Green Roof Technology Reveals Latest Study about Mineral Wool on Living
Green Roof of the Year 2014 – 30 Years and Counting
The second oldest Green Roof Association* in the world, FBB (Fachvereinigung für Bauwerksbegrünung), awarded a prize for Green Roof of the Year 2014 to a 30 year old Green Roof on the Allianz Insurance Company in Stuttgart, Germany. Oldest Green Roof Association DDV (Deutscher Dachgärtner Verband).
The roof is one of the first projects where Jörg Breuning, CEO at Green Roof Service LLC / Green Roof Technology was substantially involved in the realization. Allianz Insurance Company decided in 1981 to build their local headquarters in the heart of Stuttgart. At that time the office building was already a big step forward for urban development in many regards. Along with very advanced, environmentally friendly technologies it was also one of the first buildings to achieve the split between living green working space and luxurious living in downtown of a large City.
The Green Roof is generally assembled around the building and on different levels. Most people in the offices have a view into the green spaces. Some areas of the Green Roof are accessible for coffee breaks and, on the highest floors there is usable garden space for the Condominium owners. The top floor even offers extensive lawn areas as playgrounds for kids.
All Green Roofs together measure over 21,000 sf. This inner city oasis utilized an advanced Optigreen Green Roof Systems with fully automatic high tide and low tide irrigation system in the mineral drainage layer. The plants “decide” when they need irrigation; no drop of water is wasted or can evaporate before reaching a plant. Neither a person nor electricity is needed to operate this fully mechanical system and it leaves enough room for precipitation to fill up the water storage under the plants. This green roof represents a smart combination of Blue Roof and Green Roof as Green Roof Service LLC / Green Roof Technology is still doing it on projects today. It is a foremost and 100% accurate irrigation system far beyond most irrigation systems that are operated by sensors, electricity, Apps, tubes, pipes or other highly vulnerable and expensive equipment we see every day on projects in North America or around the world.
The entire depth of this highly efficient Green Roof technology is approximately 18 inch and has allowed lawn, perennials, shrubs and small trees to grow for over 30 year without replacement or changing out the growing media.
Green Roof Service LLC / Green Roof Technology is proud of this Award and we are pleased to offer more information about it. We offer Green Roof tours for anyone interested in this kind of technology.
This has been a landmark project for more than 3 decades and we congratulate all who are part of this Award!

WASHINGTON, June 18, 2014 -- The final water supply forecast for this year shows the West divided into a wet north and dry south while snowpack has already melted in much of the region, according to data from the USDA National Water and Climate Center (NWCC).
Washington, most of Idaho, Montana, Wyoming and the northern parts of Colorado and Utah are expected to have near normal or above normal water supplies through the rest of summer, according to the forecasts. Far below normal streamflows are expected for the southern parts of Oregon and Utah, southwestern Idaho, California, Arizona, New Mexico and western Nevada.
Many of these areas are in the nearly 500 counties across the country experiencing drought, 57 of them in California alone, according to USDA disaster designations.
This year saw near-record low snowfall in parts of Nevada, California, Arizona, New Mexico and the southern parts of Utah and Oregon. Even with some May precipitation, those areas remain dry. The biggest change this season was in the Washington Cascades. At the beginning of February the snowpack was about half of normal, but it recovered and most of Washington will have a near normal water supply from snowmelt, according to the Center.
Spring snowmelt is well underway, according to NWCC hydrologist Cara McCarthy. “A lot of our SNOTEL sites have already melted out, especially those in the southern half of the West,” McCarthy said.
Colorado had mixed weather during May. “They had winter and summer all in one month: snowmelt, snowfall, snowmelt,” said McCarthy. Heavy precipitation combined with snowmelt, causing flooding in parts of the state.
Forecasters monitor conditions all year, but June is the final forecast of the season. “These are snow-based water supply forecasts,” McCarthy said. “Typically by July there won't be enough snow left on the ground (to measure).”
In Western states where snowmelt accounts for the majority of seasonal water supply, information about snowpack serves as an indicator of future water availability. Streamflow in the West consists largely of accumulated mountain snow that melts and flows into streams as temperatures warm into spring and summer. USDA scientists analyze the snowpack, air temperature, soil moisture and other measurements taken from remote sites to develop the water supply forecasts.
The NWCC water supply forecast is part of several USDA efforts to improve public awareness and mitigate the impacts of climate change, including drought and other extreme weather events. Through the creation of the National Drought Resilience Partnership, launched as part of the President’s Climate Action Plan, federal agencies are working closely with states, tribes and local government to develop a coordinated response to drought.
Since 1939, USDA has conducted snow surveys and issued regular water supply forecasts. View information by state.
In dry years most Therophytes like Asteriscus aquaticus are able to flower as very small plants and produce seeds that are able to survive evon more unfavourable seasons.

Many people wouldn't think twice when gathering a lovely bouquet of flowers while out for a hike. But maybe this is a lesson we should all be practicing and passing down generations, when out enjoying the great outdoors. Transporting flowers for your own benefit is erroneous and punishable in certain situations.
Although the United States doesn't have a specific law protecting wildflowers from being violently up-rooted, the Endangered Species Act of 1973 does cover all of the plants that are slowly vanishing.
Many states have specific laws regarding plants. For example, North Carolina's Plant Protection and Conservation Act states that it is unlawful "to possess any protected plant, or part thereof, which was obtained in violations of this Article or any rule adopted thereunder." If caught, fines can rise as high as $1000.
There are many reasons why you shouldn't pick wildflowers or take plants from the wild. Not only does it reduce the vibrancy of the location, but it also can be damaging to the environment. The USDA explains it perfectly, "We don't often realize it, but wildflowers support entire ecosystems for pollinators, birds, and small animals on a micro scale. Butterflies and other insects, small birds, and animals depend on seeds, nectar, and pollen for their food supply and life support system. In addition, some pollinators are not very mobile or have very small home ranges or depend on just one species of plant and die once their habitat has been destroyed."
In some cases, transporting flowers from the wild can also aid in the spread of invasive species.
It may not be your first reaction when someone goes to pick a few flowers, but just keep in mind that they are a living object as well, attempting to survive and reproduce just like the rest of us. And is it really worth picking these plants, only to have them wilt in a matter of hours or days? Especially when you could be enjoying them all spring and summer if you were to simply let them be.
So my advice to you is, instead of pocketing flowers from Mother Nature's garden, it is just as easy to take a short trip to your local nursery. Not only will there be a great selection on plants to choose from, you will directly be supporting your local community.
Let me reiterate:

Lancaster, like hundreds of other cities across the country, has both a combined sewer system (CSS) and a municipal separate storm sewer system (MS4). While the CSS collects both sewage and stormwater and conveys flows to a wastewater treatment plant, the MS4 collects only stormwater runoff and discharges flow directly to receiving streams.

In 1999 North America discovered that modern green roof technology is more than just an exclusive garden for a few wealthy people on top of a building. Experts understood very quickly that there are unmatched advantages of bringing back nature into locations where it was before.
With this enthusiasm, a lot of environmentalists and environmental organizations started to notice various opportunities to improve, simplify or promote themselves in many ways. Some of these ideas might sound glamorous, but the bigger picture concerning nature, is often disregarded.
In a previous blog post we reported about the ridiculous reductionist research of comparing reflective roofs with green roofs. Today we want to focus on the hype of native plants for green roofs:
Many Americans call a living organism native if these organisms have been on this continent before North America was discovered by European settlers. In their naivety, they have completely forgotten how the Natives have discovered and have lived on the land hundreds to thousands of years before.
So called Native people did the same as any organism; they expanded from their original locations to secure the species. While migrating and expanding over continents, all living organisms will change their environment accordingly. Microorganisms like bacteria or macro organisms like humans follow in the same footprints in evolution. The migration of European settlers did that as well and eventually became 'native'.
For most American people (as mentioned on Wikipedia) the opposite of native is "invasive". This discrimination is completely ignorant to the fact that something must be introduced first before it is invasive, encroaching, or just simply trespassing.
It is even a bigger discrimination and ignorance of God's creation or evolution (whichever you prefer) when these people ( a lot of them call themselves experts) tell us that approximately 1,000 hectares of Bamboo scattered across the USA are a problem for when they call native species. However, at the same time, 1,000,000 hectares (1,000 times more) of genetically modified corn is not a problem. On top of this blatant discrimination, these 'tunnel-view' educated people (including LEED™) are pointing out that roofs are an ideal place for what they deem native plants.
Rooftops might be a stepping stone environment for plants that have been in North America for many thousands of years but when we try and set them up in a new place it is like a conversation of a narrowed down selection of species and disregarding the entire picture. It is obvious that history repeats itself - there are still existing reservations for Native Americans and we all know what effort this was, how discriminating this was and how much diversity, knowledge and inspiration we have lost. We are essentially treating native plants in the same way and that has nothing to do with environmental protection.
These so-called native plants must have a so-called native environment and require all the natural players (other living organisms) to thrive.
* Jeffersonia diphylla for example depends on ants to spread and what building owners want to have colonies of ants?
* The big family of Trifolium (stamped as a weed by nurseries) requires the stiff hair of animals to fulfill their natural calling - how many deer of bears do you want on your roof?
* Or shall we shoot all the birds that spread seeds from introduced trees?
The point of this blog is that any type of nature is better than covering the ground with impervious surface areas like asphalt, concrete of ground mounted solar factories. All our environmental issues are caused by the loss of natural environments. It is also much cheaper to protect these natural environments where they are and avoid relocation into reservations (such as rooftops). Simply by reducing footprints of man-made structures and concentrating human settlements to specific location allows these so-called natives organisms to thrive and to continue their journey of evolution.

Every now and then we find studies comparing green roofs verses white roofs. It seems like and up-stream battle for the green roof industry against the big profits that are being made in the roofing industry with reflective water proofing membranes. All manufacturers of roofing material know that a reflective membrane will sell easier and with a higher profit than a traditional black tar roof. It is cheaper in production, and with the right crew, easier to install as well. In addition, because of the environmental benefit (discovered by LEED), the pricing can be more expensive.
Covering this membrane with a green roof should increase the profits - so we think. In reality, it isn't the case because the lack of horticultural understanding and human's natural fear of nature make it a high risk factor or even a potential lawsuit. Stockholders and risk managers for large roofing manufacturers offer green amenities (because this is good for their image), but never pressure these offers. Unfortunately, for roofing companies, protecting the revenue and profits is of higher priority over the environment and real sustainable practices.
It is no secret that selected manufactures support Universities in order to preform research on reflective membranes verses green roofs. These manufacturers tell the researchers precisely what to say and do so their reputation thrives. Since research jobs are not plenty full and Universities have the same economic pressure as roofing manufacturers, the results of this research may be questionable.
In an older selective or reductionist study at Lawrence Berkeley National Laboratory, the so-called scientist went a step further. Writing a paper, clearly motivated by manufacturers, they described their data as somewhat sparse - does that mean worthless?
We still try to understand the words that are used in this study:
"Somewhat" = to a moderate extent or by a moderate amount
"Sparse" = thinly dispersed or scattered
We at Green Roof Service LLC/Green Roof Technology don't need simplyfied research that says "maybe yes" and "maybe no" in one sentence without considerations of the entire picture. Many people in the green roof industry don't have a scientific backing, but it is a great gift that they have common sense and understand that bringing back nature to where it previously resided is way better than covering the earth under a white burial shroud.
The bear in the stream catching the battling salmon can't extinguish the species - as long as the water is clean. If the water is polluted because of the lack of nature in our built up Cities, there won't be any salmon left and the bear will shortly become extinct as well. Responsible research and researchers can help keep our waterways and neighborhoods clean - or address a topic holisitc.

According a study from prestigious researches at LawrenceBerkeley National Laboratory, One Cyclotron Road, Berkeley, CA 94720, United States and School of Mechanical & Aerospace Engineering, Nanyang Technological University, Singapore, reflective roofs have a higher value for building owners than Green Roofs.
Julian Sproula, Man Pun Wanb, Benjamin H. Mandela and Arthur H. Rosenfeld developed a study that clearly explains the monetary benefits of reflective roofs v.s. Green Roofs v.s. traditional roofs. In their reductionist research, the outcome for green roofs is not good. In a press release they stated:” The researchers acknowledge that their data are somewhat sparse but contend that their analysis is valuable in that it is the first to compare the economic costs and energy savings benefits of all three roof types.” It isn’t the first time – I have seen many worthless studies before…
I am anchored in the Green Roof Industry since 1980, I roll my eyes and shake my head about counterproductive statements and studies like that. In the yellow pages they would have found somebody who could have told them differently and how to spend the generous money from the industry (other than green roof industry) much better – actually in building a Green Roof. Even when building a Green Roof doesn’t help the building owner (according their study) it would have helped the environment.
Bringing back nature into a location where nature was before is simply the best you can do!
My advice: Don’t start covering your Green Roofs or entire nature with a white piece of plastic – just don’t believe every written word on the internet or commercial reductionist research – Use your gut feeling and think out of the box!
