New Orleans Botanical Gardens Green Wall – VGM Living Wall
Earlier this week, Tournesol Siteworks was invited by Warren Gorowitz, Vice President of Sustainability at Ewing Irrigation and Landscape Supply, to participate in a “TweetChat” that was, more specifically, a “#landscapechat.” Anyone in the Twitter world may participate in TweetChats, by adding a hashtag (#) and the specific topic – this was a landscape chat focused on green walls and green roofs. The #landscapechat is hosted each week by Corona Tools (who was unavailable, so Warren hosted our chat) and happens weekly on Wednesdays, featuring different topics during the year.

Prior to the event, we collaborated with Warren on a list of questions and answers. During the hour, Warren tweeted (asked us) specific questions, which we answered and attached a few photos to illustrate. He asked about our company, and about us being a premier solution provider of landscape elements for rooftops, terraces, streetscapes, etc…nationwide. The chat moved to ask some of the trends we see in green walls, which are a boom in amenity space development and large urban public space projects.

Warren asked a bit about the importance of green walls and some of the challenges. Challenges include the maintenance, access, and understanding the effects of weather (wind, light, heat, etc…) on the plants. There are also different types of green walls, including tray-based and modular systems, trellis-based and interior systems, all at different price points. For green roofs, there are shallow extensive systems, deeper intensive roofs, tray-based or built-in-place systems.

The chat/discussion turned to how green walls/roofs promote sustainability in urban spaces, such as how they promote a healthy environment – plants provide oxygen and pleasant surroundings, and renew and restore the ecosystem. Green roofs filter and moderate stormwater flows, reducing stress on existing drain water systems. Hospitals use green walls to promote healing and peaceful environments for patients. Both green roofs and walls mitigate urban heat island effect, as well.
Meanwhile, others in the #landscapechat community were also tweeting questions about plants, moisture of soil, whether or not coffee would grow in a green wall (yes, it can) and even the use of media block.

The #landscapechat ended with questions about the future of green roofs and walls; we see a wave toward proliferation and integration into everyday commercial construction. We’re also seeing a move with green roofs towards integrating amenity spaces – making them more usable. It was the first TweetChat that Tournesol Siteworks has been part of, and it was a great experience. We look forward to participating in another one in the future.
