President’s Message
2020 has arrived and looks to be a great year for MIAQC and its members. We’ve already have started planning for our 2020 IAQ & Energy Conference being held in October in Portland. Our board held a strategic planning session in November to set our workplan and project goals for the next 3-5 years. We are excited about this process. Some of our goals include: 
Updating our public policy policy position statements on matters that are critical in improving and maintaining the indoor air quality in our homes, offices and public environments. We will be reviewing, updating these policy papers and sharing these with our members.
Improving our public communications and increasing our social media presence. This includes more engagement and messaging to the public about strategies to improve IAQ, and creation of a MIAQC YouTube channel to showcase some of the great information we have available.Want to help? If you are interested in assisting our organization, please reach out and let us know your thoughts. Contact christy@maineindoorair.org or 207-626-8115.

Feature Article:
A Practical, Easily-Built Wall System: R-30 and Beyond
 Contributed by MIAQC Members David Johnston of David Johnston & Co. and William Turner, of Turner Building Science and Design.
The adoption of the 2015 International Energy Conservation Code has special ramifications for Climate Zones 6, 7, and 8. As shown in Table R402.1.2, IECC 2015, Zones 6,7, and 8 are effectively precluded from using “Cavity only insulation”. The minimum requirements of code compliance are written as “20+5” or “13+10” in the Wood Frame Wall R-Value column. The first number refers to cavity R value, and the second number refers to a continuous layer of insulation. Non-insulation elements of the wall system, such as gypsum wallboard, plywood sheathing, or air films are not useable in the insulation calculations. The 2009 IECC did allow an option for “cavity only insulation”, written as “20” or “13+5”.The obvious intent of the 2015 IECC is to manage conductive heat loss by minimizing thermal bypasses in the wall systems, thereby improving overall system performance. Continuous insulation methods that comply with the Code include standard stud construction with insulated exterior sheathing, standard stud construction with insulated interior sheathing, Zero Stud Construction such as Structural Insulated Panels or Insulated Concrete Forms, and finally Double Stud Construction. This paper will explore one such Double Stud Construction method, which the authors refer to as “Wrap and Strap” Construction.Read more…
