Energy Efficiency and Title 24 Experience

Tom's fundamental background in building science principles is augmented by successfully completing over 50 PG&E Pacific Energy Center, Building Science Institute, and Building Performance Institute classes that provide a broad building systems knowledge and approach to solving clients' building project issues. Tom has worked for recognized industry leaders such as Sustainable Spaces and Renu conducting home performance tests. He has prepared California building energy efficiency Title 24 compliance reports for his solar passive house and other projects.

Passive Solar Green Home Experience

In 1982, Tom planned, helped design, permitted, and managed the construction of a 3500 sq. ft. award winning solar passive house in Barron Park and reduced the construction costs by 25%, identifying the most cost-effective solar and energy efficiency features using the CALPAS building energy computer model. The house is designed so 70% of the winter heating load is provided by the sun while 100% of the summer cooling load is provided by a thermal chimney and thermal mass integrated into the house structural and building elements thus negating the need for an air conditioning system. His house won the City of Palo Alto 1983 Solar Passive Design Award and it has been on several solar home tours including the June 2008 Barron Park Green Home and Garden Tour which he helped to organize.


Tom has associations with several independent home performance testers, HERS raters, mold/lead/asbestos testers, building science trained HVAC contractors, Title 24 preparers, green architects, green builders, PV and solar thermal integrators. These associates assist in providing clients with a full range of experienced green building, energy efficiency and home performance testing services.
