Commercial Building Energy Audits

The University of Dayton Building Energy Center (UD-BEC) provides low-cost energy audits of commercial buildings.

The three steps for each energy audit are:

· Client provides energy bills and base data on building and equipment at least two weeks prior to site visit. UD-BEC team analyzes data prior to site visit.

· UD-BEC team visit the site for one or two days depending on building size.

· UD-BEC team delivers confidential report within four-weeks of site visit.

UD-BEC commercial building energy audit reports include:

· Building Description

· Energy Using Equipment Description

· Statistical Analysis of Electricity and Natural Gas Use

· Benchmarking Comparison of Building’s Energy Use to Similar Buildings in Region

· CO₂ Footprint Analysis and Information on Purchasing Wind Energy

· Hour-by-Hour Energy Simulation Model Calibrated to Baseline Energy Use

· List of Specific Energy Savings Opportunities (ESO). Each ESO includes:

o Specific Recommendation

o Estimated Savings

o Estimated Implementation Cost

o Estimated Simple Payback

· General Advice on Quantifying Energy Efficiency Opportunities

· ETracker Software for Tracking Weather Adjusted Energy Savings from Utility Bills

Energy costs for commercial buildings are about $2.00 per conditioned square foot per year. The cost for a UD-BEC assessment is generally about $0.10 per conditioned square foot of floor area.
