Cool Roofs Might Increase Air Pollution

Cool Roofs Might Increase Air Pollution

Picture: welt.de

Approximately 35 years ago I learned in horticultural chemistry class how plants utilize the energy of sunlight.  This process is called Photosynthesis and is an everyday example of Photochemistry, a sub-discipline of chemistry or the study of chemical reactions that proceed with the adsorption of light by atoms or molecules.

Other examples of Photochemistry are the degradation of plastics and the formation of Vitamin D with Sunlight.

  Skin aging: caused by 80% of the Sunlight

Over the last half century, it has been well studied that heat and sunlight have a tremendous effect on air quality.  Both, and independent from each other, heat and sunlight can transform the atoms and molecules in the air around us into other chemical combinations that are often harmful for human health.  The same photochemical transfer occurs also with most other particles and substances in the air and increases the chemical cocktail in the air we breathe substantially.

In a recent study of the Cooperative Institute for Research in Environmental Sciences (CIRES) it was confirmed that at night – without the energy of sunlight – nitrate radicals naturally help cleanse the atmosphere.  Acting as a “janitor” of the night sky, the nitrate radical scrubs away air pollutants such as volatile organic compounds that would otherwise form smog and ozone.  The cleansing compound only works nightshifts, however, since sunlight destroys the light-sensitive molecule.  The study suspects that the street lights in cities reduce this cleansing effect.

It doesn’t take much to understand that Cool Roofs or Reflective Roofs multiply the light energy in the air, reducing not only light-sensitive molecules but also converting most other atoms, molecules and particles in the air into potentially more harmful chemical combinations.

This can be proven by many simple observations:

  • Photovoltaic (PV) elements increase their output with higher light intensity because of the energy in the light (more photons from sunlight increase the electromagnetic interaction).
  • The human skin reacts on intense sunlight with a photochemical reaction (often ending in skin cancer).
  • Sunlight changes the composition of most natural of man-made materials – typically degradation.
  • Plants change their appearance when exposed to excessive light – often they die.
  • Plants “suffocate” when exposed to sunlight 24/7.

Sunburn on plant leaf.

Nowadays numerous studies (typically sponsored my manufacturers) focus only on the surface temperature making everybody believe that cool roof, or so called reflective roofs, are environmentally friendly because of the lower surface temperature.  Isn't it worth to look at the bigger picture of what happens when reflecting sunlight off of roof tops – i.e. polluting the air with additional sunlight?  I am not suspecting that they were paid to ignore this dramatic effect but it shows to me that the responsibility of researchers is in some cases is questionable.  My countryman Albert Einstein would have said: “Insanity: doing the same thing over and over again and expecting different results.”

"Cool Roofs" or  "Fool Roofs"?

Installation of reflective roofs requires additional protection for workers.

Meet Jorg Breuning at ASLA 2013 Annual Expo

Green Team at Green Roof Technology, - Wednesday, November 06, 2013

American Society of Landscape Architects is holding their annual meeting and expo this year in Boston from November 15th until the 18th.  

On Monday, Nov. 18th at 8:00 am, Jorg Breuning and Rob Tilson will hold an education session titled "Solar Panels and Green Roofs Fully Integrated - The Smart Future Development." 

The collaborative presentation between Green Roof Technology and Tilson Group will showcase two of the leaders in the green roof industry pushing the boundaries of their field.  

The benefits of combining green roofs with solar panels is well documented.  The two technologies have been used together for many years, beginning in Germany nearly 30 years ago when both technologies were only first being developed.

Over the decades both technologies have advanced greatly.  Today, fully integrated green roofs with solar panel systems, known as Solar Garden Roofs, have been developed that maximize the two technology's beneficial synergistic effects.  

The Learning Objectives of Jorg and Rob's discussion are as followed:

1) Learn about an integrated technology that combines renewable energy with vegetated roofs, multiplies benefits and significantly reduces cost.
2) Understand the key elements and flow chart evaluation of whether this technology fits a project.
3) Acquire extensive product knowledge including weight, size, potential power output, maintenance, and warranties.
4) Compose proper specifications for construction and define the intersection of the different tasks with lessons learned from past project successes. 

You can take a sneak peak at Jorg's presentation by downloading a pdf on our Resources page -- available here.


Unterm Regenturm: Under the Raintower

Green Team at Green Roof Technology, - Wednesday, October 16, 2013

In 1992 Jörg Breuning, Green Roof Service LLC and Thomas Heuman, Heuman Gartenanlagen provided consulting services to Hundertwasser's architects, Springmann and Associates. It was quite an effort the contemporary artist and the City of Plochingen to develop an entire block of the city's historical district. This city has been around since the year 1146. 

From the outside the historical buildings still remain the same and all facing to an intensive greenroof courtyard in the back. This courtyard and the backside of the buildings received an artists' distinguished signature in 1993. Efficient and gorgeous, the entire courtyard resides on a two story parking garage and grocery store, meanwhile the lush green environment above creates a different feeling. Hundreds of various plants decorate the landscape with paving materials snaking their way through to make perfect paths. The sloped roofs facing the courtyard are also fully or partially greened. Approximately fifty green roofs occupy the colorful, wavy historical buildings.

This particular construction of modern green roof technology underlines the artist's inspirations as well as supports diverse vegetation. The structure is a magnet to tourists and a true landmark of the region for over twenty years and well worth a visit!

Cradle to Cradle Concept on a Green Roof

Green Team at Green Roof Technology, - Wednesday, September 25, 2013

"The world will not evolve past its current state of crisis by using
the same thinking that created the situation"  - Albert Einstein

 

The Cradle to Cradle theory reappeared in 2002 with the release of Cradle to Cradle: Remaking the Way We Make Things by William McDonough and Michael Braungart. A concept dedicated to mimicking nature in which products can be fully recycled. Instead of materials having a specified lifespan, they can indefinitely be transformed into other products. A design created to enrich and benefit the environment even as products are manufactured and used.

Recently, the cradle to cradle design has been proposed for a green roof project in the United Kingdom. By-products from the London Sustainable Industries Park will be collected and transformed into aggregate material used for drainage purposes on green roofs and walkways.

Green Roof Technology has many opportunities to use recycled materials in our projects - as long as the green roof's efficiency isn't compromised or becomes the neighborhood landfill.

New Instant Green Roofs

Joe’s Paint Releases: New Instant Green Roofs

Our favorite environmental expert and green roof research specialist Joe is up to his old tricks.  Joe hit the PR circuit again this week releasing a full range of new roof greening products. 

Not satisfied with only offering a green roof in a can, Joe is now offering a full line of instant green roofs.  His new products include a highly reflective white paint for roofs and façades. The can comes with a pair of sun glasses and two cartons of greasy sunscreen (SPF 90) for an entire neighborhood.   

The best green roof and green wall product is already successful on the markets: An artificial grass mat that can be rolled out.  Joe has the fake grass in multiple colors to create Blue Roofs, Brown Roofs and Red Roofs. The good thing is, that after a season you can also fill-up the landfills with toxic waste and contributing your part to a healthy growth of the economy.

 Grass Test

Joe is very excited about the new product line and promises: “Next year we come up with an entire line of fake honeybees, polyethylene spiders and colorful plastic butterflies with remote control. Just before Christmas we will also see artificial flowers and Christmas trees (comes with a fake turkey). “

 

 

 All fake grass products are tested under real conditions. 

If you want to walk on grass without having a green roof we recommend the grass Flip-Flops. Retaining almost 100% sweat and you can’t run-off.

 

We all love Joe here Green Roof Technology because he is constantly pushing the green roof industry and green technologies to new heights.

Revisiting an Award Winning Green Roof

Green Team at Green Roof Technology, - Friday, August 30, 2013


Green Roof Technology has had the pleasure of working with Royal Caribbean to design and implement natural grass lawns on five of their flagship Celebrity Cruises vessels.  Each Solstice Class ship is equipped with over 20,000 sf of lush fairway quality grass.  We are thrilled to be able to say that our green roofs have sailed around the world countless times.  

This past week Jorg was asked to check in on one ship that is currently sailing about the Mediterranean Sea.  A minor disruption had occurred in the  irrigation system and needed to be attended to.  Armed with myriad senors and software updates, Jorg jetted off to Rome to meet up with the ship in port.  Jorg returns next week and we will update you with a complete report of his excursion. 

Have a great weekend! 

Therapeutic Properties of Green Roofs

Green Team at Green Roof Technology, - Monday, August 19, 2013

By: Samantha Yurek


Situated on the 8th floor, this green roof is within view of
many of the hospital's rooms at Mercy Medical Center in Baltimore.

Flowering plants are a common sight spotting in any hospital wing, mainly attached with get well soon tags. The new trend seems to be green that will last more than a week or two. Many hospitals and health wellness buildings are incorporating green space, much of it making an appearance on the rooftops. Staring at an attractive green landscape rather than an unappealing tar-stained rooftop has the potential to make every patient calmer and happier on a daily basis. It has been proven that views of natural landscapes have a positive effect on the emotional and mental health of those being treated, as well as those visiting.

The Baltimore Sun recently published an article in their healing section titled, Garden Rx: Hospitals and homeowners alike are investing in the therapeutic properties of landscaped places. The article highlights the addition of healing gardens in well-known hospitals in Baltimore such as Mercy Medical Center, Baltimore Washington Medical Center, Kennedy Krieger Institute, Johns Hopkins Hospital and the UMD Rehabilitation and Orthopedic Institute.

Many of these healing gardens are designed to give patients, family and employees green space to relax and learn and heal within. The addition of green roof space provides many hospital rooms with preferred views of green plant life instead of a bland, brick building. Mercy Medical Center incorporated both healing gardens within a green roof, utilizing their space for both environmental and social benefits.

But not all patients can experience the benefits of an outdoor garden consequence of a compromised immune system. Months spent in the hospital battling leukemia created a unique opportunity for one SUNY-ESF landscape architecture student, Kevan Busa. Determined to graduate on time, but confined within the walls of a hospital, Kevan completed his final project on the healing potential of landscape design from a patient's perspective. Highlighted in the June 2013 issue of Landscape Architecture Magazine, Kevan explains the frustration of a poorly designed healing space. A visit to an outdoor garden is out of the question for many patients. Busa wrote, "the solution may be gardens that can be experienced from indoors, through glass. This idea may not sound terribly inviting, but it is a far preferable alternative to 100 days of brick walls."

Green roof space that can be viewed from individual hospital rooms could be the solution to a quicker healing time and happier patients.

A well-known hospital in Germany, Diakonie-Klinikum Stuttgart, has approximately 150,000 square feet of green roof along with indoor plants as large as trees. The greening of this hospital has been an ongoing process since 1990.

Visiting 1st Solar Garden Roof

Green Team at Green Roof Technology, - Wednesday, August 14, 2013

A vast experimental roof top garden is located on the New York City Department of Parks and Recreation Building on Randall’s Island.  A few years ago the department opened its roof top up to companies to display their latest innovations in green roofing.  Over the years several dozen technologies have been installed, making the roof top home to hundreds of kinds of plants.  From lightweight extensive green roofs, to vegetable farms, to solar garden roofs, all kinds of green roofs are open for public tours.

During the early spring of 2012 we had the pleasure of installing four of our Sun-Root™ Modules on the roof, making the department’s building home to the first Solar Garden Roof System in the United States.  Super Storm Sandy made landfall only 6 months after installation and the system was successfully wind tested with maximum sustained winds at 85 mph with some gusts reaching 92 mph. 

Jörg recently visited the roof top and came back with some beautiful pictures we wish to share with you all. The system is engineered to support healthy plant growth under the PV panels - unique and brilliant! Ask us for details and investment options.
