Our Commitment To Sustainable Real Estate Development

Many of the nation’s most forward-thinking and successful companies have embraced LEED® (Leadership in Energy and Environmental Design) because they realize the diverse benefits and best business practices associated with sustainable design and development. These industry leaders recognize that by optimizing the work environment of their employees, they are able to increase productivity and profitability and decrease turnover. Furthermore, they know that LEED certified buildings minimize environmental impact through such best practices as the use of recycled and locally-sourced materials, reduced consumption of precious natural resources and the effective management of carbon dioxide emissions and stormwater runoff. 

At Lerner, minimizing the impact of development on the environment is one of our bedrock principles. The organization is committed to building and operating high performance buildings that are resource-efficient and create healthy environments for occupants. Through smart planning and the use of state-of-the-art design, materials and construction techniques, Lerner has become an established leader in green building.


Design is applied to new and existing buildings, to ensure that fresh air is being pulled into the space and air is filtered internally to improve indoor air quality.

Green Space

Our buildings are located close to parks and other green space. Whenever possible, we maximize open space and create a scenic environment for employees and visitors to enjoy.

Daylight & Views

We design buildings and encourage workplace build outs that optimize access to daylight and views. Optimizing the amount of natural daylight in the workspace improves working conditions and boosts employee wellness, satisfaction and morale.


Our properties are located in areas that maximize connectivity and reduce car usage, providing access to public transportation, including Metro Stations and bus lines, as well as bike share stations and walking paths.

Recycled Content

In the development process, we use building materials made from post-industrial recycled content as much as practicable, helping to reduce environmental and social impacts.


On a daily operating basis, we collect and responsibly dispose of recyclables such as paper, plastic, glass, aluminum and other materials.

Locally-Sourced Materials

We use building materials that are extracted, harvested and manufactured locally as much as practicable in the development process to minimize environmental impact.

CO2 Reduction

We carefully monitor energy use at our properties to help reduce CO2 emissions and encourage tenants to do the same. This helps reduce operating costs and our impact on climate change

Water Efficiency

We use water-efficient, native and adapted plants to reduce the demand for water needed for growth, ensure reliable water sources and create aesthetically appealing grounds for Tenants and visitors. This reduces the strain on Earth's most precious resource, water.

Green Energy

We maximize the use of green energy sources such as solar and wind power.

Alternative Transportation

The operational amenities and efficiencies at our properties encourage use of alternative transportation by such measures as providing access to bicycle storage, preferred parking spaces for fuel-efficient vehicles, and electric vehicle charging stations.

Reduction of Heat Island Effect

The highly reflective and emissive cool-roof system is designed to minimize the base building's contribution to heat-island effect and relieve the cooling energy load during hot summer months.
