Greenroofs.com Project of the Week: October 2, 2017

Mini Description & Details

Hedgegate is an award-winning private residence in Sea Ranch, located west of California Highway 1 on California’s scenic north Sonoma coast. The site and structures are regulated to preserve the view of the Pacific Ocean.

The limited 1300 sf of conditioned space and the 16-ft. height above the coastal meadow enable Hedgegate to sit lightly on the land, featuring dual living roofs and a green wall. The HOA provisions strictly limit approved species not only to California natives, but to a limited list of species specific to the local flora of the coastal meadow and coastal terrace ecological systems.

Owner architect Janet MacKinnon of AE Design used her modular sodpodmod system for propagation and delivery of local native species within a 5-inch growing media depth from rooflite and Enkadrain drainage from BonarBuilt. Each window of the main upper level of Hedgegate looks over the lower green roof, and the lower roof provides space for edible plants outside the kitchen.

The rainwater and stormwater from the roof, retaining wall, rain room, and driveway is collected in this drought-prone location in two 2,000 gallon underground cisterns for drip irrigation of the living roofs. Graywater is collected for irrigation of the ground landscaping.

The low water demand of the 3-inch depth of the green wall, made from Sedum Mat from Sempergreen plus additional natives and exotics, is met using a closed loop, drip irrigation system, recirculating water from the Koi pond at the base of the green wall.

As a prototype, Hedgegate exemplifies how water systems can be integrated into a net zero home. The owners gladly open their home that, to date, has been toured by over 300 local visitors (including architects and builders).

Annually, thousands of travelers on California Highway 1 plus hikers and bikers on the parallel trails on each side of the highway experience the beautiful Hedgegate green roofs in the foreground of their view of the Pacific Ocean and the California Coastal National Monument.

Project of the Week Mini Description & Details

Situated in San Francisco’s Golden Gate Park, the world’s first and largest double LEED Platinum museum, the California Academy of Sciences boasts exhibition space, education, conservation and research beneath one large greenroof. The CAS was designed by Renzo Piano Building Workshop along with a slew of other professionals. A single building beneath the new 2.5-acre living roof houses Academy components that once stretched across 12 structures including the Morrison Planetarium, Kimball Natural History Museum and Steinhart Aquarium.

Rana Creek Living Architecture worked with Renzo Piano Building Workshop, Chong and Partners Architecture, SWA Group, ARUP, and the Academy to design the living roof with seven dramatic hills and four steeply sloped domes, replicating the surrounding rolling hills. Dotted with circular skylights fitted with heat sensors, the skylights can open to further cool the building when needed.

Greenroofs.com Project Week June 2017 California Academy Sciences Living Roof

The undulating living roof sits 35 feet in the air and is planted with over 50 native wildflowers and other species. An open-air observation terrace enables visitors to get a close-up look at the roof’s lush canopy of plants. With slopes up to 60 degrees, a biodegradable modular system was developed (later purchased by Tremco), and 50,000 biodegradable modular BioTrays™ were planted. The Garden Roof® Assembly, Ultimate Assembly®, and waterproofing were supplied by American Hydrotech. Surrounded by 60,000 photovoltaic cells, up to 10% of energy needs are supplied and it prevents the release of more than 405,000 pounds of greenhouse gas emissions annually. The BioTrays keep interior temperatures about 10° F cooler, reduce low frequency noise by 40 dB, decrease the ambient Urban Heat Island effect being 40° cooler, and absorb about 98% of stormwater, preventing up to 3.6 million gallons of runoff per year. A masterpiece of sustainable architecture, blending seamlessly into its setting while employing a wide variety of innovative features and operations to minimize its footprint, the California Academy of Sciences and its Living Roof is the “greenest museum in the world.”

Publisher’s Note: The California Academy of Sciences is a featured project at the 2017 Greenroofs & Walls of the World™ Virtual Summit, highlighted in “The Design of Green Roofs in the Urban Public Realm” video by John L. Wong, FASLA, FAAR, SWA Managing Principal and Chairman and “Top 10 Green Infrastructure Eco-Agents in a Climate-Changing World” video by Linda Velazquez.

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.

Golden 1 Center
Sacramento, CA, USA
4,800 sq. ft. Greenwalls (7)

Project of the Week Mini Description & Details

As the world’s first indoor sports venue certified LEED Platinum, the Golden 1 Center is the brand new home of the NBA’s Sacramento Kings, featuring seven sections of LiveWall® green walls. Designed by AECOM to be different from a typical sports arena unconnected from its surroundings and lifeless except on game days, the Golden 1 Center celebrates Sacramento’s climate and lifestyle. Its innovative indoor-outdoor design re-imagines how an arena can relate to the streetscapes and neighborhoods around it. Reflecting the region and connecting to the city, the living walls are a prominent feature of Golden 1 Center.

Project of the Week Golden 1 Center LiveWall

Project of the Week Golden 1 Center LiveWall

The inspired idea was to make the building look as if it rests on the green walls, rooting the arena in the landscape and extending it from the new plaza up to the walls of the arena itself. The design redefines how an arena’s footprint affects its environment and community and the green walls were a natural outgrowth of the King’s commitment to sustainability. As visitors walk into the arena, they see living bands of green that change with different sections displaying different plants based on the varying patterns of sun and shade around the building. Completed in September 2016, the seven sections of the Golden 1 Center green wall vary in dimensions and total 4,800 square feet and include 2,700 LiveWall modular planters in a custom platinum color. With a slope of about 10 degrees, they feature 18 different types of plants and 5,400 plants in total, watered with LiveWall Outdoor – Automatic Irrigation. All flowering plants bloom in shades of purple, the Kings’ signature color. Publicly accessible, the green walls are visible from multiple vantage points around the arena. Whether installed indoors or outdoors, green walls are visually appealing and inviting, inspiring and healthful, and beneficial to the environment, and the green walls at the Golden 1 Center in Sacramento enliven the exterior of the world’s greenest indoor sports and entertainment arena.
