Terms & Definitions Flashcards
Adjusted Baseline Energy
The Baseline Period Energy, modified by Routine and Non-Routine Adjustments, to account for changes in conditions in the Reporting Period or defined normal conditions.
Avoided Energy Consumption
Reduction in Energy Consumption, demand, or related cost that occurred relative to what measured energy (or demand) would have been without the Energy Efficiency Measure, most commonly determined under reporting period conditions. In some cases, avoided energy consumption may be determined under baseline conditions.
Backcasting
Rarely used method of determining Avoided Energy Consumption where reporting period energy is adjusted to baseline period conditions.
Baseline
Referring to (adjective) the systems, time period, energy use, or conditions that provide a reference to which performance of an Energy Efficiency Measure or measures can be compared.
Baseline Adjustment
See Non-Routine Adjustment
Baseline Period
A defined period of time chosen to represent the operation of the facility or system before the implementation of Energy Efficiency Measure(s).
Baseline Period Energy (or Demand)
Energy Consumption (or demand) used within a defined measurement boundary occurring during the Baseline Period without adjustments.
Commissioning
A quality-focused process for enhancing the delivery of a project which includes verifying and documenting that the facility and its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the design intent.
Confidence Level
Confidence level refers to the probability that the quoted range contains the true value.
Demand
A measure of the rate at which work is done or energy is used when applied to a load.
Energy Efficiency Measure (EEM)
An action or a set of actions designed to improve efficiency, reduce energy or water consumption, or manage demand, and sometimes referred to as an Energy Conservation Measure (ECM). In this document, the term EEM may include water, GHGs, energy generation, storage, or other targeted projects.
Energy Consumption
Quantity of energy applied to a load in a specific period of time.
Energy Influencing Factors
Operating conditions that can affect the energy use within a measurement boundary, including static factors and independent variables.
Energy Performance Contract
An agreement between two or more parties where payment is based on achieving specified results, such as improvement in energy performance, reductions in GHG emissions, or energy costs, or the payback of investment within a stated period.
Energy End-Use
Application of energy for a specific purpose which is not the production, transformation, or storage of energy. (Examples: Ventilation, lighting, heating, cooling, transportation, industrial processes, production lines.)
