The City National Plaza, a 38-year-old twin-tower complex encompassing 2.5 million square feet of office and retail space, has been certified with LEED-Gold under the Existing Building (EB) section by the United States Green Building Council (USGBC).
TPG has made key energy-saving capital investments such as chiller replacements, lighting retrofit and exterior wall sealing to make the building energy-efficient. With an Energy Star score of 83, City National Plaza is 33% more energy-efficient than an average US office building.
City National Plaza’s corridors provide views in all directions, with the efficient, column-free design accommodating various tenant layouts. Originally completed in 1972 as the world headquarters for Atlantic Richfield and the Southern California Headquarters for Bank of America, City National Plaza consists of two 51-story office towers, one plaza level building and four subterranean levels. The towers rise above a plaza level and consist of steel structured frame covered with polished panels of Forest Green granite and panes of bronze glass set in a distinctive pattern.
Owners Thomas Properties Group and the California State Teachers’ Retirement System have worked in partnership to upgrade the project since acquiring it in 2003.
The City National Plaza’s LEED-Gold recognition is a major milestone in meeting TPG’s goal to be the first major property owner to convert its entire national portfolio to LEED-rated ‘high performance’ properties by the end of 2011. Four properties have already secured LEED certifications, seven more are on track in the LEED program and four planned developments have achieved LEED pre-certification.
