The Emerald Plaza Building

The iconic Emerald Plaza is San Diego’s most distinctive building to shape its skyline. The hexagonal green neon halos glow each night acting as a beacon for visitors and a symbol of downtown revitalization for San Diego businesses and residents.

In 2007, The Emerald Plaza building became home to the Westin San Diego and has benefited from the unique architectural design of its hexagonal towers ever since. Every room at the Westin San Diego is unique, many with panoramic views of the Pacific Ocean, San Diego Bay, Coronado Island, Point Loma and the Cuyamaca Mountains. The building has 12% more exterior window surface than comparable square or rectangular shaped towers, due to its hexagonal shape. The tallest tower is 30 stories and 400 feet tall and the structure’s eight rooftops are angled at 33 degrees to match San Diego’s latitude.

The Emerald Plaza building is centrally located in the heart of downtown, adjacent to the San Diego Trolley and one block from the Coaster and Amtrak Station. The San Diego International Airport is three miles away and all major freeways are easily accessible.

The Hexagonal Design

Construction

Emerald Plaza’s hexagonal design allows for the maximum number of guestrooms and offices with views, as well as minimizes wasted space typical to rectangular buildings. Further more, this design utilizes angled window sills, which reflect ambient sunlight into the building, reducing lighting requirements. The Emerald Plaza was built in 1990 at a cost of $150,000,000.  It is comprised of a steel frame structure with an exterior combination of granite stone panels and reflective glass set in a custom Kynar green aluminum window framing system. The structure itself is balanced on a 5-foot deep concrete block which acts like a floating device, allowing the building ebb and flow, mimicking the movement of water. This technique makes it one of the most stable structures in San Diego.

Gracing the interior of the building are more than 30 types of marble and granite quarried from Portugal, Norway, Spain, Italy and Africa. Known to have some of the fastest elevators in the United States (850 feet per minute), to fresh air vents which eliminate sick building syndrome, attention was paid to every detail.

Design of the Building

The design of the building was intentional and was developed & constructed with Feng Shui principles in mind. Recognizing that the universe is a fully integrated energy system, the hexagon was chosen for its structural integrity. The hexagon is actually comprised of interlocking triangles which are the building blocks of nature. The study of crystals further inspired the design of the Emerald Plaza as most crystals found in nature consist of a series or cluster of hexagons.  They are also organic in form and are believed to have healing and spiritual properties. As it is employed in the building, the hexagon allows for shorter hallways and more visual stimulation than that of rectangular structures.  It also creates interesting interior volumes, maximizing daylight.

Emerald Gemstone

Like crystals, the Emerald Gemstone is known to harmonize and strengthen the positive influences of mercury which includes intelligence, education, speech, communication, confidence, humor, wit, and intellect. The Emerald Gemstone helps to lift depression and insomnia and promotes knowledge of the heart resulting in peaceful dreams. The Emerald has long been the symbol of hope and is considered by many to be the stone of prophecy.

The Architect                     

The architect, C.W. Kim’s intent, was to have you feel as if you were standing in the middle of a crystal as you enter the atrium. While standing in the atrium, you’ll notice many angles of light shining through the window panels, providing countless facets and reflections.  Kim likened the atrium to standing in the center of Superman’s Crystal Room, with the magic green crystal from which he acquired his power.  The sculpture hanging in the center of the atrium, created by Richard Lippold, completes this idea.

The Artist

Richard Lippold, a multi-media artist and one of the great sculptors of the 20th century, was the first ever living artist commissioned for the Metropolitan Museum of Art in New York City. His work can also be seen in the Lincoln Center, MetLife Building, Four Seasons Seagram Building, the Graduate Center at Harvard University in Cambridge, MA, the National Air and Space Museum in Washington, DC and in private estate collections of Nelson Rockefeller and Baron Felipe Philippe de Rothschild.

C.W. Kim is perhaps most responsible for bringing Lippold and his sculpture to San Diego. The local architect had been pursuing Lippold for more then a decade, having tried unsuccessfully to get the artist to create sculptures for the Kim-designed First National Bank Building and the San Diego Marriott.

The sculpture was fabricated on the East Coast and then delivered in pieces for assembly. The artwork represents the Emerald Plaza’s contribution to the Center City Development Corporation’s public arts program, which requires developers to devote 1% of construction costs to public art.

The Flying Emeralds sculpture hangs in the center’s 100 foot high glass atrium. It has five hanging elements, each hexagonal in shape and resembling a metallic oriental lantern. Hanging from the outside of each element are long hexagonal prisms made of polished aluminum and hanging from the inside are sheets of emerald green acrylic.

Energy Efficient

In addition to its aesthetic beauty, The Emerald Plaza building is also one of downtown San Diego’s most energy efficient buildings due to its computerized energy management system, thermal storage system and ice plant. Energy control systems including the H.V.A.C. (heating, ventilating, and air-conditioning) equipment, lighting systems, telecommunications, and electronic monitoring devices were a top priority in the design of the Emerald Plaza. In 2008, the building was granted the General Electric Energy Star Award. Currently, this award can be found in the office lobby.

One of the unique energy-saving systems utilized by the hotel is its chilled water systems. These mechanical structures utilize an innovative design to provide efficient and cost effective energy management. Each room in the hotel utilizes an individual fan coil air conditioning unit. The cooling to each unit comes from chilled water pumped through the system from the ice storage system located in the basement. In addition, each floor is equipped with separate air handlers and has fresh air ventilation louvers, optimizing energy savings and reducing “sick building syndrome.”

Our building has the largest TES system of its kind on the West Coast. Through the use of ice manufactured in thirteen 8' x 52' water storage tanks, we freeze 1,000,000 gallons of water, enabling the system to save our building an estimated $15,000-$18,000 per month in energy costs. As the water freezes, it has the capacity to release large amounts of heat energy. Large water storage tanks located below the parking garage store the ice. During late night and early morning, the electricity is used to run the air conditioning chillers and compressors. The cold water freezes and stores the energy until it is needed the next day. During the day the chiller and compressors are turned off and only the blower fans are needed to cool the building, resulting in a substantially lower electric load requirement during the day.
