For the past 17 years, Joe Lstiburek and Betsy Pettit have hosted an annual conference, the Westford Symposium on Building Science, near their home in Massachusetts. Informally known as “summer camp,” the invitation-only gathering attracts hundreds of builders, engineers, architects, professors, and building science researchers.
The attendees listen to presentations at a conference center during the day and relax in Joe and Betsy’s backyard during the evening.
This year’s conference was held on August 5-7. Speakers included Michael Blasnik, Mike Steffan, Gary Klein, Kent Browning, Achilles Karagiozis, Chris Schumacher, Dave Ober, Joerg Birkelback, Marcy Tyler, Ed Retzbach, Andreas Holm, and Joe Lstiburek.
Covering familiar territory
If there were any devoted readers of GBA at the conference, they probably recognized the information provided at several of the summer camp presentations this year. At the Westford conference, Blasnik discussed the limitations of energy modeling software, a topic covered in a GBA blog published in March 2012. Blasnik also discussed bad energy retrofit advice, a topic which GBA has covered in at least three articles: A Plague of Bad Energy-Saving Tips, More Energy Myths, and How Not to Save Energy.
(The PowerPoint slides that Blasnik used in his presentation can be viewed by clicking one of the links at this Web page. The page also includes links to some of the other presentations from this year’s Symposium.)
Gary Klein, a renowned expert on domestic hot water systems, discussed several ways to reduce the time required for hot water to travel from a water heater to a faucet. GBA has reported on Klein’s calculations and advice in several articles, including Inefficient Hot Water Piping Layouts Waste Hot Water and All About Water Heaters.
Joe Lstiburek’s presentation focused on his proposal that ASHRAE 62.2 be replaced with a new residential ventilation standard. His…
