Setty provided an Energy Conservation Study and Energy Audit...

The Veterans Administration (VA) Headquarters was construction in 1919. The building has a floor area of 684,629 gross square feet and is constructed of concrete and monolithic limestone. Eligible to be listed on the National Register of Historic Places, the ideal Energy Conservation Plan included accomodation for it’s aesthetic and historic significance.

Central Plant equipment was evaluated and found to contain well sorted energy systems. Terminal equipment, modulation valves, and Buidling Automation Control (BAC) were determined to hold the greated net value for energy savings. One thousand Variable Air Volume (VAV) boxes were identified as malfuntioning. Site Analysis determined these defective VAVs to be causing their respective Air Handling Units (AHUs) to operate at full capacity continuously. Additionally, the AHUs were inspected and found to have frozen modulation valves. These problems were calculated to be wasting significant energy and human resources.

A key element of the Setty Energy Conservation Plan, was the development of a targeted legacy equipment phase-out strategy. This strategy mitigated concerns regarding equipment downtime, and provided for a seemless and non intrusive repair schedule. Reports based upon ASHRAE Level II Audit.

Examples of Energy Conservation Measures included:
Occupancy Schedules, Night Setbacks, Optimum Start programming, Trending Protocols, Equipment Staging, and Control Logic Strategies became the focal points for improving BAC efficiency.

Scope of services included:
Site Analysis identified defective VAVs and AHU frozen modulation valves to be wasting significant energy and human resources,

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.

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.

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.

GSA, Leo W. O'Brien Federal Building | Retro-Commissioning | Albany, NY

Setty provided Retro-Commissioning and an HVAC tune-up study to include planning, identification of energy conservation and water conservation opportunities, scoping, testing, investigation, evaluation, analysis, calculations, recommendations, and report writing services for this federal building. We identified inconsistencies within the building systems operation via a series of functional performance tests targeted at the primary energy users, focusing on the HVAC systems.

Functional Performance Tests found that sequences deviated greatly from the contract documents. Additional system deficiencies were related to incorrect/incomplete logic programming within the Building Automation Control (BAC) systems. Setty controls technician made on the spot programming changes during the RCx process to bring systems into specification, based on the approved Sequence of Operation (SOO). The Building Automation Control (BAC) system graphics lacked continuity between screen representations, and did not completely adhere to GSA’s labeling conventions. These were either corrected on the spot, or scheduled to be corrected in the future. Additionally, equipment schedules and Optimal Start Sequences (OSS) were not functioning properly during testing.

Through our rigorous testing and implementation follow-up, building operations were able to achieve annual operating energy savings upwards of 20%, without sacrificing current operations or occupant comfort. Setty followed ASHRAE guildeline zero, and utilized the existing BAS airflow measuring stations to ensure proper air turnover rates and ventilation levels, trending the OA metrics to provide empirical reports.
