Edmonton Federal Building Living Wall Biofilter
Edmonton, AB, Canada
2,400 sf. Living Wall

Project of the Week Mini Description & Details

Constructed in the late 1950s, the 11-story Edmonton Federal Building is considered one of the city’s most significant modern buildings and one of the best surviving examples of Art Deco design in Canada. In 2014 Nedlaw Living Walls designed and built the multi-award winning living wall for the new Edmonton Federal Building lobby, under the direction of architectural firm Kasian. The Living Wall Biofilter is the focal point of the large glass public atrium – the newly added grand entranceway into the rejuvenated, historic building.

Much more than an aesthetic feature, this living wall biofilter is a working element of the building’s mechanical system, an integral part of its HVAC system. The biofilter draws air through the wall of plants to the growth medium where biological agents consume pollutants. The clean air is returned to the building to improve indoor air quality and building performance.

The living wall and combined water feature provide a calm and serene moment in the busy public space. Installed and maintained by Terra Landscaping, the vibrant layered and organic pattern of the plants makes the wall a work of art, and provides a foil for the otherwise angular and clean-lined space. This multi-level, multi-sided living wall biofilter is the largest biofilter in Alberta, covering 2,400 square feet. A recent study predicts that in the Edmonton region, a biofilter can save $398 – $726 per 100 liters of fresh air generated (by the biofilter).

In addition to providing clean air at a fraction of the cost of a traditional HVAC system, the living wall biofilter at Edmonton Federal contributes to the humidity levels of the atrium space. As such the living wall system is adding innovation points to the LEED Gold certification goal. The Edmonton Federal Building is open year-round to the public. Welcoming employees and guests, the living wall provides a soft, soothing, and secure feeling while entering into the gigantic entrance.

Sam Nunn Atlanta Federal Center
Atlanta, GA, USA
68,000 sf. Greenroofs

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.

Green Acres Farm & Residence
Sonoma, CA, USA
1,581 sf. Greenroof

Project of the Week Mini Description & Details

A 37-acre historic farm site in Sonoma was redeveloped into a Platinum LEED for Homes family residential homestead and organic farm. The two-story home, studio, garage, barn, guest cabin and pool house re-constitute a vernacular farmstead model along sustainable and ecological building practices. Designed as a “green ribbon,” living roofs span the three buildings of the compound, functioning to visually and physically unite the building site into a centralized hub of the farm. Designed and installed by SYMBIOS ecotecture, the living roofs also play a vital role along with straw-bale construction, natural lime plasters, reclaimed lumber, passive and active solar systems, thermal mass (sand-bed) storage, ground loop heat-pumps, and a variety of energy, lighting and water efficient measures to create a model of environmentally sensitive design.

Various greenroof systems were used, including from Colbond (now Bonar) and Optigreen, and the dome-like roof form of the main house required a mechanical slope stabilization system since the upper portion exceeded 35 percent. The vegetative planting plan was developed to provide a high degree of biodiversity for both aesthetic and ecological values. Color, texture and form of the planting palette enriched the overall design of the roofs in conjunction with the architectural facade. Low-growing ground cover species are intermixed with herbaceous species that form a taller canopy layer. Rainwater is harvested from the standing seam metal roofs of the main house and studio. The water is stored in an underground cistern (a former swimming pool) during the winter raining season and is then utilized to irrigate the living roofs, as well as to flush the toilets within the house. The irrigation system is a satellite based weather controller which increases or decreases irrigation water use as determined by the local weather conditions.

Ji Hotel Xiamen Zhongshan Road Pedestrian Street
Xiamen, Fujian, China
2,368 sq. ft. Greenwall

Project of the Week Mini Description & Details

Since 2014, the Huazhu Hotel Group and the Accor Hotels Group have formed a long-term strategic alliance to jointly develop the hotel business in China, including the Ji Hotel Xiamen Zhongshan Road Pedestrian Street, which serves the mid-range market. Opened in 2015, the 5-story hotel has 150 guest rooms perfect for business and leisure travelers. A large verdant green wall from Elmich is a significant aesthetic feature for the hotel’s façade to welcome its guests. Measuring 6 metres (19 feet) in height the distinctive living wall is highly visible from travelers visiting Zhongshan Road, a major tourist spot with many shops and restaurants. In addition to its lush greenery, the green wall will improve the air quality in the area and assist to keep the hotel building cooler in the summer and warmer in the winter.

Project Week Ji Hotel Xiamen Zhongshan Road Pedestrian Street

The Ji Hotel Xiamen Zhongshan Road Pedestrian Street before its greenwall.

The Elmich VersiWall® GM (VGM) modules each contain a geotextile bag filled with a primarily inorganic soil-less lightweight planting media. Pre-planting of the modules 6 to 8 weeks prior to installation in a controlled nursery environment enabled selected green wall plants to be firmly established and oriented vertically. The VGM mounting system is equipped with anti-lift arms and the pilaster mounting rails were bolted directly to the wall to facilitate firm and secure anchorage of the VGM modules to the wall. In September 2016 the green wall was subjected to a wind gust speed of around 170 km/h when Super Typhoon ‘Meranti’ made landfall in Xiamen City, bringing heavy downpours and causing major disruptions to the electricity and water supplies affecting more than 3.2 million homes located in the region. The before and after photos below show how the Ji Hotel Xiamen Zhongshan Road Pedestrian Street’s green wall remained intact despite the battering of Meranti. In this instance, it was a real test of nature to prove the green wall system’s wind uplift resistance.
