How Commercial Property Investment in Green Roofs and other Green Infrastructure Improvements Can Create Value - Janet Clements, Senior Economist, Stratus Consulting

Ms. Clements will be presenting her findings from a recent report, funded by the Natural Resources Defense Council, on the benefits that can accrue to private property owners when they implement green infrastructure (including green roofs) on their property. In many cities, private property owners can receive a stormwater fee credit for installing green infrastructure. However, even in cities with relatively high stormwater fees and available credits, the value of the credit alone often will not provide a sufficient economic incentive to motivate investment in these environmentally beneficial practices. To encourage additional implementation of green infrastructure, this report identifies and quantifies (to the extent feasible) the range of additional economic benefits that green infrastructure can bring to property owners, including owners of multifamily residential buildings. When accounting for these benefits, commercial property owners receive a much greater return on investment -- and have a much stronger business case for green infrastructure investments -- than when considering stormwater fee savings alone. Benefits evaluated include: increased rents and property values; increased retail sales; energy savings; stormwater fee credits and other financial incentives; reduced infrastructure costs; reduced costs associated with flooding; reduced water bills; increased mental health and worker productivity for office employees; and reduced crime. 

 

Acoustical Characteristics of Green Roofs and Living Walls; Effects on Indoor and Outdoor Acoustical Environments - Dr. Maureen Connelly, British Columbia Institute of Technology

Vegetative roofs are increasingly used in sustainable building construction and have the potential to improve the acoustical environments inside and outside buildings because of beneficial sound absorption and transmission-loss characteristics. A multi-tiered approach is required to address the ecological contributions of vegetated roofs and their acoustically relevant characteristics at the building and site scale. The findings from novel research projects on the acoustical characteristics of vegetative roofs are presented and propose a framework to embed the new qualitative and quantitative knowledge of vegetative roofs into the architectural design process. The capacity of vegetated roofs to increase the ecological performance of buildings and contribute in a positive manner to the urban soundscape was determined by investigating the acoustical characteristics of vegetated roofs. It was found that substrates provide significant sound absorption, and that less water content, more organic matter, and less compaction increase absorption. In addition, vegetated roofs act as a sound attenuating absorptive ground on the roof and have the potential to absorb between 20%-60% of incident sound energy. Adding a vegetated layer to a roof reduces sound transmission, with vegetated roofs having higher performance in mitigating low-frequency noise than many non-vegetated roof systems. Finally, the urban soundscape experience on the rooftop is altered by a vegetated roof; natural sounds increase and street level sounds decrease with the inclusion of plants on the roof. The research findings quantitatively define vegetated roofs as an acoustical solution for the control of noise and inform the architectural design process about the capacity of vegetated roofs to increase the sustainable and livable use of rooftops. Vegetative roofs simultaneously embrace and contribute to the contextual soundscape; ultimately, this allows designers and users to realize an increase in the aural quality of place, both inside buildings and up on the rooftops.


The Janey Apartment Ecoroofs: The Business Case - Agustin Enriquez V, AIA, LEED AP, Principal, GBD Architects Incorporated, and Kurt Lango, Principal, Lango Hansen Landscape Architecture PC

The Janey Apartments is a mixed-use, multifamily development in downtown Portland.  It consists of 50 market rate apartments averaging 570 square feet per apartment (mix of one bedrooms and studios).  Given the prime location in the heart of Portland’s very desirable Pearl District, the design team was tasked with creating a project that would set a new upper limit for rent per square foot.  During the design phase, the team made a calculated decision that typical amenities such as a fitness room, community room, or lounge would not be included.  Instead the team focused on creating a rooftop amenity space open to all residents that needed to be of a quality that would attract residents and be a deciding factor when evaluating where their next residence would be.  As such, the rooftop space included a bbq, a fire pit, ample seating, an herb garden, and a pre-grown sedum tile eco-roof.  Because the roof top amenity space has been consistently noted as a top draw during post-occupancy conversations with residents, the Ownership group has decided to include a roof top amenity space surrounded by an eco-roof on their next building even without the City of Portland Ecoroof Incentive.

Getting to the Root of Green Roof Retrofits - Ilana Judah, Director of Sustainability, FXFOWLE Architects

Incorporating a green roof on an existing building is a process that presents multiple challenges from the initial design concepts through installation and maintenance. This session will focus on the planning necessary to achieve a successful green roof project on an existing building. Issues addressed in the presentation include structural analysis, code and zoning requirements, compatibility with existing conditions, daylight, installation logistics, irrigation, and maintenance. Case studies of various scales and typologies will be presented, including the new seven-acre green roof at the recently renovated Javits Convention Center in New York City.

 

Design+Science:  Linking Green Roof Research to Practice - Jason King, Senior Landscape Architect, Herrera Consulting          

Today’s complex projects need strong connections between design interventions and scientific research to ensure successful outcomes. Nowhere is this more true than with green roof projects, where multiple components of media, plantings, drainage, and waterproofing work in tandem to provide myriad benefits such as stormwater management, thermal performance, roof longevity,  habitat provision, and more.  While this link has become more evident in recent years, we need to provide stronger ties between research & practice that will maximize performance, alleviate risk, and facilitate innovation. Specific design and maintenance decisions can be improved through on-going monitoring, research, testing and analysis.  To this end, research can be more focused through an integrated process that aims to provide actionable, evidence-based direction for designers.  This presentation will cover a range of topics including: current research and impacts on design; barriers to accessing information; and a process for integrated design thinking.  Q&A will offer a chance for discussion of these topics with the range of researchers and designers in attendance.

 

White, Black or Green: Disaggregation of Value Proposition is a Major Challenge for Green Roofs - Aditya Ranade, Lux Research

Green roofs are already a $7 billion global industry, mainly driven by the incentives from 60+ cities around the world. However, for widespread acceptance beyond these 60 cities, and increasingly even in these cities, green roofs will compete with reflective roof coatings, roof insulation, and design solutions for storm-water collection. As economic drivers overtake environmental, green roof installers must gather in-field data to quantify the benefits of storm-water volume reduction, increased roofing membrane life, and thermal insulation. In this presentation, Aditya Ranade will discuss initial attempts towards this, the resultant economic analysis and what it means for the green roofs sector going forward.

 

The Developing Problems in Multifamily Roof Design and How Ecoroofs are Part of the Solution - Shawn Sullivan, Development Manager at Winkler Development Corporation

The most expensive and frequently reoccurring capital expense for commercial building is the replacement of the roof membrane. A recent study of roof conditions on the west coast showed the Portland/Seattle area with roughly 30% of roofs tested at a moisture level of risk or failure after ten years. This means that for a large number of buildings the most expensive element impacting replacement reserves will possible fail after half the expectant life cycle. In the last three years Sullivan Architecture has collaborated with Schaber Roofing Consultants on seven different roofing projects, including; new construction and renovation, Ecoroofs, Structural Insulated Panels, concrete decks, plywood decks, and multiple membranes. Each project has been a balance to provide the best solution in the most cost effective manner. The complexity and possibilities of roof solutions is no longer something that should be resolved just by specification and price point, but instead needs to be considered starting with the initial design of the project. The goal of the workshop is to better inform all team members regarding the composite that makes a contemporary and long lasting roof system, so that when they discuss and/or consider an Ecoroof application, they better understand the dynamics, relationships, costs, and benefit by considering the cause and effect of multiple options.

  Anne Whiston Spirn, Massachusetts Institute of Technology

Anne Whiston Spirn is an award-winning author and distinguished landscape architect, photographer, teacher, and scholar. Her work is devoted to promoting life-sustaining communities: places that are functional, sustainable, meaningful, and artful, places that help people feel and understand the relationship of the natural and built worlds.

Spirn, a professor of landscape architecture and planning at the Massachusetts Institute of Technology, is the author of three books: The Granite Garden; The Language of Landscape; and Daring to Look. The Granite Garden: Urban Nature and Human Design (1984) describes nature in cities and what the city could be like if designed in concert with natural processes, rather than in ignorance of them or in outright opposition. The Language of Landscape (1998), extends these ideas; it argues that landscape is a form of language with its own grammar and metaphors, and that we endanger ourselves by failing to learn and use this language. Daring to Look (2008) presents photographs and reports from the field by the great photographer Dorothea Lange in 1939 and reflects on how the dynamics she saw and recorded in the Great Depression are still shaping American lives and landscapes. Spirn has also written a series of essays that explore how ideas of nature and community have influenced great planners and designers such as Frederick Law Olmsted, Frank Lloyd Wright, and Ian McHarg. Since 1987, Spirn has directed the West Philadelphia Landscape Project, an action research program integrating research, teaching and community service, which was cited as a Model of Best Practice at a 1999 White House summit for leading scholars and artists in public life. Spirn’s book-in-progress, Top-Down/Bottom-Up: Rebuilding the Landscape of Community, describes this research-in-action and its lessons for building safer, healthier, and more equitable and sustainable communities.

In the 1970s, Spirn worked as a landscape architect and planner in professional practice at Wallace McHarg Roberts and Todd in Philadelphia on projects ranging from plans for an entire region to a single city to designs for parks. Several of these won awards, and some, like Woodlands, Texas and Sanibel, Florida, are considered landmarks. Spirn was on the faculty of Harvard University from 1979 to 1986, then moved to the University of Pennsylvania, where she succeeded Ian McHarg as chairman of the Department of Landscape Architecture and Regional Planning. She has been at MIT since 2000. In addition to teaching, Spirn lectures widely in the US and abroad at colleges and universities, as a keynote speaker at conferences, and for organizations like the League of Women Voters.

Spirn was born in Waterbury, Connecticut, grew up in Cincinnati, Ohio, and lived in Denmark for a year as an American Field Service exchange student. She graduated with honors from Radcliffe College, where she studied art history, and received her master’s degree in landscape architecture from the University of Pennsylvania. She has received numerous fellowships and awards including the Guggenheim Fellowship and the President’s Award of Excellence from the American Society of Landscape Architects. Her work as a whole has been honored on two occasions. In 2002, she was one of two finalists for the National Design Award in environmental design. In 2001, she received the International Cosmos Prize for “contributions to the harmonious coexistence of nature and mankind.”

Spirn has one adult son. She and her husband live near Boston.
