“Passive House: The Building” Ralph Wafer and Anthony Garavaglia on Green Time TV

Architect and planner Ralph Wafer and Anthony Garavaglia, of Trumpet Constructors, LLC, discuss details of constructing the first Passive House in St. Louis.  Attention to detail was critical for achieving Passive Building Standards for minimizing heat gain in summer, minimizing heat loss in winter and holding air infiltration to near zero.  Exterior walls of the entire first floor are 14” thick insulated concrete forms.  Walls of the second floor are 12” thick structural insulated panels.  The roof uses 15” thick panels.  Sun shades over south-facing windows reduce solar heat gain during the summer.  This Green Time (No. 440) features “Passive House Revolution.”  It is produced by the Gateway Greens in conjunction with KNLC Channel 24.  Call 314-727-8554 or contact [email protected] for info.  [Find out about the movie at http://passivehouserevolution.org/]
