Level 2 Energy Audit

The level 2 audit balances the need for engineering rigor with the need to keep auditing cost effective.

Level 2 energy audit.

A level 2 audit includes the preliminary ashrae level 1 analysis but also includes more detailed energy calculations and financial analysis of proposed energy efficiency measures. In addition a level 1 audit a level 2 audit includes the following. Which includes calculated tables outlining building energy use and energy efficiency measures audit data report may be submitted to cities to. The level 2 audit starts with the findings from the level 1 audit and examines the building energy systems in detail in order to define a number of potential energy efficiency improvements.

Level 2 energy survey and engineering analysis. Capital improvement and operation and maintenance budgets are key funding sources for energy audits. The following list is a brief description of the steps performed for the level 2 audit. Funding an energy audit the scope and level of detail of the energy audit can be a big driver in costs.

The level 2 report details the opportunities to such a degree that actual decisions on implementation can be made and the leed eb credit can be realized. Ashrae level 2 energy audit process. Level 1 walk through analysis. The financial analysis or life cycle cost analysis provides the facility owner with comprehensive understanding of the financial benefits of implementing specific.
