ENERGY ASSESSMENT
    e2build sets the metrics to compare the building’s energy use against comparable buildings or mathematical models to examine its operating performance.
      The Level 1 energy assessment identifies rough potential for energy savings in the facility, including high level benchmarking and list of recommended energy efficiency measures (EEMs). Level 2 includes information from the Level 1 and providing site-specific analyses and recommended EEMs and return on investment (ROI). The Level 2 energy assessment includes communication with facility staff, drawings review and perform a detailed building survey. The Level 3 assessment is expended Level 2, including cost estimates. The analysis is expanded through measurements and modeling. Main goal is to reduce investment risk by increasing accuracy around costs, savings and ensuring projects feasibility.
        e2build provides reports for Level 1, Level 2 and Level 3 including but not limited to:
        LEVEL 1
          > Brief, walk-through the building
            > Building energy benchmark, estimating total building energy use and comparing to similar buildings.
              > High-level definition of energy system optimization opportunities
                > Qualitative EEMs describing savings, costs and priorities as low, medium or high.
                  > Outline applicable incentive programs
                    > Recommendations and qualification/applicability for Level 2 assessment
    LEVEL 2
      > Detailed building survey of systems and operations
        > Building benchmarking presenting in energy use intensity (EUI), which expresses total building energy use per building area per year.
          > Breakdown of energy source and end use identifying EEMs for each energy system
            > Compares total energy use to ideal/theoretical energy model of the building and business, based on applied science, except for complex production systems
              > Quantitative EEMs with detailed, savings, costs (no-cost, low-cost and high-cost) and economics including applicable incentive programs.
                > Recommendations and qualification/applicability for Level 3 assessment
                LEVEL 3
                  > Whole-building, expanded analysis, mathematical model simulation calibrated with field data and measurements
                    > Longer term data collection and analysis
                      > Accurate modeling of EEMs and energy response
                        > Compares total energy use to ideal/theoretical energy model of the building and business, based on applied science including complex systems, plant processes and economics.
                          > Construction cost estimating, investment-grade, decision-making and applying for incentives support.
