Key innovations of the " Spark " in
Madison, Wis., include a dedicated and
demand-controlled outdoor air delivery
system with dual total energy recovery
wheels. This is paired with local fan coils
for zone control with energy-effi cient
fans.
Innovation, Resiliency
Create Cornerstone
Of Offi ce Tower Design
BY SHANA SCHEIBER, P.E., MEMBER ASHRAE, AND ROGER LAUTZ, P.E., MEMBER ASHRAE
The " Spark " in Madison, Wis., showcases American Family Insurance's
commitment to innovation, collaboration and entrepreneurship. The vision
for the 158,000 ft2 (14 679 m2), nine-story offi ce tower is to ignite innovation,
and the design followed that same goal. Key innovations include a dedicated
and demand-controlled outdoor air delivery system with dual total energy
recovery wheels, as well as geoexchange and redundant systems for resiliency.
Innovation
Fortifi ed Commercial construction measures,
including evaluating the 500-year fl ood zone
and designing for high winds and hail, were part
of the owner's project requirements. The building
includes a backup generator sized to keep all
building functions operational for 24 hours, geoexchange
and redundant chillers, boilers, cooling
towers and pumps for resiliency.
Because of its design, in 2018 the Spark managed
heavy rains, wind and historic fl ooding due to high
lake levels. During a 2019 nearby utility substation
fi re and subsequent fi ve-hour power outage,
the Spark maintained full power while on backup
power generation.
Key innovations (Figure 1) include a dedicated and
demand-controlled outdoor air delivery system with
dual total energy recovery wheels. This is paired with
local fan coils for zone control with energy-effi cient
fans on electronically commutated (EC) motors to
ensure quiet and comfort. Perimeter heating and
insulated spandrel where views are less essential
