Allison Bailes to Teach an Interactive Online Class

This October, Allison Bailes will begin teaching a ten-week online course called ‘Mastering Building Science’

Posted on Jun 6 2014 by Martin Holladay, GBA Advisor

Dr. Allison Bailes is a rarity: a physicist with a sense of humor. He's also a regular blogger on GBAGreenBuildingAdvisor.com.

If you've enjoyed Allison's blogs over the years, and aren't intimidated by the prospect of homework and studying, you may be ready to take an online course from Dr. Bailes.

The upcoming ten-week course is titled "Mastering Building Science." Marketing materials note that the course is not intended for novices: "Maybe you’ve taken a HERSIndex or scoring system for energy efficiency established by the Residential Energy Services Network (RESNET) that compares a given home to a Home Energy Rating System (HERS) Reference Home based on the 2006 International Energy Conservation Code. A home matching the reference home has a HERS Index of 100. The lower a home’s HERS Index, the more energy efficient it is. A typical existing home has a HERS Index of 130; a net zero energy home has a HERS Index of 0. Older versions of the HERS index were based on a scale that was largely just the opposite in structure--a HERS rating of 100 represented a net zero energy home, while the reference home had a score of 80. There are issues that complicate converting old to new or new to old scores, but the basic formula is: New HERS index = (100 - Old HERS score) * 5. rater or BPI class. Perhaps you’re an HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. designer or installer, architect, or engineer who sees a benefit in becoming a master in building science. ... This class is for the person who has a handle on the fundamental principles of building science already. You know, for example, how heat flows, the meaning of ACH50, and how much mechanical ventilation air is required by ASHRAE 62.2A standard for residential mechanical ventilation systems established by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. Among other requirements, the standard requires a home to have a mechanical ventilation system capable of ventilating at a rate of 1 cfm for every 100 square feet of occupiable space plus 7.5 cfm per occupant.. What you want now are more specifics, more details, and more depth."

Students who sign up for the course are promised "lots of personal interaction with Dr. Bailes and your classmates."

Presented in collaboration with Heatspring, an online education portal, the course is scheduled for October 6 to December 12, 2014. The cost is $1,295. Early-bird discounts reduce the tuition to $995 for those who enroll before August 31.

More information is available on the Heatspring website: Mastering Building Science.
