We were started in 1972 when, after graduating from Sacramento State University, John Sutter, joined the Petaluma Carpenters Union.  In 1979 he started his own remodeling company. 


In 2007 Applied Building Science moved into its new 3000 square foot shop and office in central Santa Rosa.  During this time the company began expanding its knowledge base and scope of work into energy efficiency retrofits and solar photo voltaic generation.


ABS’s retrofit work typically begins with an audit by one of our Building Performance Institute trained and certified Building Energy Analysts. Based on the audit findings, we meet with clients to evaluate and agree upon a retrofit program. Usually ABS is retained to turn the agreed upon  corrective measures into reality.  Such retrofit measures typically include work on the building’s insulation, air barriers, water heating, space heating and cooling systems, windows, moisture issues, ventilation, electrical loads, and lighting. 


After reducing energy waste and improving indoor air quality, we then sometimes take the final step of providing a solar generating system, thus moving the building towards supplying as much energy as it uses (a so called “net zero energy” home) .


ABS’s mission is to utilize the latest in building science and technology to reduce energy waste, utility bills, and greenhouse gas emissions in buildings while increasing their healthfulness, comfort, and durability. We bring a heritage of over 60 years of renovating and remodeling to this task.  From building energy audits, to simple weatherization measures, to deep energy retrofits, to full blown Zero Net Energy retrofits, our company is the North Bay leader in building performance assessment and upgrades.
