Celebrating Thousands of Green Roofs

Millenia has passed since the marvelous Hanging Gardens of Babylon once existed.  Today, on World Green Roof Day, we celebrate the many thousands of green roofs covering our planet.

 

More than Aesthetically Pleasing

From simple sod roofs to high performing, lightweight detention systems, beautiful, living green roofs are bringing nature back to our urban core. They are pleasing, healing and helping build resilient cities.

 

Stormwater Management to Habitat Restoration

For instance, the main benefits of green roofs are stormwater management and protection from the elements, such as flash floods and extreme heat. Also, green roofs offer habitat restoration, food security and urban agriculture.

Bees are critical to our Ecosystem

 

 

 

 

In the United States, there are over 4,000 species of native bees.  Bees are critical to our entire ecosystem. They are extremely important to humans and help plants reproduce through pollination. A Yale University study reports:

“One of every three bites of food eaten worldwide depends on pollinators, especially bees, for a successful harvest.” Honey bees support about $20 billion worth of crop production in the U.S. annually.

Declining Bee Population; How Green Roofs Help

Declining bee populations pose a threat to global food supply.

While there is no one single factor causing the decline, habitat loss is definitely on the list. Nevertheless, our cities of concrete and glass can take part in providing an urban refuge and help rebuild a declining population.  For instance, provide much needed green space on the rooftop!

Green Roofs Provide Urban Habitat

Green roofs benefit cities in many ways.  In addition to stormwater management, green roofs provide pollinator habitat and mitigate the urban heat island.

Biodiversity in the Urban Corridor

Lightweight, low maintenance green roof systems such as the StormCap™ include a variety of sedum species and can be customized to increase biodiversity.  The pre-grown, flexible sedum mat can easily and seamlessly integrate lightweight extensive systems with intensive systems that offer custom plants, native grasses and shrubs.  Varying depths of engineered growing medium are added under the sedum mat to create topographic variation and increased biodiversity.  StormCap™ with a BioBerm™, for instance, is the perfect solution for pollinators such as bees and butterflies

Green roof installation for stormwater management

Preparing for the Future, Despite Current Pandemic

Cape Cod Tech (north side) shows completed green roof with a wave of maroon pre-vegetated mats integrated with the green.

While the Covid-19 crisis has forced millions of students worldwide to work from home, a team of dedicated essential workers brave cold temperatures and nearly gale force winds to install the StormCap™ green roof system that helps the the new Cape Cod Technical High School prepare for extreme weather and climate change.

Dedicated Workers, Carefully Carry On

Pandemic and unseasonable weather aside, dedicated workers carefully carry on to meet summer occupancy deadlines.

Above all, to ensure everyone’s safety the local fire department took the temperature of each construction crew member at the start of the day. Furthermore, workers wore face masks, maintained health and safety measures and kept a safe distance throughout the day to complete the green roof installation as scheduled and help make this building more resilient to climate change in the future. With the vegetated roof, the building will better manage large rain storms and reduce runoff into sewers and reduce stormwater pollution.

Over the three days, Rodney Chaney, Technical Sales Manager, will be at the NJASLA to answer your questions. For instance, he will measure water retention and detention, as well as heat transfer, and compare to a traditional black roof. It is a great opportunity to get up close and personal with innovative green roof technology.

Touch, feel and witness how a green roof plays a vital role in retaining and detaining rainfall, attenuating stormwater, mitigating the urban heat island effect and reducing the environmental footprint.

Many Benefits of Green Roofs

For example, vegetated roofing systems reduce the environmental footprints the following ways:

Water The green roof helps detain and retain rainfall at its source and control runoff.

Energy saving Through shading, insulation and evaporative cooling the green roof helps reduce energy use.

Climate Green roof reduces flash floods and combined sewage overflow. It addition, it mitigates the urban heat island effect.

Ask us about the latest Innovation in Green Roofs: Detention Technology

Powered by the Purple-Roof Concept, StormCapTM +Detention is a green roof that works to manage stormwater even when it is wet.

It reduces the severity of flash floods by delaying roof runoff during the largest rain events, and it even works when it is totally wet! Rain is temporarily accumulated on the roof which reduces the need for underground cisterns, thus freeing-up valuable underground space that can instead be used for profitable purposes like retail or parking space. SC+D offers property owners a clear return on investment.

Green infrastructure can mitigate stormwater pollution.

Stormwater is the main way pollution gets into the rivers and waterways

A good rainfall cleans the city streets. As a result, all the road salt, cigarette butts, animal feces, antifreeze and other garbage is swept up in the rain and into the storm sewers and our waterways.

Meanwhile, the Sluiceway illustrates how green roof system helps retain and detain rainfall onsite and subsequently mitigate stormwater pollution.

How Green Roofs Help

Volunteers can pour gallons of water onto two sloping platforms.  Platform One will mimic a typical roof and feature a waterproofing membrane and trash that would be found on road ways and end up in the sewers. Platform Two features the StormCapTM pre-vegetated system that collects rainfall and helps with stormwater management.  At the end of each platform a storage bin will collect the “rainfall” and trash.  The audience will witness the performance of the StormCapTM vegetated roofing system and learn why vegetative roofing technology plays a key role in stormwater management.

StormCap™+Detention Helps Mitigate Floods

StormCap™+Detention green roof system is engineered to optimize stormwater  management. It detention tool that mimics watersheds and aquifers to help mitigate urban flooding.

Lessens strain on sewers. 

Decreases combined sewer overflow (CSO).

Detention technology allows the green roof to face second day and extra large storms. It is not dependent on weather to provide a repeat performance and recharges in as little as a few hours.  StormCap™+Detention  stores water temporarily and limits the rate at which water flows from the roof drain.

 

 

Innovative Technology Mimics Nature

Friction in nature includes tall grasses in meadows, dense masses of reeds in wetlands, or layers of leaves on a forest floor. Friction-detention in

vegetated roofs is a technological innovation inspired by nature to achieve rooftop SWM in dense urban areas.

Contact us to help run stormwater calculations specific to your project.

 

 

Clear Return on Investment (ROI)

StormCap™+Detention provides a clear ROI by reducing or eliminating cisterns and bioretention facilities and freeing up valuable space for income-generating development. It even works on a sloped roof!

Stormwater management is unique to each project. Let us start the process and run project-specific calculations.  Contact us for more info.

Other Benefits

  • Provides better plant performance: StormCap™ retains almost double the water of traditional green roofs, and StormCap™+Detention retains about 10-20% more than that! This increases water availabilty for better plant performance.
  • Achieves sustainability goals: StormCap™+Detention is a great way for companies or buildings to show commitment to the environment.
  • Increases real estate values: Green roofs provide usable or visible amenity space that increases rents and real estate value. StormCap™+Detention further increases real estate value by freeing up land
  • Offers greater cooling benefits: All green roofs help cool the building, but StormCap™ and StormCap™+Detention improve cooling by providing more water for evaporative heat loss.
  • Extends roof lifespan: Green roofs buffer the roofing membrane from thermal flux. StormCap™ and StormCap™+Detention do an even better job of this for the same reason that cooling benefits are greater.

Case Study: How the StormCap System is rehabilitating an ailing green roof pioneer and improving functionality for years to come.

The StormCap System is enhanced by Urbanscape for superior stormwater management and plant health.

By Rodney Chaney

The Severn Bank green roof  in Annapolis Maryland (MD) was ahead of its time.  Like many building owners who needed an onsite stormwater solution, this green roof was intended to be a workhorse. With historic rainfall in recent years, it was starting to burn out in sections.  Stormwater Capture Co was invited to inspect the problem and offer a solution to improve its functionality and restore its beauty. Below is the full story about this traditional green roof, now transformed with the StormCap system enhanced by Urbanscape.

Green Roof Pioneer: The beginning

The 13,000 square foot Severn green roof sits atop of a four story parking garage connected to a five story office building.  Its primary purpose was to address stormwater management needs near the historic downtown area of Annapolis – likely one of the first in Maryland built for the purpose of managing contributing stormwater.  Tecta America a pioneer in North American green roofs was consulted and contracted to install the roofing and green roof.   Tecta America has diligently maintained the roof since.

Stormwater Workshorse

For years, the green roof had functioned as designed. This workshorse managed well over seven million gallons of stormwater and maintained a healthy plant palette that the owners in the adjacent offices would look upon with pride.  The amenity space within the green roof area has provided a place to enjoy lunch or take a call alfresco.

Fast Forward A Decade Later: “Houston, we have a problem”

The Severn green roof had been designed to accept the contributing runoff from nearly half of the adjacent 20,000 square foot building roof managing the anticipated rain event. It retained both precipitation and runoff.  This workhorse managed twice the amount of water that fell directly on it. It was a great setup and worked beautifully for over a decade. Then, something happened…

Dealing with Historic Rain Events

Two exceptionally wet summers appeared to have caused the green roof to die in several significant areas. This was confusing as two wet summers should not have been enough to make the roof fail. After all, it had been designed to withstand a good bit of runoff.

In the last several years the region has seen historic rain events.  Many site stormwater management systems and municipal storm sewers have

Although many areas of the green roof were lush with excellent coverage other areas had almost completely burned out and in need of rehabilitation.

been overtaxed.

What went wrong and how to fix it?

As symptoms became apparent the owner and Tecta America were quick to act.  Stormwater Capture Co was asked to provide 3rd party consultation.  At the initial inspection, we were surprised to discover that although many areas of the green roof were lush with excellent coverage other areas had almost completely burned out.  What had gone wrong and how could we fix it? Upon closer inspection, we found several contributing factors.

Green roof with wet feet

The overflows designed to manage the onslaught of heavy flow from the contributing roof area hadn’t provided the fail-stop to keep the roof from “bogging out” for extended periods.   Even with a record of 7”+ rain events there was no evidence that the excess flow was reaching the height of the collar to allow for bypass.  Compounding the problem, the drainage assembly at sumps had been built at a time when drain perimeters weren’t typically installed.  In addition, the biomass of over a decade had accumulated to a point where the additional mechanism of evaporation was slow to dry.  While biomass is good, with these other factors this green roof was left with prolonged periods of “wet feet”.

If the green roof needed to manage only the water falling on it, this system would likely have continued to thrive.  However with this pioneer in contributing drainage, it was necessary to move the stormwater throughout the system more efficiently.

StormCap improves roof functionality and restores beauty

To remedy the problem, six hundred linear feet of perforated drain tile was trenched throughout. The indirect pattern allow for improved movement of water to all areas of the green roof.  Then eight expanded drain sumps were opened and framed with new SCC .063 perforated metal edge, SCC drain board, and ballast. Following this, the overflow on the “high side” of the green roof was adjusted by lowering the bypass collar height.  It was factored that 99% of rain events will be treated by the green roof.  So, even in heavy rain events the overflow won’t be tripped too often.

Upon our inspection, we found that only 3,000 square feet out of the total green roof footprint needed replacement.  This was the center of the green roof that received  the majority of contributing drainage.  We decided to solve this problem using several methods.

StormCap berm hosts deeper rooted natives and adaptives such as rudbeckia, asters, beards tongue, russian sage, lavender, phlox and babtisia.

Re-using Native Plants

After removing 3,000 square feet, we were able to reuse all of the nutrient rich biomass that had been built up over the past 12 years to build semi-intensive berms to harbor some deeper rooted natives and adaptives such as rudbeckia, asters, beards tongue, russian sage, lavender, phlox, babtisia, etc.

Not only did this reuse the existing material and help manage the excess of stormwater from the impervious deck area, it also created a great sightline from the amenity area that didn’t exist before.

StormCap Pre Vegetated Roof SystemStormCap Solution

The removed area was replaced with a high efficiency StormCap 1+3 profile by Stormwater Capture Co. Our proven assembly, consisting of  UrbanScape’s® high-performance needled mineral hydro blanket topped by our pre-vegetated mat, provides a healthy and instantly green roof .  This innovative systems now provides the retention needed and stormwater flow necessary to avoid “the bog” that was causing parts to die out in recent years.

Green again! 

After a few days of prep and a Saturday installation, the result amazed the owners Monday morning when they arrived to work.  Their green roof was in fact GREEN again!  The instant coverage of the sedum mat and the addition of the semi-intensive berms surrounding the amenity space were striking.  Less noticeable but more important than the “instant” coverage was the fact that the green roof will now manage stormwater more effectively and be ready for the sunny days well as the storms ahead.

Proud Green Roof Owners

The functional upgrade, and the addition of new visual interest, gave the owners a greater appreciation of what a healthy green roof can provide environmentally and emotionally.  In this scenario, we were able to solve a problem, add functionality, as well as provide a great new aesthetic to this existing “workhorse” green roof.
