Washington, DC

Setty renovated the HVAC systems in this occupied 750,000 sf historic building, consisting of office space and a food court with a 12-story atrium, generally used for concerts and other functions. A detailed and collaborative work plan, enabled phased work to be completed on weekends, so systems were up and running for full occupancy on Monday.

Listed in the National Register of Historic Places, the Old Post Office (OPO) is slated as the permanent home for the National Endowment for the Arts.

Scope of services included:

  • Replacement of the building’s four main HVAC air handling units (AHU) and the food court chiller.
  • Furnished and installed two new quadrant Variable Air Volume (VAV) AHU components.
  • Sized new AHUs consistent with design needs and occupancy expectations.
  • Furnished and installed heating coils for tempering of the makeup air, adding them to all four AHUs.
  • Replaced the dampers, motors, and actuators on air handlers, outside air, return air, and relief air dampers.
  • Furnished and installed new controls system for AHUs. Connected controls from all four AHUs to the existing EMS on the second floor. Tested and adjusted new controls system to ensure compatibility and functionality with existing EMS.
  • Provided electrical support services for the provision of the temporary fresh air supply.
  • Provided Variable Frequence Drives (VFD) for new motors.
  • Design-build services for the replacement of food court chiller.
  • Compliance of Historic Preservation and Protection requirements.

Setty provided Design and Construction Management services for the upgrade and replacement of the fire and life safety systems, and complete integrated ceiling system, including all lights and diffusers, for this 1,600,000 sf federal building.

The project was divided into more than 26 phases, with work in occupied areas performed at night, to allow all tenant operations to remain fully functional. The resulting design and implementation of new systems provided higher-efficiency operating equipment and fully accessible ceiling, with lower energy consumption.

Two types of life safety improvements were addressed. The first, provided complete automatic sprinkler systems. The second, involved replacing the fire alarm system, and identifying the areas that required fire protection in order to meet current life safety criteria for sprinklers and fire alarm annunciation/voice evacuation.

Upon our recommendation, the entire air distribution system was analyzed and the HVAC load calculations performed to accurately reflect the present day building conditions. The new load calculations proved air quantities that differ from the those provided under the original design, identifying inadequacies in the current air distribution system.

Solar support and sustainable design were utilized to demonstrate the impact on energy savings by initiating photovoltaics with necessary structural support system. We also evaluated the feasibility of a green roof. Important features included energy-efficient HVAC & Lighting Design, LED Lighting, and conversion of lighting from T-12 to T-8.


  • In order to ensure continuity of operations, construction was planned over three years, and included constructing a 30,000 sf swing space facility.
  • Management of submittals and schedule.
  • Record keeping and documentation.
  • Requests for Information.
  • Modifications of Contract.
  • Budget Cost Accounting.
  • Periodic Reports: Testing & Evaluation
  • Progress Reports.
  • Scheduled construction progress meetings.

The end result is a safer, more reliable, energy-efficient, installation of critical building components that is among the few federal buildings in D.C. that has earned an Energy Star rating.

(CHP) + Net Zero Study | Washington, DC

SETTY is investigating the feasibility of using an innovative combined heat and power (CHP) plant to serve four schools located in the District's new Southeast Eco-District. Because CHP plants effectively recover waste heat from the production of electric power, overall power plant efficiency is improved and the goal of NZE becomes more attainable.

Additionally, by using a biomass-powered fuel cell as the CHP's prime mover, on-site generation of renewable energy-a central tenant of NZE building design-is achieved. In the end, SETTY's proposed design not only realizes NZE, but it is projected to save the District over $300k per year in utility costs.

Setty performed Central Plant Utilities Analysis and Review, providing in-depth surveys and preparation of Construction Documents for the installation and monitoring of sub-meters by the existing Supervisory Control And Data Acquisition Systems (SCADA). The survey included the analysis of maintaining software controls and hardware capability for future integration into other systems.

Specifications included requirements for a Dashboard with the following features:

  • Overview of menu selection screen which allows user to select any power meter of interest.
  • Menu selection ability to include pre-existing power meters under the SCADA system.
  • User capability to specify the date range for historical data trending, from current date to a five years prior.
  • Screen format to fit the physical dimension of the LCD.
  • Capability to print report.
