49ers’ New Levi's Stadium: A Behind-the-Scenes Look at
This Impressive Green Stadium
Speaker: Heath Blount, Brightworks
All sports fans are excited about the newly constructed Levi's
Stadium in Santa Clara, California, the new home of the San Francisco
49ers. But facilities engineers will be especially interested to hear
about the many green features of the impressive new stadium. This
presentation will provide a behind-the-scenes look at what makes
Levi’s Stadium an important green stadium. Topics will include the
stadium's 1,162 solar panels; the high-efficiency, water-conserving
toilets and sinks; the vegetative roof utilizing native plants; the
use of recycled construction materials; the installation of
high-efficiency LED lighting; and the electric vehicle charging
stations. The speaker also will discuss that the stadium is working
toward LEED for New Construction Gold certification, and may become
the first NFL stadium to achieve that distinction.

IEEE Guide for Grounding System Characterization (Std.
81
Speaker: Dr. Ahmad Shahsiah, Exponent
Dangerous levels of voltage can be developed at the equipment
enclosures and other accessible parts of an electrical system in the
event of a major short-circuit fault; these are known as touch
potentials. When this type of voltage develops on the ground as a
result of the flow of the fault current through the earth, it is
known as the step potential. An effective grounding system can reduce
the touch and step potentials and provide safety for the personnel
during electrical fault conditions.
IEEE Std. 81 defines test methods and techniques used to measure
electrical characteristics of the grounding system including
measurement of the earth resistivity. Characterization of the
grounding system is essential in estimation of the touch and step
potentials; and thereby, are necessary during the safety evaluation
stages of an existing industrial power system. This presentation is a
review of the IEEE standard 81 and its application in safety
evaluation of the grounding systems including estimation of the
levels of the touch and step potentials.
