Level II- Energy Survey and Analysis: This includes a more detailed building survey and energy analysis. A breakdown of the energy use within the building is provided. A level II energy analysis will identify and provide the savings and cost analysis of all practical measures that meet the owner’s constraints and economic criteria, along with a discussion of any changes to operation and maintenance procedures. It may also provide a list of potential capital-intensive improvements that require more thorough data collection and engineering analysis, and a judgment of potential costs and savings. This level of analysis will be adequate for most buildings and measures.
Level III –Detailed Analysis of Capital-Intensive Modifications: This level of engineering analysis focuses on potential capital-intensive projects identified during the Level II analysis and involves more detailed field data gathering as well as a more rigorous engineering analysis. It provides a detailed project cost and savings calculation with a high level of confidence sufficient for major capital investment decisions.
RAS performs three levels of energy audit per ASHRAE Standards:
Level I – Walk-Through Analysis: Assess a building’s energy cost and efficiency by analyzing energy bills and conducting a brief on-site survey of the building. A level I energy analysis will identify and provide a savings and cost analysis of low-cost/no-cost measures. It will also provide a list of potential capital improvements that merit further consideration, and an initial judgment of potential costs and savings.
