Dedicated to sustainability, NYC Convention Center embodies world-class technological innovation

NYC Convention Center green roof brings nature back to urban core.

The 6.75-acre green roof on the Javits Convention Center makes the 27-year-old building an example of sustainable retrofitting – attracting many species of birds, bats, bees and even tourists who go on rooftop tours.  This NYC landmark is also closely monitored by a team of engineers from Drexel University and The Cooper Union for the Advancement of Science and Art who have designed and installed sensor systems to track its environmental impact.

CEO very pleased with performance of vegetated roof

In a recent interview with NPR (see video below), Javits’ CEO Alan Steel explained the significant aesthetic, environmental and economic benefits of the green roof.

Honey harvested in Fall of 2017 from NYC’s rooftop.

“Besides the great reaction, there are practical benefits.  We have three hundred thousand bees, we’ve seen 25 different species of birds on the roof. We reduced the temperature out here by about six degrees Fahrenheit and we also save about seven million gallons of stormwater runoff that’s absorbed in the  soil and the plants.  We’ve been able to reduce our energy consumption by about twenty six percent and that translated for us last year (2016) into a saving of about three million dollars.”  Javits is now also selling honey harvested from the rooftop.

“The success of our sustainability program epitomizes our rebirth as an organization, and this first batch of honey illustrates how far we have come in our efforts to reduce energy, create a wildlife haven and improve the quality of life in our neighborhood,” said President and CEO Alan Steel.

Green roofs are a learning laboratory for Engineers

Professor Franco Montalto in the department of Civil, Architectural and Environmental Engineering at Drexel College is the lead researcher on the Javits green roof project. He says in recent years the City of New York has made major commitments to sustainability and green infrastructure.

“The Javits Center green roof exemplifies the kind of environmentally sensible urban redevelopment projects that the City wants to encourage. The retrofit building will reduce urban runoff, mitigate the urban heat island effect, and, potentially have a cooling effect on the streets and buildings that surround it. Our research will seek to quantify these benefits,” said Montalto.

Watch NPR feature on Javits

Montalto’s research team is currently also monitoring more than 15 other green infrastructure sites in New York, New Jersey, and Pennsylvania. Students from The Cooper Union will monitor the data and use it to learn about and model functional sustainable design projects.

“The Javits Center green roof project provides Cooper Union students with a significant learning opportunity to study sustainable design and use New York City as a learning laboratory,” said Dr. Joseph Cataldo, a professor in the Albert Nerken School of Engineering at The Cooper Union.  “Our students are presently developing a model to predict the thermal behavior of the green roof using climate and infrared data. This information will be helpful to better gauge hydrology and temperature variations of the green roof, which, subsequently, is an important part of determining and understanding temperature patterns in green roofs and New York City as a whole.”

“Water and energy are intimately linked through the process of evapotranspiration,” Montalto said. “Incident solar radiation changes liquid water, originally deposited on the roof by precipitation, into water vapor which then leaves the roof surface. The energy consumed by this process keeps the roof and building cooler than it otherwise would be, since without the green roof this energy would simply heat up the roof surface. At the same time, if the air in the vicinity of the air conditioner intake pipes is cooler, these units have to work less to cool the -already cooler- building.”

Green roof ‘hail-proof’ while exposed  roofing membrane required replacement

One year ago, the most damaging hailstorm in Colorado history wreaked havoc on cars and roofs and caused $2.3 billion dollars in insurance costs, according to the Rocky Mountain Insurance Information Association.

Dynia Architects designed the 140.,000 square foot FLIGHT building

Denver developer Kyle Zeppelin had hundreds of thousands of dollars in damages to his membrane roofs at his latest office development in The Flight, in the River North District.

“All of the membrane roofing was required to be replaced as a part of the hailstorm,” he said.

While his regular roof had to be thrown out, Zeppelin said he found his luscious green roof – on the same building – was hail-proof.

“The green roof here was left completely intact after the most-recent hailstorm,” he said.

It’s an unseen upside, Zeppelin said, that more than outweighs the upfront costs.

“This is not likely to be the last hailstorm, so there’s that advantage and the green roof provides a significant installation value over just the membrane,” Zeppelin explained. “It’s a win-win as far as [it] makes sense economically, makes sense for the environment, and really enhances the livability of the building,” he said.

How Green Roofs Survive the Northeast’s Bitter Cold, Blizzard and Thaw

Tips for Spring Maintenance and Repair

When it comes to weather, the Northeast US has seen it all this past winter: sub-freezing cold and heavy snow, interspersed with warm dry conditions up to 60°, heavy rainfall, powerful winds, and returning snow storms pounding the region.

With conditions varying quite a bit from week to week, even trees and power lines being felled in high winds, what can we expect from the green roofs high above ground level, invisible to many, quietly doing their job keeping rainfall on-site, among other important environmental functions.

StormCap

Fig. 2 High performing extensive system.

Many question how a vegetated roof can survive winter and how it will perform in the Spring. Some people question how the vegetation looks. Does the bitter cold, wind and snow damage the plants? Will the green roof die?  Can it be walked on in winter months for necessary rooftop maintenance?  Does vegetation need to be re-seeded in the Spring? Important questions, to which solutions start at the design phase.

Vegetated or green roofs, whether intensive or extensive, experience the same cycles of growth, flowering and dormancy that occur to plants on the ground level. Vegetated roofs that are properly designed for climates with four seasons, correctly installed and routinely maintained, have a greater probability of survival no matter the season, and the changing conditions.  This article will focus on lightweight, extensive vegetated roofs, as this is the prevalent type of vegetated system in the Northeast US and across North America. Extensive roofs use shallower depth of engineered growing media up to 6 inches and are lighter than intensive vegetated systems.  Growing medium may be the traditional soil-based or a lightweight needled mineral wool made solely of virgin rock mineral fibres, or a combination of both for best water-retention-to-weight-ratio (see Fig 2). Extensive roofs can achieve excellent water retention and are more economical to install and maintain.

 

Dormancy

In cold Northern climates such as the Northeast US, vegetated roofs start going into dormancy in the Fall to prepare for winter. As rooftop conditions are harsher than at the ground level, the exposed vegetation on rooftops enter into the dormancy cycle earlier than at ground level.

Dormancy is a natural reaction to adverse environmental conditions. It is the plant’s defence mechanism to keep itself alive stopping further growth and conserving energy. It occurs each Fall in preparation for the cold winter. It may also happen in the summer during periods of intense heat and drought, if not irrigated.

Dormancy synchronizes with the environment and can be triggered by a temperature drop or sudden changes in climactic conditions, such as water shortage.

Retreating plants are not dead. Green roofs lose their flowers and change colour in dormancy creating a beautiful landscape of reds, bronze and browns, to deep purples. Coniferus sedum plants retreat to form a dense mat of glossy and fleshy leaves, while the leaves of deciduous sedum species completely fall off.

Designing vegetated roofs to survive

Plant type:

For highest probability of survival, a vigorous, low-growing, drought tolerant plant species such as sedums and mosses is the ideal choice.  These plants are tough and reliable and can withstand harsh rooftop conditions year-round.  Sedums are succulent plants that mostly originate in Northern climates and flourish in harsh conditions. Vegetation that is pre-grown outdoors locally, for several months or over a winter, ensures they are acclimatized to the localclimatic conditions.

Foliar coverage:

Mature vegetation, with excellent foliar coverage (85% and higher), not only offers instant green upon installation but a higher probability of survival with less chance of wind and soil erosion.

Thermal mass:

The needled mineral hydro blanket’s high water retention reduces the need for irrigation and improves plant survivability year round.

Snow accumulation is welcome as it insulates the vegetation.  A blanket of snow shelters the vegetated roof from strong winds and helps the plants retain moisture and the blanket of vegetation shelters the growing medium from wind erosion. In colder plant hardiness zones, or in areas where there are extreme fluctuations in temperature, green roofs require a deeper depth of growing medium to help mitigate the effects of intense temperature and moisture changes.  Additional growing medium acts as a thermal mass helping moderate the temperature and hydrate the plants – helping reduce significant die-back in the winter or during hot summer droughts. Water retention materials such as the needled mineral hydro blanket is used to supplement and replace traditional soil-based growing medium and achieves equal or better water storage capacity while keeping the system weight low.

Wind Uplift:

With the recent introduction of CAN/CSA A123.24 Standard Test Method for Wind Uplift Resistance of Modular Vegetated Roof Assembly, the first

such test standard in the world, it is now possible to ensure you choose the right vegetated system for a specific building or certain elevation.

Repair:

If there is little or no snow accumulation, and the vegetated roof is subject to high winds, extreme fluctuations in temperature or a particularly severe ice storm, plant desiccation, or “winter burn” can occur where the plant dries out and dies. This may expose areas of growing medium that may be subjected to erosion by high winds. If such damage occurs to the vegetated roof, a straightforward procedure for repair can be followed in the Spring. This repair procedure also applies to other vegetated roof repairs due to excessive foot traffic or due to construction materials left on the plants for extended periods of time.

The repair is done in the Spring using a variety of sedum clippings sprinkled, where needed, to replace the sections that have been damaged or eroded.  Succulent plants such as sedums are easy to propagate. Many can be rooted from a single leaf, others will root quickly from a stem cutting. For areas that suffered erosion, additional engineered growing medium should be added, as required. After the initial planting of clippings, frequent, light irrigation is required to keep the vegetated roof moist and help ensure the plants take root.

Installation Tips:

Johnson & Johnson World HQ, New Brunswick, NJ installation in December 2017.

Pre-vegetated sedum mats delivered to J&J site have almost 100% coverage with mature vegetation.

Many vegetated roofs are installed in the Fall due to the construction schedule and desire to finish the project. In such cases, it is critical to have mature and well established plants as they have greater survivability on rooftops than plants that are immature seedlings. The vegetation may have been disturbed during harvest, transport and installation.  Therefore, after installation, it is important to keep the vegetated system hydrated during the establishment period for the plants to recover and take root and prepare for the coming winter.  It is imperative to have water access on the rooftop. Furthermore, good design ensures pavers or ballast is installed to reduce foot traffic and vegetation damage. In cold climates, particularly when temperatures drop below freezing, foot traffic over vegetation must be avoided as it can prove lethal, leaving foot-shaped patches of dead plants. The damage will be obvious the following Spring and recovery may take several months or may not happen at all. If pedestrian traffic is unavoidable, protective measures must be taken to diminish the impact of damage.  Materials like plywood sheets or insulation boards may be laid over the vegetation temporarily to help distribute the weight on the green roof, and removed at the end of each day to allow plants to recover.

Fall & Spring Maintenance:

Year-round maintenance is key to ensuring long-term survivability as well as the stormwater performance of the vegetated roofs.  One last maintenance check should be done in the Fall as part of the yearly routine.  Vegetated roofs are also known for their ability to protect the roof membrane, however, not taking proper preventative measures can also lead to unforeseen problems.

Fall maintenance includes the removal of debris and inspection of all drainage paths.

In Fall, it is best to remove fallen leaves and twigs from the green roof. Thick layers of leaves and twigs can also stick together to form an impenetrable mat and may lock in too much moisture, potentially causing rot or damage to the plants.

Weed, one last time, before winter sets in. Make every effort to capture the seed pod intact and tuck it away for disposal to avoid seeds blowing away.  Some weeds may be tolerated, therefore maintenance personnel should be familiar with green roof plants and the owner’s green roof aesthetic preference.

Keeping the vegetated roof hydrated into the Fall months helps the vegetation avoid winter’s freeze-drying effect caused by low temperatures and high winds.

If there is an irrigation system, it needs to be winterized around October in nothern States as frost typically sets in soon after. Maintenance crews typically use an air compressor to blow out the water from the irrigation system.

Vegetated roofs should not be fertilized past August, especially with a slow release type fertilizer. Fertilization may stimulate tender growth and compromise the hardiness of the plant. Secondly, plants won’t have a chance to fully take up the nutrients and the combination of high temperatures may cause the plants to burn. Slow release fertilizer is usually applied once, ideally in the Spring.

Assess the performance of the green roof in the Fall and prepare for next Spring.  It is a good idea to document  your visit with photos and record recent weather conditions for future reference and any potential warranty claims.

Green infrastructure offers climate resilience in urban environments.

How vegetated roofs alleviate impact of climate change

Vegetated roofs, otherwise known as green roofs, are a key part of infrastructure resilience in an era of extreme heat events and more frequent and intense downpours.

Below are 4 ways vegetated roofs can have an immediate impact to improve resilience:

 

1. Help manage localized flooding

Vegetated roofs absorb rainfall, and help prevent water from overwhelming stormwater sewers and flooding streets or basements.  This reduces damage to infrastructure and property. They also reduce the volume of stormwater that flows into streams and rivers and thus protect local watersheds.

 

Vegetated roofs help mitigate urban heat island effect cooling the building, surrounding air and improving human health and comfort.

Vegetated roofs help mitigate urban heat island effect cooling the building, surrounding air and improving human health and comfort.

2. Help reduce urban heat island 

Vegetated roofs are a natural cover for rooftops that would otherwise absorb and retain heat.  Vegetated roofs mitigates air pollution levels an remove heat from the air through evapotranspiration. On hot days, vegetated roofs, reduce temperatures of the roof surface, and the surrounding air, improving human health and comfort.

 

 

Vegetated roof reduces the heat flux through the roof.

3. Help lower building energy demands 

By shading the surface of the building, the vegetated roof is reducing the heat flux through the roof and reducing the indoor temperatures and demands on air conditioning.

 

 

 

 

Vegetated roofs delay peak flow and reduce pumping and treatment demands for municipalities.

Mastery’s first newly constructed school, Cramer Hill Elementary utilizes the latest approaches in construction technology.

CAMDEN, NEW JERSEY, UNITED STATES — The start of the new school year will be a fresh start, in more ways than one, for the Camden community that the new Mastery Cramer Hill Elementary school will serve.

“This brand new, safe and beautiful facility is one step in the right direction offering a world class education to Camden kids,” says Joseph Ferguson, Chief Operations Officer, Mastery Charter.

“That first day of school, what will really matter to me is that students and parents take pride in the school that was designed and built with them in mind. I want them to take ownership and truly believe this is a place where they can learn, and grow.”

World Class Education for Camden Kids

The city of Camden suffers extremes of poverty, and is reported to have among the nation’s highest violent crime rates. Many kids are in schools that are historically lower performing – in the bottom 10 per cent statewide – some in classrooms with no windows and no natural light.

Happy second-graders at one of Mastery's 24 schools in Philadelphia and Camden.

So impressed with their approach to education, talk show host Oprah Winfrey generously donated $1 million to the Mastery Charter organization.

Come September that will change for up to 750 local students who will attend the new school on East State and River Streets. Ferguson says that when students arrive at their new school, he wants them to “experience joy and great instruction.”

Cutting Edge Approach to Education and Technology

The vegetated roof, a high performing StormCap™ system, will be part of the learning as it is visible from classrooms on two levels. “In the construction of this new facility, the green roof presented a very economical and environmentally friendly stormwater solution,” says Ferguson. “It also provides an educational opportunity. Our teachers are excited and are looking forward to program the space in the future. We want students to be able to appreciate it. We want it to be part of the science program, by explaining why we have it, how it works, and how it helps the environment.”

Panorama photo of the construction of the Mastery Cramer Hill Elementary School vegetated roof.

Architects Kevin Blackney and Troy Hill of Blackney Hayes Architects designed the building. They say the green roof was proposed early in the design process to help with storm water management, and also as a learning tool. “This is Mastery’s first newly constructed school and in keeping with their cutting edge approach to education and technology, they thought it was important to utilize the latest approaches in construction technology,” said Troy Hill. “The green roof technology also gives the teachers the opportunity to use its function and maintenance to supplement their curriculum.”

The vegetated roof and pervious parking reduce runoff and manage stormwater on-site helping keep the local waterways clean. “Like most projects in urban environments with aging infrastructure, the storm sewer in the area is “combined” with the sanitary sewer flows,” explained engineer Charles Chelotti. “During heavy rainfall events, this combined system discharges directly to the local waterways and rivers. For this specific project, although there was net reduction in impervious coverage from the pre-existing condition, it was still necessary to reduce the impact to the “combined” system in the area, some of which may be over 100 years old.”

In addition to superior stormwater management, the vegetated roof offers other benefits for the building and the environment such as cooling the building, prolonging the lifespan of the roof itself, providing natural habitat and reducing the urban heat island effect. Also, research shows that biophilic design has direct advantages to students and teachers as views of natural landscapes from classrooms benefit academic achievement and behavior.

Workers unroll the sedum blanket onto the growing medium.

A team of workers from Ganter Contractors install the nearly 3000 square feet of vegetated roof in less than one day.

Ferguson, who is overseeing the construction of Mastery’s brand new building, is excited, too.

In mid-July under the blazing sun, Ferguson was present to watch workers from Ganter Contractors install the nearly 3000 square feet of vegetated roof in less than one day. “It looked very organized and straightforward. The team knew exactly what they were doing and I was very impressed with how efficient the installation happened.”

With school just around the corner, the team continues to work hard on the finishing touches to welcome new, eager students who will learn to love to learn.

About Mastery Charter Cramer Hill

The most notable development to date in vegetated roofing is the production of the needled mineral hydro blanket – a non-petroleum and formaldehyde-free alternative.

Knauf’s innovative needling manufacturing process provides dimensional stability without use of chemical binders.  The needled hydro blanket is formed by mechanical interconnection of pure mineral fibers.Needled Mineral Hydro Blanket

This process forms a structurally stable, lightweight and porous material with longer fibers that maintains excellent water holding properties. It is consistently hydrophilic, even after various weather cycles throughout the year. Up to 90% of the material retains rainwater. When wet, the majority of the retained water is easily available for the plants uptake.

The water absorption characteristics are not affected over time as nothing rinses away and will remain the same throughout the lifetime of the products.

The Needled Mineral Hydro Blanket is ideal for vegetated roofs, as it:

  • can supplement, or in some cases replace, heavy growing media
  • can act as a water reservoir and support plant health
  • achieves greater LEED credits
  • performs exceptionally and reliably as a rooftop stormwater management tool over the lifespan of the vegetated roof

Needled Mineral Hydro Cubes and Hydro Flocks

hydro cubesThe above needled, binderless, mineral wool also comes in the form of small hydro cubes (about 0.7 cubed) or hydro flocks (0.1-0.7 inch pieces) to mix with traditional growing media.

This is an innovative method of  improveing traditional growing media. Cubes and flocks contribute to better soil structure, water holding capacity and aeration of growing media. The retained rainwater inside the hydro cubes or hydro flocks is easily available for plant uptake, improving plant survivability. Cubes and flocks are specially recommended for patios, terraces and home gardening.

The engineered base layers include Urbanscape’s needled mineral hydro blanket, made solely of virgin rock fiber. This mineral wool has no binders and therefore has superior retention of 90% of water by volume and withstands freeze/thaw cycles.

Most of StormCap’s base layers come in rolls that are easy to transport and install. It is a fully customizable system with biodiversity options using the BioPocket™.
