Green Rating System for Public Works

By -

From WPA to the U.S. Interstate Highway system, to ARRA and local bond initiatives, projects for public works and infrastructure keep cities and the economy humming along, but can they do even more.  Can economic, environmental and social synergies contribute even more to our communities?  The developers of Envision (TM) say "Yes!"

Envision is a "green" sustainability rating system for infrastructure projects.  Introduced in 2012, it's the result of a joint collaboration between the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design and the Institute for Sustainable Infrastructure (ISI).

Public works and infrastructure projects can now receive the recognition for sustainable approaches that their architectural and development projects have received through LEED, Living Building Challenge, Green Globes and similar third-party rating systems.

Similar to LEED, the system has 60 sustainability criteria, called credits, divided into five sections: Quality of Life, Leadership, Resource Allocation, Natural World, and Climate and Risk.  Tools include checklists and a planning guide.  The Envision process helps to identify community goals and outcome-based objectives, leverage collaboration, evaluate life cycle costs and achieve recognition for successful projects.  More detail about the Envision system can be found on the ISI website.

Projects can include stormwater management, aspects of master planning infrastructure, and roads.  Given the upcoming infrastructure development for communications and transportation, the systems' birth is timely.  According to a recent GreenBiz article by Anna Clark, "estimates for modernization of transportation, energy, and water infrastructure run as high as $3.6 trillion needed by 2020."

An example of an a certified project is the South Los Angeles Wetland Park.  Transformed from a former bus and rail yard, this park received a  Platinum award for credit areas of Leadership, Quality of Life, Resource Allocation, and Natural World.  Specific achievements include creation of green space, stormwater management, and restoration of habitat supporting biodiversity.  Like most Envision-qualified projects, the park is an outgrowth of partnership between public works departments, private engineering and public funding.  The partners for this project include the
 City of Los Angeles Department of Public Works Bureau of Engineering and Psomas, a private consulting company who provided planning, design, and management services.  According the the Envision website, funding was provided through "Proposition O, a program supported by a series of general obligation bonds valued at $500 million, whose projects were conceived to protect public health by removing pollution from the City's watercourses, beaches, and the ocean to meet Federal Clean Water Act requirements."

Sean P. Vargas, Envision Verifier and  Psomas Principal, Director of Sustainability, described "The South L.A. Wetland Park [as] a good example of an integrated engineering solution that successfully built consensus, captured and improved local urban runoff, and created a new neighborhood-revitalizing amenity. It represents what is possible when an owner and an engineer collaborate and redefine the paradigm of multi-benefit projects."

Reflecting on a Decade of Dedication - Melina Clark!

by: Melina Clark "These past ten years at Sparkflight Studios (SFS) flew by.  SFS was my first architectural job, and I could not have asked for a more fantastic mentor than Anne. I have learned so much from her, including honesty, integrity, and hard work. Architecture is not an easy career, but it is worth it when you have meaningful projects.     My favorite project to date is the Southern Nevada Regional Housing Authority (SNRHA) Wardelle Street Townhouse project. I genuinely enjoy working on affordable housing. There is a significant need for affordable housing in this Valley and across the United States. Wardelle Street Townhouses provide 57 units for families or individuals in need. These units have market-rate amenities, which help the tenants feel pride and care for their homes.     Wardelle Street Townhouses was my first ground-up project, which is incredibly exciting as a designer. Having an opportunity to help shape a piece of land that benefits the community is my rea

The Business of Architecture: Staffing, Retention & Recruitment left to right: Mark Johnson, AIA; Anne Johnson, AIA; Greg Erny, FAIA; Angela Bigotti, AIA Last month, AIA Nevada hosted the Fellows Forum (in conjunction with SFx) to discuss an important topic today - Staffing, Retention & Recruitment. The panel included long-time AIA members Mark Johnson of H+K Architects, Anne Johnson of Sparkflight Studios, and Angela Bigotti of Van Wert Bigotti Architects, as well as AIA Fellow Greg Erny of architects + LLC.  Key takeaways from the discussion included: The challenge of recruiting and growing young talent from novice to competent practitioner. How to engage and grow with emerging professionals in the office and still maintain an efficient practice. A representative from Truckee Meadows Community College joined in the discussion, and shared how they are the first community college in the nation to offer an associate degree in architecture.
