Year-round Benefits

In the first part of our winter green roof series, we wrote about my residential green roof of nearly 12 years. We described how the hardy, lightweight system made it through the winter and how the sedum vegetation adapted to the cold. In this second part, we will discuss a couple of the green roof systems’ year round benefits – how they save energy and help manage stormwater in the winter.

Cool in the summer, Warmer in winter

A research study showed that typical extensive green roofs can reduce heat flow through the roof by 70-90% in the summer and 10-30% in the winter compared to a regular roof.  In the summer, when the sunshine hits the roof membrane, some of the incident heat is reflected but most of it is conducted through the roof into the building, thus the need for air conditioning.  Naturally, added insulation and a reflective roof coating can help reduce the heat gain.

Green roofs reduce the heat gain through the roof  in four ways:  shading, insulation, evapotranspiration and thermal mass.  The plant materials shade the roof to keep it cool.  Water evaporates from the growing substrate and the plants and cools the roof – similar to what sweating does to our skin.  The growing substrate provides some insulation but mostly acts as a thermal buffer to moderate the heat flow – taking up energy during the day and releases it back to the atmosphere in the evening.  This cools our building in the summer.

Green roof traps snow, good insulation

In the winter, the frozen vegetation helps trap snow, a good insulation, on the roof.  As the green roof freezes during winter dormancy, air trapped in the media void space reduces convective heat transfer by the cold winter wind on the roof surface.  The additional thermal mass reduces thermal fluctuations and heat loss from my studio.  I am happy to know that my green roof, despite the plants being in dormancy, still saves on heating in the winter, although not as much as it cools in the summer.

Spring is on its way! Snow Melt and Runoff

Stormwater management is perhaps the biggest driver for green roofs in North America right now.  During heavy rainstorms, runoff from roadways and rooftops often overwhelms storm sewer infrastructure causing flash floods and combined sewer overflow (CSO).  These damage buildings and infrastructure, and pollute our waterways.

The plants and growing substrate in green roofs soak up the rain, reduce the peak flow and runoff volume.  The stormwater management potential depends on the green roof buildup such as the type of vegetation, the growing medium depth, incorporation of retention and detention components and the climatic conditions.  A research study showed that typical extensive green roofs can reduce the annual runoff volume by 57%.

Stormwater runoff is not usually a major concern in the winter as everything is frozen.  However, melted snow produces considerable runoff in the spring and can add burden to our sewer infrastructure.  Green roofs, having larger frozen mass, take longer time to thaw.  Remember how long it takes to thaw a frozen turkey at Thanksgiving?  Compared to a regular roof, the snow on a green roof will melt slower and delay runoff. It stretches over a longer time, depending on its buildup and the climatic conditions. Hence, relieving the burden on the sewer infrastructure during snow melt in spring.

My green roof is still doing its job helping the environment in the winter, even if at a reduced degree.  As I write this blog, I cannot stop thinking about the hardy sedum resting quietly under the snow blanket.  They will soon bounce back to life again as they have for the past 12 years – signaling a new beginning.

Construction schedule and handoff deadlines sometimes push green roofs towards seasonal freezeouts.

Many think of winter as the last time of year you would choose to install a green roof. However, with the proper planning, this season of hibernation and dormancy can yield a great result in spring.

Benefits of Winter Installation

Green roofs installed on mild winter days can benefit from the seasonal timing. Like perennial plants on the ground, all green roofs experience cycles of growth, flowering, and dormancy. During the summer, the plants spend their energy flowering. In autumn, plants divert more energy to root establishment and the sedum plants begin their process of dormancy and energy conservation to ensure their long-term survival.

While fall, spring or an early mild summer can be great times to install a green roof, winter installs will be equally successful as long as some key factors are considered.

CASE STUDY

December Green Roof Installation of Arcade Sunshine Condos 

Stormwater Capture Co provided material and install assistance for a 20,000 sf green roof on Arcade Sunshine Condos, an adapted textile mill and new building structures, in Washington, DC. Phase 1 and Phase 2 of the green roof sections were installed in December – a year apart. While the first phase saw milder winter days in the mid 40’s, the second phase saw mornings starting in the teens and topping out in the mid 30’s.  Green roofs in winter dormancy lose their flowers and change colour, creating a beautiful landscape of reds, browns, and deep purples. Coniferous sedum plants retreat to form a dense mat of glossy and fleshy leaves, while the leaves of deciduous sedum species completely fall off.

Green Roof System: Extensive StormCap Green Roof

Size: 20,000 sf

Phase 1 installation: Oct-Dec 2018

Phase 2 installation: December 17-20 2019

Tips for long term performance

  • Keep an eye on the daily and weekly weather forecast. An 18 degree dawn staging can yield above freezing temps by mid-morning.  For example, Phase 2 of the Arcade Sunshine saw average morning temperatures of 18 degrees fahrenheit at 6 a.m. then heated up to around 38 degrees fahrenheit by noon.
  • Base layers can be installed as long as they are pliable. Filter fabric and retention layer components need to be kept dry and from freezing on the roll. If saturated, they will not thaw easily. However, if there is enough radiant heat from sunlight, these components can shed some superficial moisture and frost by laying them in the sun.
  • As some of these components are dark they will absorb heat which can make them easier to unroll and will evaporate some morning frost.
  • Growing media can be provided in bulk or in super sacks (1.5cy landscape totes). If the media is kept in large hoppers or piles its mass can keep everything but the outer layer from freezing solid well into below freezing temperatures. It is important to move smaller and install media sacks quickly otherwise they can become frozen solid and difficult to work and grade. Radiant heat from a cold but sunny day, helps loosen the media further on the roof to allow for grading and planting.

Sedum Mats Pre-Grown Outdoors Acclimatize Best

  • Sedum mats pre-grown outdoors in a similar climate acclimatize best. On the east coast, mat harvesters will likely close down after new year through March as the ground freezes binding the sedum mats to the ground making harvest impossible. We can coordinate with you to schedule a harvest (and possible short term cool storage) until site conditions and delivery make sense.
  • Pre-cultivated mats should have a minimum of 80 per cent coverage upon installation and should be grown on the farm for 12-18 months to insure a healthy root base and reduce the possibility of erosion of growing media.
  • Ensure vegetation is established upon installation; avoid cuttings or installing plugs in frozen media. During this time of year it’s not worth the time and effort as many cuttings or plugs will dry out completely reducing coverage drastically.
  • If cutting or plugs are used then planting should wait until spring. Base layers and media can still be installed if the conditions allow. A protection fleece should be installed and secured to make sure weed seed banks or wind scour of media is kept to a minimum.

Long Term Survival

Diverse species and sedum selection will better ensure probability of long term survival. Our standard mat option includes many drought and cold tolerant species. We can work with you to provide the best plug or mat options for your specific roof, climate, and design intent.

Foot Traffic and Irrigation

Keep foot traffic over frost-covered plants to a minimum as this will rupture the cellular structure of dormant plants. Consequently, they can suffer disease or die off.

As plants wake out of dormancy in spring, temporary irrigation is important to promote growth. Depending on the climate, irrigate in mid-March or April to get the plants off to a good start but do not overwater.

Climate Change requires an ideological shift in how we think about infrastructure

Hunter French Illustration from Vice Magazine shows a broken sewer pipe craned

Illustration by Hunter French, Vice Magazine

How does our infrastructure interact with the environment? Our drain pipes, reservoirs, power lines, roads, sewage systems, and more are all designed based on past climate data. But with the climate crisis comes the uncomfortable realization that the past can’t predict what we’ll  get in the future.

Design and Build Adaptable, Flexible Infrastructure

Perhaps, it is necessary to consider more adaptable and flexible versions of infrastructure, such as green infrastructure, to meet our modern challenges.

Below is an interesting article that suggests thinking about the consequences right at the beginning of the design process. Engineers and city planners can work to help avoid the failures.

Covid-19 Pushes Construction Deadlines

In early Spring, Covid-19 uncertainty and jobsite safety precautions wreaked havoc on tight construction timelines and Gantt charts across the United States.  For many, deadlines were pushed back.  The anticipated late spring plantings turned into early fall installations.  Ultimately, the Covid delay brings welcome benefits as autumn is an ideal season for plant installation.

Finally Complete with Lush Green Roof

As a stormwater management tool, green roofs are one of the first systems calculated at the design stage by civil engineers.  After years of planning and construction, they are one of the last building features completed.  Now, finally, lush, living green roofs top the finished buildings helping manage stormwater as well as provide other benefits.  To the relief of all involved – designer, supplier, installation contractor and building owner – the planting of a green roof marks the final chapters to construction.

Benefits of Autumn or Winter Install

What some don’t know, is that green roofs installed in autumn or mild winter can benefit from the seasonal timing. Like perennial plants on the ground, all green roofs experience cycles of growth, flowering, and dormancy. During the summer, the plants would be spending their energy flowering.  In autumn, the sedum plants begin their process of dormancy and energy conservation. To ensure their long-term survival they take advantage of the cooler moist temperatures and divert energy to establish roots in their new home on the rooftop.

Tips for winter survival and long term performance

  • Pre-cultivated mats should have a minimum of 80 per cent coverage upon installation to reduce the possibility of erosion of growing media
  • Ensure vegetation is established upon installation; avoid cuttings
  • Use sedum mats pre-grown outdoors in similar climate as they will acclimatize best
  • Diverse species and sedum selection will ensure probability of long term survival
  • Keep the green roof hydrated in the autumn months
  • Avoid foot traffic over frost-covered plants

Next, Maintenance Planning

Now it’s time to change gears from loading, grading, and planting to long term planning.  A maintenance plan is required to keep this rooftop stormwater management tool performing. As with all building systems, nothing is truly maintenance-free. Every component requires periodic maintenance to perform according to the requirements set out during design.

Routine maintenance needs to start near the inception of the project and be carried through to building handover and beyond. A maintenance checklist will include drain inspection and more.  Read this blog on fall maintenance.

Have a Clear Maintenance Plan

The change in seasons and arrival of Autumn requires building maintenance before winter falls. This includes landscapes around and on top of our buildings – green roofs.

The beautiful, living roofs that dot our urban landscape also require care. Some municipalities call for rooftop maintenance such as Washington, DC which requires rooftop inspections twice a year. Furthermore, many warranties are tied to performing maintenance and filing reports. Ultimately, maintenance keeps your green roof performing as it should.

Maintenance requirements can vary slightly with different designs and plant materials. Each assembly should have a clear maintenance plan.

Fall Maintenance Checklist

  • Fall weeding
  • Clean up garbage and matted tree leaves
  • Drain inspection
  • Infill with plugs and mats, as needed
  • Temp or permanent irrigation line blowout (to avoid freezing)
  • Plot your spring game plan, make note of materials or action for following visit

The extent of maintenance above depends on the design, the plant selection, the depth of growing medium, the roof’s exposure and the weather. While it is hard to predict the weather, a designer can opt for a system with low maintenance features to reduce overall labor and cost.  Read more on how to design a low maintenance green roof, here.

Design with Maintenance in Mind

Top Four Design Considerations

 

1. Safe Access

Easy access and safety considerations make for quicker maintenance.

 

2. Lightweight System

Lightweight systems such as StormCap™ achieve desired stormwater management goals and are easy to install and typically require lower maintenance. A thin-layered system with a dense vegetated mat over 2-4″ engineered growing medium tends to be less inviting for harmful weeds and therefore require less routine, manual weeding.

 

3. Plant Selection
Hardy and drought tolerant sedum plants grown outdoors are ideal. Sedum are more resistant to stress and extreme temperatures.  Sedum mats can be successfully installed in autumn or winter months. Maintenance personnel should be familiar with the green roof plants and the owner’s green roof aesthetic preference as some “weeds” might be tolerated in addition to the plant selection.

4. Irrigation
Access to water, with adequate pressure, close by the rooftop is critical for supplemental irrigation in the establishment phase and during periods of drought.

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

 

Finally, here is a link to a graphic novel you may enjoy, The Pollinator’s Corridor by New York City writer and artist Aaron Birk. It tells the story of bringing our pollinators back to the big cities.
