ENERGY MANAGEMENT

PREDOMINANT ENERGY USE STUDIES:  Gerald Spencer, P.E. has 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 15 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. 

LIFE CYCLE COST ANALYSIS & ENERGY MANAGEMENT:  Gerald Spencer, P.E. has 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.  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. 

1.   COMPUTER PROGRAMMED ENERGY CONSUMPTION MODELING:  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.

2.   KVA DEMAND CHARGE REDUCTION:  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.

3.   INCANDESCENT LIGHTING:  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.

4.   LIGHTING LEVELS:  Gerald Spencer, P.E.  will review lighting levels in the site and justify any levels that are greater than the minimum requirement.

5.   INSULATION:  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.

6.   WINDOWS:  Gerald Spencer, P.E. always considers the following glass options:

6.1.    Different Reflective coatings

6.2.    Double pane insulating glass

7.   DESIGN THE BUILDING WITH LESS 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.

8.   REVIEW OPERATIONAL PROCEDURES:  Review temperature settings, operational hours, manpower requirements, and all other .

9.   REVIEW MAINTENANCE PROCEDURES:  Review expenditures, procedures, and schedules for maintenance.

10. AUTOMATION:  Provide automation for resetting of space temperatures with the use of programmable thermostats.

11. HEAT RECLAIM:  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.

12. TREES FOR WINDOW SHADING:  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.

13. OTHER UTILITY COST SAVINGS:  We will discover other areas that utility cost savings are possible when we get into this project.  These items will also be evaluated.

14. ECONOMIC ANALYSIS:  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.

14.1.    CAPITAL EXPENDITURES:  Each proposed change to the facility will be evaluated 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.

14.2.    OPERATION AND MAINTENANCE CHANGES:  Operations and Maintenance changes to the facility will also be evaluated on a Life Cycle Cost basis to determine the economic viability of each proposed change.

14.3.    ECONOMIC EVALUATION CRITERIA EXPERIENCE:  We are familiar with the Army and NASA economic criteria and guidelines for evaluating the various proposals for the modification of existing facilities.

14.4.    ECONOMIC EVALUATION CRITERIA:  We will work in cooperation with the USAF accounting department and other departments as required to develop economic criteria and guidelines for evaluating the various proposals for the construction of these new facilities.
