Residential Energy Audits

Building Performance Evaluations

Increasing your home’s efficiency isn’t just switching out light bulbs or buying new appliances. It’s approaching your home as a complete system. Heating, air-conditioning, insulation, water and other systems can all work together to effectively reduce energy consumption and potentially help lower your utility bills.  When considering installing renewable energy sources such as solar, evaluating your energy efficiency and making upgrades may lessen the cost of your system.  Reduce before you produce!

Water conservation and energy surveys are highly recommended but not required. By participating in SCEIP, you are making a financial investment; this decision should be made based on both the efficiency and the cost effectiveness of the improvements. Conducting a water and energy audit will help you assess water conservation, energy efficiency, and renewable energy opportunities for your property.

Energy: Online surveys can be conducted through the PG&E website. Residential property owners can obtain an onsite survey by hiring a Home Energy Rating System (“HERS”) rater, or equivalent. Visit the California Energy Commission for more information about the benefits of energy evaluations.

Water: Property owners should also check with your local water provider to see if free water conservation surveys are available. Costs incurred to conduct onsite audits or surveys may be included in your application for SCEIP financing.
