Green Roof on Floating Home "Siberfisch"

Green Team at Green Roof Technology, - Monday, January 21, 2013

First Sustainable Home on the Water with a Green Roof

 

With the cost of living in large cities constantly rising, the search for viable alternatives is constant.

Flo Florian and Sascha Akkermann of design firm Confused-Direction and the project-developer Bernhard Urich had urban affordability in mind when they designed the Silberfisch houseboat.

The house is a thoroughly modern floating home that, instead of occupying a valuable plot of land, is anchored in a body of water. In theory, the Silberfisch would allow residents to remain in a location indefinitely or relocate on a whim. It’s an interesting concept whose acceptance by the general public might be debatable.

However, the eco-friendly principles underlying the house are universally appealing. Two of the primary “green” methods used in the house’s construction are a green roof planted with vegetation and the use of reclaimed wood wherever possible. The toilet is an Eco-Toilet which saves water recources. Additionally, the house produces zero emissions. As home prices and eco-friendliness become increasingly critical issues, Confused-Direction’s Silberfisch houseboat may become a realistic option.

 

 

 

 

 

 

 

 

 

Silberfisch houseboat is a floating home by Bernhard Urich and the guys from the design firm Confused-Direction Flo Florian and Sascha Akkermann. This eco-friendly project, with zero emissions, represents a balanced mix of design and maritime romance. It has been designed for the areas with big water surfaces or in cities where property costs are high house boats offer an alternative.

Un Jardin sur le Toit – First Green Roof Fragrance

by Jorg Breuning

Jardin sur le Toit by Hermès features a little slice of nature perched on the rooftop of the building of the house of Hermès in Paris, France. A feast for the sense and the mind. A fragrance of light and delight, crunchy and cheerful.

 

Hermes launches the new fourth fragrance from the collection of garden-inspired fragrances Un Jardin, named Un Jardin Sur Le Toit or “A Garden on the Roof” in 2011. Un Jardin Sur Le Toit refers to the especially luxurious garden located on the Hermes’ headquarters building roof. A secret roof garden, hidden in the heart of the city, in Paris.

The garden is full of aromatic herbs, flowers and fruits whose flavors vary as they pass through the metamorphosis induced by the seasons. Its fresh and sweet-smelling atmosphere is captured by apple, pear, rose, green grass, basil, magnolia and compost notes.  This fruity, vegetal, floral eau de toilette is appreciated by both women and men.

The composition is designed by Jean-Claude Ellena.

Long before green roofs became necessity and rooftop farming was trendy in North America, Dipl.-Ing Markus Wittling was planning to elevate an entire vineyard on top of the Wine Museum in Cologne, Germany.  Build in 2002, the sloped green roof spans over the entire museum building of almost 20,000 square feet. It is the first vineyard on a roof, the first sloped rooftop farm and the first and oldest organic urban farm on a roof in the world.

In the middle ages Cologne was the most important wine trading town north of the Alps.  The "Weinmuseum Köln e.V." is honoring this factwith a brand new museum with astonishing and educational exhibits on wine. The green roof displays 40 of the most important grape species from around the world situated onto 720 vine stocks.  The soil layer (growing media) including granular drainage is approximately 27 inches deep and consists of a blend of porous volcano material like Lava rock and Pumice - materials in which grapes simply grow best. 

 This rooftop vineyard is a prime example of the performance of modern green roof technology and is ideal for educational purposes.  If you have a chance to visit Cologne, the Wine Museum is a must on your Green Roof Safari and your effort will be rewarded with amazing wine tasting

Sun-Root System unfazed by Superstorm Sandy

Green Team at Green Roof Technology, - Tuesday, December 04, 2012

by Ryan Miller

In April of 2012, Green Roof Technology introduced the first Sun-Root solar green roof system to the United States when we installed a 1 kW system (4 Sun-Root Modules) atop the New York Parks & Rec. office on Randall’s Island in New York City. The rooftop, which is eye-level with commuters on the Triboro bridge, creates and stores enough power during the day to power a series of rooftop LED lights throughout the night.  New York City Parks & Rec was drawn to this technology as a means of adding solar power without the need to drill into the membrane to harness the solar array.

Although controlled wind studies have already proven the strength of this system, we are now able to report some real-life wind tests.  Recent Superstorm Sandy made landfall late October, only 6 months after installation, and left without moving the Sun-Root System an inch.  New York City reported maximum sustained winds at 85 mph with some gusts reaching 92 mph .  Upon visiting the site a week after the storm made landfall we found that our original placements of the Sun-Root withstood the winds without a shift.   Jorg could not be happier.


Swarthmore College's Little White Grub Problem

Green Team at Green Roof Technology, - Friday, October 26, 2012
A few months ago we were contacted by Swarthmore College to help identify the cause of a disturbance on the roof.  During a routine visit in August about 20% of a large, upper section of a green roof was completely torn up.  The disturbance occurred in areas where low-growing Sedums, such as S. sexangulare, S. album, and S. spurium dominate.  Areas where taller Sedums, such as S. takesimense, S. kamtschaticum grow were left undisturbed.  

Further investigation located the likely perpetrators.  Numerous white grubs were found in soil.  The likely cause of the Sedums being torn up is from birds scavenging for a snack.  The grubs feed off the roots of the Sedums, weakening their ability to resist the damage caused by the birds.  

Our article about the damage inflicted on the green roof and ways to remediate the problem continues in our Autumn 2012 issue of Green Instance.  The Scott Arboretum of Swarthmore College has also written a summary of the events, which can be seen here.

The Enclave

The Enclave Gets a Lawn

Last week Green Roof Technology, with the help from some friends from Highview Creations, spent  3 days installing a 4300 sf. sod lawn at The Enclave in College Park, Maryland.  The project was a huge success.  Every step of the way went nearly as smoothly as we had imagined.  

Here's a succession of photos taken over the course of the install.  Enjoy!

Just a note to everyone out there:  Rolling out 4300 sf of sod in 100 degree heat is HARD work.  I spent most of the day soaking myself down under the sprinklers.   

Most Economic Green Walls

 Paris Green Wall

 

Some decades ago Patrick Blanc, French botanist working at the French National Centre for Scientific Research and specialized in plants from tropical forests created and introduced a unique design for a vertical garden with real plants (Vertical Garden, Green Wall or Mur Végétal). His simple system or other much more sophisticated systems are based on a consistent water and nutrient supply comparable to horizontal high tide/ low tide (Ebbe/Flut) systems in super-efficient nurseries. These systems often include artificial light and heat/cooling for sustainable growth.

Without being a horticultural expert Patrick Blanc was able to start a new trend utilizing horizontal plant propagating systems applied to the vertical as living art. Maintenance and operational costs of all these wall planted systems are very high and so the environmental benefit is certainly questionable. Typically in less than 10 years costs for maintenance and replanting increase the cost for installation without considering the high consumption of energy and water. 

Today when you fly in to Paris Airport Charles de Gaulle you will see multiple, small green walls - very attractive, lush green with an appealing biodiversity. Closer investigations discovered that these walls the next step of green walls that are super-efficient and extremely low cost for installation and maintenance. The systems at Charles de Gaulle Airport in Paris don’t need any artificial lights, they are completely disconnected from any power and water source and they are very efficient dust collectors. The amazing biodiversity has potential for the highest LEED rating.

Here are a few plants identified:

  • Attractiva plasticifolia (grown out of recycled content)
  • Fakefolia polychloridenses (PCB senct)
  • Metatrashus recyclisa (never green invasive)
  • Ripoffera myclientus `Variegatus´ (native)
  • Hidensia polyestertonia (forever green)

 

Good art reinvented.

Episcopal Academy Green Roof Check-up

Green Team at Green Roof Technology, - Monday, August 20, 2012

By Andrew Yanders

Last Friday I drove up to Newtown Square, PA to check-up on two green roofs we installed earlier this summer at the Episcopal Academy.  I was joined by two of our Philly friends from Urban Ecoforms, Zach and Jared.  

July was a remarkable month.  The extreme heat coupled with the lack of precipitation made the first days of establishment especially stressful.  We placed the roofs on a strict regime of water - beginning with the first week and gradually reducing the amount of water week by week until irrigation ceased after 4 weeks.  

As expected, many of the plants did exceptionally well.  Notably, Delosperma cooperi and Allium schoenoprasum had no problem handling the conditions.  Our Sedum cuttings did not fare so well.  The surface of the growing media dried too quickly and became too hot for roots to adequately form.

This hot area on the roof where the cuttings did not establish well was planted with a couple of trays of Sedum sexangulare and Sedum reflexum and a five gallon buckets worth of assorted Sedum cuttings was again spread.  The weather has cooled significantly in August and we feel the Sedum cuttings should establish nicely this time.

Planting a green roof is not a precise science.  Trial and error is the only way to find out if a species is going to work or not in a specific location.  We are finding out on the Academy roof that shading is creating two distinct zones on the small 700 sf roof.  The temperature and exposure difference between the two zones is dramatically impacting the growing habits of the plants on the roof.  

Station Mall Going Green

Green Team at Green Roof Technology, - Thursday, July 26, 2012

by Andrew Yanders

Along the banks of the St. Laurence River in Sault Ste. Marie, ON sits the Station Mall.  The expansive 42 acre plot dominates the town's waterfront.  When viewed from above the entire property is an island of asphalt and rubber roofing.  This impervious area creates an incredible 28 million gallons of stormwater runoff each year, equivalent to 42 Olympic swimming pools.  Last month Jorg and Andrew traveled to Ontario to meet with an executive team from the Mall and discuss ways to improve the environmental performance the property.  Green Roof Technology is proud to report they have signed a contract with the Station Mall to create a 'Greening Master Plan' for the Station Mall.  Designs are under way, so stayed tuned for updates, but in the mean time enjoy some photos of our most recent trip to beautiful Sault Ste. Marie.

A new boardwalk provides pedestrians an enjoyable passage from the town center to the historical Sault Ste. Marie Canal and beyond to the Whitefish Island natural preserve.  

A brief stop at the Baltimore Convention Center Roof Garden

Green Team at Green Roof Technology, - Wednesday, July 25, 2012

by Ryan Miller

This past Friday I traveled into the heart of Baltimore City to visit the roof garden atop the Convention Center.  On the second floor huge floor to ceiling windows frame the roof garden and encourage visitors to take a step out into nature.  With benches and tables scattered throughout the garden, you can tell the owner's intent was to bring people outside, not only to look onto the city surrounding them, but to sit down and enjoy the unique natural environment.

The roof garden was completed in 2010.  Initially, the Convention Center was only going to receive a new waterproof membrane, but the roofing company, Barrett Company, suggested the owners go above and beyond the traditional upgrade and take part of a growing trend, bringing nature back to our urban areas.  I for one am glad the Convention Center owner had the foresight and courage to install a roof garden and did not succumb to the hesitance many property owners do when deciding to go with green roofs.  

Throughout the hundreds of Black Eyed Susan’s in the garden you will see numerous bees flying about.  No need to worry though, they have too big of a playground to concern themselves with visitors.

During my visit, the national Firemans & EMT convention brought in thousands of visitors to the Convention Center.  Many of them took time to eat their lunch and relax in this oasis just two stories up from busy Pratt steet, which you could almost hear none of. 

As I visit other cities I’m jealous of the green spaces they have for people to just relax and take in nature.  I’m glad I visited this roof garden as I now have a place to show off to visitors and colleagues alike.

I plan on adding this roof to our tour of Baltimore City green roofs on September 13th.  Please email me if you are interested in attending this tour, Ryan@hvccb.com.
