Southface experts present basic principles of building science, with emphasis on heat transfer (the conversion and exchange of thermal energy between objects, materials, or systems). An understanding of heat transfer can guide informed investments and best practices for improving home energy efficiency. Specific topics covered include the three types of heat transfer (radiation, conduction, convection), a basic overview of heat flow calculations, and recommended practices for retrofits and other efficiency improvements in the attic.

This course consists of a video training, slide deck, and exam.


After successful completion of this training and exam, participants will be able to:

  • Define types of heat transfer (radiation, conduction, convection)
  • Define and demonstrate an understanding of a convective loop
  • Identify the thermal envelope of a house
  • Demonstrate an understanding of best practices for insulation coverage
  • Identify recommended best practices for insulating key points in an attic and attic access


Upon successful completion of this course, participants will receive a certificate of completion for CEUs from ICC, AIA, and BPI and will attain the certificate Southface Certificate of Completion C.


Mike Barcik | Technical Principal

Mike Barcik is a Technical Principal at Southface and has been with the organization since 1995. With B.S and M.S. degrees in mechanical engineering from Georgia Tech, Mike is the author of numerous technical resources and has developed and led thousands of trainings for RESNET, BPI, LEED, DOE, EPA and other programs. He’s active in energy code development and often leads workshops on the latest code changes. Since 1999, Mike has trained over 1,500 individuals in RESNET’s Home Energy Rating System (HERS) program, and in 2010 he helped create the Duct and Envelope Tightness (DET) Verifier program to certify over a thousand individuals for blower door and duct leakage testing, as required by the 2009 and later energy codes. Mike served as LEED Faculty for BD+C, EB O&M and Homes, as well as helped develop and teach the EarthCraft family of sustainable programs. Mike co-authored Decatur Georgia’s High Performance Building Ordinance which requires third-party certification for new and substantially renovated single-family, multi-family and commercial projects.
