"We partner with other like-minded organizations to deliver quality sustainable education. We hope to influence building professionals in the most positive way, so they may contribute to a healthier, vibrant, sustainable local community."


The seminar will present the attendee with detailed information on indoor air quality as it applies to existing and new buildings.  The subject will be presented by practitioners that test IAQ in existing buildings,  see patients that suffer from the effects of poor IAQ,  and design and construct new buildings.  LEED Indoor Environmental Quality credits will be discussed in reference to LEED 2009 and LEED v4. 

Registration fee: *$65 General Admission
Lunch will be provided. 
*AIARE and USGBC-REC Members will receive a one-time $10 discount code. This code will be sent in a separate email.
Continuing Education Credits:

Healthy Building Science

Alex Stadtner

Alex started on the path of environmental work in college, where he attained a degree in Environmental Science & Environmental Policy. After college he worked for two years as a Sustainability Manager at Antioch College, before moving to New Hampshire to earn an MS in Resource Management & Administration at Antioch New England.


After graduate school, he worked with green building consulting pioneers at the Center for Maximum Potential Building Systems in Austin, and then a Portland-based company specializing in third-party building rating systems, especially LEED. Since then Alex has completed numerous environmental testing inspection courses to broaden his knowledge of the industry and bridge the gap between environmental science and building science.



Dr. Eric Gordon


Dr. Eric Gordon

What Dr. Eric Gordon emphasizes is listening to his patients. "I believe my patients. Their description of what is going on in their body is the most accurate way we have to assess what is going on with them. 

I interpret the information they present, and blend it with laboratory results and imaging and other tests to determine a protocol that is customized to their condition."


Patients with poorly defined chronic illnesses react differently to all types of environmental stressors and medical interventions. While one patient may respond well to a particular protocol, other patients may not respond at all, or even have a negative reaction.


Dr. Gordon knows there is an interwoven complexity to these illnesses. There is a layering of the body's adaptations to environmental toxins and infections from pathogens that is unique to every person, depending on their genetic susceptibility, organ vulnerability, toxic exposures, medical history and life circumstances. The body's various biological systems - immune, endocrine, neurological, gastrointestinal and so on - influence each other and are influenced by each other, both in the development and progression of illness, and also its resolution. Read more.

Environmentalist (CIE) Board-awarded by the American Council for Accredited Certification.

David comes to Healthy Building Science with a background in all phases of property development and management. 


 His knowledge of building construction and environmental science makes for a unique blend, and enables David to identify problems in buildings sometimes before they are even visible!


David holds two degrees from the University of CA at San Diego, one BS in General Biology/Biochemistry, and a BA Major in Music Performance with a minor in Economics. When he's not inspecting or collecting samples you might find David managing his properties, playing volleyball, acting on stage, sailing the San Francisco Bay, or even flying solo overhead in his plane!

Larry Strain
Larry Strain been involved with sustainable design for over 35 years. He studied ecological systems at the Evergreen State College, and was a student instructor at the Farallones Institute in Occidental, California. Larry received a Masters in Architecture from UC Berkeley in 1983, and became a partner at Siegel & Strain Architects in 1990.
In the early 1990's Larry began to systematically research sustainable materials and construction methods and in 1996 he wrote Resourceful Specifications - guideline specifications for environmentally considered building materials and construction methods - awarded the 1998 Practice & Technology Award from the AIA, East Bay Chapter.  Resourceful Specifications was later published by as part of the GreenSpec Directory.
Mr. Strain was project principal for the Portola Valley Town Center, a LEED Platinum Project and AIA COTE Top Ten winner in 2009. He served as project principal for the Camp Arroyo Environmental Education Center and the Emeryville Resourceful Building Project, a project that did ground breaking research on affordable green housing and Life Cycle Analysis. Both projects were Top Ten Green Projects by the AIA COTE in 2002 and 2000.
Larry has spoken widely on green materials, sustainable design, construction efficiency and green specifications, at local regional and national conferences. He has taught sustainable design courses at U.C. Berkeley, and in 2001 taught at the International Laboratory for Architecture and Urban Design in Venice, Italy. Larry is a LEED AP and Fellow in the American Institute of Architects.
