Last week, we enjoyed a visit by Oliver Klein, CPHC, LEED AP, who presented some of 475’s efficient materials and explained how passive house construction can be attained in a New England climate.

Synopsis

The name “475” is a reference to the heat demand requirement of the Passive House Standard, 4.75 kBtu/sf./yr. Passive House is the gold standard for high performance envelope construction today. Learn about the strategies and materials used to achieve this extraordinary level of performance in today’s best performing buildings.
