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:
Department of State, Bureau of Overseas Buildings Operations, Leased Swing Space|
Building Automation System | Jakarta, Indonesia
Setty provided MEP and integrated controls design services to prepare drawings, specifications and Construction Administration services for the Department of State. Their Bureau of Overseas Building Operation (OBO) leases building space in foreign countries, which includes this 19 story building with two levels of parking garage. The U.S. Embassy in Jakarta will occupy several floors, which includes Compound Access Controls, guard booths, motorized gates and barriers, security systems and other security related infrastructures.
Scope of services included:
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.
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.
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:
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.
DC Government Public Works Department | Direct Digital Control Master Plan |
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:
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.
National Institute Of Standards & Technology (NIST) | BACNET Master Plan |
Setty is developing a Master Plan Report for the installation of a BACnet Central Control and Monitoring System (CCMS) for Phase I, which encompasses heating, ventilating and air conditioning systems in the main administration building, as well as 18 research laboratory buildings on campus.
Phase II covers the design of the DDC Control System for Building 220, and its connection to the master control system.
Scope of services included:
GSA: New U.S. Federal Courthouse | HVAC Controls
+ Total Building Commissioning | Billings, MT
Setty performed total building commissioning of HVAC, Electrical, Plumbing, Fire Protection, building enclosure, and related building systems for the new courthouse. Commissioning was incorporated from early concept design to the post-construction phase of the project, to ensure delivery of a high performing building.
The 146,742 gsf courthouse was designed to include courtrooms, judicial chambers, the U.S. Marshals Service (USMS) holding cell areas, administrative areas for the U.S. District Courts, the U.S. Magistrate Court, Probation Court, the U.S. Attorney’s Office, and the General Services Administration (GSA).
Scope of services included:
Earned Design-Build Institute of America's Design-Build Honor Award.
Federal Office Complex (FOC) Headquarters Compound | Central Plant Utilities
Analysis and Review | Undisclosed Location
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:
