Which of the following is a common outcome of successful energy audits?

Successful energy audits are designed to identify opportunities for improving energy efficiency within a facility. When an energy audit is conducted effectively, one of the most common outcomes is the implementation of improved energy efficiency measures. These measures can include upgrades to lighting systems, HVAC improvements, insulation enhancements, and more efficient operational practices, all of which work together to reduce energy consumption.

By focusing on energy efficiency, facilities can lower operational costs, reduce environmental impact, and often increase the lifespan of equipment by ensuring it operates under optimal conditions. This outcome directly correlates with the findings of the audit, as the objective is to identify both wasteful practices and potential enhancements that can lead to more sustainable energy use.

The other options do not align with the intent of energy audits. Higher equipment inventory does not inherently relate to energy management, increased utility bills contradict the goal of reducing energy use, and more frequent equipment failures would suggest poor maintenance or operational practices, which energy audits aim to improve.
