More detailed energy audits (ASHRAE Level 2 and Level 3) provide a comprehensive understanding of the energy usage of building and enables advanced energy efficiency measures and future investment planning. Thank you! An accurate energy audit report is important in keeping energy consumption in check and prolonging the lifespan of electrical equipment. The abstract will be publicly displayed on the jumpintostem.org website. Use iAuditor, the world’s #1 mobile inspection app, to analyze energy consumption habits and recommend steps to reduce energy costs. Thus for shaving off the peak demand supplemental energy measures can be recommended. energy bill analysis, review mechanical and electrical system, building air tightness testing) and many aspects of building (e.g., building envelope, HVAC system, lighting system) to improve the current system for energy efficiency and occupants’ comfort. These potential EEMs, which are identified through detailed energy audits, can be evaluated and prioritized using whole-building energy simulation tools (e.g., EnergyPlus, OpenStudio). Insulation level of the building can be identified based on as-built drawing, while thermal bridging or insufficient insulation can be identified using an IR camera. It also requires the City to make this data public. A successful energy audit must evaluate all of the contributing factors to a building’s energy consumption. Also, the lack of granularity of utility bills reduces the potential for diagnostics and other data processing techniques. It should also indicate the costs and savings for each recommended action, and a priority order for implementation.
