An ASHRAE “Level II – Energy Survey and Analysis” includes a more detailed building survey and energy analysis than the cursory Level I. A breakdown of energy use within the building is provided. A Level II energy analysis identifies and provides the savings and cost analysis of all practical measures that meet the owner’s constraints and economic criteria, along with a discussion of any effect on operation and maintenance procedures. It also provides a listing of potential capital-intensive improvements that require more thorough data collections and analysis, along with an initial judgment of potential costs and savings. This level of analysis will be adequate for most buildings and measures but is less comprehensive than Level III, which includes more detailed analysis often with annual hourly load computer modeling.
