The Taylor Home Energy Audit...What is it?
The Comprehensive Home Assessment has two phases. The first phase consists of the contractor taking inventory of, and reporting on, the current conditions in your home, including the following:

Health and safety (Carbon Monoxide levels/ Moisture problems)
Air infiltration rates
Insulation levels
Domestic hot water system
Heating system efficiency
Cooling system/central air conditioning efficiency - if applicable
Distribution system (ductwork) - if applicable
Lighting
Major appliances

The second phase consists of the participating BPI-certified contractor developing a workscope for proposed improvements, including a cost and energy savings estimate.

How is it done?
Participating contractors use a number of diagnostic tools during the first phase of your Comprehensive Home Assessment. Some of the tools the contractor will use are:

Carbon Monoxide (CO) Analyzer: Important Health and Safety tool
Blower Door: Measures the air tightness of a home and identifies areas where air leakage is occurring
Duct Blaster: Measures how ‘leaky’ the ductwork is in a home (This tool would only be used in a home
that has a forced air heating system and/or central air conditioning)
