HVAC Tune-Up + Energy Audit + Retro-Commissioning | Washington, DC

Setty provided Enhanced and Retro-Commissioning services. with a focus on energy conservation, operational efficiency of systems, individual component and enterprise system level analysis, integration and interoperability of systems, Life Cycle and technology analysis, and Energy Modeling. Functional Performance Testing (FPT) procedures were tailored to capture the most valuable information, and the resulting reports based upon ASHRAE Level II Audit for energy and water conservation measures.

Based on the information gathered, Energy Conservation Measurement recommendations were developed, including:

  • Re-Commission enthalpy control within BAC system.
  • Commission design review of basement AHU.
  • Repair and/or replacement of existing Outside Air, Exhaust Air, and Return Air automatic dampers.
  • Repair and/or replace all Chilled and Hot Water modulation and isolation valves.
  • Re-Commissioning of outside Air Economizer Mode within control strategy.
  • Calibration of field instrumentation.
  • Calibration of control logic for all Variable Frequency Drives (VFDs) and control loops.
  • Creation of a controlled phase-out program for obsolete and unsupported legacy controls infrastructure.
  • Repair of steam basin heater control valves.

Building Automation Control

+ Retro Commissioning    

Syracuse, NY

GSA: James M. Hanley Federal Building | Retro Commissioning | Syracuse, NY

Setty provided engineering and commissioning expertise to assess existing conditions, identify system defects, uncover energy conservation and water conservation opportunities, perform diagnostic testing and calibration of controls, and make recommendations via a Commissioning Report. Reflecting ASHRAE Guideline 0 recommended practices, GSA used the initial conditions assessment to identify defective equipment, which was then repaired for follow-up Functional Performance Testing efforts.

The 638 PTAC units were unregulated by the Building Automation Control (BAC) and utilized electric cooling and heating exclusively. Side-by-side PTAC units were identified to be simultaneously funning in opposite conditioning modes (one cooling, and one heating), both at maximum capacity and each physically separated by only 10’ of open undivided space. These were immediately identified as the most energy consuming devices, and a retrofit plan was developed. Water source heating and cooling architecture and a robust BAC system were determined to be the most plausible energy saving strategy. Although this water source system represented a multi-million dollar capital investment, an anticipated twenty-five percent total building energy reduction calculated a rapid return on investment. The new equipment would also be integrated into the BAC system to harvest even greater control and energy savings. Reports were based upon ASHRAE Level II Audits.

Lighting Upgrades and CM Services

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.

Gallaudet University | Chilled Water Plant + Controls Upgrades

+ Commissioning Services | Washington, DC

 The purpose of this project is to build on modernization efforts at Gallaudet University's (GU) Central Utilities Building (CUB) which have been occurring throughout 2015. This scope of work comprises five (5) separate projects which are considered mutually exclusive from each other operationally. These scopes of work are considered as follows:

  •  Engineering Design of Chilled Water Plant and Controls Upgrades
  • Chiller Plant Water-Side Economizer Heat Exchanger
  • Chiller Plant and Boiler Plant Controls Modernization
  • Campus Chilled Water System Controls Upgrades
  • President's House Boiler Upgrades
  • Secondary Chilled Water Pump Upgrades
  • Commissioning Services

The intent of the project management structure is that Setty will act as Gallaudet's Construction Management entity, representing GU's interests. Setty shall hold all construction/repair contracts, will have shared authority with the University over the subcontractors, and will be responsible for insuring their compliance with contract documents as designed by Setty. To capture th is structure, it is Setty's intent to enter into an AlA owner's representative contract.

Setty has been working with subcontractors who have been vetted by GU to develop scoping documents, and build budgets. This work has included multiple iterations of engineered design documents, site visits and meetings to discuss scope implications and constructability, and an iterative development of pricing.
