A brief overview about the green building strategy known as green roofing. This presentation was originally prepared for St. Louis regional educators who attended the 2014 Sustainability Institute for P12 Educators.
In the last five years, the term green roof has taken on ecological and social significance beyond its seemingly simplistic description, this term has become an epithet for the reduction of pollution and improving urban environment, for large scale mitigation of storm water runoff, and for maximum utilization of urban land.
Erbil the capital city of Kurdistan region is facing a lot of environmental problems such as waste water treatment, water supply, land preservation, air and noise pollution due to the increasing number of cars, in addition, interestingly recent statistics suggested that the percentage of green areas in Erbil is approximately 6.5%, while according to international standards 30% of urban areas should be green.
Green roofs infrastructure on the other hand promises to become an increasingly important solution for building owners and community planners which provides a significant numbers of social, environmental and economic benefits that are both public and private nature.
Research problem is the ambiguity of green roofs implementation techniques in the region and the goal is initiated to determine the obstacle and challenges of green roofs implementations in Erbil city as case field by analyzing international experiences and concluding Erbil’s green roofs criteria.
St. Paul Fire Station Green Roof Intrpretive Center and Garden ClassroomLoren Abraham
This presentation provides details of the design and construction of the St. Paul Fire Station Green Roof Interpretive Center and Garden Classroom completed in 2010. This green roof was part of a 58,000 sf firestation and fire department headquarters building for the city of St. Paul, Minnesota. The green roof was designed by Abraham + Associates Architecture and Planning, who was also the sustainable design and LEED consultant on the Fire Station Project. The building itself was designed by CDG, Inc. A Minneapolis Architectural Firm. The Construction Manager for the project was CPMI, Inc. and the project was certified LEED Silver, as requested by the City of St. Paul. The Project Manager for the city was David Nelson.
The latest advent of innovative ideas and thoughts popping up as green roofing in the minds of Engineers and professionals. The ever changing trends of roof makeover in eco-friendly zones made it a sturdy and diverse option for many homes and buildings.

Green roofs & green walls-A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.
It includes additional drainage and irrigation systems.
This presentation gives a basic information about green roofing technology with easy English in a simple way. It has been used for conducting data about a study on "Assessing the awareness about green roofing technology and the effect of lecture on it. It is with minimum words and maximum content.
In this time of rising temperatures, abundant rain and socioeconomic imbalance, this seminar will suggest that green roofs are a powerful green building Best Management Practices (BMPs).
This presentation will outline the application, feasibility, benefits and challenges of green roofs in commercial application and put several widely debated questions into perspective: modular trays v. contiguous installations, upfront cost v. long-term investment, green roof v. other options, public access v. limited access, etc. Using local, national and international examples, she will explore green roof issues re: longevity, energy savings, stormwater management, maintenance, incentives and LEED points.
The three learning objectives are a) to understand green roof ROI for commercial buildings, b) to compare stormwater strategies of green roofs v underground cisterns and porous pavers and c) to compare green roofs to a solar roof or a white reflective roof.
Green roofs are a means to lowering the overall ambient temperature, reducing longterm costs on our buildings, sequestering CO2 and producing O2, improving the quality of life in our cities and boosting our green economy. Come learn more about green roofs at this seminar on May 7th.

Analysis of Upgradation of a Convectional Building into Green BuildingIJSRD
The phenomenon of global warming or climate change has led to many environmental issues including higher atmospheric temperatures, intensive precipitation, and increased Greenhouse gaseous emission and of course increased indoor discomfort condition. Researchers worldwide collectively agreed that one way of reducing the impact of global warming is by implementing Green Roof Technology which integrates vegetation, growing medium and water proofing membrane on top of the roof surface. This study emphasized to first analysis a convectional Building than upgrade it to a Green Building by the use of some Eco- Friendly materials. In addition to this by the use of some smart electrification work we can also conserve an ample amount of energy in a Convectional Building. Than by the use of different agencies which would provide checklist for Green Building we can rate a Convectional Building which is been upgraded into a Green Building..The objectives of this research were is Reduction in the indoor temperature of the room contributes reduction in energy consumption in the building. By the use of smart electrification an ample amount of energy can also be conserved. By the use of eco- friendly materials and waste products an ample amount of money can also be saved. Although by the up gradation of convectional building the initial cost will be high because of the use of some special material such as solar panel, rain water harvesting system but their application will return 10 times of what we invested

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

The Beauty of Form and Function
Welcome to Green Roof Technology.
Spring is here and this time of year is always an especially good time
to celebrate the incredible wonders of nature’s design. We spend the
best part of our lives trying to harness nature’s beauty and utilize its
nourishing potential to better our built environments. Our commitment
to living infrastructure drives us to continue encouraging all architects,
developers, city officials, and all alike to continue integrating living
systems into their designs. The most beautiful designs in our built
environments originate from that sweet spot where form and function
meet seamlessly. In the world of living infrastructure, the beauty of form
and function resides in the systems that best mimic natural ecosystems
while carrying out their intended purpose effectively and efficiently.
In our second edition of Green Instance, we highlight products, projects,
and methodologies that exemplify this philosophy. We believe the future
of living infrastructure resides in its ability to be seamlessly integrated
with existing technologies. The combination of solar photovoltaic
elements and modern green roof technology is one such opportunity.
The ‘Sun-Root’ Living Roof System harnesses these principals and is the
newest green roof technology to reach the American shores.
Over the last five years, Green Roof Technology has had the pleasure
working with Celebrity Cruises to develop and install their award winning
Lawn Clubs. These ground-remote natural turf lawns are one-of-a-kind
and have forever transformed the landscape of seafaring habitation.
Green roofs are our passion, and no issue of Green Instance will pass
without a highlight of one of our favorite projects and a word of wisdom
about their application.
Once again thank you for your support and we look forward to continuing
our conversation.
Jörg Breuning
4. The ‘Sun Roots’ Living Roof System
A n d r e w Ya n d e r s
Heat is the enemy of energy production.
It has a negative impact on voltage,
which affects power production. When
atmospheric temperatures on a roof begin
to rise, PV elements lose their efficiency
and can shut down if temperatures rise too
high. Green roofs reduce roof top ambient
temperatures through evaporation and
evapotranspiration, dramatically increasing
PV efficiency.
BENEFITS OF THE ‘Sun-Root’ LIVING ROOF SYSTEM
• Each ‘Sun-Root’ is 7.5’ x 4’ and produces approximately 350 Watts.
• Does not penetrate roof membrane.
• First solar mounting system optimized for green roofs.
• 30° attachment angle for maximum power yield.
• PV panel inclines are adjustable for irregular roof pitch (2-5%).
• Compatible with most photovoltaic panels.
• Uses high-quality recycled HDPE with UV inhibitors for durability and extended life.
• Much lower environmental impact comparing to metal racking systems.
• Rigid ‘root’ design for maximum strength.
• Light-weight and easy to install.

6. GREEN WALLS
Climbing in All Directions
Kat Harrold
Where square footage is at a premium the
demand for green space has become one
of the hottest commodities. In a high rise
apartment building one might consider the
options quite scarce. Try thinking outside
the box, literally, and imagine all the vertical
space available. Where horizontal space is
limited, vertical gardens offer a green oasis
in a concrete jungle.
With the right plant selection outdoor green
walls make wonderful neighbors. A green
wall composed of hardy vines can provide
seasonal interest with an array of colorful
leaves and fragrant blossoms. Plant selection
can also attract birds and pollinating insects.
In spite of their good looks, climbing green
walls can be low maintenance requiring only
occasional pruning and irrigation. Steel
cables and wire-mesh grids can be used to
support and train climbing vegetation.
Green walls can play an important role in
energy savings. By shading the building
during the summer and providing insulation
in the winter, green walls reduce seasonal
stresses of heating and cooling. The ideal
location for a green wall to reduce summer
cooling costs is the south facing side of the
building. The southern exposure receives
the most sun light which can also be very
beneficial to the vines.

8. AN A-LIST EVENT
Celebrity Cruises’ The Lawn Club
Kat Harrold
Over the last three years, Celebrity Cruises
has introduced a whole new class of ships
to its fleet. Characterized by its chic and
elegant design, the Solstice Class is also
the world’s most environmentally friendly
cruise ship line.
In 2008, Green Roof
Technology was commissioned to design
and manage the installation of the world’s
first seafaring turf lawn. The Lawn Club has
become synonymous with the level of luxury
Celebrity Cruises offers to its passengers.
The wonderful reception of the Celebrity
Solstice Lawn Club has led to three more
Solstice Class ships equipped with their own
Lawn Clubs.
To meet the ship’s design challenge, Green
Roof Technology utilized modern green roof
technology to successfully reduce the profile
of the vegetation support system by several
inches in order to meet center-of-gravity
weight restrictions. If it were not for the
engineering ingenuity of the firm, The Lawn
Club would not have been realized. The
beauty of the lawn is derived from its form.
The application of good engineering has led
to a beautiful product.
Typically lawn systems supporting lush turf
grass require a soil depth of at least twelve
inches. In order to meet weight restrictions,
a 5 inch modified green roof system with
subsurface irrigation was designed.
A
surface irrigation system is used to flush
excess salts from the lawn. All runoff from
the lawn is collected and treated on the ship.
Green Roof Technology will be embarking
again to northern Germany in the fall to
manage the installation of another Lawn
Club.

Reaches Tenure
Kat Harrold
For some, green roofs may seem a novel
addition to a green minded institution but
to Swarthmore College it was an essential
and strategic move. When the college
needed to add a dormitory to accommodate
its growing student body, there were
concerns about the increased run off from
the new construction. Green roofs offered
a solution that minimized the building foot
print making construction of the new dorm
possible.
The green roof was spear headed by a few
brave faculty, dedicated alumni and students,
and Green Roof Technology. To stay on
budget the school chose to invest in a green
roof instead of the costly LEED certificate
while still building to LEED standards. This
dorm was recognized in 2010 with the
American Institute of Architects Housing
Award.

The 8,600 sf green roof is the home to many
plant species including sedum album murale,
sedum spurieum roseum, delosperma
nubigerum, and some indigenous plantings.
The green roof also features a raised planting
bed for experimental vegetation such as
cacti.
The profile of the green roof is a shallow
extensive system and has a total profile of
3.5 inches with the growing media depth
composed of 2 inches. While Swarthmore
may have a reputation for having the
best maintained green roofs in the area,
the maintenance required on the roof is
blissfully minimal. To maintain its pristine
state Gardener Lars Rasmussen weeds
occasionally as needed and irrigates only
when drought conditions exceed two
weeks. The roof is minimally fertilized and
occasionally cutting back of the overly
aggressive plants takes place to encourage
more diversity on the roof.
Since its installation the green roof has
reduced run off, air pollution, and saved
energy on the top floor of the building by
as much as 25%. While the green roof is
not available for students to congregate it
is open for guided tours and classes and is
visible to all from the third floor.

14. GREEN ROOF IRRIGATION
Environmentally Questionable and
Expensive – Why so Common then?
A n d r e w Ya n d e r s
Here at Green Roof Technology we are
often confronted with a perplexing industry
occurrence. Frequently we visit extensive
green roof sites or monitor extensive green
roof projects that have installed an irrigation
system. It is difficult to justify the necessity
of an irrigation system for extensive green
roofs. Sedums, other low growing succulent
species, many grasses, and herbaceous
plants require no irrigation. The proper
selection of plant species is crucial and
species not suited for extensive green roof
purposes should not be used. An irrigation
system wastes potable water on plants that
do not need it.
This excess water only serves to promote
the growth of unwanted plants from foreign
origins.
Four to five inch extensive green roof
systems are well suited to most regions and
do not require irrigation. (Depending on
when the extensive green roof is installed,
a temporary irrigation program may be
necessary during the establishment phase.)
Weight-saving systems less than 4 inches
are often designed with an irrigation system
to compensate for their inability to retain
sufficient water during periods of drought.
If the purpose of an extensive green roof
is to retain stormwater, then why design a
system that does not retain enough water
to moderate periods without precipitation
and requires the use of additional potable
water? It is again difficult to justify the need
for an irrigation system on extensive green
roofs.
Green Roof Technology has recommended
that local governments establish a clear
consumer-oriented guideline for the bestpractice in extensive green roof construction
in their communities. This document would
clear-up any misunderstandings among
potential green roof investors and serve well
to educate the wider public on the functions
of the various layers involved in green roof
systems.

appeared in 1982 as the “Principles of
Green Roofing” and since 1992 has been
reworked many times as “Guideline for the
Planning, Construction and Maintenance of
Green Roofing – Green Roofing Guideline.”
It is recognized as the benchmark set of
regulations for green roofing in Germany.
The FLL Roof Greening Guideline is also
widely accepted abroad and serves in
some neighboring countries as the basis
for developing their own regulations.
Our summary covers the 2008 edition of the
FLL Green Roofing Guideline. The preface
to the FLL guideline clearly states the
importance and relevancy of the Guideline
and the constant diligence taken to adapt
and outline the newest developments in
the green roofing industry. The Guideline is
the result of unpaid technical and scientific
cooperative work and is intended to be a
recognized code of practice or state-ofthe-art; it is a basic tool for the planning,
construction and maintenance of reliable
and high quality performing green roofs.
The Guideline also includes transparent,
consumer oriented testing methods for
the investigation of vegetation, substrates
and aggregate drainage materials and the
investigation of resistance to root penetration
of roof membranes and protective layers.
Three sections of this paper provide a brief
summary of the three major components
of The Green Roofing Guideline: Planning,
Execution, and Maintenance. It is important
to note that the Guideline requires a
fundamental background in horticultural
science and engineering principals. The
Guideline is not an IKEA step-by-step
construction manual designed to enable any
Do-It-Yourself project.

GREEN ROOF FORENSICS
Lancaster School District Calls In a Green Roof Doctor
B y A n d r e w Ya n d e r s
During the Fall of 2011, the School District of Lancaster and LIVE Green Lancaster requested Green Roof Technology
to tour and evaluate three green roofs in the district. The general diagnosis of the health of the green roofs was
poor. The obvious neglect of maintenance duties, coupled with a few key structural deficiencies, directly led to
the deterioration of ecosystem.
One of the most prevalent problems was the lack of weeding, which resulted in a siege on the roof by unwanted
plants. Tall weeds reached high above the sedums blocking out the sunlight and stealing water. Extensive green
roofs require a low amount of maintenance over the course of their lifespan, but do require diligent, sometimes
frequent, maintenance during their 2 – 3 year establishment phase. A coordinated maintenance program between
a maintenance team and a green roof professional is a must. Professional oversight should be present to monitor
progress and actively evaluate the health of the green roof ecosystem.
While mulching may work for ground applications, it is a death sentence to a green roof. Mulching around a
drain inlet, instead of providing a vegetation-free zone, promotes unwanted plant growth in and around the
drain. The combined effect of unwanted plant growth and accumulation of organic matter around the drain will
cause clogs and blockages. Drains must be covered with inspection boxes, surrounded by eighteen inches of
vegetation-free zone, and routinely inspected as part of the maintenance program. In this case, the drainage
area must be cleaned and rebuilt by a green roof professional in order to mitigate potential structural issues and
begin the journey back to full health.
