 Sherman Oaks Galleria The Sherman Oaks Galleria consists of the following elements:
- 700,000 sq. ft. of Class "A" office space
- 300,000 sq. ft. sq. ft. of retail, fashion, restaurant and entertainment
on three levels
- 3,535 user-friendly parking stalls
Syska Hennessy Group was responsible for the complete building
systems design and construction administration for the conversion
of the mall into a mixed-use facility incorporating commercial office
space and retail/entertainment space.
Optimizing energy efficiency and system performance for creating
this "green building" was key in our design phase. This process
required an integrated design process with contributions from all
of our major design partners. Described below are some of the key
elements of our design, it is important to remember that although
the elements are described separately as sustainable, electrical,
lighting and mechanical- all of these were looked upon as 'one'
in completing a successful mixed-use project for our client.
Highlighted Sustainable Elements
With the help of a Rocky Mountain Institute workshop, Syska Hennessy
Group and the design team helped developed the DOE-2 energy model
used in the life cycle cost analyses of various sustainable design
strategies. The LCA's resulted in the integration of super-efficient
glazing systems, solar shading devices, light shelves, light wells
and skylights for day lighting and the recommended use of EnergyStar™
rated office equipment. These load avoidance strategies resulted
in the reduction of the building chilled water plant by approximately
30%. The HVAC system utilizes high efficiency chillers, cooling
towers and primary/secondary pumps, and the piping and air distribution
systems are oversized to promote a low pressure, low energy system.
Electrical Systems
An electrical challenge for the design team was to utilize the existing
electrical systems infrastructure to accommodate the varied needs
of the retail, entertainment and office client's. Due to the increased
electrical demands of the new facility, the design team worked with
the Department of Water & Power to increase the power voltage allowance
and also designed step down's to sub-stations to enable the team
to provide sufficient power to the different segments of the project.
Sherman Oaks Galleria's natural lighting
design.

Lighting Systems
The natural lighting design called on Syska's electrical engineers
to design an efficient lighting system that was controlled in response
to the available daylight. At the Sherman Oaks Galleria our engineers
coordinated with the design team to create and implement a simple,
yet efficient sensor system. The sensors had the capability to measure
the natural light in the office space and would turn on the artificial
lights when needed to compliment the natural light. The sensors
also had the capability to turn on the lights when a person occupied
a space and turn off the lights when they exited their respective
space.
Mechanical Systems
When properly designed and implemented, natural ventilation strategies
provide the dual benefit of energy savings and improved indoor air
quality. Our mechanical engineers look for opportunities to reduce
or eliminate mechanical air conditioning in favor of natural ventilation
at the Galleria
An example of where we implemented natural ventilation was at the
entrance of the Pacific Theatres where an Atrium was designed to
allow for both natural lighting and ventilation. Also, a skylight
was designed to connect two of the buildings to allow employees
and visitors the opportunity walk outside for natural ventilation
while having the protection of the skylight from the sun.
In addition to the above, the mechanical system implemented and
designed utilized high efficiency chillers, cooling towers and primary/secondary
pumps, and the piping and air distribution systems were oversized
to promote a low pressure, low energy system. Unfortunately, for
this project an under floor air supply system did not provide the
necessary life cycle cost to meet the client's payback criteria.
PROJECT IMPACT
The Sherman Oaks Galleria was once known as the home of
the "Valley Girls" in Southern California. Today, it has been reborn
as a new retail, entertainment and office complex for the center
of the San Fernando Valley. Featured in numerous Los Angeles Times
articles and a recent special on the Public Broadcasting Station
the Sherman Oaks Galleria has become the focus for Southern California
Entertainment.
The Sherman Oaks Galleria serves as a prototype for future mixed-use
facilities incorporating sustainable design elements with MEP and
architectural design.
