How many times has the word “audit” been used in the wrong connotation? Everyone hears the stories of having their taxes audited and the nightmare of working with the IRS. So naturally, when mentioning the “word” to facilities management, the first reaction is horror and disgust followed by, “We’d rather just not pursue that route right now.” So what are you actually losing by neglecting your energy usage? Is it best to wait until your manager or a new tenant forces you to expose your energy bill? How much time does a facility owner or manager have to dedicate to an audit to substantially reduce energy?

The first step to subverting fear about an energy audit is to understand the process and terminology –  which can be initiated by discarding the term “audit” in place of “Energy Analysis.”  Typically, the actual Audit portion of the project is at the end to quantify measures found in an Assessment of your building. The three components of an Energy Analysis include:

          1. Energy Benchmark -
  1. Assessment -
  1. Audit –

Energy Analyses (a.k.a."audits”) have traditionally received mixed reviews among stakeholders in the facilities industry. Figure: 1 illustrates common facts and myths that are often associated with energy analyses with facilities staff. The most common myths are centered on the cost and complexity of an analysis that has the ability to produce a ROI (Return on Investment) less than five years. The process of an Energy Analysis (BenchmarkAssessment, and Audit) allows an owner or tenant to pursue savings based upon their budget and their level of engagement. For example, a facility with a relatively low Energy Star Building Index (> 50) can typically save up to 20% without actually quantifying the saving measures in the Audit portion of the analysis. A significantly low score could suggest failed equipment or poor method of control – Both of which lead to higher savings after a full Assessment.

Other myths include false expected savings, or no savings at all, generated by an analysis that may cost thousands of dollars and hundreds of staff hours to produce. Therefore, isn’t it easier to skip the analysis if you sign a service contract that guarantees your equipment is working correctly? Aren’t most of the saving measures generated centered on broken equipment? Mechanical maintenance serves to protect capital investments and tenant comfort by keeping equipment functioning properly. In the energy analysis process, the Assessment will identify failed components, but more interestingly, suggest a new methodology for controlling existing equipment; Methodology typically requiring little upfront cost.

Now that the fear of the term “audit” has subsided, what level of financial involvement does the customer have when compiling a report? As identified above, the analysis itself as well as the measures it produces, can all be scaled based upon budget. Cost to generate a report is inherently a measure of facility size and usage requirements by the tenant. A facility that runs 24/7 is more likely going to have a higher level of involvement from the energy contractor and the maintenance staff to reduce energy. These facilities tend to be more critical in nature, with suggested energy measures typically requiring the upgrade of equipment and scheduled shutdowns. On the contrary, general usage spaces such as offices require less staff involvement for the analysis and little tenant disruption for most energy saving actions.

Energy consumption within buildings is characteristically undervalued as a profit driver and funneled into expected annual costs. Negligently signing an energy bill is typically easier than trying to actively understand and reduce consumption. So how does energy stack up against other assumed costs in an occupied building? We can observe Figure: 2 to see where your consumption fits into the rest of your budget –  which is larger than expected.

Although this example is relatively vague, it shows that a mere savings of 18% in a building this size equates to a much larger savings –  this disregarding upfront capital savings from a provider. Many energy upgrades typically placed into capital avoidance budgets can surface in an Assessment and be quantified in an Audit with expected returns.

The term “audit” has gained popularity in the energy industry due to its effectiveness at evaluating and quantifying consumption. Facility owners and managers are pursuing savings as tenants are demanding Energy Star and LEED ratings of a building before signing a lease. Partnering with a contractor to complete an energy analysis good practice and helps to alleviate concerns and provide reasonable expectations on savings.
