Case Study Briefs
Advocate Lutheran General Hospital Patient Tower
Park Ridge, Illinois
“Views of the hospital’s intensive green roof helped reduced stress and make the hospital stay easier for half of cancer patients surveyed. This demonstrates how green roofs and other living infrastructure can help in the healing and coping process.”
Underwood Family Sonoran Landscape Laboratory
“The southern exposure features a green façade of native vines, which shade and cool the building. This type of green wall offers a fairly low-cost way to beautify, screen, and add function to what would otherwise be disregarded space.”
Gary Comer Youth Center
“This intensive green roof is a working garden that produces over 1000 lbs of organic food annually and functions as an outdoor classroom. The design showcases how green roofs can be integrated with other sustainable systems like light wells and passive climate control.”
Klyde Warren Park
“Green roof systems can be used on a wide range of scales, from a residential roof to a multi-block, at-grade structure over parking or transportation infrastructure. This 5-acre green roof acts as a bridge, tunnel, and park all in one, transforming this part of Dallas.”
Fast Fact Library
The combination of green roofs and green walls can lower ambient temperatures in typical “urban canyon”-like streets, achieving up to a 12.8˚C (23˚F) ambient temperature difference in an arid climate, and 8.4˚C (15.1˚F) in a humid climate. This combination had the greatest effect compared to no vegetation, green roofs only, and green walls (walls covered in vegetation, such as climbing vines) only. Green roofs alone had the second greatest ambient temperature effect, likely due to roofs’ higher exposure to sunlight.
“This study illustrates how various forms of living architecture can be used together to increase impact.”
A green roof test plot at the University of Georgia retained 88% of precipitation for small storms (<2.54 cm), 48% for larger storms (>7.62 cm), and delayed the peak flow by an average of 18 minutes for 31 rain events between Nov 2003 and Nov 2004.
“This is one of many test
plots and actual green roof studies that show how green roofs can significantly reduce the volume of stormwater runoff and delay peak flows.”
Green Roof Energy Calculator (v 2.0)
Green Roofs for Healthy Cities, Portland State University, University of Toronto
“Green Roofs for Healthy Cities (GRHC) collaborated with researchers at Portland State University and the University of Toronto to develop this free, easy-to-use tool. For GRHC members, we also developed the GreenSave Calculator, which allows users to compare the life cycle costs and benefits of up to three roofing designs.”
This fall, LAF is rolling out 20 new case studies that showcase the environmental, economic, and social benefits of high-performing landscapes. The case studies are part of LAF’s award-winning Landscape Performance Series, an online, interactive set of resources to help you quantify benefits, show value, and make the case for sustainable landscape solutions. By year-end, the searchable database will contain over 100 Case Study Briefs.
From the Atlanta Beltline to exemplar public high schools to the Visitors Center at Thomas Jefferson’s Monticello, the new case studies represent a range of locations, scales, and project types. Documented landscape performance benefits include:
- Influenced the housing choice of 76% of 51 survey respondents who live within one mile of the park. (Renaissance Park, Chattanooga, TN)
- Reduces hardscape surface temperatures by 30-45°F and maintains playground surface temperatures under 82°F. (George “Doc” Cavalliere Park, Scottsdale, AZ)
- Promotes physical activity with 70% of survey respondents saying they exercise more since the opening of the Eastside Trail. (Atlanta BeltLine Eastside Trail, Atlanta, GA)
- Provides educational opportunities for an estimated 50,000 visitors per year. 68% of 71 survey respondents achieved the learning objectives, answering 7 out of 9 questions correctly. (Brian C. Nevin Welcome Center, Cornell Plantation, Ithaca, NY)
- Contributed to an 85% increase in the values of properties that were located within a half-block of the streetscape. (1100 Block of Lincoln Road Mall, Miami Beach, FL)
These exemplary projects were documented through LAF’s 2014 Case Study Investigation (CSI) program, a unique research collaboration that matched 7 LAF-funded faculty/student research teams with practitioners from 15 participating design firms. The teams worked together to develop methods to quantify performance benefits and produce the Case Study Briefs. The next CSI program will run March – August 2015 with applications available starting in October.
To bring the concept of landscape performance to new strategic audiences, promote next-generation infrastructure, and enhance the experience for the 60,000+ unique users, LAF is developing a new website to house its Landscape Performance Series (LPS) and related resources.
The new website will feature “Collections”, themed groups of LPS content curated by LAF and leading thinkers, as a new way to organize and share content. When the site goes live in November, the Collections will be fully searchable and follow the design at right. But in the meantime, we’ve put some together right here in our blog to give you a preview of this exciting new content.
So…. <drumroll>, here are our first Collections. We’ll update this list as we put together more over the coming months.
- The Case for Street Trees
Need to advocate for more street trees, better design tree space design, or preservation of existing trees? Here are some useful precedents and research.
- Small But Mighty
It doesn’t necessarily take a lot of space to have a big impact. Here we showcase some of the smallest projects in the LPS along with Fast Facts on the benefits of even modest amounts of green.
If you have ideas for themes you’d like to see addressed in the Collections, please send them to firstname.lastname@example.org. And be sure to mark your calendars for when the new Landscape Performance Series is slated to launch in November!

Case Study Briefs
Central Wharf Plaza
“At just 13,100 sf, this small plaza connects Boston’s Rose Kennedy Greenway with the Inner Harbor waterfront, serving some 280 pedestrians per hour. It also lowers ground-level temperatures by 10.4°F with tree canopy cover that shades 94% of the site. Pretty cool.”
ASLA Headquarters Green Roof
”The unique ‘waves’ aren’t the only thing that make this green roof seem bigger than its 3,000 sf. It is the subject of ongoing research, has hosted over 5,000 visitors, and has an extensive multimedia educational component that receives 35,000 annual pageviews.
Elmer Avenue Neighborhood Retrofit
Los Angeles, California
”This retrofit demonstrates that transportation infrastructure improvements can be combined with stormwater management to prevent flooding, improve walkability, and beautify the street. The street and residential properties along this one city block capture and filter runoff from a 40-acre area.”
Erie Street Plaza
“The City had lofty ambitions for this 0.25-acre former parking lot: create a significant public place that would become a key component of Milwaukee’s waterfront and new development in the Third Ward. The simple, inventive, and open-ended design does just that.”
Fast Fact Library
In a study of a Chicago public housing development, buildings with high levels of trees and greenery had 48% fewer property crimes and 56% fewer violent crimes than identical apartments surrounded by barren land. The greener the surroundings, the fewer the number of crimes that occurred, and even modest amounts of greenery were associated with lower crime rates.
“The greenery in this study was trees and grass, and the research suggests the exciting possibility that small-scale tree planting and beautification efforts in barren inner-city neighborhoods could help to create safer communities.”
An analysis of the impact of greening 4,436 vacant lots in Philadelphia found that greening was associated with residents’ reporting significantly less stress and more exercise in select sections of the city.
“The vacant lots that were greened averaged just 1,800 sf in size and yet correlated with improved health outcomes.”
Research in Tel Aviv determined that the presence of trees cooled the air from between .5°F on a heavily trafficked street to 2°F in a small (.37 acre) garden. The study also found that the cooling effects could be felt up to 330 feet from the site.
“The cooling effect of small groups of trees was noticeable not only within the wooded areas but also in their treeless surroundings.”
