Green Roofs in Singapore

Green Team at Green Roof Technology, - Monday, December 23, 2013

By: Samantha Yurek

In Southeast Asia. one island-city is rising above the rest. Singapore has been working on a greening blueprint of the city since 1992. Their ultimate goal: to evolve into a city within a garden! With approximately 272 square miles and 4.6 million people, the biggest challenge faced is space.

 

With 148 acres of vegetated roof space, Singapore has already made it a priority to promote green space. Careful planning has helped to conserve 9% of their total land mass to parks and nature reserves. In 1986, only 36% of Singapore was green space, compared to almost 47% known today.

 

The Parkroyal Hotel, opened earlier this year, is covered in green roofs and walls. Totaling 15,000 square meters of green space all together.

The School of Art, Design and Media at the NanYang Technological University in Singapore sports a curving green roof, giving the building a sleek look. As buildings continue to green, Singapore will grow closer to their goal of becoming a garden with a city nestled inside rather than a city with a few gardens.

Many companies have been involved with the green in of Singapore. To name one, Verditecture LTD, has been in the building and construction industries since 2003. A partner of Optigreen, they have been focusing most of their time on skyrise greenery. 

Solar Garden Roof Study

Solar Garden Roof Study and ROI

An extensive study about the fully integrated Photovoltaic and Green Roof solution is finally available in English. Green Roof Service LLC / Green Roof Technology performed excellent work that demonstrates all the features of a Solar Garden Roof and Sun-RootTM module.

Successful implemented on European projects over more than 5 years, the Solar Garden Roof can now catch-up in North America. “I am often wondering, why the American market is hesitating in regards of living green innovation,” says Jörg Breuning, "the savings or payback potential of green living technologies is in the US so much higher than in any other country of the world."

It is estimated that Washington, DC alone has a potential of over 2 Million square feet of green roofs combined with PV in the next 24 month. This could reduce the stromwater run-off by over 25 Million Gallons per year and produce over 26 Megawatt hours of electricity in only 12 month. Most of these smart rooftop solutions would actually payback in less than 5 years.

A bare roof with exposed water proofing has no payback.

Interested developer, architects and planners are welcome to visit two demonstrations projects – one in New York, Randal’s Island and another one in the DC area at Prospect Solar.

The system will be also presented at Cities Alive in San Francisco next week.

Highlighting Baltimore Green Roofs!

Green Team at Green Roof Technology, - Monday, September 09, 2013

By: Samantha Yurek

With a growing number of green roofs appearing, the city of Baltimore is slowly climbing up the green ladder. I wanted to take some time to highlight a few green roofs located right in our neighborhood. In a dense urban setting, green roofs can play a huge role in sustainability efforts because of their ability to mitigate storm water during large rain events. Urban watersheds are especially vulnerable to environmental issues consequence of a high density of people mixed with large amounts of impervious surface area.

 

 1. Baltimore's National Aquarium


Created to aid the aquarium's conservation efforts, the extensive green roof atop the National Aquarium in Baltimore stretched for 4,000 square feet. Built in 2005 by the Furbish Company, the flourishing roof has been a pleasant addition to the inner harbor.

2.  Hilton Hotel


The largest of them all, at 32,000 square feet would be located on the Hilton Hotel, installed by the Furbish Company in 2008. Adjacent to the Baltimore Convention Center and Camden Yards, the hotel has 757 rooms available. The green roofs reside on both the east and west wings of the building and create additional outdoor green space for citizens to enjoy.

3. Baltimore Convention Center


The Baltimore Convention Center followed in 2010, with the Barrett Company working to install a 15,000 square foot green roof. Doubling as a recreational area, this roof has been transformed into a green oasis in the heart of an urban space.

4. Mary Catherine Bunting Center at Mercy Medical Center


Also in 2010, Mercy Medical Center stepped up and installed three green rooftops to assist with patient health. With 17,500 square feet, these intensive green roofs are also viewed from many of the patient's windows. This project was completed with the help of Mahan Rykiel Associates.

An increase in green space in Baltimore is a fantastic step toward a more sustainable city. Keep up the good work Baltimore!

 

 

Herbicides in Green Roof Runoff Polluting Drinking Water

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

The issue of root penetration is known to most in the green roofing industry.  The relatively complex world of roofing membrane compounds and organic chemistry has resulted in most green roof professionals defaulting to local instructional manuals, which default to FLL testing records.  But just because a material is effective does not mean it is not harmful, e.g. lead in paint.

In 1997, Bayer Aktiengesellschaft was the assignee of Patent US 5672568 A titled “Root growth inhibitors for building materials comprising monohydric alcohol esters of mecoprop.”   Root-resistant bitumen mixtures were soon marketed.

This past week the Berlin Senate’s Department for Urban Development and Environment and the Berlin State Office for Health and Social Affair published a series of recommendations for the prevention of environmental pollution due to the release of the herbicide Mecoprop from root-resistant bitumen membrane sheets. 

The statement reads:

Investigations at the Swiss Federal Institute for Water Resource and Conservation (EAWAG) on behalf of the Swiss Federal Office for the Environment (FOEN) have shown that Mecoprop under natural weather exposure is released from the bitumen sheets and the precipitate is washed out.

Rain water contaminated with Mecoprop can pollute combined sewers or surface waters.  Due to the low rate of elimination in sewage treatment plants results in a particularly high risk potential.  In a decentralized rainwater infiltration system there is a risk of soil and groundwater contamination.   (Translated from the German)

The report goes on to make simple recommendations.  The first says the use of bituminous membranes impregnated with Mecoprop should not be used unless absolutely necessary for structural reasons.  Second, they should never be used in protected water areas.

Since the issuance of Patent US 5672568 A, there has been a series of scientific papers published reporting the leaching of biocides from bitumen waterproofing.  They can be found here, here and here

Green Roof Technology is against any use of herbicides in green roof construction or maintenance.  For more information on how to protect your building against root penetration without the use of poisonous herbicides please contact our office.  

Episcopal Academy Installs More Green Roofs

Green Team at Green Roof Technology, - Wednesday, July 10, 2013

On July 9th, three more small extensive green roofs were installed a top the Academy’s High School Building in Newtown Square, PA.  The High School has a number of glass walled hallways that look out over unsightly black rooftops.  The glass walled hallways provide a spectacular viewing area for the green roofs.  This year we covered almost three times as much roof area as we did last year, bring the Academy’s total green roof count to five.

Once again, Micah from Urban Ecoforms joined us to lend his experienced hand at installing green roofs.  From the picture below you can see that Micah was in rare form and simply thrilled to be freed from his recent solitary confinement atop his current project in West Philly.

While we were installing the green roofs, we could not help but stop and admire the incredible lushness of the green roofs we installed last summer, especially when last July was brutally hot and dry.

Green Roofs and Stormwater Fee

Green Roofs Can Reduce Stormwater Runoff, Reduce Stormwater Fees!

By: Rebecca Gullott

Not many Marylanders are happy about paying the new stormwater fee or “rain tax” as it has come to be known. The county imposed fee is based on the amount of impervious surface such as rooftops and driveways on each property (cost-by-cause principle). In Howard County alone there are over 19,000 acres of impervious surfaces that contribute to pollution of local streams and the Chesapeake Bay. 19,000 acres are almost 30 sq miles or 11% of the counties size- more than double the size of all water ways in the county! No wonder that Stormwater runoff is responsible for over 20% of pollution into the bay.

Those wishing to lessen their stormwater fee can reduce the impervious surface area on their property through smart design and management practices. Howard County is providing instruction and incentives for citizens to do just that. Howard County Stormwater Management Division has partnered with several organizations including the University of Maryland Extension to help citizens take control of their environmental impact. Rainscaping workshops will be offered this summer to show residents how to plant and maintain rain gardens and native species; as well as compost waste and use rain barrels to collect roof runoff for use in lawn and garden irrigation or car washing. Howard County is offering free rain barrels at the Alpha Ridge Landfill select Saturdays April through September. Other Maryland Counties have similar programs so check your county’s website to see what offerings are available.

Property owners can receive credits for on-site improvements that reduce impervious surfaces. Whether it’s establishing a rain garden in the yard or incorporating planted areas or green roofs into the company’s parking lot, these incentives may encourage citizens to take control of their environmental impacts. These changes may help to reduce the need for future stormwater fee increases and promote a healthier Chesapeake for years to come.

The possitive impact for the environment by implementing cost-by-cause fess is very effective in many other counties and States in the US and over decades in Europe.

The Solar Boom

It is obvious the solar industry has been growing steadily, but an ongoing study by the Solar Foundation has uncovered to the extent in which the industry has expanded thus far. Solar workers now outnumber many of our larger occupations in the United States. Currently, we have more solar workers than coal miners in America, and the industry hasn't seized growth yet. The Solar Foundation released an interactive map naming the top three states with the most solar jobs as California, followed by Arizona and New Jersey. Most of these jobs are listed as installation positions, but others include manufacturing, project development, sales and distribution.

The new integrated Sun-Root™ System can help achieve both clean energy production along with additional benefits of a green roof. The Sun-Root™ System is the most advanced system solution that considers both enhanced water storage for the green roof plants and optimized evaporative cooling for solar panels.
