BioHealthy Homes’ building biologists Scot Appert and Dr. Caroline Bearss can help reduce utility bills and carbon emissions through an in-home energy audit. The BPI-certified residential auditors will perform blower-door testing and infrared thermography as they inspect homes to determine where energy is being lost. Technicians will also conduct a combustion safety test and evaluate which systems are working inefficiently and which appliances are indulging in late-night kilowatt snacks.

BioHealthy Homes can also drag domiciles through a more extensive analysis with a Healthy Home inspection. Energy excavators will use meters to measure the home's electro-magnetic radiation levels, including electric fields, magnetic fields, and high-frequency radio waves. BioHealthy's analytical inspectors will then use a compass to detect geopathic anomalies that can affect sleep areas. After test results come in, BioHealthy Homes will consult with customers about applicable mitigation suggestions, and then perform a visual mold inspection. Each home inspection can help detect domestic issues related to air quality and toxicity, and will also include a consultation on healthy lighting, building materials, air purifiers, and vacuum systems that can keep homes ship-shape without filling them with orange lifejackets and Jolly Rogers.
