Plumbing + Fire Protection + Fire Suppression | Washington, DC

Setty provided Plumbing/Fire Protection/Fire Suppression design services for Bridging Documents to meet Silver LEED rating for the New U.S. Coast Guard Headquarters Building.  The new building, central plant and 1,000 car parking garage are approximately 3.5 million sf, multi-level, with special use facilities.  The parking garage contains a green roof and a living exterior wall, and is to be fully sprinklered - dry system, below grade sections only.

The 25,000 sf Central Plant is designed to contain centralized chilled water and hot water utilities to support the new building and parking garage.  All structures are connected via a tunnel network for utilities and access.  The campus will be monitored by a single control system that will access fire alarm, energy management and security systems.  The building is a 9-level structure built into the side of a steep grade.  There are large rainwater harvesting ponds centered in the building courtyards.  Also included is a Setty-designed greywater recycling system.

Dunbar High School | MEP/FP Design + BAS + Energy Modeling | Washington, DC

As part of the District’s program to modernize DC schools, the historic Dunbar High School was demolished and replaced with a new 276,536 sf building designed to include

state-of-the-art sustainable features.

Sustainable Design features incorporated:

  • Living Classrooms: Educating the students about High Performance Buildings by highlighting those features in their school with plaques
  • Renewable Energies: The largest urban geothermal system in DC, at 850 tons, and 362 vertical wells, drilled to 460 feet deep, located below the football field.
  • Renewable Energies: Solar panels with total output from the photovoltaic array of 482.3 kW.
  • Indoor Air Quality: Low VOC construction materials utilized.
  • Automated Energy Saving Systems: Enhanced lighting controls *with occupancy sensors and timers
  • Radiant floor heating *
  • Rainwater Harvesting: Utilizing two 20,000 gallon cisterns for collecting and reusing rainwater.

The design is expected to produce 26.92% energy savings, and 28.2% cost savings, in comparison with the baseline design.

GSA: Department of Energy Forrestal Building

Washington, DC

GSA, Department of Energy, Forrestal Building | A/E Services + CM Services | 
Washington, DC

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.

DESIGN SERVICES:
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.

CONSTRUCTION MANAGEMENT SERVICES:

  • 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.

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.

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.
