Building Envelope Air Tightness

COURSE NO: M02-005
Building Envelope Air Tightness
Course Highlights

This online engineering PDH course describes the importance of improving the building envelope construction to provide better air tightness.  In addition, the course discusses the theory and practical applications regarding building envelope construction.


Infiltration in commercial buildings can have many negative consequences, including reduced thermal comfort, interference with the proper operation of mechanical ventilation systems, degraded indoor air quality, moisture damage of building envelope components, and increased energy consumption.  The objective of the study used in this exam was to investigate the impact of envelope air tightness on the energy consumption of typical commercial buildings in the U.S. Despite common assumptions that envelope air leakage is not significant in office and other commercial buildings, measurements have shown that these buildings are subject to larger infiltration rates than commonly believed (Persily 1998, Proskiw and Phillips 2001).


This 2 PDH online course is intended for engineers in the building industry who are interested in total integrated building design and operation in order to minimize energy use in the building and provide more comfortable conditions for the occupants of the building.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Building descriptions: retail, offices, apartments
  • Airflow models
  • Thermal properties, setpoints and schedules
  • Energy uses and scalar rations
  • Targeted air leakage rates
