CALMAC, a leader in energy storage systems, today announced the installation
of its IceBank® thermal energy storage tanks at the California State Lottery
Headquarters in Sacramento, Calif. The old, inefficient building was replaced
by a new building, which now consists of retail, exhibition and office space
plus a net-zero multi-purpose pavilion. It is designed to not only be energy
efficient, but to meet the requirements for Leadership in Energy and
Environmental (LEED) Gold certification.

Sustainable features of this new facility include a photovoltaic system,
thermal energy storage, daylight harvesting, window glazing, radiant floor and
green roof areas. Interface Engineering worked with CALMAC and Trane, a
leading global provider of indoor comfort systems and solutions and a brand of
Ingersoll Rand, to upgrade the central utility plant, which produces cold
water to feed all the buildings on the campus.

The thermal energy system and photovoltaic (PV) solar panels are also sized to
classify the pavilion as a net zero energy building. This means the pavilion
uses no more energy than is provided by its on-site renewable energy sources.
At night, ice is made using energy from the grid. During the day, PV produces
energy, which offsets the night-time energy. Excess energy is utilized to
offset energy consumption in the rest of the building. This use of distributed
energy storage and solar energy is especially noteworthy because the State can
rent out the conference spaces in the pavilion to generate revenue while its
use of day-time energy costs nothing.

“The focus of the State was on energy efficiency that was fiscally
responsible,” said Mike Stanton, Interface Engineering. “Besides helping meet
targets for modeling energy efficiencies that beat CA Title 24, the pavilion
was also net zero and helps supply renewable energy to the rest of the

“Net zero energy is a building market transformation that will eventually be a
requirement. In California, for example, buildings will need to be
self-sufficient by 2030,” said Mark MacCracken, CEO of CALMAC. “Building
owners should prepare to use less energy and generate the rest. Distributed
energy storage helps with this preparation by working with renewables to help
buildings operate more efficiently.”


CALMAC Manufacturing Corporation is transforming how energy is used at
buildings to the time energy is used. Widely recognized for promoting peak
energy conservation and energy cost savings CALMAC is a member of the U.S.
Green Building Council (USGBC) and the California Energy Storage Alliance
(CESA). CALMAC is the manufacturer of IceBank® Energy Storage equipment, with
over 4,000 Ice Storage installations worldwide. IceBank systems are a valuable
component of the smart grid, enabling energy, including renewable wind energy
that mainly blows at night, to be efficiently stored for use during periods of
high demand.
