passive design

Note: The detailed breakdown of each section and subsection can include explanations of the concepts, case studies, real-world examples, and specific passive design techniques.

heat exchange

MVHR heat exchange

takes bad air from wet rooms and put it outside to prevent mold and odors through heat exchange

takes fresh air from outside through heat exchanger and puts in inside

U-value rating

how much heat can get through

lower number the better
