First Steps to Planning a Green Roof

Green Team at Green Roof Technology, - Tuesday, April 23, 2013

 By: Samantha Yurek

Happy Earth Week! Hopefully everyone has taken some time out of their busy lives to lend a hand to our beautiful planet we inhabit. Whether it is picking up some litter, planting a tree or deciding to go all out and look into acquiring a green roof! Here are a few things you should have a good idea of before you leap into the planning process.

1. How sturdy is your roof?  Adding growing media and plants to your rooftop adds weight to your structure. Make sure your roof can handle some extra weight first. Find out the materials and structure of your building.

2. Is your roof sloped?  A slight slope is perfectly fine, but anything steeper than 15 degrees, the roof might become a slide for the plants without additional constructive design.

3. How much are you willing to spend?  Implementing a green roof is an investment for the future. Simple extensive vegetated roofs usually cost around $10-$15 a square foot (pre-grown planter boxes or modular systems are more expensive). Many local programs will help pay for green infrastructure, based on the environmental benefits. 

4. What type of green roof are you looking for?  A simple meadow-like area, not accessible and mainly for the environmental benefits (extensive) or an intensive roof, complete with recreational room and the potential for larger plants such as trees.

5. How are the sunlight conditions?  The majority of green roof plants enjoy direct sunlight to flourish. If the building is situated in a heavily shade area, the green roof plant selection becomes limited.

6. Do you want an integrated solar green roof?  The Sun-Root™ System is the newest of technologies, a fully integrated system and an ideal symbiosis of PV panels and an extensive green roof. It is easy to install and will not penetrate the roof. The entire system has the potential to pay back within 5 years and also meets stormwater requirements in all cities of North America.

 

Do your homework first before deciding on a green roof, our website is a great starting point to increase your green roof knowledge. If you're interested in a green roof or have any questions, please don't hesitate to contact us, we would be happy to help you get started today!

Green Roof Technology has recently partnered with the Anacostia Watershed Society; an organization dedicated to keeping the Anacostia River clean and healthy. Through our partnership we hope to achieve a common goal to increase green spaces and to protect our Anacostia River watershed which runs through our nation's capital and into Maryland. Since 1989, the Anacostia Watershed Society has been the first organization dedicated to protecting the Anacostia River.

ThAnacostia Watershed Society had recently put forth a Green Roof Rebate Program, aimed to encourage residents and building owners to reduce their stormwater runoff on-site and decrease the burden on the District's Combined Sewer Overflow. Available for residential, commercial and institutional properties, this rebate program will reimburse you with $5 per square foot of green space implemented on the property.For most commercial green roofs, that rebate can reduce your overall costs dramatically.

The District Government's Green Roof Rebate Program is administered by the Anacostia Watershed Society and encourages to contact us to see if they are eligible. Feel free to check out the Anacostia Watershed Society homepage here.

Seoul's massive airport is a popular destination for connecting fliers headed to other parts of East Asia from the Americas and Europe. Thanks to its comfortable transit seating areas, expansive duty-free shopping mall and airy main terminal, Incheon earned the highest overall score on the 2012 Skytrax customer satisfaction survey. Incheon also is one of the world's most family-friendly airports. Not only does it have a children's play area, but also childcare lounges and nursing rooms. Older kids might enjoy spending some pent-up energy at the Ice Forest, a large skating rink in the airside terminal.  
 
Other bonuses: This is one of the few airports in the world where you can get free access to a computer and Wi-Fi. Incheon has an impressive seven gardens in the passenger terminal and one in the transportation center. Finally, a free cultural center features exhibits on Korean culture and traditional dance and folk music performances.

Education & Green Roofs - A Learning Experience

The Calhoun School in NYC is a great example of a school utilizing green roof space to form environmental curriculum and promote a hands on learning experience. Back in May of 2005, renovations presented the perfect chance to retro-fit the building with a brand new intensive green roof. The green roof wasn't simply installed for environmental benefits; these renovations created a unique opportunity for outdoor science classrooms and an herb garden in the heart of an urban space. 

Implementing intensive green roofs, extensive green roofs or educational rooftop farms within urban schools would be a great learning tool as well as a benefit to the environment. Besides the obvious positive environmental aspects (stormwater mitigation, insulation, urban heat island relief, etc.) this green space can be used as an outdoor classroom, gardening space or for research.

Incorporating environmental education into an elementary cirriculum is beneficial for two main reasons. Learning to respect the environment at an early age is relatable to environmental ethics later in life. An environmentally friendly routine during childhood makes it more likely that these habits will continue down the road. And spending secondly, spending time outside improves self-esteem, motivation, reading ability and imagination, along with calming capabilities and decreases stress levels.

In the current age of technology, it is easy to spend the majority of your day staring into a glowing screen considering our dependence on computers, smart phones, TVs and e-readers amongst others. Children especially spend a significant amount of time with electronics as companions, inside and outside of school. I may still be in my early twenties, but within the past decade trends have quickly changed; my childhood was spent outside, no internet, no cable, and no smart phones, unlike today. The consequence of a lack of time spent outside has been researched in depth by journalist and author, Richard Louv. He has deemed this phenomenon as Nature Deficit Disorder, and explains the issues associated with a lack of nature in childhood in his book "Last Child in the Woods," published in 2005.

Intensive green roofs can bring a whole new set of opportunities right into the classroom. Hands on experiences, the potential for learning about and growing fresh food, and an on-site outdoor classroom are a few worth mentioning.

Green Roof Industry - learning by (not) doing?

Green Team at Green Roof Technology, - Sunday, March 24, 2013

For eleven years, the green roof industry has been running into the issue of finding a lack of Sedum cuttings between November and May. Green roof plant nurseries are not able to produce Sedum cuttings during this time because they obviously never learned better. During this time they rather grow these plants in pre-vegetated plastic or metal boxes, sitting in a controlled greenhouse for bigger sales in late spring and leaving the clients alone later when exactly these expensive and high carbon foot print containers do not acclimate in their final destination. They call themselves green roof plant experts but hardly understand the typical life cycle of the plants they are growing. 

When average temperatures drop most Sedums (most plants) store their nutrients and energy produced during the growing season in their stems and roots. The best indicator for that is the changing color of the leaves in the fall and when under stress. Once these reserves are stored in the little stems, they are extremely powerful and “programmed” for rooting - not for producing leave mass.  Many Sedums root quicker in winter than in hot summers where they have to deal with high evapotranspiration because of their denser leave mass while their roots are not able to supply them with water to offset the water loss.

Utilizing Sedum cuttings on green roofs can reduce the cost for plants and planting by 90%, assuming the applicators know what they are doing. At the end, the overall costs will drop dramatically which leads into more green roofs and less subsidies from public agencies and non-profit groups. The plant pieces broadcasted in winter are most likely adapted to the conditions in their final location in less than 2-3 months and hardly require watering on hot spring days or in summer. This also reduces maintenance time and costs.   

    

Jörg Breuning: “The lack of common sense and real expertise is the biggest problem in the North American green roof industry.  My person is controversial discussed, many feel intimidated based on my experience and that I address problems directly, which are avoided by other professional or trade associations. I see myself as the stimulus in a literally growing industry.

From an environmental point of view longevity at acceptable costs, low maintenance, no supplemental watering, and the long-term health of the plants are crucial for ongoing success. Customer orientated work requires that we adjusted to nature – nature will never adjust to humans”. 

University of Maryland to Install More Green Roofs

The University of Maryland installed their first extensive green roof back in the fall if 2008 on Cumberland Hall.  Approximately 6,000 square feet of the rooftop is covered in vegetation.  The Adele H. Stamp Union building also completed renovations which involves yet another two new green roofs in 2009.

Summer of 2010 brought a Rooftop Food Garden on top of the South Campus Dining Hall. Planters made from salvaged wooden pallets hold all sorts of food including cucumbers, peppers, potatoes, tomatoes, mint and lavender, to name a few. In addition, the space is available for individual gardening projects and other student research or coursework. In the fall of 2011, the Denton Dining Hall followed suit, when the re-opened building integrated green and cool roof systems.

Although this makes up very few of the many buildings at the University of Maryland, each green roof helps to alleviate storm water runoff, the heat island effect, and each building's heating or cooling costs. 

The University of Maryland's Council on the Environment recently rewarded a grant to two graduate students, to extend on their solar energy and vegetated roof research.  Read the full story by the Diamondback here. 

In the future, it wouldn't be surprising to see more building constructed or renovated complete with green roof systems. The technology is available and the industry has definitely grown in the past few years.

FBB Green Roof Symposium 2013

Green Team at Green Roof Technology, - Wednesday, February 27, 2013

The German FBB (Fachvereinigung Bauwerksbegrunung e.V.) is the oldest Green Roof Association in the world and with around 120 members, probably one of the smallest. However, most FBB members are considered leaders in modern green roof technology and their average green roof experience is far over 20 years. It is an elite group that has seen everything you can imagine related to vegetation on impervious areas.

As the father of all green roof associations, this year's event was again filled with innovations, information and trends.The FBB president, Dr. Gunter Mann, pointed out that there is a huge potential for the industry to increase the annual green roof construction. In 2012, the 120 FBB members reported over 40,000,000 square feet of new construction, a significant addition compared to the previous years. The true annual new green roof construction in Germany might be doubled compared to the rest of the world. However, Germans are modest and not interested in quantity, but specifically in quality. Quality of installation, intelligent research and decent public relations are the foundation of the FBB.

In partnerships with other associations (Landscape Association, Concrete Association, Roofing Association, Association for Water Protection, along with many more) it is impressing to hear about the successful public awareness on green roofs.

The elite group at the FBB does a great, inexpensive and super-efficient job for a better and sustainable environment, mainly throughout Germany and reaching out into the world. For many decades they have been setting milestones for a growing, global industry and it is always a blessing to mingle with the biggest, most experienced and best-educated green roof professionals in the world.

Bravo!

 

Four Questions with Ryan Miller

Green Team at Green Roof Technology, - Monday, February 25, 2013

 

Our very own Ryan Miller was recently interviewed for the Solar Power World Magazine, focusing on our Sun-Root™ System.  Solar Power World is written with a focus upon Technology, Installation and Development, reaching tens of thousands of industry professionals.  “Four Questions with Ryan Miller of Green Roof Technology” will be featured in the upcoming April issue of the Solar Power World Magazine.  The online version can already be previewed on their website, SolarPowerWorldOnline.com!

SPW: What is the concept behind the Sun-Root System?

Miller: As a green-roof company for more than 30 years, we have seen many innovations to modern green roof technology that makes it more marketable and affordable.  When you sit down with clients, they want to know how much they are spending and what is their return.  The payback of a green roof lies somewhere between 15 years to 25 years in most cases, and for many building owners that is not something that excites them.  So we looked for ways to shorten this payback period while still meeting our goal of increasing the world's green spaces.

First International Bird Airport on Intensive Green Roof

Green Team at Green Roof Technology, - Monday, February 18, 2013

 Ornithoport in Bonn

Picture: Bundeskunsthalle

Airports are plentiful in our world, but a unique concept involves creating airports specifically for birds.  An exhibition on the roof of the Art and Exhibition Hall over the summer of 2012, highlights this common area as a destination point for birds.  To aid this bird airport (ornithoport), nesting boxes and feeders were installed, as well as approach and departure structures, complete with flashing airport signals and safety announcements.  All together this presentation is not only an awesome art piece, but probably the best landing facility for birds from all around the world.  The curator of this project, Professor Res Ingold explains, "In our case, it is an artistic project with scientific backing."

Founded in 1992, the Art and Exhibition Hall of the Federal Republic of Germany has played an important role in the community of Bonn, Germany.  Designed by the architect, Gustar Peichl, the building displays various exhibitions in fields of art, archeology, cultural history, science, and technology.  Aside from exhibitions, the community center frequently hosts symposiums, conferences, performances and concerts.  One of the more attractive aspects of the building is the intensive rooftop garden, which is often site for sculpture displays.  This vegetated rooftop is a nice addition for relaxing with a fantastic view of the surrounding city.  In the summer refreshments are served at the beer garden, wildflowers brighten the landscape and the air is busy with buzzing honeybees.  Multiple honey bee colonies call this rooftop garden home.  In 2012 these little magnificent creatures produced 1,200 pounds of honey!  Accurate daily monitoring of the productivity of the honey bees is accessible online in German, French and English.
