Gerald Spencer, PE is has designed many Data Acquisition systems over the past 25 years, including the 16,000 Point (24,000 point capacity) Distributed Control System (DCS) for the chamber operations at Building 32, NASA Johnson Space Center. This is the large space simulation chambers A (the largest in the world) & B. This is a stand-alone info-highway for test data acquisition, test data logging, space simulation systems control, space simulation systems monitoring, cryogenic systems control, solar simulation systems control, helium refrigeration systems control, and cryo-pumping systems control.
Gerald Spencer, PE completed the week long Corps of Engineers Energy Management Control Systems (EMCS) Design Course in Huntsville, Alabama in the spring of 1992. Gerald Spencer, PE recently completed the Programmable Logic Controller (PLC) and Distributed Control System (DCS) training classes taught by the Instrument Society of America (ISA) Instrument Technology Training Program (ITTS). The ITTS classes were addressing systems of 2,000 points. SDJ&S has completed the replacement design of the NASA Man Rated Space Chambers “A” & “B” Instrumentation and Control System with a new 15,000 point system served by multiple host Central Processing Units (CPU), remote stand alone Programmable Logic Controller (PLC) control/communication modules, multiple remote I/O modules, and dual data transmission medium data highway. We are leaders in instrumentation design but attend these courses not to learn, but to keep our design nomenclature similar to the evolving nomenclature in the control & instrumentation industry.
The Supervisory, Control and Data Acquisition (SCADA) systems and Utility Control Systems (UCS) is the current nomenclature for EMCS systems that control utilities in addition to the Traditional HVAC and Lighting systems controlled by EMCS systems.
Building Information Control Systems such as life safety, intrusion detection, closed circuit TV security monitoring, door control, and fire safety can be integrated into the UCS, but the life safety fire detection/control must usually stand alone in order to meet the requirements of NFPA codes.
We review temperature settings, operational hours, manpower requirements, and all other operational procedures and rules.
Review expenditures, procedures, and schedules for maintenance.
Provide automation for resetting of space temperatures with the use of programmable thermostats.
We will evaluate waste heat reclaim systems addition to the existing equipment. Auxiliary condensers added to condensing units can be used to generate domestic hot water.
We will consider the addition of trees that are located to shade the windows during the summer, to reduce the solar load on the windows.
We will discover other areas that utility cost savings are possible when we get into this project. These items will also be evaluated.
Each proposed change to the facility will beevaluated on a Life Cycle Cost basis to determine the economic viability of each proposed change. Each proposed change must stand alone on it’s own economic merit.
We always try to minimize the use of incandescent lighting by substituting florescent (or HID) lighting to provide the same lighting levels with less wattage of energy usage everywhere possible.
Gerald Spencer, P.E. will consider different thickness’ of Roof Insulation and Wall Insulation if economic life cycle cost analysis can justify the capitol expenditure.
Gerald Spencer, P.E. will review lighting levels in the site and justify any levels that are greater than the minimum requirement.
Gerald Spencer, P.E. always considers the following glass options, different reflective coatings, and double pane insulating glass.
We do not wish to detract from the exterior or interior aesthetic appearance of any facility. It would of course save energy to not provide any windows at all, and have only insulated walls, but the morale of the personnel would be reduced, and the personnel productivity would also be reduced. We will provide architectural aesthetic opinions of the effect of any proposal that effects the visual appearance of the facility or that affects the habitable quality of any facility.
Gerald Spencer, PE can provide design for automation for load shedding as required to reduce KVA demand charges by the power company. This will require a system to monitor the KVA demand at the incoming electrical service with pulse meters that will constantly up-date a controller as to the present KVA Demand that is the basis for the electrical demand billing. This Controller will cycle various loads off for relatively short periods of time so that the total measured demand at the point of metering is reduced. The various loads will each receive a priority rating and the controller will selectively cycle the various loads at different times as required to reduce KVA Demand. This can be a part of the EMCS, SCADA, or UCS system.
Gerald Spencer, P.E. provides life cycle costs of each option for the purpose of decision making for system selection. Additional construction costs would be sometimes serve our clients better in a savings deposit rather than invested into more efficient energy consumption systems.
Gerald Spencer, P.E. has personal experience preparing energy consumption analysis of energy used exploring for, producing, or transporting, a material extracted from the earth; existing energy used for manufacturing real goods; and/or processing tangible personal property for sale as tangible personal property for use in obtaining Texas State Sales Tax Exemptions and Rebates. Gerald Spencer, P.E. has prepared more than 25 Predominant Energy Use Studies in the past 20 years. We are familiar with the Rules and regulations of the Texas State Comptrollers Office. We have recently (July 2003) completed a Predominant Energy Use Study for a 40.8MVA - 138KV substation for a local client that resulted in a multi-million dollar state sales tax refund.
Gerald Spencer,P.E. has personally prepared more than 200 energy consumption analysis of federally-funded construction projects since 1968 in accordance with Energy Life Cycle Cost Analysis principals that comply with the DoD, GSA, DOS, and NASA guidelines where we were the Architect Engineer of record or the Engineer Of Record (EOR) for the design of the construction project. Gerald Spencer, P.E. is familiar with the DoD Criteria, NASA-JSC Construction Criteria, Corps of Engineers Technical Manuals, Department of State Design Guidelines, General Services Administration, U. S. Postal Service, plus other rules and regulations governing energy management. Gerald Spencer, P.E. has prepared mote than 80 formal computer generated Energy Consumption Analysis Reports for documentation proving compliance with ASHRAE 90 since 1980. Gerald Spencer, P.E. has prepared reports and analysis of proposed buildings to indicate compliance with ASHRAE 90.1 in accordance with the requirements of the Texas Energy Code. Prior to that Gerald Spencer, P.E. prepared hand calculated energy consumption analysis for many facilities including the FBI academy 1965 at Quantico, Virginia; Federal Courthouse and Office Building, San Antonio, Texas 1965; FAA control tower and TRACON facilities at DFW airport, Texas 1971; plus several commercial and privately funded reports for non-federally funded projects. These reports compared various HVAC systems on a Life Cycle Cost Analysis (LCCA) basis to determine the most cost effective system to be constructed for each facility. These reports take into consideration all capital investment, operating costs, taxes, interest, maintenance and replacement costs on a life-cycle cost analysis basis. Gerald Spencer, P.E. also considers small subsystems such as adding capacitors to motors for power factor improvement and demand charges reduction. We have in-house capability and experience in preparing energy budgets and energy analysis by computer modeling. Gerald Spencer, PE is experienced in the design of all types of energy management systems that control the cycling of energy consuming equipment according to a preset program for the optimum use of energy. Often a project will require the preparation of a formal report to economically justify the expenditure of funds for improvements or for new construction. This report is used to justify and defend the design decisions. Gerald Spencer, PE always approaches energy engineering with an open mind, and evaluate every conceivable energy savings option.
Gerald Spencer, PE provides energy consumption calculations by computer modeling each building that is planned. Once we have this data inputted into our computer, we can easily ask "WHAT IF” questions concerning not only the equipment selection, operation, and configuration, but also questions concerning the construction or modification of the building. We can provide a computer programmed energy consumption simulation model for any building using our in-house computer. Existing Projects that have records of utility consumption and costs will allow us to vary the inputs of lights, people, and other variables until the energy consumption matches the historical data from the utility billings for a very accurate projection of future energy consumption with any proposed modifications. This will allow us to ask “WHAT IF” questions, and get finite energy savings in BTU, KWH, KVA, from any and all proposed energy related modifications to the building. Typical proposed considerations will be in the following areas, plus others that we think of when we get into the project.
