A professional home energy audit can reveal where a house is wasting energy—and where improvement dollars may have the greatest impact. Learn how energy auditors use blower door testing, thermal imaging, insulation inspections, HVAC analysis, duct testing, utility data, and modern building-performance technology to identify opportunities to lower energy costs while improving comfort and home performance.

A professional home energy audit can uncover hidden air leakage, insulation deficiencies, HVAC inefficiencies, duct problems, and other conditions that drive up utility costs. Learn how energy auditors use diagnostic testing and building science to identify opportunities for improvement—and how BPMS™ helps professionals turn those findings into clear, actionable recommendations for homeowners.

A home energy audit is a comprehensive evaluation of how a house uses, loses, and manages energy. From blower door testing and thermal imaging to insulation, HVAC, ductwork, moisture, appliances, and utility analysis, learn what professional energy auditors inspect, what the results mean, and how modern building-performance technology such as BPMS™ is transforming the energy-audit process.

document more, communicate better, manage crews, capture field data, produce professional proposals, invoice accurately, and still deliver exceptional work. Yet many businesses continue running on paper forms, spreadsheets, text messages, disconnected apps, and manual processes. Discover why better contractor software is becoming essential—and how an integrated platform like BPMS™ can transform building-performance, HVAC, energy-auditing, and home-performance businesses from the field to the final invoice.

Air leakage is one of the most common—and most misunderstood—causes of high energy bills, uncomfortable rooms, moisture problems, and poor HVAC performance. This complete guide explains how air moves through a home, where leakage occurs, how energy auditors measure it with blower door testing and ACH50, how to diagnose leakage pathways, and how modern tools like BPMS™, BPMSField™, BPMS Thermal™, BPMS LiDARScan™, and BPMS Intelligence™ help professionals turn invisible air movement into actionable building-performance data.

Energy auditing is evolving from a specialized inspection service into a technology-driven building-performance profession. As homeowners, contractors, utilities, weatherization programs, and building owners seek greater efficiency, electrification, better indoor comfort, and measurable energy savings, skilled energy auditors are increasingly positioned at the center of the transition. Explore the career outlook, income opportunities, certifications, skills, technology, business opportunities, and future of the professional energy auditor.

Whether you’re a new energy auditor or an experienced building performance professional, following a structured audit process is essential for delivering accurate diagnostics and valuable recommendations. This comprehensive guide walks through every phase of a professional home energy audit—from customer intake and safety inspections to blower door testing, thermal imaging, combustion safety, HVAC evaluation, insulation assessment, and final reporting.

Building science explains how heat, air, moisture, pressure, HVAC systems, occupants, and the building enclosure interact to determine how a home actually performs. This complete guide gives energy auditors, HVAC professionals, weatherization specialists, contractors, and homeowners a practical understanding of building-science fundamentals—from heat transfer and air leakage to insulation, blower door testing, thermal imaging, ventilation, moisture, HVAC loads, and the emerging technologies changing building performance.

Traditional energy audit software helped move the industry away from paper forms and spreadsheets, but today’s building performance professionals need much more. Explore how BPMS™ approaches energy auditing as a connected business and building-performance workflow—bringing field data, diagnostics, thermal imaging, LiDAR, load calculations, reporting, work scopes, proposals, invoicing, and emerging heat-flux technology into one ecosystem.

Energy conservation did not begin with solar panels, smart thermostats, or modern energy audits. For centuries, people have adapted buildings and technology to use available energy more effectively. This guide traces the evolution of energy conservation from early passive building practices and industrialization through the 1970s energy crisis, the creation of the U.S. Department of Energy, weatherization, ENERGY STAR®, modern building science, renewable energy, and today’s data-driven building performance technologies.

Learn how blower door testing measures air leakage, helps locate hidden drafts, supports energy audits, and guides effective air-sealing improvements. This complete guide explains the equipment, testing process, results, safety considerations, common mistakes, and how BPMS™ helps energy professionals document and manage blower door testing workflows.

Air Changes Per Hour (ACH) is one of the most important measurements in residential building performance. It tells energy auditors how often the total volume of air inside a home is replaced over the course of one hour and provides valuable insight into air leakage, energy efficiency, comfort, indoor air quality, and HVAC performance. This guide explains what ACH is, how it is measured, how it is calculated, applicable standards, and how energy auditors use ACH results to develop meaningful recommendations.

Weatherization has transformed millions of homes by improving energy efficiency, reducing utility costs, and increasing comfort for families around the world.
