 21, 2013: Cuartel de Ballajá (Ballajá Infantry Barracks Building)

January 24, 2013 at 10:00 pm

Greenroofs.com  Project of the Week: 1/21/13

Cuartel de Ballajá
(Ballajá Infantry Barracks Building)
San Juan, Puerto Rico, USA
24,000 sf. Greenroof & 480 sf. Greenwall

Project Description & Details

El  Cuartel de Ballaja (The Ballaja Infantry Barracks Building) was constructed by the Spanish army between 1854 and 1864. The structure is one of the most impressive constructed by Spain in the New World and it stands as the last example of monumental military architecture by the Spanish Monarchy in the Americas.

Designed by ECo Architecture + Landscape + Engineering, WTI Inc, and David Aponte of PR Green Design, materials included 2″ of rooflite drain w/ drain channels, filter fabric, 4″ average of rooflite growing medium and 60,000 plants that vary from plugs to 6″ pots. An 1,800 sf artificial wetland was built on the living roof as stormwater management and to cool down the roof. When the roof reaches critical drought conditions, the irrigation system takes water from the wetland and uses it for irrigation of both the greenroof and 480 sf living wall. The wall serves as a biofilter for the “lake,” which is stocked with fish. The Cuartel de Ballajá also sports a 151.2 KW PV system with 720 solar panels.

The Cuartel de Ballajá is featured in the month of February in the 2013 Greenroofs & Walls of the World™ Calendar.
