New York Power Authority (NYPA) | ASHRAE Level 1 Building Energy Audits |
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,

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:
Setty performed a Feasibilty Study for Energy & Water Conservation of ten buildings (3,500,000 sf) at the FOC compound. The comprehensive study began with identifying existing conditions, benchmarks, and energy and water conservation measures, which led to the development of a proposed ten-year construction program that would address all federal sustainability mandates, as well as the client’s own LEED sustainability program goals. Eleven individual performance goals had to be integrated into a resulting roadmap, with each program year identifying progress toward each goal.
The energy audits conducted met ASHRAE Level-II Energy Audit standards, and resulted in over 160 energy conservation measures, and 40 water conservation measures defining feasibility, first costs, life cycle costs, and mission impact.
Additional scope of services included:
Establishment of a Ten-Year Capital Construction Program to address all federal mandates and client objectives, specific to energy and water use, further addressing Greenhouse Gas (GHG) emissions, achieving LEED-EB: O&M certifications, and Executive Order 13514.

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.

Setty provided ASHRAE Level II Energy Audit for the below listed buildings at Georgetown Visitation Preparatory School.
Georgetown Visitation Preparatory School was founded in the year 1799 as Georgetown Academy for Young Ladies in Washington, DC. It was also formally referred to as the Convent and Academy of the Visitation. The oldest Catholic girls’ school in the original thirteen United States, it has grown and flourished for over 200 years.
