Energy audits are invaluable in comparing a building’s current resource consumption to that predicted by its original design or against facilities with similar operations. These audits are presented in a report that summarizes short- and long-term action plans, energy-efficiency measures, associated costs, potential savings, and recommendations.
What is involved?
Pre-Audit – Having familiarity with a building’s history is integral to a successful energy audit. The building’s energy consumption rate stems various parameters, including weather patterns, energy sources, load factors, maintenance practices, and equipment age. Reviewing prior audits, in conjunction with an examination of energy consumption levels and patterns over a two to three year period, can also help further understanding of the specific building prior to engaging in a complete investigation. BLUE’s focus on low- & no- cost operations and maintenance issues is meant not only to address client-specific needs, but also to determine and implement the strategy promising the greatest benefits and reductions.
Site Visit – A site visit is made only after gathering all required information and determining the specific needs of the building owner. In some cases, an off-hours visit is warranted to check whether or not the systems are turned down or off completely. Data is collected throughout the site visit and inspection of building envelope, equipment, and systems is performed. A variety of parameters are checked, including but not limited to the building’s combustion efficiency, lighting levels, air velocity, humidity, and various area’s temperatures.
Analysis – After completing the site visit, BLUE analyzes the results, segregates energy consumption into a base load and a weather dependent load, and uses applicable rates in the deliberation of potential savings, thereby allowing for seasonal and time-of-use discrepancies. Life cycle costs are then analyzed and calculated to include the initial equipment cost, energy use reductions, and applicable maintenance savings. BLUE develops an integrated package of reduction measures that align with the building’s energy use and client’s financial goals.
Report – BLUE will provide a report summarizing the auditing process, assumptions made, as well as the short- and long-term action plans. The report will highlight specific energy efficiency measures, associated costs, potential savings, and summary of the building’s historical energy consumption intended to stress current conditions and emphasize recommendations for the future.
