Audits
Energy audits are comprehensive evaluations of the actual performance of a building’s energy using systems.Audits are a launching point for many other energy services. After an audit is completed, the utility can match the customer’s needs with available utility programs.
To Reduce Watt and/or Watt-hour
First and foremost, we need to understand it!
Audit services may provide any or all of the following:
• A comprehensive analysis of energy costs• Breakdown of energy use by applications/pieces of equipment
and processes • Recommendations for energy efficiency measures• Load management suggestions• Estimated implementation costs and cost-to-benefit analysis• Available rates, rebates and financing options• Information on available technical assistance• An educational opportunity to the customer
