Commercial Energy Audits

For commercial and industrial buildings, we carry out a detailed Commercial Energy Audit for the building. Codex Energy have registered SEAI Energy Auditors who can carry out energy audits to comply with SI426 requirements. This typically includes the following:

Building Envelope Analysis

  • Review Architectural drawings and specifications (if available)

  • Inspect building elements on site using the latest thermal imaging technology, to include the following:

    • Insulation of external walls

    • Insulation of roofs

    • Insuation of floors

    • Windows & doors

Mechanical Systems Analysis

  • Review Mechanical drawings, plant schedules and commissioning data (if available)

  • Inspect Mechanical systems on site, to include the following:

    • Air conditioning systems

    • Mechanical ventilation systems

    • LPHW heating systems

    • Domestic hot water system

    • Cold water systems

    • HVAC controls systems

    • Combined heat & power (CHP) systems

Electrical Systems Analysis

  • Review Electrical drawings and equipment schedules (if available)

  • Inspect Electrical systems on site, to include the following:

    • Lighting systems

    • Plant power distribution system

    • Small-power distribution systems

    • Electrical power metering

Utility Bills / Tariff Analysis

  • Examine original basis for Energy Application and tariffs applied

  • Analyse current energy bills.

  • Identify potential savings in energy costs by changing tariffs, energy providers and conditions based upon current energy usage

  • Provide accurate projected annual energy usage costs based upon the revised tariffs

  • Liaise with energy providers to agree new tariffs and arrangements

Commercial Energy Audit Report

The findings from the above items will form the basis of a report which will highlight potential areas of improvement throughout your building with regard to reducing energy usage and running costs. The Energy Audit report will typically include the following:

  • Analysis of the building’s operational profile, hours of use, the number of occupants, etc.

  • Analysis of the building envelope

  • Identify total energy consumption and develop an energy baseline.

  • Identify significant energy users (SEU’s) and establish Energy Performance Indicators (EnPI’s)
  • Utility tariff analysis.

  • Breakdown of energy consuming systems

  • Description and comments on the management, control, and operation of each mechanical and electrical system

  • Recommendations for energy reduction for building envelope, mechanical and electrical systems

  • Feasibility study for renewable energy systems.

  • Cost-benefit analysis for proposed energy reduction initiatives.
