ENERGY AUDITS

Energy Audits

We Conserve Energy. We Preseve Jamaica.

NESol in its new role as an energy solutions provider is seeking to facilitate an acceleration in the use of renewable energy in government agencies and industry in order to engender improved operational efficiencies and productivity. A prerequisite to the implementation of an energy solution is the conduct of an energy audit.

An energy audit is an inspection, survey and analysis of energy flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s). When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings.

NESol anticipates an increased demand for energy audit as businesses seek to move towards sustainable energy future. This is against the background of the need to lower expensive energy costs which have had a debilitating effect on business productivity and profitability.

In furtherance of this strategic thrust, NESol proposes to re-engineer your facilities with a view to bring down the energy costs significantly and eliminate the inefficiencies associated with the use of incandescent and florescent lamps coupled with lack of special tints on glass windows.

The re-engineering process is proposed for two phases. Phase 1 will entail Energy Audit and Assessment of all facilities while Phase 2 will entail the implementation of solar energy solution at the facility (ies)

Scope of Services

Site Visits/ Data Collection

To properly evaluate all facility process and HVAC systems, NESol will perform a detailed review of facility equipment and systems with staff, collect energy usage and equipment data, and develop cost savings recommendations. The site visit(s) will include the following:

  • Detailed facility review with plant operator.
  • Collection of equipment nameplate data.
  • Performing equipment efficiency tests on large equipment. This may include pressure, flow and electrical measurements.
  • Installation of data loggers on selected equipment as needed to develop equipment use profiles.

The NESol will require that each institution provide the following information to facilitate the review:

  1. i. Facility O&M manuals & plant drawings.
  2. ii. Specification data for all major equipment (i.e. pumps curves, performance data).
  3. iii. Any recent engineering facility evaluations/reports.
  4. iv. 12 months of facility operating reports (if available)
  5. v. 12 months energy bills (electric and fuel for generator if any)
  6. vi. A schedule of the events/activities that took place at the facility over the last year.

Energy Analysis and
ReportDevelopment

The energy analysis that will be effected by NESol will include the following tasks:
Review Energy Use and Rates:

  1. a. Energy billing evaluation of facility energy use
  2. b. Rate structure evaluation
  3. c. Alternative energy generation procurement options
  4. d. Evaluation of demand response programs

Energy Balance

The Energy balance is designed to determine how energy is used within the facility. NESol will develop an energy balance of the facilities. This will include the following tasks:

  • Develop inventory of all energy use equipment grouped by process
  • Use a portable power meter, data loggers and available SCADA data to verify energy use and hours of major equipment.
  • Comparison of energy balance with annual energy bills to verify data.
  • Develop fuel oil energy balance to benchmark facility process systems.
  • NESol will utilize appropriate tools to benchmark the efficiency of the various facilities.

Pump Systems Evaluations

This may not be applicable to all customers. However since pumping equipment is significant energy user at pools, NESol’s pump equipment testing will include the following:

  • Collect field data for each pump that includes flow, suction and discharge pressure and a power measurement (amperage and/or kW measurement) to determine pump operating point.
  • Determine the system static head value to develop pump system curves.
  • Compare existing pump system operation with the original design parameters.
  • Compare existing efficiency with other pump manufacturers.
  • Review pump efficiency improvements such as pump replacement or rebuilding.
  • Evaluate the potential savings of installing variable frequency drives and premium efficiency motors.
  • Evaluate hydraulic and operational improvements that may improve efficiency.

Process Systems Evaluations

Each Customer is expected to provide operational data to enable NESol to evaluate the efficiency of each facility process system. Analysis will include:

  • Benchmarking each process system based on facility process flows and loads.
  • Use of process models to evaluate potential energy saving improvements.
  • Evaluation of potential alternatives to technologies currently in use at the facility for each process (for example improved DO monitoring, SCADA, substitution of fine or ultra-fine bubble aeration, dewatering and solids management alternatives.

Energy savings for process measures shall be based on facility’s previous 12 months of operating data.

Cost/Benefit Analysis

Proposed energy saving projects will include:

  • Conceptual cost estimate based on industry data and quotes from manufacturers.
  • Detailed energy saving calculations that include baseline development from SCADA data, instantaneous electrical measurements, equipment performance curves and data loggers to determine how equipment energy use varies.
  • Identification of renewable energy solution with estimated cost of procurement and implementation.

Fees for Energy Audit

Our fees are the best on the market. The fees will depend on a number of factors including the building size and the number of electrical equipment being used. Come and have a talk with us and we will work out a financial plan that is affordable.

PROJECTED TIMETABLE

NESol is projecting the following for the energy Audit:

Facility Date

Preparation
and Submission
  Weeks Weeks Weeks Weeks
Building 1 4 4 2 2

For each additional building NESol may run the audits concurrently. It must be understood that NESol will utilize power meters and Data loggers to obtain information from equipment. The data loggers will be affixed to each item of equipment for up to four weeks hence the timeframe noted above. The use of SCADA systems in conjunction with the JPS will also be time consuming i.e. observing live data over a period of four weeks. NESol will utilize thermal meters to test insulators and temperature metres to test the efficiency of air conditioning units.
