Energy Auditor

Energy auditors help identify ways homes and businesses can save money and reduce environmental impact. They inspect buildings, analyze energy use, and recommend improvements for heating, cooling, and lighting systems. Energy auditors blend construction knowledge, building science, and technology to measure energy efficiency. They often work with utility companies, contractors, or sustainability consultants to improve performance and lower costs.

What Energy Auditors Do

Energy auditors evaluate how efficiently a building uses energy and identify cost-saving opportunities. They use diagnostic tools to detect air leaks, insulation gaps, and inefficiencies in HVAC systems and appliances.

Responsibilities

• Conduct on-site inspections and collect building data
• Use blower doors and infrared cameras to test energy performance
• Review utility bills and analyze consumption patterns
• Recommend upgrades for lighting, insulation, and HVAC systems
• Prepare reports summarizing findings and recommendations

Skills and Traits for Success

• Knowledge of building systems and HVAC principles
• Analytical and problem-solving ability
• Familiarity with diagnostic tools and energy modeling software
• Attention to detail and safety awareness
• Communication skills for explaining recommendations to clients

Work Settings

• Energy efficiency consulting firms
• Home performance contractors
• Utility and government weatherization programs
• Environmental and engineering firms
