Case Study 1: Roof Insulation & Attic Air Duct Sealing

For this home, we performed multiple energy audits and home performance assessments to ensure our efficiency solutions would best fit the unique needs for this space.

This client was a participant in the SMUD Home Performance Program.

And as a qualified member of the residential program, this homeowner was able to put down $8000 in rebates from SMUD to complete this project.

After Installation of Home Performance Split System

We removed the rooftop package unit and replaced it with a split system located in the attic near the center of the house.

This allowed us to reduce our duct surface area and more efficiently deliver air to all parts of the house. We also insulated and wrapped the skylight wells. In addition, insulation was added to both the attic and crawlspace.

Lastly, some air sealing was done to seal the house to 0.35 air changes per hour.

Case Study 2: Residential Home Solar Panel Installation

Homeowner, Lynda, from Petaluma, purchased a 6 kW system with Solar World Panels. This solar energy system included Enphase Micro-inverters that included internet monitoring.
