We have had a very enjoyable and busy summer taking some time off from updating the blog, but it is back on! There have been a few house tours we hosted early and mid summer for a group of people from Fresh Energy, the City of Minneapolis and a few others. It is always fun to share with the groups and educate on Passive house design. It turns out our oldest son enjoys giving tours as well and he impressed a group of people when he explained what blower door testing is, how it is performed and why it is important (see old post for more information on how it went).
