The Bachelor Enlisted Quarters (BEQ) built for the U.S. Navy in Yorktown, Virginia, was constructed on the site of a previous barracks and provides housing for Navy personnel.

Environmental Aspects

The most important environmental goals for the project were creating greenspace, providing good indoor environmental quality, and limiting construction waste.

The project team limited the building footprint to less than 10% of the total site. The team also allowed native grasses to cover the resulting landscape, limiting the need for irrigation and controlling stormwater runoff and erosion. Efficient fixtures reduce indoor water consumption by 36%, compared with a comparable conventional building.

All paints, adhesives, sealants, carpeting, and composite woods used in the project contain low levels of volatile organic compounds. Occupants have individual controls for lighting, heating, and air-conditioning, while occupancy sensors ensure that systems are turned off when room are unoccupied. In addition, the building's conditioning systems do not use ozone-depleting refrigerants.

More than 90% of the construction waste from the project, by weight, was diverted from landfills. The project team specified materials with recycled content as well as local materials and wood certified to Forest Stewardship Council standards.

Finance & Cost

The funding for this project came through the federal governmental appropriations process for military spending in 2003.

  • Equity: Government appropriation

Cost data in U.S. dollars as of date of completion.

  • Total project cost (land excluded): $11,500,000

Land Use & Community

The Bachelor Enlisted Quarters (BEQ) was built on the site of an older barracks that had to be torn down. The project team maintained existing parking lots and access roads. The team also included bicycle storage in the building, and some parking spaces are reserved for carpool and vanpool vehicles.

  • Support for Appropriate Transportation

    • Provide showers and changing areas for bicycle and pedestrian commuters

    • Provide storage area for bicycles
    • Provide vehicle access to support car and vanpooling
  • Property Selection Opportunities

    • Select already-developed sites for new development

Site Description

During construction, contractors took precautions to control erosion and sedimentation: they used inlet protection, silt fencing, straw bales, gravel check dams, seeding, and a stone construction entrance. The team also removed existing impervious areas—including a tennis court, a swimming pool, and some parking areas—reducing the site's impervious area by 50% (excluding the building footprint).

After construction, 91% of the total site area was left as open space vegetated with native grasses; these areas improve stormwater infiltration and do not require irrigation. An open-grid paving system was used for the fire lane to further improve stormwater management and to reduce the project's contribution to the urban heat-island effect. In addition, shading was provided for at least 30% of the site’s non-roof impervious area. The roof itself is reflective and has a high emissivity.

Exterior light fixtures use a full-cutoff design, which directs light downward, reducing nighttime light pollution.

  • Lot size: 326,426 ft2
  • Building footprint: 17,400 sq ft (1,620 sq meters)
  • Pristine land (greenfield), Preexisting structure(s), Previously developed land

Water Conservation and Use

Low-flow showerheads and faucets reduce indoor water use by 35.5%. The turf chosen for the site does not need irrigation, eliminating outdoor potable water use.

Water Use - Outdoor potable water use: 0 gal/yr (0 liters/yr)

  • Runoff Reduction

    • Reduce driveway pavement
    • Use modular block paving
  • Landscape Plantings

    • Landscape with indigenous vegetation
  • Low-Water-Use Fixtures

    • Retrofit faucet aerators or flow-regulators onto lavatory sinks
    • Install faucet aerator on kitchen faucet
    • Install showerheads using less than 2.2 gallons per minute
  • Construction Impacts

    • Minimize soil erosion from construction activities
  • Low-Impact Siting

    • Select building sites that make use of existing infrastructure


The building uses high-efficiency, pulse-type, natural gas condensing boilers. The main air handler has a highly efficient motor.

The Pacific Northwest National Laboratory measured the project's energy use and found it to be lower than predicted in a 2006 simulation.


Materials & Resources

The project team sought local materials; as a result, 34% of the project’s materials, by cost, were manufactured within 500 miles of the project site, and 20% of the project’s raw materials originated within 500 miles of the project site.

Most of the wood products used in the project (76%, by cost) are certified to Forest Stewardship Council standards.

Recycled-content materials represented 6.43% of all materials used in the project, as per LEED measurements, and a space was designated in the building for resident recycling.

The conditioning equipment used in the project contains no ozone-depleting chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or halons.

A construction waste management plan developed by the contractor diverted 93% of the waste, by weight, from landfills.

  • Protection of Global Ecosystem

    • Minimize ozone-depletion potential of refrigerants in cooling systems

  • Job Site Recycling

    • Require a waste management plan from the contractor
  • Recycling by Occupants

    • Specify recycling receptacles that are accessible to the occupants

  • Materials and Wildlife Habitat

    • Use wood products from independently certified, well-managed forests for finish carpentry

  • Transportation of Materials

    • Prefer materials that are sourced and manufactured within the local area

Indoor Environment

A number of construction and operational strategies protect the project's indoor environmental quality. Materials used in the building were selected for their low levels of volatile organic compounds (VOCs): low-emitting paints, carpets, adhesives, sealants, and composite wood were all used. Smoking is allowed only in designated outside areas, and a permanent track-off mat at the entrance reduces the amount of dirt and other pollutants tracked into the building.

The project team met ASHRAE standards for ventilation and thermal comfort, and installed permanent monitoring and control devices to ensure continued high performance. Individuals have control over lighting and conditioning in their personal spaces and have access to operable windows and views of the outdoors.

  • Entry of Pollutants

    • Design entry to facilitate removal of dirt before entering building

  • Thermal Comfort

    • Maintain relative humidity levels between 30% and 60%
    • Provide occupants with the means to control temperature in their area

  • Visual Comfort and Light Sources

    • Provide occupants with control of light in their area
  • Ventilation and Filtration Systems

    • Provide occupants with access to operable windows
  • Reduction of Indoor Pollutants

    • Use only very low or no-VOC paints
  • Ventilation During Construction

    • Use adequate ventilation during installation and curing of thermal insulation

  • Building Commissioning for IEQ

    • Commission the mechanical and electrical systems prior to occupancy

  • Facility Policies for IEQ

    • Recommend a non-smoking policy for the building
