Improving the Occupant Experience in LEED Buildings: It’s Time for Ergonomics
In Canada and the United States, individuals spend more than 90 percent of their time indoors and are becoming increasingly more aware of their environment and how it impacts their health (Hancock, 2002). Evidence suggests that where we live and work can be clearly linked to our overall health (Srinivasan, O'Fallon & Dearry, 2003). With this growing awareness and concern, a demand has risen to evaluate buildings independently for their environmental and health impacts (CaGBC, 2010).
Over a decade ago, a coalition of building industry leaders in the U.S. created building design and construction guidelines for the environmental assessment of buildings (Lee & Guerin, 2009). The Leadership in Energy and Environmental Design (LEED) a green building rating system, was then formed (CaGBC, 2010). The LEED Building Rating System is a voluntary, consensus-based standard that evaluates the environmental performance of a building over its entire life cycle (CaGBC, 2010). The primary goal of LEED is to promote building practices that are environmentally responsible, profitable, and healthy for its building occupants. To date, over 11,000 projects have been certified in the U.S. and approximately 600 in Canada (CaGBC, 2012; USGBC, 2012).
To date, evidence suggests that much attention has been given to the environmental impact of LEED buildings, but limited attention has focused on the health impacts for occupants. For example, in a federal study commission in the U.S. examining funding during the period of 2002-2005, it was determined that energy related research received 72% of available funding, while topics focusing on indoor environmental quality only received 2% funding (Baum, 2007). Recently, this was also highlighted in a report completed by the Institute of Medicine, citing the need for increased attention to the impact of green buildings on the health of occupants, since people spend the majority of their time indoors (Institute of Medicine, 2011). A number of studies have highlighted that human responses comprise the majority of the expenses in an office building (Romm, 1994).
LEED certification requirements are not static and currently, LEED is in the final phase of its third revision - due out later this year. As part of the generation of the LEED 2012 rating systems, the USGBC has highlighted the need to address occupant experience in LEED rating systems, identifying it as one of its three priorities to be addressed in the revision (USGBC, 2012). To enhance occupant experience in the design and operation of LEED buildings, utilizing ergonomics early in a proactive fashion ensures occupant needs are identified and addressed effectively.
Recently, a pilot credit has been added by the USBGC to its Pilot Credit Library. Pilot Credit 44 for an Ergonomics Strategy is currently being pilot tested. Under the Innovation in Design category, a project can apply for a credit for an ergonomics strategy. The pilot credit applies to the following LEED project types:
- New Construction
- Retail – New Construction
- Commercial Interiors
- Retail – Commercial Interiors
- Existing Building: Operations & Maintenance
The intent of the pilot credit is to “promote healthy, comfortable and productive work by designing the workplace to accommodate its users (USGBC, 2012, p.1)”. As a pilot credit, stakeholders have the opportunity to engage in the development of a credit and the LEED rating system. This allows the USGBC to test and refine the credit through LEED project evaluations (USGBC, 2012). Since the credit is currently a pilot credit, projects wishing to apply for the credit must register with the Pilot Credit Library – http://www.usgbc.org/leed/pilot/PilotLibraryProjectReg.aspx. LEED projects participating in the piloting of the credit can receive one point under the Innovation in Design Credit. The primary components of the credit require:
- Identification of tasks and building functions that would benefit from the application of ergonomics in the selection of furniture, equipment and provision of education,
- Prior to designing the interior, consult with and analyze occupant needs (user characteristics, tasks performed and equipment and materials used) - addressing lighting, thermal comfort, office layout, individual work station design, furnishing and equipment,
- Demonstrate that key ergonomic principles have been incorporated into the interior design facilitating occupant well-being, and
- Provide ergonomics education and training to all users upon installation.
This is an exciting time for the field of ergonomics. Outside agencies are acknowledging the value of ergonomics in the design and operation of green buildings/projects by recognizing it as a credit. The link is being made between ergonomics and sustainability. For more information on the credit, refer to Pilot Credit 44LEED Pilot Credit Library http://www.usgbc.org/ShowFile.aspx?DocumentID=10097
