The Hellenic Treasury – Constitution Square
Athens, Greece
6,997 sf. Greenroof

Project of the Week Mini Description & Details

Considered the most important square of modern Athens from both a historical and social point of view, Syntagma (Constitution) Square is at the epicentre of commercial activity and Greek politics, situated opposite the Greek Parliament. The Greek Ministry of Finance installed a lightweight green roof, or oikostegi, within a shallow substrate depth (less than 10 cm) on the Treasury in Constitution Square with the main motivation being to provide a research roof to study the thermodynamic impact of a green roof in hot Athens. Designed and installed by Oikosteges, or OS Green Roofs, mainly indigenous Hellenic aromatic herbs were selected to be able to survive the harsh conditions such as several species of thyme, sage, lavender, mint, and oregano, among others.

Studies of the thermodynamics of the roof in September 2008 concluded that the thermal performance of the building was significantly affected by the installation. In further studies in August 2009, energy savings of 50% were observed for air conditioning in the floor directly below the installation. Energy savings totaling €5,630 per annum were recorded, which translates to a 9% saving in air conditioning and a 4% saving in heating bills for the whole building.

The study also stated that while measurements were being made by thermal cameras, a plethora of birds and beneficial insects were observed on the roof, ranging from robin redbreasts, yellow hammers, yellow tits, coal tits, and sparrows to kestrels hovering high above eyeing up the smaller birds. Also, many species of pollinators have been seen such as honey bees, tiger swallowtail and monarch butterflies – plus dragonflies and ladybugs. The study suggested that both the micro-climate and biodiversity of Constitution Square had been improved by the oikostegi.

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.

Greenroofs.com Project Week Edmonton Federal Building Living Wall Biofilter

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.

Greenroofs.com Project Week Sam Nunn Atlanta Federal Center

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.

Greenroofs.com Project Week Green Acres Farm Residence Symbios eco-tecture

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.
