Inaugural Green Wall Industry Survey Report from Green Roofs for Healthy Cities by Kara Orr

October 13, 2016 at 3:21 pm

Over 600,000 square feet of green walls were installed across North America in 2015.

Green Roofs for Healthy Cities (GRHC) is pleased to announce the results of the first-ever annual Green Wall Industry Survey.  In 2015, more than 600,000 square feet of green walls were installed across North America.

The annual Green Wall Industry Survey collected a variety of data on North American green wall installations, including size, location, wall structure, type of green wall system, and whether or not the installation qualified for LEED credits.  The report is available, at no cost, at

“We are very pleased with the leadership in the green wall industry which has enabled us to compile this market research. As the sector continues to grow we look forward to even better data in the years to come,” said Steven W. Peck, Founder and President, Green Roofs for Healthy Cities. “We look forward to learning the latest in green wall research and technology at CitiesAlive: 14th Annual Green Roof and Wall Conference in Washington, DC from November 1-4, 2016.”

Green wall installations are taking place in almost every US state, with some preference for the coastal states.  California is leading in green wall installations, with New York and Florida following in second and third place respectively.  A major selling point of green wall installations is their eligibility for USGBC LEED credits for a project.  Additionally, financial, social and environmental benefits such as improved property value, health and well-being, and reduced energy use can be attributed to green wall installations.

Video & Project of the Week for April 20, 2015: SOLARIS, Fusionopolis (Phase 2B)

April 21, 2015 at 4:14 pm Project of the Week: 4/20/15


Fusionopolis (Phase 2B), One North
32,152 sf Greenroofs
3,272 sf Atrium Planter Boxes
44,293 sf Green Ramp
1,765 sf Greenwalls


Project Description & Details

SOLARIS is a 15 story office building located in the Fusionopolis hub in central Singapore’s One-North Business Park, an area dedicated to research and development in technology, media, physical sciences & engineering industries. Since the site was originally a military base, most of the original ecological system had been destroyed. Designed by T. R. Hamzah & Yeang, the architect’s response was to conserve what little greenery there was by building on areas which would cause the least ecological damage, helping to improve the site’s biodiversity simply through the positioning of the building.

SOLARIS is comprised of two towers connected with a passively-ventilated central atrium. Office floors are linked by a series of sky terraces which span the atrium at upper floors. The architect designed over 8,000 square meters landscaping, a total more than the area of building. The “eco-building” replaced the original site with a ratio of 108% of landscape to site area. The “green ramp” at SOLARIS is a 1.5 kilometer linear, continuous landscape ramp that was built to connect the ground level to the upper levels of the building, linking the basement Eco-cell with a cascading sequence of roof-gardens at the highest levels. The building has accomplished a 36% reduction in overall energy consumption by integrating fully landscaped areas directly into the facade of the building. A dramatic vision of the possibilities inherent in Skyrise greenery design, 95% of the project’s total landscaped area is above ground level.

Find more photos and additional information about this project in The International Greenroof & Greenwall Projects Database.


SOLARIS is’s Project of the Week 4/20/15 Replay in honor of its designer, the green architect, ecologist and planner Ken Yeang who is the Opening Keynote for the Greenroofs & Walls of the World Virtual Summit 2015. Enjoy his lively hour-long interview by Linda Velazquez for an in-depth look into Ken’s signature bioclimatic eco-architecture plus much more insight into SOLARIS itself, now playing though May 31, 2015.
