responsible building management

We believe that responsible operating practices go hand in hand with generating value for our shareholders, providing efficiency and comfort for our tenants, and being good neighbors within our urban communities.

Across our national portfolio, we engage in sustainable practices that drive value, efficiency, and quality of environment for our stakeholders. We require our property management teams to practice responsible property management as well as energy and water conservation and encourage our tenants to do the same.

The effectiveness of our sustainable and responsible operations is evidenced by the recognition our properties have received from some of the most respected third-party organizations that benchmark property efficiency and sustainability.



We track the performance of our entire portfolio* through the EPA’s ENERGY STAR® benchmark program and are proud that over 82% of the office buildings in our portfolio are ENERGY STAR-certified for superior energy efficiency, responsible water usage, and reduced greenhouse gas emissions.

In 2015, we became a Premier Member of the ENERGY STAR Certification Nation and were a 2013 ENERGY STAR Partner of the Year.

In our portfolio, nine of the buildings – representing over 4.3 million square feet of office space – have been certified as meeting one of the exacting standards of the U.S.G.B.C.’s Leadership in Energy and Environmental Design (LEED®) green building program.

Beyond just achieving LEED certification, we have maintained certification for our properties that first earned the designation more the five years ago and continue to evaluate the portfolio to identify and pursue additional opportunities to enhance the value and appeal of our properties through LEED certification.
