Maggiano’s Restaurant at Friendship Heights
5333 Wisconsin Avenue, NW
Washington, DC 20015

A lot of the “building science” information we get was developed from cold-climate research, and the rules that work in Wisconsin or in Waterloo, Ontario are not always appropriate for the Washington, DC region’s climate, particularly in our warmer, more humid summers. What are the most common summertime moisture issues? What tools are used to evaluate them? And what are the cures—whether the simple fix for the number one most common complaint, or seven figure repairs for complex ones? 

In this presentation, an experienced hand at troubleshooting, Doug Horgan, Vice President for Best Practices at BOWA, shares lessons learned over decades of evaluating, repairing, and most importantly, preventing summer-time moisture issues. Profusely illustrated with over 100 photos, and presented in an open discussion style so everyone can contribute.

Networking reception: 6:30 – 7:00pm
Program: 7:00 – 8:30pm (“Medici Room,” 2nd floor)

Additional info
Parking available in Chevy Chase Pavilion for $4, with validation from Maggiano’s. F.H. metro is one block away; there is direct underground access into Chevy Chase Pavilion from Metro. Exit CC Pavilion at ground level and go left (south) to Maggiano’s, a few doors away. 

Learning objectives:

  1. Examine common moisture problems experienced in buildings in humid summer climates.
  2. Understand the main principles of warm weather moisture, where it comes from, the forces that move it, and how to keep it where it causes no harm.
  3. Discuss methods and benefits of humidity control HVAC equipment.
  4. Review wall, roof, and foundation construction materials and methods which are appropriate for our mixed-humid climate
