My partner and I would arrive at a house, set up
our blower door, peek through our infrared scanner,

But more important than these gadgets was
the knowledge, gained from ten years of research
at Princeton University, of where and how most
buildings lose energy. Studying hundreds of
buildings under real-life conditions, the
researchers found many ways that heat escapes
by bypassing the usual weatherization measures of
weatherstripping and caulking. These thermal
bypasses can greatly compromise a home's comfort,
contribute to moisture problems, and add
significantly to energy bills (see
