leading edge projects such as the Transbay Transit Center in San Francisco, California.
Integrated Water Management for Buildings and Sites
Jeffrey L. Bruce, President, GRP, FASLA, LEED, ASIC, President, Jeffrey L. Bruce & Company, Chair, Green
Roofs for Healthy Cities
Developed jointly by GRHC and American Society of Irrigation Consultants (ASIC) committee members, this course provides technical
and economic information on the design and performance of a fully integrated site and building water management system based on
the “Net Zero Water” concept. This approach promises to significantly reduce the consumption of potable water in buildings, reduce
discharge to municipal waste water systems, and save on municipal energy by reducing the amount of potable water treated at
municipal facilities. The recognition of the connection between water management and energy conservation is emerging as a new
opportunity in integrated management systems. Key concepts and terminology are illustrated by case studies and demonstration
projects which identify issues and opportunities associated with costs and benefits, design and engineering practices, installation and
maintenance requirements, and efficiency and performance of a fully functional integrated site and building water management
system based on the “Net Zero Water” concept.

Integrated Water Management for Sites and Buildings 201: Case
Studies in Performance
Jeffrey L. Bruce, President, GRP, FASLA, LEED, ASIC, President, Jeffrey L. Bruce &
Company, Chair, Green Roofs for Healthy Cities
LAUNCH
This new course is the second part of Integrated Site and Water Management education series, the first course provided in the morning. Achieving net-zero water
utilizes the concepts of the using and reusing water multiple times on site and to provide to the greatest degree possible a closed loop of water. There are seven
steps associated with this integrated water cycle. While this concept may not be achievable in certain projects, incorporation of its principals can lead to reduction of
domestic water and sewer dependency. This course will focus on a number of case studies from different regions and explore in detail the design, installation,
maintenance, policy and economic realities of these net zero water systems. Jeffrey L. Bruce is an award winning designer who is pioneering new approaches to
design for net zero water. He has worked on award winning projects such as Millennium Park in Chicago, Citygarden in St. Louis, 909 Walnut Street. This course was
developed in partnership with the American Society of Irrigation Consultants with generous support for Ewing and Jeffrey L. Bruce & Company.
Ecological Design Workshop
Dr. Brad Bass, University of Toronto/ Environment Canada
With each passing year, we come to understand that there are enormous possibilities to design and maintain green roofs and walls in a manner that supports
biodiversity. With the recent collapse of bee populations, we are slowly beginning to realize that the preservation of biodiversity is inextricably linked to our species
self-preservation. Ecological Design is a specialized course that teaches participants how they can achieve maximum biodiversity benefits from their green roof
project and covers such topics as how to design a green roof to support native flora and fauna and provides case studies that illustrate these principles.
Dr. Brad Bass has been a leading researcher of green roofs and walls for more than a decade and he recently developed a Biodiversity Research Protocol to support
biodiversity research with colleagues from around the world.

2D – Its’ Not Easy Being a Green Wall – Invaluable Lessons from the Field
1. Living Walls: Integration of Water Re-Use Systems
Aesthetics are often the primary motivation for inclusion of living walls in interior environments but more emphasis is now placed on the functional attributes of this
form of living architecture. As buildings move towards net zero waste and innovative water re-use systems, designers must focus on the conservation of water via
sustainable options for landscape irrigation. Vertical landscapes and water containment mechanisms can assimilate to offer creative solutions for water reuse
applications; ultimately creating the option for a more sustainable living system.

3. A Review of Multiple Designs for Urban Food Production on Green Roofs and Walls Which Incorporates Water Purification and
Biofuels
Concerns for urban food security are growing as recent severe weather events, earthquakes and conflicts have show that cities can be completely isolated. Most will
run out of food in three days. The most efficient way of producing food in urban areas is to utilize space at grade. However, this space is often not available or in
higher-density urban areas, non-existent. Roofs provide opportunities for food production, but not all crops are amenable to every roof and depth of media,
accessibility to people and other objectives for the green roof will limit food production opportunities. One underutilized space for growing vegetation in urban
environments is the wall. There are several available means of producing food on wall and opportunities for several types of crops. Robert Cameron took this a step
further and integrated a vertical food production system with biofiltration of water. Cameron's system can work with grey water or black water. With black water,
there are opportunities to also create biofuel that could be used for heat or small amounts of electricity. This integrated system could be modified further for raising
fish, rice and vegetables. A breathing wall could be modified for some food production, particularly fish. These various systems, along with some test results are
presented with some designs for integration at the home and at the neigbourhood scale.

The SAP Expansion building on the Newtown Square Campus- Brian Barrett, Project Manager Global Facility Management, SAP America, Inc.; Nate Johnson, Head of
Project Delivery, Roofmeadow
This tour of a LEED Platinum project features green roof areas on three roof levels including extensive and intensive profiles. Three types of irrigation are in use at
SAP and the reasons for using one type over another will be addressed during the tour. The intensive areas are irrigated with rainwater that is harvested on site and
stored in a 50,000-gallon cistern. The integration of the rainwater harvesting system and the green roof represent an ideal irrigation method, and the need to use
potable water to sustain the vegetation is minimized. The green roof profiles support a wide variety of plants suitable to this engineered environment where
stormwater is utilized as an asset rather than shuttled away to a storm drain. The green roof areas at SAP serve multiple functions. The intensive green roof areas
serve as amenities while the extensive areas function as green infrastructure. The 4th floor roof serves as an amenity to a large number of employees and campus
visitors. In addition to the 2,000 employees working at the facility, more than 3,000 people visit the facility each year, and many of them are encouraged to take
advantage of the roof-top landscape— and on this tour, you will too!

This tour will take us to two internationally acclaimed educational/horticultural institutions to visit their state-of-the-art green roofs and walls. Our first stop will
be to the Scott Arboretum of Swarthmore College where we will tour four buildings with green roofs--two of them on student residence halls. The first green roof was
installed in 2002 and the most recent was installed this past year on the LEED Gold Wister Center for the Scott Arboretum by the gardening staff at the College. The
roofs vary from extensive to semi-intensive and the majority of the roofs were planted with sedum cuttings. Each year over 700 people visit the green roofs on
regularly scheduled tours led by the gardening staff.
We will then travel to Longwood Gardens to see the largest green wall in North America. Opened in October 2010, the East Plaza Green Wall features a GSky panel
wall system spanning over 4,000 square feet with over 25 different types of interior plants. The design is deeply rooted in a tradition of engineering excellence and
horticultural innovation, while also embracing a contemporary aesthetic that captures the very essence of Longwood Gardens. Guests will be treated to a
presentation while enjoying a boxed lunch, followed by a guided tour of the wall. There will be time afterward to tour the world-renowned holiday display in the
conservatories and grounds on your own until we leave just as the Christmas lights come on.
