Last week at the annual Council of Educators in Landscape Architecture (CELA) Conference in Austin, Texas, LAF presented new insights on landscape performance gleaned from the Landscape Performance Series (LPS) and the Case Studies Investigation (CSI) program.
Executive Director Barbara Deutsch and Programs Manager Linda Ashby participated in four sessions, presenting alongside past CSI Research Fellows, student Research Assistants, and other colleagues. LAF’s sessions at CELA included panels on evaluating landscape performance for environmental, social, and economic benefits, as well as a panel on applying science to design for and evaluate performance. These sessions offered participants an introduction to both the LPS and CSI research programs, and a critical look at the research methods employed.
The first session introduced CSI and the concept of quantifying performance benefits. The session offered the opportunity for audience members to discuss the program’s approach, as well as participants’ strategies for quantifying specific social, environmental and economic benefits. Participants introduced their own experiences: for example, Jessica Canfield (Kansas State University) presented her CSI research evaluating the Frontier Project, a demonstration project in California which seeks to encourage visitors to incorporate energy efficient and water-wise practices in their homes. Canfield’s team studied the site’s rainwater infiltration, irrigation water needs and projected carbon emissions and analyzed attendance records and surveys with on-site employees. Canfield and others, including Mark Storie (University of Maryland), also discussed their strategies for obtaining data and the varying levels of data availability at different types of sites.
Many of landscape performance sessions focused on research methods. At the panel on environmental performance, Barry Lehrman (Cal Poly Pomona) described his experience “measuring the (not so) unmeasurable,” introducing the tools used by his CSI research team, including affordable temperature gauges and water quality meters. In response to presentations by Lehrman and his fellow panelists, moderator Kristina Hill, PhD (UC Berkeley) described the recent context for measuring landscape performance, noting that until recently many metrics were discipline-specific, leading to “very little synthesis.” She challenged those attending the session to “be critical in our reflection on these metrics” so researchers could continue to advance their strategies and obtain a holistic understanding of the benefits of landscape design.
Participants in CELA sessions also discussed means of communicating the concept of landscape performance benefits to policy makers, other design professionals, and the general public. Presenting in a panel on economic benefits, Dennis Jerke (Texas A&M) noted that “we have to be good communicators… and explain what the metrics mean and how the value has been generated.” Similarly, Mary Myers, PhD (Temple University) noted that comparing a project’s performance to its initial goals can be a helpful strategy for engaging clients and others in the discussion. To Myers, “the metrics should measure the extent to which goals were met” whether in terms of stormwater mitigation, improved biodiversity, economic development or public access.
LAF looks forward to continuing the dialogue started at CELA Conference and bringing the new insights to the 2013 CSI program and its participants.
