Setty performed an Enhanced Commissioning Study of the building envelope, lighting, heating, ventilation, and air conditioning system, for the 30,000 sf LEED Gold library, which includes a conference room and offices, as well.

The mechanical system is under floor distribution, with heating provided by electric under floor fan powered boxes. The fan powered boxes are re-heating air from two constant volume air handlers. Those units have electric heat, and feature a direct expansion cooling coil (DX cooling) and 55-ton condenser unit.

Scope of services included:

  • thermographic analysis of the building
  • review of building documents
  • implementation of operating schedules, optimizing air delivery systems, setting up temperature air side temperatures operations, optimizing indoor air quality, and verification of the controls systems functions.
  • Commissioning of acoustics suggested “white” background noise to minimize exterior noise of urban environment.
  • Energy modeling, utilizing e-QUEST
  • Detailed DOE2.2 model was developed to verify suggested cost saving strategies for the building.

Wheeler Terrace Apartments | MEP Design + Geothermal + Green Roofs + LEED |
Washington, DC

Setty provided the first geothermal system for a DC housing development, designing the new M/E/P systems for seven modules. Extending our support, we also provided LEED Gold certification administration and fundamental and enhanced commissioning services, as well. The affordable housing project boasts energy savings of 25%, which will be shared with the residents (a first in the nation).

The MEP systems are based around geothermal wells for each of the seven buildings (117 total units). Some of the LEED strategies incorporated are high-performance heat pumps, geothermal well field, green roofs, occupancy sensors, demand-control bathroom ventilation, recycled materials, a super heater for the domestic hot water, and high-efficiency lighting well below code.

Dept of Employment Svcs (DOES) HQ | MEP/FP Design + LEED + Daylight Harvesting
+ Green Roof | Washington, DC

Setty completed the construction drawings for this five-story Department of Employment Services (DOES) Building The 229,000 sf office and retail project earned a LEED silver certification. The design called for a contemporary façade that curves with the street, underground parking, abundant natural lighting, bicycle storage, electric vehicle charging stations, and numerous other environmentally responsible elements.

* As part of the DC Government Centers' initiative that places a new civic building in blighted areas in need of economic development, the DOES project accommodates approximately 500 agency personnel.

Scope of services included:

  • Design of HVAC, Electrical, Plumbing and Fire Protection systems.
  • Review of O&M manuals, participation and assistance with operations training.
  • Incorporation of airside and waterside economizers.
  • Lighting controls with daylight harvesting.
  • CO2 sensors to modulate outside air quantities.
  • Construction management and project management consistent with PME standards.
  • 26,000 sf Green Roof.
  • Combination wet/dry/standpipe automatic sprinkler system with fire pump.
  • Standby emergency generator for life safety systems.

HD Woodson STEM High School | MEP/FP Design + BAS + Green Roof 
+ Rainwater Harvesting + Pool Dehumidification Units | Washington, DC

Setty provided MEP/FP design services for this now LEED Gold certified 320,000 gsf building, the first newly constructed high school in DC in almost 40 years. 
The challenge was to not only comply with all requirements of the local constituency, but also establish the benchmark for all future DC schools by surpassing the goals of the local energy code, ASHRAE, and LEED. Despite its challenges, the project was completed on time and under budget, which is an incredible testament to the entire design and construction team given the project’s sheer size and lofty performance goals.

Pool dehumidification units were used to condition the large open natatorium space, with residual heat hydronically transferred over to the pool water via a heat exchanger. An airside economizer cycle was also utilized to condition the space when ambient conditions were optimal, to reduce the mechanical refrigeration requirements for the space. High-efficiency chillers and condensing hot water boilers were used to further improve the energy savings. All dedicated outside air units were also specified with integrated energy recovery wheels, and an automated building automation system (BAS) was installed to serve all of the equipment. 

Architectural floating acoustic clouds for sound baffling were suspended in the state-of-the-art auditorium, requiring resizing of all ductwork in order to fit and route it through the webbings of the truss system. All ductwork and major piping was modeled and checked for clash detection before any installation in the field, which allowed for a smoother construction process.

Scope of work included: 

  • Gymnasium, 1,200 seat state-of-the-art auditorium, indoor pool, wrestling room, fitness center and three level classroom towers.
  • New field house including stadium lighting.
  • Green roof and rainwater harvesting system for water closets and irrigation.
  • Telecom pathway (Enclosure, Conduit, Power and A/C).
  • Building Automation System (Energy, Fire and Security).
  • BIM Integrated 3D Design – Revit MEP 2009.
