Green Roof Basics Aesthetic Benefits

• Green roofs are much better looking than asphalt or tar. • Natural views create more productive, healthy, happy, creative, relaxed people. • Green roofs expand the usefulness of buildings via patios, gardens and vistas.

Environmental Benefits Urban Heat Island Mitigation

The urban heat island effect is the temperature difference between urban areas and their rural surroundings. The temperature differential causes air currents and dust, and even contributes to violent weather events within urban settings. Green roof vegetation helps by cooling the air, slowing air movement and acting as a substrate for pollution to settle out and detoxify.

Noise Reduction

Plants, soil, and air trapped in the soil are great acoustic insulators. Tests indicate that green roofs can reduce indoor sound by as much as 40 decibels, which is of great benefit to occupants of buildings affected by airports, industry, trains and traffic.

Fire Prevention

Succulent green roof plants help reduce the risk of fire.

Water Conservation/Reduction of Storm water Runoff

The soil in green roof systems acts like a sponge and absorbs excess rain water. Research has shown that extensive green roof systems can reduce runoff by up to 95% following a 1” rain. Green roofs reduce the impact of each new building on the municipal storm drainage system and surrounding watershed. They reduce flooding, erosion and artificial heating of water which helps preserve fisheries and other aquatic life. Green roofs reduce the need for on-site storm water management systems. When combined with an effective rain garden (bioswale), green roofs can make it possible to have zero discharge of rainwater from the site, therefore saving money by not having to connect to the storm sewer system. Green roofs filter water prior to returning it to the aquifer. They buffer acid rain and remove nitrate pollution as water slowly percolates through the soil. What runoff remains will usually occur hours after peak flows, providing additional time for sewer systems to handle the runoff burden from impervious surfaces.

Habitat Recreation

Plants and soil help recreate habitat for butterflies, insects, songbirds. 2

Financial Benefits Political Correctness

With an emphasis on recycled components, energy conservation, sustainability and minimal environmental impact (via development), green roofs score points with city planners, the community and tenants. This is oftentimes rewarded with zoning that allows for more intensive development and higher selling and rental prices.

Conservation of Municipal Septic Systems

Sponging up excess rainwater means municipal septic systems do not have to be expanded as much. It also means reduced overflows as well as accompanying pollution and associated costs.

Extension of Roof Life

Plants and soil act as a protective shield from the elements. This means: • No U.V. radiation/photo degradation of roofing components. • Minimal thermal contraction and expansion (green roofs can reduce temperature fluctuations by as much as 90%). Studies show that on a sunny 95°F day, conventional rooftop surfaces can reach 175°F. Green roofs bring these temperatures in line with the ambient air temperature. • Protection from drying winds. • Protection from mechanical damage. • Reduction or elimination of cracks and leaks.

Ed Snodgrass

Emory Knoll Farms Grower, Lecturer, Author, Green Roof Expert “Both N.C. State and Penn State have shown measurable and quantifiable benefits from extensive green roofs in both storm water detention and retention. There has also been a dramatic reduction in the surface temperature of the roof which in turn extends membrane life and lowers the temperature of the air around the building.”

Energy Conservation

The evapotranspirative effect of the plants and four inches of growing medium typically reduces indoor temperatures 6 to 8 degrees during warm/hot weather and can reduce air-conditioning costs 25 to 50 percent in single story buildings. This not only allows for ongoing cost savings but an initial reduction in the size of the required air conditioning equipment. Minimal insulation (R-Value) exists during cool or winter weather. The pore space of the growing medium tends to be more water saturated at this time, and the plants won’t be as large and therefore will not trap as much air (essential to insulation value). But, in snowy winter locations, the vegetation helps to trap blowing snow which adds insulation value.

LEED Leadership in Energy and Environmental Design How the LiveRoof® System Interfaces with LEED Certification Leadership in Energy and Environmental Design (LEED) is the green building rating system developed by the United States Green Building Council (USGBC). The LEED system’s intent is to provide a standard certification process that registers and quantifies buildings for design and construction methods that promote five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. LEED provides a roadmap for measuring and documenting success for every building type and phase of building lifecycle.

LiveRoof® and LEED Certification Points

The LiveRoof® System can help you achieve LEED certification in several categories–above and beyond that of just any green roof system. LiveRoof® can actually enhance LEED ratings in categories that might not usually apply to a typical green roof. Below are the major categories of the USGBC rating system and potential points that can be influenced by the LiveRoof® system.

Sustainable Sites

If you think about it, wherever there is a building, there once was some type of vegetation. Green roofs help to reclaim green space, and in the process they provide habitat (for songbirds, butterflies and a host of other invertebrates) and help to promote biodiversity. Potential Rating: 1 point.

Storm water Management

LiveRoof ® systems help to prevent excess storm water discharge. They also help to filter and detoxify storm water by removing suspended solids and other pollutants. Potential Rating: 1 to 2 points.

Urban Heat Island Effect

LiveRoof ® significantly reduces roof temperatures during the summer months, and the USGBC specifies green roofs as a means of mitigating the urban heat island effect. Potential Rating: 1 point. 4

Water Efficiency/ Water-Efficient Landscaping

When vegetated with drought resistant LiveRoof ® plants, LiveRoof ® installations require little or no irrigation. Additionally, LiveRoof ® growing media acts as a sponge to collect excess rainwater. Any runoff can be channelled into a cistern for reuse on the LiveRoof ® or other parts of the landscape. Potential Rating: 1 to 2 points.

Energy and Atmosphere

Green roofs of the same depth as the LiveRoof ® system have been documented to reduce energy demand by up to 50% annually in certain types of structures. More typically, green roofs have proven to substantially reduce the need for air conditioning, and therefore require smaller cooling systems, lower capital costs, and lower operating costs. Potential Rating: 1 to 8 points, depending on total energy reduction as a percent versus conventional buildings of the same size.

Materials and Resources

The LiveRoof ® system acts as a protective umbrella over the roof membranes and therefore can substantially extend the useful life of the roof and contribute to the LEED reuse objective. Potential Rating: 1 to 3 points.

Local Sources

LiveRoof modules are manufactured within a 15-mile radius of distribution. Also, since plants are obtained at local nurseries, LiveRoof ® may contribute to the 50% extracted regionally credit. Potential Rating: 1 to 2 points. ®

Recycled Content

LiveRoof ® modules are constructed of 100% recycled polypropylene which exceeds the LEED target of 5% or 10% of project components. Potential Rating: 1 to 2 points.

Rapidly Renewable Materials

LiveRoof ® plants are harvested within a 10-year cycle (actually much shorter), and therefore contribute to this objective. Potential Rating: 1 point.

Innovation and Design Process

LiveRoof ® systems may qualify for innovation and design credits by helping to create a better work environment. LiveRoof ® installations can be used for meetings and relaxation, and maybe more importantly, they create beautiful vistas, beneficial to people’s health and state of mind. Additionally, green roofs can reduce exterior sound by up to 40 decibels and therefore create a more peaceful and less stressful interior environment. Potential Rating: 1 or 2 points.

Guy Bazzani

Bazzani Associates

“Putting a green roof on a building not only helps reduce cooling costs and manages storm water runoff, but also extends the life of the roof itself. At Bazzani Associates we believe that green roofs are an integral part of achieving triple bottom line success in our development projects; in other words, economic viability as well as environmental stewardship and social responsibility.”

Pictured: Guy Bazzani (right), President, and Nathan Gillette, Architect, both LEED AP Bazzani Associate’s East Hills Center in Grand Rapids, Michigan is the first project to receive Double LEED Gold Certifications in the Core and Shell and Commercial Interiors Categories from the U.S. Green Building Council.

Habitat Restoration

This applies to previously developed sites. LiveRoof ® may be used to restore a minimum of 50% of the site area (of impervious surfaces) with native or adaptive vegetation.

Money Savings

LiveRoof ® modules help to save money which can be applied to other sustainable building methods in other areas of the project.

The Bottom Line

The bottom line is that the LiveRoof ® system can contribute to over 20 LEED certification credits, depending on the size of the green roof and the degree to which the various features described above are incorporated into the overall building design. 5

LiveRoof ® System Benefits Why Use LiveRoof® System for Your Green Roof? LiveRoof® is an Instant Green Roof.

Each LiveRoof ® module arrives to the job site with fullgrown plants inside the container and is simply set in place on the rooftop. The unique patent-pending soil elevators are then removed for a seamless fit. No need to start with a brown roof and farm it for years, waiting for it to become a green roof.

LiveRoof® Saves Money.

Pre-vegetated modules discourage weeds and save the time and money traditionally required to develop and maintain a green roof grown from plugs, seeds or cuttings. Other systems may require three or more years for establishment and intensive care is needed during this time period. Well-established plants and roots mean an instant green, successful, and instantly functional green roof.

Designed and Developed by Experts.

LiveRoof ® is grower developed by horticulturists in a collaborative effort with experts in the fields of logistics, architecture, manufacturing, construction, greenroofing, and ergonomics. The LiveRoof ® system, from its effective drain slots to its unique patent-pending Soil Elevators™ and Moisture Portals™, is specifically designed to grow plants on a rooftop environment.

8

Easily Handled and Transported.

LiveRoof ® modules are ergonomically designed so that one person can transport fully vegetated modules, making them logistically ideal for even high roofs that are difficult to access. And if the roof ever needs service or modification, one simply lifts up the modules to access the roof.

Positive Drainage for Healthy Roots.

The drain slots in LiveRoof ® system are located at the very lowest point in the container. They extend up the sides of the pedestals for effective drainage. There are no water reservoirs to cause root rot.

Beautiful Day One with No Ugly Seams.

LiveRoof ® modules fit snugly together and are sealed tightly by soil and plants through the use of patent-pending Soil Elevators™ and overlapping design. This makes the edges of the system invisible for a seamless instantly green rooftop offered by no other modular system. LiveRoof ® Moisture Portals™ allow for moisture, soil and root cohesiveness. Other modular systems show unattractive plastic or metal seams. Such systems may eventually mature (the plants) to the point where seams are obscured during the summer months, but only to reappear during dormancy periods (fall, winter, and early spring) every year.

LiveRoof® Eliminates the Risks Associated with Brown Roofs.

Traditional green roof methods of planting 2 1/4 inch wide plugs on 9 inch centers equates to 95% brown roof (exposed soil) and only 5% green roof (plant material). These traditional brown roof plantings are prone to wind and water erosion and weed encroachment. A brown roof also absorbs heat and diminishes the benefits of a green roof.

LiveRoof ® System vs Conventional Green Roof and other Modular Systems How Does LiveRoof® Compare to Other Green Roofs?

The LiveRoof ® system is superior in design and implementation to both conventional green roofs and to other modular green roof systems. Specific benefits include a better aesthetic presentation and instantly functional evaporative cooling (instantly green vs. brown and no multi-year grow in period), substantially lower maintenance, elimination of wind and rain erosion, simple installation, expertly engineered soil and plant selections, durable indefinite-lasting components, and the pride and peace-of-mind in knowing that the project is successful. With these advantages, LiveRoof ® clearly represents the best value in green roofing systems.

LiveRoof ® Common Questions What’s so special about the LiveRoof® system?

With its unique patent pending Soil Elevators™ and Moisture Portals™, the LiveRoof ® system gives you the look and function of a conventional green roof “membrane” system, with the turn-key benefits of a modular system. LiveRoof ® represents the best aspects of modular and conventional green roofs combined in one simple, attractive effective system. LiveRoof ® is an integrated system designed by growers in conjunction with experts in the fields of architecture, roofing, logistics, and ergonomics. It is designed to grow plants! Composed of recycled plastic materials, LiveRoof ® is based upon sound horticultural principles. It is earth-friendly, as well as rooftop functional and aesthetically pleasing. LiveRoof ® systems, because they are pre-vegetated at the nursery, require minimal maintenance. Compared to sitebuilt green roofs, which are time-consuming and costly to install and maintain, LiveRoof ® offers a turn-key alternative that doesn’t require you to be a horticulturist. LiveRoof ® modules can be vegetated with various plant assortments to address your particular design needs and climate. And if there is ever any need to make changes to the roof, LiveRoof ® modules are easily moved aside and replaced after the work is done.

LiveRoof® Basics

12

LiveRoof ® is simple, effective, efficient and modular. LiveRoof ® is effective for commercial, industrial, governmental, and residential applications. LiveRoof ® works on flat and low slope roofs (typically less than 15% slope) and is incredibly convenient. LiveRoof ® modules arrive to the job site fully vegetated and ready to install. Constructed of recycled plastics, LiveRoof ® modules are easily brought to the roof by conveyor, crane, fork lift, or elevator. Designed for maximum ergonomic efficiency, even very large LiveRoof ® systems can be installed in just a few days. LiveRoof ® modules are simply placed on top of an appropriate smooth-surfaced slip sheet and enclosed by the parapet or within an attractive and functional nonfastened (to module) edging.

What is the biggest financial advantage of LiveRoof®?

Extension of the lifetime of the roof; typical estimates are that a green roof extends the lifetime of a roof between 100 and 200 percent, by protecting the rooftop from ultraviolet radiation, large temperature fluctuations, drying winds, and punctures. Not only does the roof last longer, but there is reduced membrane maintenance. All this brings about significant cost savings over time.

Energy savings What Can I Expect?

Green roofs have been proven to bring about significant energy savings, particularly during the summer cooling season in which single story buildings can experience a reduction of greater than 25% energy use. Plants transform heat and soil moisture into humidity, to create natural evaporative cooling.

Bazzani Assoc. green roof at East Hills Center in Grand Rapids, Michigan

Why doesn’t the LiveRoof® system use filter cloth? And, won’t the soil run out the drain slots?

Filter cloth, like any filter, is designed to filter. Filters in time can plug up (think of your car’s air and oil filters, your furnace filter, coffee filter, etc.). When a green roof filter plugs up, then what? Hint... bathtub (ok for water lilies, but not ok for green roof plants). Because of the aggregate nature of LiveRoof ® soil, the soil stays in the LiveRoof ® module as it would if you poured it into a funnel. It’s like the square peg in a round hole scenario. In addition to this simple act of physics, the roots of your LiveRoof ® plants bind the soil together and hold it in place.

Why doesn’t the LiveRoof® container have moisture reservoirs?

Because it was designed by horticulturists. Horticulturists know that moisture reservoirs store water. Stored water is oxygen deprived, and roots sitting in oxygen deprived water become diseased with fungal and bacterial rot. This weakens the plant, may spread to the crown of the plant, and may perpetually handicap the plant and predispose it to secondary disease and insect infestation.

What is so special about LiveRoof soil?

Unlike cheap soils that are marketed as light weight, and packed with peat moss and perlite, LiveRoof ® soil is predominately composed of

high quality inorganic aggregates, contains a special clay particle to bind nutrients, contains an acid rain buffering component, and is formulated with disease suppressive organic material at a level that is consistent with ecologically sustainable soil/plant communities. LiveRoof ® soil is designed to last indefinitely and to not substantially shrink over time. Cheap mixes with high levels of peat and compost will decompose and wash away as humic acid. Perlite after several freeze thaw cycles may shatter repeatedly and turn to dust. It may also float to the soil surface after heavy rains, then blow away when conditions are dry and windy.

13

LiveRoof ® Common Questions How much does the LiveRoof® system weigh?

The LiveRoof ® system weighs approximately 27-29lbs./sq. ft. (with a media depth of 4”) when fully vegetated and saturated. The LiveRoof ® soil follows FLL standards, enhanced to reflect current research regarding sustainable organic content. We have intentionally avoided excessive organic content, which will shrink excessively over time due to decomposition. Likewise, we have avoided perlite which may break down during the freeze thaw cycle.

Can I retrofit my existing building?

It depends on the load capacity of the existing building. Also, some older buildings can be redesigned for the additional weight of the LiveRoof ® modules. Inquire about our new 15lbs./sq. ft. system for retrofit projects. A qualified engineer must always conduct a thorough analysis.

Does LiveRoof® need irrigation?

The need for irrigation (beyond normal rainfall) will depend upon the plants selected, the local climate, and specific weather patterns. Under normal circumstances, supplemental irrigation is seldom if ever required. Even so, we suggest a backup irrigation system in the event of prolonged hot, dry, windy, sunny weather. During very long bouts of dry weather, plants can go dormant, shrink up, and expose soil. This can increase maintenance requirements as weeds can become established in bare soil. Excessively dry soil also causes the evaporative cooling effect of the green roof to be reduced. Irrigating, even once per month during protracted dry weather, can keep your green roof looking its best and pay dividends through maintenance reductions and evaporative cooling. Irrigating during protracted hot dry weather is a personal choice, the cost is minimal and one has the piece of mind that if ever needed, the water will be there. Backup irrigation systems can range from spigot and hose to overhead irrigation (similar to what one might have in one’s yard.)

What are the best plants to use with the LiveRoof® System?

Those that have extreme drought resistance through some means other than the root system. This means succulent, water-holding plants like Sedums, Alliums, Sempervivums, Delospermas and a few others. The best LiveRoof ® plants will both store water and have a special type of metabolism called ‘Crassulacean Acid Metabolism’, CAM for short. CAM plants are unique in that under drought conditions their stomates (leaf pores) are open at night rather then during the day, as is the case with most plants. CAM plants exchange gasses (oxygen and carbon dioxide) in the dark when it is cooler and less windy. CAM plants are up to ten times more efficient with water conservation than non-CAM plants. LiveRoof ® plants have been selected for extreme drought tolerance, disease and insect resistance, long life, low maintenance, and beauty. LiveRoof ® plants are planted in the LiveRoof® modules at Hortech and other nurseries and cared for until shipped to the job site. Plants are selected by local horticulturists in order to meet the above objectives as well as the local climate and customer preferences. 14

Testing of suitable LiveRoof® plants.

What is the urban heat island effect?

Simply put, it is the temperature difference that exists between urban areas and their surroundings. Urban areas tend to be from 7 to 10 degrees hotter due to the concentration of heat-absorbing buildings, pavement, and hot air from cooling systems. The bubble of hot air that encloses cities is in large part due to lack of vegetation and is a great contributor to smog, ozone and dust (from artificially created air currents from the rising hot air). The urban heat island effect has also been shown to create unique weather patterns within the city, with drought, high winds and electrical storms being more common than surrounding rural areas.

How does the LiveRoof® system help mitigate the urban heat island effect?

Traditional rooftops are usually covered with tar, shingles or stone. As a result, they absorb sunlight. On sunny days with an air temperature of 95°F, city roofs can easily reach temperatures of 175°F or more. The LiveRoof ® system acts like a protective umbrella above the roof to shade and insulate buildings, avoiding the heat island effect associated with traditional rooftops. Plants, of course, release oxygen and evaporate water, a process known as evapotranspiration, and act like evaporative cooling systems to make the air surrounding them considerably cooler. By implementing a LiveRoof ® system, the combined benefit of eliminating the heat generated by a non-vegetated rooftop, along with the evaporative cooling effect, is significant.

How does the LiveRoof® system reduce storm water runoff?

In urban areas, impermeable surfaces (streets, sidewalks, rooftops etc.) dominate the landscape, preventing rainwater from following a natural cycle of absorption. Instead, as much as 75% of the rainwater runs into sewer systems. Carrying contaminates from the air and roadways (salt, oil, mercury, etc.), this water flows untreated into lakes and streams. In some cases, it may cause overflows of sanitary sewer systems, causing the dumping of untreated sewage. In contrast, LiveRoof ® green roof surfaces can absorb up to 99% of a 1” rainfall, reduce runoff, lessen the risk of sewer overflows and flooding, and to some degree filter the water as it percolates through the LiveRoof ® soil. Even when a rainfall is such that it can not all be absorbed by your LiveRoof ® , the excess rain that runs through the media is filtered and delayed until after peak flows, which allows additional time for sanitary sewer systems to handle uncontrolled runoff.

LiveRoof ® Common Questions

Shown as an example of an established green roof. Conventional green roof at Boston World Trade Center.

How does the LiveRoof® system reduce noise?

Plants, soil, and trapped air and moisture in the soil are great acoustic insulators. Studies have shown that green roofs can reduce indoor sound by as much as 40 decibels, a benefit not lost on those that work close to overhead highways and airports.

Where can the LiveRoof® system be used? LiveRoof ® works well on low-sloped (non-pitched) roofs, on industrial, commercial, institutional, governmental and residential buildings. LiveRoof ® works on any building where the building is appropriately engineered and the owners are progressive-minded and value the many economic, environmental, and health benefits that come from vegetated roofs.

Can the LiveRoof® system be used in nonroof areas?

Certainly—median strips, patios, plazas, and malls are also great opportunities to use the LiveRoof ® system.

Can I lift up a LiveRoof® module if I want to access my roof?

16

Yes, it’s relatively easy. First, using a flat bladed shovel, probe the planting to locate the container edge. Then peel away some plant material. This is easy to do as the root systems of LiveRoof ® plants is fibrous and easy to separate (not at all like sod). Using a sturdy pair of pliers, lift up and remove the exposed module. Any additional modules may be removed by trimming around them with the handle of a spoon and lifting them up. Once you are finished, replace the modules. Note: Never use sharp intruments around roof membranes.

What incentives are available for green roofs?

As energy demands rise and smog and other pollution impacts our cities, many cities and states are encouraging “green” building methods, including green roof systems. Cities also encourage green roofs to reduce storm water surges, to protect the ground water, lakes, and streams, and to conserve energy. Of course, incentives vary from city to city and state to state, but it is not uncommon for owners of buildings with green roofs to be generously rewarded. The city of Portland, OR, provides financial, technical and educational incentives to participants through its green roof initiative. Washington, Illinois, New York, Montreal, California and Maryland have also implemented incentive structures. Cities all across North America are following suit, and grant money is often available for the energy conservation and air and water quality benefits that green roofs bring. Be sure to check with your state and local governments to see what is in place in your area. Don’t assume that nothing is available. States and municipalities benefit greatly from green roofs, and often provide tax credits, avoidance of fees assessed for impervious surfaces, grant funding, and/or favorable zoning to encourage their development.

Can LiveRoof® modules be cut to fit odd dimensions and angles?

Yes, LiveRoof modules can be cut to size and shape, either while pre-vegetated or empty with the use of a band saw or reciprocating saw. When installing custom cut LiveRoof ® modules, the cut side should abut the noncut side of another module, in order to contain the soil and minimize the work of installation. ®

Can I walk upon my LiveRoof plants?

Yes, you can do this a couple times a week without causing permanent harm. If you want to pamper your plantings and avoid foot prints, make yourself a small pair of “snowshoes” out of plywood. Make them about 8 x 14 inches and attach some elastic cord to strap them to your feet. This will spread out your weight and protect your plants. Note: Be careful walking in such “shoes”, it will be a bit awkward and you don’t want to fall off of the roof. Always follow OSHA guidelines: “tether” yourself when working near the roof edge.

Customer Feedback

Please email your comments, suggestions, ideas and experiences to us at [email protected].

If the cut side ever abuts edging, it should not be edging that is located on the low, draining side of the roof. Always fit modules tightly against edging or parapet or surround with drainage fabric for added security.

The roof is to be inspected and determined ready to accept the LiveRoof® modules by a Technical Representative of the Installer. D. Once the LiveRoof® installation is completed, an inspection is to be conducted by a Technical Representative of the installer to verify that the LiveRoof® modules have been installed tight against each other, in straight rows, properly oriented, and tight against the edging. 1.4 OPTIONAL MATERIALS Irrigation System A. LiveRoof® recommends the installation of an overhead type irrigation system (similar to that used on athletic turf ). System to be used only to keep LiveRoof® in optimal condition during unusual prolonged periods of intensive heat and drought. Such a system also provides the means to optimize the evaporative cooling effect of LiveRoof® during such weather events. Pavers/Ballast A. To be of compatible size, design, and appropriate weight. Edging A. LiveRoof® Permaloc® co-engineered unaffixed edging recommended.

PART 2: PRODUCTS 2.1 LiveRoof ® MODULES A. LiveRoof® modules are formed of 100 mil. thick (sidewall) recycled polypropylene and colored black. LiveRoof® modules measure 1 foot x 2 feet outside diameter, 3 inches tall. The LiveRoof® Soil Elevator™, the insert collar that allows for growing soil above the container edge, is approximately 3 ½ inches tall, 18 mil. thick, and composed of gray recycled polypropylene or suitable biodegradable material. Each module is to be filled to the top of the Soil Elevator™. Height from container bottom is approximately 4 inches, although normal settling is to be expected and will reduce this height somewhat. B. Saturated weight with mature vegetation: approximatily 27-29 lb. per square ft. C. Module clearance above roof deck: ½ inch. D. When prevegetated at a Nursery, the Nursery is to execute the following: 1. LiveRoof® Soil Elevator™ is to be properly inserted into fasteners inside LiveRoof® module. 2. LiveRoof® module is to be filled with LiveRoof® soil and appropriately settled either by mechanical vibration or flooding with water. Any settled soil is to be replaced so that LiveRoof® soil extends to top of Soil Elevator™ at time of planting. 3. LiveRoof® module is to be filled with LiveRoof® plants, selected by purchaser. Plants are to be grown to maturity (approx. 95%+ soil coverage).

C. On the job site, LiveRoof® modules are to be handled to prevent damage to the modules themselves and all roofing components. D. LiveRoof® modules are to be conveyed to roof surface with equipment that is designed to carry the collective load of the LiveRoof® modules and transport vehicle or Hoppit®. Account for decreasing load limits when boom (of crane or fork lift) is extended. Use crane stabilizers and take all necessary precautions to protect building and personnel. E. Never exceed the load capacity of the roof deck when placing LiveRoof® modules on the roof. F. When suspending LiveRoof® modules and conveyance vehicle above deck, take precautions to stabilize vehicle and prevent twisting of conveyance vehicle. A four inch thick sheet of styrofoam is recommended. G. Surround area below conveyance vehicle and/or crane with caution/stay clear tape to prevent potential injury. H. During installation, protect the roof deck and membranes with appropriate material such as plywood sheeting. Never scrape or puncture slip sheet or membranes. Keep roof surfaces free of soil, grit, or debris at all times with blower or broom. Never set LiveRoof® modules on top of soil, dirt or grit. I. Transport carts to have pneumatic tires, to be wheeled about only upon protective plywood sheeting, and to be loaded so as not to exceed weight capacity of roof deck. 3.4 SAFEGUARDING SYSTEM INTEGRITY Before working on roof, all Installers and Laborers to be:

biodegradable Soil Elevator™ is used, then Soil Elevator™ is left in place. C. LiveRoof® module installation to be conducted in accordance with landscape design. D. LiveRoof® modules to be placed directly on top of appropriate slip sheet/root barrier. E. It is recommended that any custom cutting/fitting be oriented on the high side (top), or sides of the roof. It is recommended that the cut side of the module be set tight against the edging or toward the side of an intact module so as to prevent soil spillage. If custom cutting must be done on the low, draining, side of the roof, it is imperative that no filter cloth be inserted as it could impede drainage. It is best to orient the cut side against another module, facing upstream. F. After installing modules, they should be immediately watered so as to thoroughly moisten the media from top to bottom. Water shall be of suitable quality for plant growth and irrigation system or hoses and sprinklers may be used for such purpose. Note: it takes approximately 1 inch of water, or 11/4 gallons per module to moisten each module thoroughly. 3.7 MAINTENANCE A. Thereafter, water modules only during extended hot, dry weather when plants actually show signs of wilting. B. Check system bi-weekly for weed intrusion, and immediately pull all weeds. Never allow weeds to flower and set seed.

2.2 GROWING MEDIA

LiveRoof ® Development Team David MacKenzie

Hortech, Inc./LiveRoof, LLC LiveRoof® project leader, Horticulturist, Lecturer, Author

Founded in 1983, Hortech is a wholesale nursery specializing in beautiful, utilitarian labor saving turf alternatives. During the late nineties, as green roofs began to creep into the United States, Hortech began to supply sedum plugs for small green roof applications. Then, after the turn of the century, we were propelled rapidly forward in the green roof market as a supplier and consultant to Ford Motor Company for their world-record ten acre green roof. Shortly thereafter, we were asked by a Chicago-based client to design a superior modular green roof system, from a grower’s perspective. We quickly realized that such a system must be more than just plant-friendly, so we pulled together a gifted team consisting of green roof expert Ed Snodgrass, manufacturing and marketing professionals, architects, engineers, roofers, logistics professionals, soil experts, edging experts, and a physical therapist (for ergonomic considerations). Collectively, we have developed the LiveRoof ® system which we believe is the finest modular system in the marketplace. LiveRoof incorporates unique patent-pending Soil Elevators™ and Moisture Portals™, and effective drainage and ergonomic design to provide the look and function of a continuous membrane system with the turn-key instantly vegetated convenience of a modular system. This is exciting since mature vegetation keeps out weeds, prevents erosion and saves a great deal of money as one avoids the high maintenance cost of the typical 2 to 4 seasons for establishment. ®

We look forward to talking to you soon about the LiveRoof ® System and hope to be part of your green roof plans.
