Building Science Fundamentals

Denver, CO

Building Science Corporation has rescheduled all the two-day Fundamentals Classes to November and December of this year. The new dates are posted on the website.
The two one-day Renovation Classes will take place on the dates scheduled but they will be web-based only. Note that the registration fee for the two web-based events has been adjusted downward.

It is with great regret that we have to cancel the 24th Annual Westford Symposium on Building Science…aka “Summer Camp” that was scheduled for August 3, 4 and 5 of this year.  Summer Camp will be held next year on August 2, 3 and 4, 2021.


Building Science Fundamentals is a two-day, $895.00 seminar that teaches the basic knowledge needed to design and build durable, energy efficient, affordable and healthy buildings.

Dr. Joseph Lstiburek will discuss building science principles (such as the control of heat, air and moisture and IAQ) and show you how to apply them to low-energy enclosure design, advanced HVAC systems, forensic investigations, and the repair and retrofit of existing buildings.

The Fundamentals class has been attended by thousands of builders, architects, engineers, building science consultants, building code officials, facility managers, building product manufacturers and government officials.

The fee includes breakfast and lunch but does not include travel or accommodations.
