Build the Address-Specific Energy File
Request any rating report, projected or confirmed rating certificate, blower-door documentation, duct-leakage test, insulation certificate, window and door product records, HVAC design or commissioning information, water-heating data, appliance specifications, solar documents, permits, and final inspections. Match the address, plan, orientation, equipment, test date, and version of the home.
Separate design-stage projections from field-verified results. Record the rater or contractor, method, software or standard named in the document, tested configuration, units, threshold or target shown, exceptions, and recommended corrections. Do not convert a number into a performance promise without the full report and qualified interpretation.

Check What Changed After Testing
Compare the dated file with current windows, doors, weather seals, attic access, recessed lights, exhaust fans, fireplace or combustion features, ducts, returns, filters, HVAC equipment, thermostats, additions, garage interfaces, solar equipment, and penetrations. Later work can change leakage, ventilation, loads, and modeled assumptions even when the original report was accurate.
Ask whether corrections noted during construction were retested and documented. A passed inspection, completed rating, and present condition answer different questions. Where records are missing or the buyer has a material comfort or efficiency concern, ask a qualified energy, HVAC, insulation, or building professional to define useful testing.
Use Utility History Carefully
Request available utility history through the proper transaction process, but do not treat another household’s bill as a forecast. Occupancy, thermostat settings, pool equipment, electric vehicles, solar production, appliance use, weather, billing periods, rates, vacant time, and maintenance can materially change consumption.
Use bills to identify questions and patterns, not to promise future costs. Reconcile unusual periods with equipment changes, vacancy, construction, leaks, pool operation, or solar interconnection records. Build the buyer’s budget from the exact home and intended use, with room for uncertainty.
Connect Results to Comfort and Repairs
A low leakage result does not by itself prove balanced airflow, moisture control, indoor air quality, duct condition, or occupant comfort. A higher result does not locate leakage or define the repair. Ask the professional to separate building-envelope, duct, ventilation, filtration, pressure, insulation, and equipment findings and to identify safe sequencing.
Price complete scopes: diagnosis, access, air sealing, duct sealing, insulation, ventilation, HVAC adjustments, electrical work, permits if applicable, ceiling or wall restoration, cleanup, and retesting. Confirm association approval where exterior equipment or openings are affected.
Compare Homes Without Overpromising
Use a common worksheet for rating date, verification status, tested features, later changes, HVAC and water-heating systems, pool or solar loads, utility-history limits, likely projects, and reserves. The best-supported file may be more decision-useful than a marketing label with no underlying documents.

Questions this page answers
Is an energy rating a utility-bill guarantee?
No. It depends on stated assumptions, verification, weather, rates, systems, maintenance, and occupant use.
Are projected and confirmed ratings the same?
No. Identify whether the document models plans or reflects completed-home verification and testing.
Does a blower-door result locate every leak?
No. It measures under a defined test; diagnosis and repair design require additional professional work.
Why review later alterations?
New openings, equipment, ducts, additions, exhaust, and penetrations can change the assumptions or tested condition.
Can one number prove comfort or indoor air quality?
No. Comfort and air quality involve airflow, moisture, ventilation, filtration, equipment, operation, and other factors.
How should buyers compare two homes?
Compare dated verified records, actual systems, later changes, utility-history limits, repair scope, and reserves.
