LEED Thermal Comfort Survey

Leadership in Energy and Environmental Design, or LEED, as it’s commonly known, is a
points-based third party verified green building certification process created and managed by
the US Green Building Council (USGBC). The certification process awards points for pursuing
sustainability measures in categories including sustainable sites, water efficiency, energy and
atmosphere, materials and resources, indoor environmental quality, as well as innovation in
design.

UW-L has pursued and earned LEED certification in the following facilities.

Centennial Hall – Gold Certification
• Academic building at approximately 195,000 gross square foot
• Substantially completed/occupied in August 2011

Eagle Hall – Gold Certification
• Residence Hall serving about 500 students with space for the Office of Residence Life
• Approximately 228,000 gross square foot
• Substantially completed/occupied in August 2011

UW-L received an Innovation in Design point in these facilities for recognizing the importance
of completing thermal comfort surveys. Thermal comfort can be defined in many ways. ANSI/
ASHRAE Standard 55 defines thermal comfort as: “the condition of mind that expresses
satisfaction with the thermal environment”. ISO 7730 defines thermal comfort as: "That
condition of mind which expresses satisfaction with the thermal environment".

In the end, Facilities Planning and Management (FP&M) operates under the principle that two of
the most important parameters that affect human performance and health in a facility are thermal
comfort (temperature, humidity and air flow) and indoor air quality (ventilation). To address
these factors, FP&M will request occupants in facilities pursuing a LEED point for thermal
comfort to complete an anonymous thermal comfort survey. The survey will be completed twice
per year, likely in February and September.

In accordance with the LEED EQ credit 7.2 requirements, FP&M staff will take action to
remedy thermal comfort settings when 20% or more of facility occupants are not satisfied with
thermal comfort. Corrective actions may include, but are not limited to adjusting system controls
(temperature set points, schedules and operating modes), air flow adjustments and solar controls.
