Energy Audits Level 1

Energy Audits Level 1

Preliminary Energy Assessment Consists of spending up to a half-day onsite identifying energy saving opportunities, interviewing facility personnel, and reviewing utility bills.
Clients receive a report that aids in determining where to apply energy savings efforts, to include decisions on retro/re-commissioning or which buildings to apply more intensive auditing methods. It does not provide details such as engineering estimates of energy savings, project costs, or project payback. The Preliminary Assessment serves as a roadmap that facilities utilize to improve energy efficiency and reduce operating costs. ASHRAE Level 1 Audits include a cursory analysis of energy bills and a brief survey of the building to produce a rough estimate of how efficiently energy is used in the building. This level of effort will detect at least some of the “low-hanging fruit” and may indicate other options worthy of more study, but is not considered comprehensive.

    Energy Audits Level 2

    Energy Audits Level 2

    Includes a more detailed building survey and energy efficiency study of capital intensive components.
    By investing more effort in the building survey and energy analysis and by adding in some system performance testing, this method provides a breakdown of how energy is used in the building as well as a broader range of savings options, including simple capital investments. It accounts for people and their effect on uncertainty of savings, and also explores maintenance procedures and assesses any impacts savings measures may have on them. For each Energy Conservation Measure (ECM), it provides the energy and cost savings, cost of the measure, and payback period. Recommendations on changes to operation and maintenance procedures are also included. In many cases, this level of analysis can be sufficient.

      Energy Audits Level 3

      Energy Audits Level 3

      Also known as the “investment-grade audit”, this analyzes any large capital projects you may be considering as a result of previous, simpler audits.
      Detailed data is gathered from field equipment, extensive test measurements are taken which may include spot-measurements and short-term energy monitoring, possible risks are assessed, and intensive engineering and economic analysis produces reliable estimates of project energy and financial performance with the high confidence needed for major capital projects. Typical candidates for an IGA are facilities whose electric demand exceeds 200 kW. Often this level of audit is required to procure funding for initially expensive or high risk ECMs.
