Energy Audits
This is first step to determining energy usage is Energy Benchmarking. A base line energy profile will be developed illustrating how your facility compares to other like facilities and how it compares to energy efficient facilities of like structure and use.
ASHRAE Level I - Walk-through Analysis
A Level I audit includes the preliminary energy use analysis described above, but also includes a site visit by a CES engineer and a report detailing low-cost/no-cost measures and potential capital improvements for further study. An ASHRAE Level I audit also satisfies one of the pre-requisite requirements for the USGBC’s LEED for Existing Buildings: Operations and Maintenance.
ASHRAE Level II - Energy Survey and Analysis
A Level II audit includes the preliminary energy use analysis and ASHRAE Level I analysis, but also includes more detailed energy calculations and financial analysis of proposed energy efficiency measures. The financial analysis or Life Cycle Analysis allows the facility owner to truly understand the financial benefits of installing energy efficient measures. An ASHRAE Level II audit can also earn additional points for LEED for Existing Buildings: O&M.
ASHRAE Level III – Detailed Analysis of Capital-Intensive Modifications
A Level III analysis is a further expansion from the previous levels of effort and is based on the facility representative’s selection of measures to analyze further. This may include further refinement of an energy model or more extensive data collection.
