Step by Step Home Audit Inspection 

1. Pre-Inspection

The Pre-inspection primarily involves getting your feedback on past utility bills, current comfort issues, and future objectives.

2. Exterior Inspection / Walk-around

This inspection includes visually examining factors such as your home foundation/structure, safety, and energy system points of interest.

3. Interior Inspection / Walk-around 

The extremely important step includes the same type of visual inspection inside your home. Both obvious and not so obvious energy variables will be reviewed.

The square footage of your home and each individual room will be measured. This will be very important in understanding the right amount of energy usage for you.

4. Calculate Home Square Footage 

It is normal for a home not to be equipped for the proper airflow needs which impacts your comfort level and energy usage. 

5. Calculate Building Airflow Standard (BAS)

A blower door is a machine used to measure the airtightness of buildings which helps physically locate air leakage sites in the building envelope.

6. Perform Blower Door Test 

7. Combustion Appliance Zone Inspection & Preparation

Each household appliance is closely checked for connection condition, general safety observations, and BTU output 

The objective of CAZ testing is to determine if combustion appliances will vent under worst case conditions and protect the occupant from the hazards of draft reversal.  

8. Combustion Appliance Zone WCD Test 

9. Oven & Cooktop Testing

This test ensures your oven and cooktop is not generating unsafe levels of carbon monoxide within your kitchen area.

This step uses pressure gauges to better understand pressure differentials and leaks within your home ductwork/ventilation system.

10. Assess & Prioritize Air Leakage

BAS ventilation needs, air sealing, and mechanical ventilations levels will be calculated towards the overall work scope.

11. Calculate Air Sealing 

12. Insulation Analysis 

The best possible opportunities for improved insulation will be identified including specific type and amounts.

13. Test Out 

Various modifications will be made based upon what was found in previous steps to get a true measurement of necessary improvements.

A report will be created to outline the findings for the home energy audit as well as a prioritized breakdown of recommendations. 

14. Report & Recommendations
