Air Tightness Testing
as it relates to energy, comfort, and air quality in buildings

Retrotec offers three levels of Air Tightness training. If you do not currently have an account in Retrotec's Online Training, email us at training@retrotec.com. If you have an account, and are logged in, select the course(s) you'd like to enroll in from the list below. Please only enroll in one each of Level 1 and/or Level 2. Each course will end on the date specified. Enrollment will close on the 15th.

Level 1: The Science of Air Leakage in Buildings:

Acquire a solid understanding of the role that air leakage plays in buildings. The principles we will discuss apply to residential houses, the duct systems in those houses, apartment buildings, office buildings, commercial buildings, industrial buildings, and other large buildings and/or structures covering a multiplicity of uses.Since air leakage simultaneously affects energy conservation, air quality, building integrity and even safety, it is the goal of this Level 1 training to provide a basic understanding of the building science that affects that interplay, what measurements can be made, and how the results are of value.Level 2 goes on to teach how to make measurements on residential houses while Level 3 does the same for large buildings.


Level 2: Using Residential Air Leakage Measurement Equipment

Learn and completely understand the sensitive differential pressure gauges used in measuring and diagnosing air leakage in residential buildings. Learn how door fans (blower doors) work and how to use them effectively. Quantify duct leak and locate problems.


Level 3: Air Leakage Testing in Large Buildings

This unique course shares Colin Genge's 25 years of experience in testing large buildings. Learn all the specialized techniques he has developed to test buildings of almost any size. Learn the equipment set up for multi-fan and floor by floor testing, that allows testing on buildings of any size. Learn ASTM E-779, ATTMA and USACE Protocol from the person who wrote the standards, developed the equipment, and wrote the software.Learn how to handle the high bias pressures in large buildings and how to get accurate results under any and all weather conditions.
Level 3 will give you a good idea of the real problems that occur in high-rises, why they leak, and where they leak. You will gain a better understanding of the benefits of airtightness, the theory of air barriers and the importance of ventilation in well-designed high rise buildings. Questions that will be answered in the comprehensive Level 3 training include: What components of a building can be measured and what do existing standards require?What are acceptable air leakage levels and what kind of air leakage levels occur typically in high-rise buildings?How does measuring air leakage in a high-rise differ from residential testing? Different buildings require many different test setups which can in some cases become fairly complicated to meet the requirements of various testing standards.What kind of problems will you run into and how can they be solved?How do I determine how much equipment is needed for a particular test and what considerations must be made in quoting a test?
