plant walls for vibrant green spaces

By Preston Koerner | May 12, 2010 | topics: IAQ, Landscape, Modern design

The folks at Plant Solutions installed this vibrant living wall in a conference room of their Scottsdale office. The TerraScreen Living Wall is made with two 4’x4′ panels, which are made with a black, powder-coated, galvanized steel wire, and brackets that attach to the wall. The panels protrude a little less than five inches from the wall.

Plants are placed in 6″ no-hole cachepots and an irrigation system keeps them watered. This installation has pothos plants with colorful Neoregelia Medusa variety, according to Living Wall Art.

Green walls, like other interior plants, not only bring a slice of nature to the unnatural, but they also capture airborne pollution through absorption or by sticking to the plants. They can be good for indoor air quality.

Living walls are popular these days, especially with a NY Times article on the topic by Kristina Shevory, “Gardens that Grow on Walls.” It should be clear, though, they require care and a plan with respect to irrigation, lighting, nutrition, and plant choice. Some living walls die, while other green walls thrive.

WESST Corporation Gets LEED Credit for Use of Indoor Plants

WESST CORPORATION GETS LEED CREDIT FOR USE OF INDOOR PLANTS

Albuquerque New Mexico’s Wesst Corporation was recently awarded Silver LEED Certification in part through the use of indoor plants, only the second project to do so in the U.S.

Credit for the use of live plants indoors was given under LEED (Leadership in Energy and Environmental Design), a third party rating system offered through the U.S. Green Building Council (USGBC). Points were awarded in the category of Innovation in Design, under LEED.

According to Studio Southwest Architects and the LEED Consultant Halcom Consulting, key points cited in the submittal were live plant’s ability to filter VOC’s (Volatile Organic Compounds), uptake carbon dioxide during photosynthesis, and release fresh oxygen into the atmosphere. The Plant type and percentage of the installation along with VOC removal characteristics with milligram per hour removal properties for formaldehyde, Xylene and ammonia were cited within the LEED submittal. Green Plants For Green Buildings (GPGB.Org) extensive library of resources back up the research and findings in the submittal. The 420 Sq Ft bio-filtration wall measures 17 ft by 24 feet high and was installed by NedLaw of Canada. The “Bio” wall is fully integrated into the buildings air handling system.

The credit award supports the argument that human beings need to feel connected to the natural environment in order to enjoy a sense of psychological, physical and social well-being.  Biophilia directly confronts the issue of aesthetics and our evolved sense of beauty. The patterns, forms, textures and colors of nature provide abundant models that can be used in building and product design to enhance their aesthetic appeal, not just their functionality and efficiency. Incorporating this natural sense of beauty into a building makes them not only greener in the environmental sense, but also greener in a human sense.

Unlike Australia’s ‘Green Star’ green building rating system, the current USGBC LEED system does not yet offer a specified direct credit for the inclusion of live plant applications. Within the current LEED section titled “Innovation in Design” it is possible for plants to be part of a specially developed use.

It is widely recognized that plants in the workplace offer more than just aesthetic value.  In fact, research science and studies have shown that in addition to improving indoor air quality they help reduce stress, enhance employee attitudes, and increase productivity.

First Building in U.S. to Get LEED Credit for Use of Indoor Plants

E & E Awarded the Platinum LEED Certification

By Joe Zazzera, LEED AP, GRP | March 22, 2010 | topics: press release, LEED credit, use of indoor plants The Ecology and Environment (E & E) Headquarters in Lancaster, New York was recently awarded Platinum LEED Certification in part through the use of indoor plants. Credit for the use of live plants indoors was given under LEED (Leadership in Energy and Environmental Design), a third party rating system offered through the US Green Building Council (USGBC). Points were awarded in the category of Innovation in Operation and Maintenance, under LEED for Existing Buildings 2.0. The specific credit was for the Biophilic Connection to plant life found in this building, which supports the argument that human beings need to feel connected to the natural environment in order to enjoy a sense of psychological, physical and social well being.  Biophilia directly confronts the issue of aesthetics and our evolved sense of beauty.

Benefits of Living Plants In Buildings

awareness of the need and desire for indoor air quality

By: Joe Zazzera, LEED AP, GRP |  February 1, 2010 | topics: LEED, Indoor Plant Benefits, Environmental Awareness With the advent of the LEED rating system and with LEED for homes coming on in a strong way, the awareness of the need and desire for indoor air quality improvement and control is greater than ever. Due to our increased environmental awareness, we no longer trust the health and quality of our food, clothing, hair-care products, cleaning products, carpeting and paint.  Plenty of data exists proving the toxicity of these items.  We can no longer ignorantly keep these chemicals near us in any form without risking becoming irritated and sick behind their use. When it comes to our living and working environments, we want the best and healthiest options we can afford. According to the ASID Study “The impact of interior design and the bottom line”, and The American Journal of Medicine, businesses pay $15 Billion a year in direct medical costs due to problems related to poor indoor air quality. Over 900 VOC’S (volatile organic compounds) can be present in indoor environmental air.  Not all VOC’S are harmful but the harsh ones like formaldehyde, xylene, benzene, chloroform, ammonia, acetone are commonly used in items like paint, carpeting, construction supplies, glues, ceiling tiles, furniture and finishes. This poor indoor air quality has negative effects on our health.  Out-gassing, or emissions of these VOC’S, cause problems such as nausea, headache, coughs, fatigue, dry skin and sore throats. These are just some of the results of poor indoor air quality.

How Living Indoor Plants Help

Live Indoor Plants convert harmful VOC’S into carbon-based materials that they then use in the photosynthesis process to make their own food. The resulting byproduct is oxygen. This is actually a bimimicry action; there is no other known way to convert these compounds into something harmless. It is as nature designed and intended.   Air filter devices and HVAC systems can capture some of these VOC’s but they are still there, they haven’t changed.  Plants do what our most complicated HVAC systems can’t, and plants offer a host of other physical, emotional, and mental benefits. Scientists have found that there is a microcosm, an ecosystem of sorts that exists in a regular soil mix consisting of plant roots and ordinary harmless bacteria.  The bacteria breaks down the VOC’s and the plant roots nourish and keep the bacteria alive.  Plants absorb the newly converted compounds and use them in the photosynthesis process for food and energy and growth. In a two-year study by Norwegian Professor Tove Fjeld, in 51 offices with living indoor plants, fatigue was reduced by 20%, headaches and sore throats by 30%, coughs by a whopping 40% and dry skin irritations by 25%. In yet another study by Texas A&M Professor Dr. Roger Ulrich, it was proven that when plants are present in hospitals, patients are ready to go home after surgery in less time; they require less pain medication; and nurses report that they are less likely to become upset or despondent from their illness or surgery. Ulrich’s study also showed that plants improved problem solving skills, ideation and creative performance. So research definitely shows that plants improve health!

How Many Plants

Research by NASA as well as Australian Scientist Margaret Burchett have shown that 1 plant per 100-160 square feet of indoor space is sufficient to have an effect and improve indoor air quality. They found that the plant size did not matter as long as they were of the 8” nursery pot size or larger.  The studies have shown that upon initial installation, VOC’S were removed within 4-5 days; any added VOC’s (by addition of furniture etc.) are removed within 24 hours. This shows that plants get better at processing VOC’S.

What are the Costs

There have been many return on investment studies that show anywhere from 30% to 300% ROI. The typical return in the office environment shows 12% improvement in productivity along with 60% reduction in absenteeism rates. This translates to a $24 ROI per day per employee commercially for a cost of about $200 per year per employee for plants including maintenance. The residential environment is difficult to chart due to the fact that there is very little data and not much consistency with which to make accurate measurements. Designs simply vary too much to give accurate ROI numbers.  Experience has shown that most residential clients are not as concerned about specific dollar ROI as they are their interior environmental quality and aesthetics. It is discernible however, that the benefits outweigh the costs.

The Biophilic Connection

When most of us want to relax and unwind, we go for a walk in nature, take our dogs to the park or go camping or fishing. This Biophilic need for plants, life and nature is an archetypical one that is innate in all of us. In her work Building Biophilia: Connecting People to Nature in Building Design, Environmental Psychologist, Judith Heerwagen, PhD states,  “Studies show that incorporating the natural environment into buildings can have a positive influence on psychological, physical and social well being”.  She goes on to state; “Appreciating natural beauty isn’t something that some people have and others don’t. It doesn’t need advanced education and training. It happens without effort or even conscience awareness. The more our buildings can tap into our ancient sense of beauty, the more likely they will support us psychologically and emotionally, as well as functionally”. Our job as designers, contractors and builders is to educate and reconnect our clients to this need by providing them with the highest quality of design, décor and environmental quality as we can. Now more than ever the health benefit, productivity improvements and the return on investment for the biophilic connection to nature should be part of that design.

Impressions of Greenbuild 2009

By: Joe Zazzera, LEED AP, GRP |  November 17, 2009 | topics: GreenBuild

Its 5 am on the Saturday morning following GreenBuild 2009. For the last 6 days I have been fully immersed in the GreenBuild experience.  Next to me sits 3 (one for each of the expo days) stacks of follow-up business cards that require some sort of action or follow-up. Our company provided plant material and deliveries for 4 different booths for the event all of which are members of Green Plants For Green Buildings. Since we were the local company, material for their booths was shipped into our facility where it was stored prior to delivery.  We had a target installation of 6 am Sunday morning, two days before the opening of the EXPO. 1100 vendors and booths, I have never seen such a conference event. On the downstairs level, I am told that some of the booths cost in the hundreds of thousands of dollars to construct. Incredible.

Our booth came with 75 free expo passes, all of which had to be assigned electronically. I worked hard through marketing efforts to make sure that all passes got assigned and used. Many were assigned and used by civic leaders, university decision makers, construction project managers, non-profit trustees and the like. I knew that if I could get them assigned, I could have 75 new impressions for GPGB. The best part was that their badges when printed said “Green Plants For Green Buildings” along the bottom.

The last number I heard on attendance was just under 28,000 actual attendance. Many times during the expo there were people shoulder to shoulder.  For the expo, I brought in 2 additional people for the booth to discuss GPGB, our mission and distribute literature. Often, each of us was talking to someone different at the same time. The crowd was full of decision makers and people who are steering sustainability goals for their companies and designs. Many were from Government, EPA, researchers, scientists, architects, designers, builders and list goes on

Having attended many of the conference presentations. The common theme seemed to be focused on the Biophilic nature of green building and the further incorporation of it into building design. LEED has spent many years on numbers and science to prove out energy and water savings but a lot less on the human component integration.  This, I believe is changing.

I have never been more excited about the potential of our industry, I believe that our role and industry will change and plants and planted systems will become more integrated into the building system and have a more specific function in addition to the aesthetics.

Plants WILL become a part of the LEED rating system; I had several conversations with employees of the USGBC including their creative director, who state their support for plants and what we do. In fact the new USBGC offices (designed and installed buy Ambius), had originally specified a living plant wall within their new DC office space but was put on hold due to budgetary reasons, sad it has not been built yet but great that we are in their radar.

The first day of the conference I played the Authentically green PowerPoint  (edited for GreenBuild). We had 2 people say that they had received credit points for plants under the ID section of LEED. I am following up on the research of the scorecards and verifying the point awards but if this is so, it removes one more obstacle on our quest. The second day I did away with the PowerPoint (people generally didn’t read it anyway) and on the screen simply put “LEED AP’s- Have you received credit points for plants under ID in LEED? – Please let us know” The prior day had been so fruitful talking to the LEED AP’s that It became obvious that was who we needed to talk to, I decided, if there were more we needed to know so we can make a database.  I am following up on all of these and will report what I find but it looks encouraging so far. During the expo, I only had one objection and question about mold.

Based on my experience at GreenBuild, I am very hopeful for our industry, I believe the growth will be explosive in the future and will lead to additional competition.  Since we are established players, we will be in excellent positions to adapt and grow.

Innovation in Design-Leed ID

requirements of an Innovation In Design or ID credit and how it might apply to interior plants

By: Joe Zazzera, LEED AP, GRP |  May 14, 2009 | topics: LEED, Innovation in Design Credit, Green Building Rating System The intent of an Innovation in Design credit is to provide the opportunity to achieve exceptional performance above the requirements set by the LEED rating system and/or innovative performance in categories not specifically addressed by the LEED Green Building Rating System. The basic requirements can be achieved through several paths or a combination of those paths.  The Innovation in Design path requires you to achieve significant measurable environmental performance using a strategy not addressed in the LEED rating system. A submittal under this path must include the intent, the requirements for compliance, the submittals to demonstrate compliance and the approach or strategy. A second path would be exemplary performance, which would essentially be for doubling the credit point requirements or achieving the next incremental percentage threshold for and existing credit in LEED. This path would not be available for indoor plants since plants are not currently in the rating system. To my knowledge, there has never been a credit award for indoor plants in any category of the USGBC LEED rating system. I know of two Canadian projects that have received awards in the ID category, both for green biofiltration walls. It is our hope to find a project that is willing to submit for an ID credit under LEED, as a means of getting indoor plants into the rating system. As part of that submittal, we believe an educational component, about the benefits of live indoor plants would be well received and go a long way towards LEED acceptance. To all of you involved at the local or national level, keep your eye out for a project that might be a good candidate for submittal under ID.  It will require an owner that believes in what we do and is wiling to not only pay the submittal fees under LEED but risk not getting the award even after submittal. If we can get just one submittal through the system, I believe it will set a precedent and open the door for other building owners to act.  Once it becomes common knowledge of the availability of live indoor plants within the LEED rating system, there will be yet one more benefit for owners to use indoor plants on their projects.

Green Plants for Green Buildings forms LEED Advocacy Committee

By: Joe Zazzera, LEED AP, GRP |  May 1, 2009 | topics: LEED Advocacy, Supporter from GPGB

In May of 2009 the LEED Advocacy Committee of Green Plants For Green Buildings was formed. The single mission of this committee is to get live indoor plants into the LEED rating system either through an addition in the Indoor Environmental (IEQ) category, Innovation in Design (ID) category or both. Since live indoor plants are in other rating systems, we believe the lack of indoor plants in LEED was simply an oversight.

On our committee are 9 people, all from the interior plantscape industry including 3 GPGB board members. 5 of our committee members are LEED Accredited Professionals.

One of the first orders of business of our Committee was to research and review the possibility of an Interior Plantscape Certification program. The USGBC does not create their own certification programs; they only adopt existing certifications such as Green Seal, Green Label etc, into the LEED rating system. The Committee, after review, made the decision not to have GPGB create a certification program. The Board and the Committee believe it is important that any program be a 3rd party program and not created by us. Instead, it was determined that the best course of action was to support but not formally endorse the Green Earth, Green Plants certification program. By doing this, we could never come under scrutiny or threaten our non-profit status.

In July, the USGBC released a “Call for Ideas” to members and the public at large. The purpose of a call for ideas is for the USGBC to hear what is important and relevant from the public and from industry. The USGBC uses such information to steer changes and improvements to the rating system. GPGB immediately put out a call for action industry wide. Requests showed up not only to GPGB members but also in and around the entire plant world including PLANET, PIA and FNGLA. There is no way that we know of to get a reporting as to the number of submittals were entered but we believe based on those we have talked to that it was substantial. We know we are being heard. The USGBC is consensus based and loves grass roots measures. The Technical Advisory Groups (TAG’s) are responsible for the review of the scientific and supporting data for submissions. Since we know we have lots of supporting scientific information, we believe we will be heard.

Earlier this year, the USGBC announced its desire to work on some standards with the UK’s BREAM system and Australia’s Green Star system (equivalent LEED rating systems). What this says, we believe, is that there is respect by the USGBC for those rating systems. Since the Green Star system already has adopted live indoor plants into their system, our hope is that LEED will follow suit. Additionally, a few months back, New Zealand began a pilot program using live indoor plants in their rating system.

Our new website will have a link for known LEED certified buildings that are using live indoor plants in their buildings. Even the USGBC’s offices in Washington, DC, uses live plants.

We are putting out a call for projects to the industry. What we would like to see is a building owner who has not yet submitted their LEED paperwork, to make a commitment to submit under the ID, Innovation In Design, category. Innovation in Design is just that, a specialty credit for creative ways of effecting change using technology, education or some other form. Since this can only be utilized on a building that has not done their submittals, we are asking our membership to talk to their architects and owners about upcoming projects. The LEED AP’s on our committee have offered their services or consultations to help that process. In the absence of an actual credit category for indoor plants, the ID category might be the next best path and possibly a quicker one.

We are working on some LEED for home discussions but nothing has come out of pursuing that yet. We have been told that unlike commercial projects, which have to be completed prior to full LEED submittal, with LEED for homes a concept can be submitted for approval prior to the project. We are trying to verify this now as there are many changes with LEED for homes at the moment.

Green Plants for Green Buildings will have a booth at Greenbuild this year in Phoenix. Our booth will be on the second level of the pavilion near the food area. Several members of our committee are coming into Phoenix at their own expense to attend and man the GPGB booth. Please let us know if any of you are attending, we could always use the help at the booth.

Finally, we know what we need is a “white paper” for submission to the USGBC. We have asked our members to become members of their local USGBC chapters and to spread the indoor plant message but we also need to submit our request to the USGBC to be heard on an official basis. Our plan is to develop this white paper and to have it vetted out by some of our industry leaders as well as other industry leaders. By doing this we will be submitting the best possible document and request.

I will continue to make updates when needed.

Thank you for supporting GPGB and our mission.

Indoor Environmental Quality and LEED

indoor plants and indoor environmental quality (IEQ)

By: Joe Zazzera, LEED AP, GRP |  March 31, 2010 | topics: US Green Building Council’s LEED Rating System Under the US Green Building Council’s LEED rating system there is a credit category for Indoor Environmental Quality or IEQ. Within the system a building owner can submit to receive credit points for using materials that are low VOC,  (volatile organic compound) emitting adhesives, sealants, paints, coatings, carpet systems, composite woods, laminate adhesives and furniture. In addition to several prerequisites, there are credits available for air monitoring and delivery, having construction management plans to deal with and filter air during construction and prior to occupancy, as well as chemical source controls.  The general idea is to avoid sick building problems before they arise by using products that are low or no VOC emitting and have monitoring and control devices in place during and after construction. This category deals specifically with increased occupant comfort, well-being and productivity. Let me repeat that…well-being, comfort and productivity! Nearly every credit within this category references those three words in its intent, yet despite the research, findings and science proving the benefits of indoor plants on the human experience, the increase in productivity and removal of toxins and VOC’s, there is no credit category for plants indoors. The Green Building Council of Australia has an equivalent building rating system known as “Green Star”.  In their system they aim to encourage and recognize the installation of indoor plants that improve environmental quality. Points are awarded when plants are included in the office build out or tenant improvement. The criteria for compliance must have the following:
  • Plant species selected on suitability to indoors
  • Two-year horticultural maintenance plan
  • Minimum density of one 300mm (12”) plant or two 200mm (8”) plants per two work settings
  • Additional points can be added for increased plant density (double density=double points)
Beyond the criteria there are also compliance requirement submittals and documentation, which I encourage you to review (Green Star- Office interiors v1.1 IEQ-15 Indoor Plants) This past month there was some good news published by press release from the USGBC.  Australia’s Green Star, the UK’s BREEAM rating system and USGBC’s LEED system have agreed to work together to develop metrics and alignment tools to create consistency in measuring and reporting. Although this in and of itself may not seem like a very big deal, in my opinion it is huge because it indicates mutual respect between these three entities and gets them working together toward a common goal. I believe this cohesive approach will eventually give live plants their correct place within the LEED rating system, but only if we push for the change. I encourage Interiorscapers everywhere to learn as much as you can about the Green Star requirements and talk about it with your current and potential clients. Additionally, join your local USGBC chapter and talk to anyone there who will listen about the system and why indoor plants should be in the LEED rating system. It is these kinds of grass roots effort that will get us recognized and get green plants in green buildings.
