This office building is the first office building in the world to achieve LEED Gold re-certification under LEED O+M: Existing Buildings v4.

WASHINGTON, DC August 23, 2016 —
The Tower Companies (Tower) announced today that it has received a recertification of LEED (Leadership in Energy and Environmental Design) Gold under the LEED for Existing Buildings: Operations and Maintenance rating system (EBOM) at 1828 L Street NW, a multi-tenant commercial office building, located in the Golden Triangle, in Washington D.C. The 424,000- square- foot building is currently the first commercial office building in the world to recertify as LEED Gold under LEEDv4 and the highest recertified project in the National Capitol Region under (O+M): Existing Buildings rating system. The building originally achieved LEED Gold certification in 2011 under EBOM v2009.

Tower is a family-owned real estate development and management company with a lasting commitment and vested interest in sustainability. In 2004, Tower achieved its first LEED certification, in the United States, for Blair Towns, a multi-family residential property, and has continued to strive for LEED certification at all existing properties and new developments. Currently, 90 percent of Tower properties are LEED certified. Paladino and Company (Paladino), an industry-leading green building and sustainability consulting firm, managed the LEED recertification project, in addition to, the original certification almost five years ago.

“We always make an effort to consider the impact of sustainability and overall well-being of all stakeholders,” said Eugenia Gregorio, Vice President, Strategy & Sustainability, for Tower. “The project team works tirelessly and continually enhances efforts to ensure that all building tenants and visitors are given the best possible work environment.  We are very enthusiastic and proud to earn this certification and to continue our commitment to being a leader in the industry.”

Through a joint collaboration, 1828 L Street earned well-deserved credits for the team’s successful implementation of water and energy conservation measures, waste management strategies, indoor air quality programs, and an alternative transportation tenant survey. The team also received recognition for innovative tenant engagement programs including green teams and a CSA program, in addition to, a robust health and wellness offering of fitness classes, an on-site health and wellness fair, wellness screenings, vaccination clinics, and various related seminars year-round.  All of these programs are made available to every building tenant. Additionally, Tower strives to inform building staff, tenants, vendors, and visitors about the LEED certification program and other sustainability best practices that add value to the user experience.

“The recertification of 1828 L Street under LEEDv4 is a prime example of how a company consistently raises the bar when it comes to sustainability,” said Rick Fedrizzi, CEO and founding chair, USGBC. “While climate change is a global issue, companies like Tower are demonstrating that there are local solutions to reduce electricity costs and carbon emissions and create healthier built environments. With every new LEED certified building, we get one step closer to USGBC’s vision of a sustainable built environment within a generation.”

Tower strives to implement the most efficient operations and reduce utility costs for tenants across their portfolio.  The team successfully documented that the building’s use of low-flow fixtures resulted in a savings of over 32% compared to the established baseline, while conserving 5.5 million gallons of water since 2010. In addition, the building’s energy performance ranks in the top 14% of similar buildings nationwide and has saved 3.5 million kWh of electricity since 2010. These efforts further  their commitment and partnership with  The Department of Energy’s Better Building Challenge to reduce both water and energy consumption 20% by the year 2020.

“Paladino has a longstanding relationship with the Tower Companies, and we understood their commitment to sustainability, which they validate through LEED certification across their portfolio,” said Rachel Sowards, Executive Director at Paladino and Company. “Tower’s choice to recertify under LEED v4 was completely voluntary. They wanted to set the precedent that v4 is both achievable and worthwhile to the business, and their people.”
