How EcoAudit® RES Works

A Guided Residential Energy Audit Without Starting From Scratch

Traditional home energy audits often begin with a professional traveling to the property to collect information the homeowner may already know. EcoAudit® changes the starting point by guiding the homeowner through organized data collection before engineering review and field verification.

Answer Guided Questions

Describe the home, occupancy, comfort concerns, operating conditions, upgrades, and known problems.

Upload Utility Bills

Provide electric, gas, propane, or other energy information so patterns, seasonal loads, and unusual changes can be reviewed.

Take Photos

Photograph HVAC equipment, water heaters, insulation, ducts, windows, electrical panels, appliances, and visible conditions.

Receive Prioritized Actions

EcoPlatform™ organizes the information and identifies the home improvements most likely to reduce waste, improve comfort, and support better long-term decisions.

Contract-First Residential Analysis

Start With What Is Already Known About the Home

A home's age, location, construction type, foundation, climate, equipment, and documented improvements establish an informed engineering baseline. EcoAudit® then collects the information needed to verify what is original, what has changed, and what deserves closer review.

This approach does not replace professional judgment or required testing. It focuses that expertise where onsite confirmation, measurement, diagnosis, and technical review provide the greatest value.

Residential Energy-Audit Outcomes

A residential energy audit should help the homeowner understand what is driving utility costs, comfort complaints, moisture concerns, equipment performance, and future replacement needs. The result is a practical roadmap—not an unranked list of products.

Incentives and Tax-Credit Planning

EcoAudit® can organize information relevant to residential efficiency rebates and federal tax credits, including potential Section 25C opportunities. Eligibility depends on the home, equipment, project, location, installation date, and current program requirements.

Beyond the Audit Report

A Living Energy Record for Your Home

Unlike a traditional home energy audit that ends with a report, EcoPlatform™ keeps the home's assessments, utility history, recommendations, equipment, inspections, and completed improvements connected to one evolving property record.

Completed Work Becomes New Home Data

  • Equipment installed and efficiency ratings
  • Insulation and air-sealing work completed
  • Installation dates, costs, photos, and warranties
  • Tax credits, rebates, and supporting documentation
  • Inspection results and measured performance
  • Deferred recommendations that remain future opportunities

The Next Assessment Starts Smarter

Future analysis begins with what is already known about the home. The platform does not need to rediscover the HVAC system, insulation, windows, solar equipment, air-sealing work, or other improvements that have already been documented.

Every completed improvement makes the next home energy assessment smarter.

Frequently Asked Questions ```

Residential Energy Audit Questions

Learn how EcoAudit® RES replaces the traditional technician-led information-gathering visit, how EcoPlatform™ analyzes the home, and how completed improvements become part of a permanent Living Building Record.

What is a residential energy audit?

A residential energy audit is a systematic evaluation of how a home uses and loses energy and where improvements can reduce utility costs, improve comfort, strengthen indoor conditions, and increase building performance.

The assessment may include utility history, attic and wall insulation, air leakage, heating and cooling equipment, duct systems, water heating, windows and doors, lighting, appliances, ventilation, moisture, comfort concerns, operating conditions, and completed improvements. Rather than evaluating each component in isolation, EcoAudit® considers how the home operates as a complete building system.

How does EcoAudit® RES work?

Traditional home energy audits usually begin with a technician visiting the property to collect information the homeowner may already know. EcoAudit® RES reverses that process.

Using a smartphone, tablet, laptop, or desktop computer, the homeowner answers guided questions, uploads utility bills, photographs equipment and building conditions, documents completed improvements, and identifies comfort, moisture, or operating concerns.

EcoPlatform™ then applies Contract-First Architecture, building science, engineering expertise, and deterministic analysis to compare the documented home against its engineering baseline, identify where energy is being wasted, and prioritize the improvements that will produce the greatest benefit.

Can I complete the home energy audit from my phone?

Yes. EcoAudit® RES is web based and can be completed from a smartphone, tablet, laptop, or desktop computer. A phone is especially useful because homeowners can answer questions and take photographs while moving through the home.

What does the residential energy audit evaluate?

EcoAudit® RES can evaluate utility use, comfort concerns, attic and wall insulation, air sealing, HVAC equipment, duct systems, water heating, windows and doors, lighting, appliances, ventilation, moisture, resilience, solar, electrification, and completed improvements.

The purpose is not simply to create a list of possible upgrades. The protocol connects the home's systems, operating conditions, utility history, and documented improvements so EcoPlatform™ can establish what is driving energy waste and which actions should be completed first.

Does EcoAudit® replace the traditional technician visit?

Yes. EcoAudit® RES was specifically designed to eliminate the traditional technician visit used primarily to collect basic information about the home.

Instead of paying a technician to record equipment, photograph building components, gather utility bills, identify completed improvements, and ask the homeowner questions, EcoAudit® guides the homeowner through that same information-gathering process directly. The people who know the home best provide the information through a structured web-based assessment.

EcoPlatform™ then analyzes the submitted information using Contract-First Architecture, building science, engineering expertise, and deterministic analysis. The platform compares the home's documented characteristics against its engineering baseline, determines where performance has been compromised, and prioritizes the improvements that will have the greatest impact.

Specialized testing or additional technical analysis may still be used when a specific condition must be measured or verified. Those services are targeted to answer a defined technical question rather than being used as a general information-gathering visit.

What happens after the residential energy audit?

Completing EcoAudit® is the beginning of the building-performance process, not the end.

The submitted information becomes part of EcoPlatform™, where the home's utility use, equipment, envelope, operating conditions, comfort concerns, and completed improvements are analyzed together. EcoPlatform™ then prioritizes actions according to energy impact, cost, comfort, practicality, available incentives, project dependencies, and implementation readiness.

Approved improvements can move into RetroCore™, where the work can be scoped, coordinated, implemented, inspected, documented, and added to the home's Living Building Record.

Can the audit identify tax-credit or rebate opportunities?

EcoAudit® can organize information relevant to federal residential energy tax credits, utility rebates, state programs, local incentives, and other energy-efficiency opportunities. Actual eligibility depends on the home, equipment, project, location, installation date, contractor, certification requirements, and current program rules.

How are completed home improvements used later?

Unlike a traditional home energy audit that ends with a report, EcoPlatform™ continuously builds upon what is learned about the home.

HVAC replacements, insulation, air sealing, windows, water-heating upgrades, lighting, solar, battery storage, utility history, inspections, warranties, photographs, project costs, incentive records, and other completed improvements become part of the home's permanent Living Building Record.

Future assessments do not begin with a blank slate. They begin with an accurate history of what is installed, what has already been improved, what remains unresolved, and how the home has changed over time. That makes future recommendations, budgeting, maintenance, and retrofit decisions more accurate with every completed improvement.
