This slideshow was given by Tim Delhey Eian at the 2012 Passive House Conference in Denver, CO. The topic is 2-years of active monitoring of the Passive House in the Woods in Hudson, WI, designed by TE Studio. The slideshow contains a lot of full-screen images but no subtitles, therefore omitting some of the information which would have been given verbally during the presentation.

  43. 43. “Hey Tim, This is funny.  I had a problem with a frozen Humus package falling behind the lower freezer door preventing me from closing the door.  I wasnt able to retrieve it nor determine how to remove the freezer door to retrieve the obstructing food item.  I called the Liebherr customer service center and they provided me with guidance to remove the upper freezer door to reach the Humus and thus I was able to restore the doors to their closed position.   Meanwhile, I was baking a pizza.   I had a feeling that I was going to mess up my houses energy usage for today.  Its nice to know that I have friends watching out for me.”© TE Studio, Ltd.
