Project of the Week Mini Description & Details

The former site of the iconic Rich’s Department Store (Atlanta’s most popular retailer throughout the late 19th and 20th centuries), the present Sam Nunn Atlanta Federal Center serves as the home of several federal agencies, including the GSA and EPA Region 4, and is one of Atlanta’s most environmentally friendly facilities. The center encompasses the six-story Rich’s Building and its beloved clock as the cornerstone of the facade (from 1924), the 10-story Midrise, the eight-story Bridge Building, and the 24-story high-rise Tower. Utilizing American Recovery and Reinvestment Act funds, the $2.6 million project renovation’s goals, consistent with the General Services Administration’s roofing program, were to provide thermal and moisture protection; conserve energy and the environment; reduce utility costs; and help attain energy security by meeting Energy Independence and Security Act requirements.

In testing the roofs’ structural integrity, it was determined that part of the Rich’s portion could not support a vegetated roof; it was changed to a white, 60 mil Tremco “Cool Roof.” But the two Tremco vegetated roofs are highlights of the buildings with planting plans designed by Tremco Roofing’s Mary Ann Uhlmann. Installed by Greenrise Technologies, more than 198,000 colorful sedums, delospermas, native cacti, alliums and more were planted 3 per sf and are set in 4″ of growing media from ItSaul Natural. The combination of roofing systems is meeting the project goals, providing such benefits as a lower installed cost than planned, cutting heating and cooling costs, reducing stormwater runoff by more than 600,000 gallons, and reducing the strain on rooftop HVAC equipment. The collaborative efforts of the National Building Contractors team and the GSA designed a vegetated roof system that not only reduced greenhouse gas emissions but also recycled 80% of the existing roof material including the pavers, waterproofing membrane, and rigid insulation.

Project of the Week Atlanta Botanical Garden Hardin Visitors Center

Project of the Week Description & Details

Comprising 30 acres, the mission of the Atlanta Botanical Garden is to develop and maintain plant collections for display, education, research, conservation and enjoyment, composed of a number of smaller themed indoor and outdoor gardens. Completed in the spring of 2010, the Atlanta Botanical Garden’s Green Expansion Plan was a large-scale expansion project which doubled the size of the Garden while modernizing them at the same time. A number of new facilities constructed include the 600-foot-long Kendeda Canopy Walk providing visitors a journey through the treetops of Storza Woods, the Edible Garden featuring an outdoor kitchen and greenwall with a wide variety of flowering herbs, and the LEED Gold Allen and Gail Hardin Visitors Center. Now facing Piedmont Park, the Visitor Center provides a beautiful new entry experience for visitors and both extensive and intensive greenroofs cover nearly half of its roof area.

EDAW (now AECOM) provided landscape design for the new entrance, LEED Gold SAGE parking deck, and Visitor Center. The Garden Roof Assembly from American Hydrotech was specified, using Stalite PermaTill® growing media. The two inaccessible extensive greenroofs can be seen from the second level balcony, and visitors can walk out onto the intensive greenroof outside which meets grade on the upper level and stroll the paths. Providing additional garden area for visitors and even new wildlife habitat, a wide variety of shrubs, grasses, trees, and perennials were designed to provide color and interest in all seasons, and informational signage pertaining to the greenroofs can be found here as well. Runoff is filtered and an underground 100,000-gallon water cistern harvests stormwater from the seven-acre watershed and provides irrigation for 40% of the new gardens.

SouthfaceEcoOffice1

Project Description & Details

Built by a consortium of construction firms using widely available, off-the-shelf products, materials and technologies, the Southface Eco Office is a three-story structure with a rooftop greenroof. It was officially opened in 2009 after receiving its ENERGY STAR label, as well Platinum LEED certification from the U.S. Green Building Council and EarthCraft Light Commercial certification – a regional green building designation specific to the Southeast. It also meets The 2030 Challenge launched by the non-profit group Architecture 2030. The Eco Office is noted for its average energy cost of less than $25 per day.

Designed by Lord, Aeck & Sargent after an inter-disciplinary design charrette, the Southface Eco Office is an 8,300 square foot environmentally responsible building project showcasing some of the innovative green building technologies available in today’s market. The Turner Foundation Green Roof on top of the third floor expands the office space into a rooftop patio with a spectacular view of downtown Atlanta. It’s home to a custom vegetated roof system using waterproofing from American Hydrotech, drainage from JDR Enterprises, growing media from ItSaul Natural, and a variety of Sedums, Delospermas, Talinums, and Hens and Chicks supplied by Saul Nurseries. It boasts a 6.4 kW photovoltaic array salvaged from a BP gas station, and a 1,750-gallon rainwater collection cistern. For over 30 years, Southface has been the U.S. Southeast’s non-profit leader in the promotion of sustainable homes, workplaces and communities.

Southface hosted the Atlanta Green Roof Symposium on September 15, 2014.
