The Lanes, 400 Florida Ave NE, is a residential project built in the NOMA neighborhood in Washington, DC. The project consists of 110 apartment units. Limited ground floor retail areas will be included in the project which will be built out by future tenants.






  • Open space has been created for over 40% of the site area as an amenity and counter to the surrounding urban density. This includes plantings and rooftop amenity spaces. Over 30% of the total site has been restored with native or adapted vegetation providing habitat due to the project’s green roof.

  • The parking footprint has been drastically reduced in a location with ample walking, bicycling, and public transit options. Only three parking spaces are provided on-site.

  • On-site parking includes a single Level 2 dual electric vehicle charging station.

  • Low flow water fixtures installed in the building save over 41% compared to the LEED baseline. Water savings from efficient fixtures save an estimated 2,064,310 gallons of water per year. Plumbing fixture flow rates are below:

    • Lavatory faucets – 1 gallon per minute

    • Toilets – 0.96 gpf on average dual flush rate

    • Showers – 1.5 gallons per minute

    • Faucets – 1.5 gallons per minute

  • The landscape design results in additional site water savings due to use of drip irrigation. Water savings from the landscape design are an estimated 96% or 10,149 gallons of water in the peak summer watering month compared to the LEED baseline.

  • The project has been designed to meet and exceed ASHRAE 90.1-2010 energy standards. A whole building energy model was developed to determine the building’s energy performance and savings. The projected energy savings are 17% in energy cost compared to the ASHRAE 90.1-2010 baseline. Savings come from the following measures:

    • Solar photovoltaic system mounted on the building roof.

    • ENERGY STAR appliances (refrigerators, dishwashers, clothes washers) are installed in all dwelling units.

    • High-efficiency central hot water with 96% efficiency boilers

    • Apartment water source heat pumps with 11-13 EER efficiency

    • Common area lighting controls including occupancy sensors in corridors, stairwells, amenity areas and back-of-house spaces

    • Daylight sensor lighting controls in amenity areas

  • Over 30 Environmental Product Declarations (EPDs) were provided for materials used in the project. These provide detailed life cycle information on the environmental impact of material or product. 20 Health Product Declarations (HPDs) were included for materials detailing effects on human health.

  • In addition, recycled content materials total over 15% of materials, by cost used in the building.

  • The project implemented a Construction IAQ Management Plan during construction. Absorptive materials were wrapped to prevent moisture damage, high-efficiency filters were installed, and ductwork was covered to prevent construction debris from entering the HVAC system.

  • Another measure to improve indoor air quality was use of low VOC paints, adhesives, sealants, and flooring. These permanently installed finishes were low VOC materials per LEED standards.
