20 M Street

20 M Street was the first office building in Washington, D.C. to pursue and achieve GOLD certification, incorporating the most efficient and state-of-the-art design strategies for newly constructed buildings.

ENERGY STAR certified buildings save energy, save money, and help protect the environment by generating fewer greenhouse gas emissions than typical buildings. To be certified as ENERGY STAR, a building must meet strict energy performance standards set by EPA.

20 M Street is Fitwel certified in recognition of the evidence-based design and operations strategies that support the physical, mental, and social health of our occupants.

The building provides increased ventilation, pulling fresh air into the building and carefully filtering internal spaces, thereby greatly improving indoor air quality.

CO2 monitoring, humidification controls, air flow monitoring and low-emitting materials ensure a healthier work environment than non-LEED buildings.

A significant reduction in CO2 emissions compared to non-LEED® office buildings through the use of energy and water efficient equipment in the central plant. This reduces the strain on Earth’s most precious resource, water.

100% of the energy consumed comes from renewable energy sources providing the highest environmental benefit.

100% of storm-water from the roof is collected in a 17,000 gallon cistern and used to supplement the water used in the cooling tower, reduces the strain on Earth’s most precious resource, water.

Installed in 2022, the unique solar canopy design generates approximately 186,772 kWh of usable AC electric output annually.

As a model of green entrepreneurship and as an agent of change, building management collects and disposes of recyclables such as paper, plastic, glass, aluminum and other materials.

The building utilizes the latest green cleaning practices that eliminates the use of harmful chemicals.

20% of the building materials used in the base building construction were made from post-industrial recycled content, helping to reduce environmental and social impacts.

20% of the building materials used in the base building were extracted, harvested and manufactured locally.

Tenant are encouraged to maximize the use of daylight and views in design of interior spaces. By optimizing the amount of natural daylight in the workspaces, businesses improve working conditions and boost employee wellness, satisfaction and morale.

A highly efficient glazing system with low-e glass keeps the building cool in the summer and warm in the winter. Improving temperature and humidity control provides a comfortable working environment.

The below-grade parking and light-colored, heat-reflective roof system minimize the building’s contribution to heat-island effect and relieve the cooling energy load during hot summer months.

The building’s high performance glass, energy efficient lighting, air conditioning controls, and free cooling systems contribute to the buildings superior energy performance. A computerized Building Management System allows for monitoring and control of energy use.

The use of water-efficient fixtures in the building reduces the demand for water needed to operate the building by 33% compared to non-LEED office buildings.

20 M Street offers direct access to public transportation, including The Navy Yard-Ballpark Metro Station located on the Green Line, and numerous bus lines nearby.

20 M Street has a WalkScore rating of 86 for accessibility and convenience to dining and services.

With a BikeScore of 90, it’s a “bikers’ paradise” with on-site access to ample bicycle storage and shower facilities, Preferred parking spaces are provided for fuel-efficient vehicles in addition to a conveniently located charging station for electric vehicles.
