We’ve been comfortably situated in our home for three seasons, from the vernal equinox to almost the winter solstice.The house has performed admirably, meeting our expectations for energy consumption and comfort through hot spells in summer and some recent cold snaps. We were snug as bugs during a particularly violent storm in June. The architectural layout has been a joy — all main rooms have nice views and lots of light. The twelve inch exterior insulation wall provides a deep overhang that in summer keeps direct midday sunlight from entering the south facing windows, while in winter the low light bathes the rooms.

The house has the distinction of being Michigan’s first Passive House by virtue of its certification by the Passive House Academy.

As expected, the two minisplits that provide cooling and heating are seldom used at the same time. In summer, we ran the upstairs unit in dehumidification mode and only a couple times ran the lower unit in the same mode. So far this heating season, we have only used the downstairs unit. In spring and autumn they are simply not used.

The energy recovery ventilator runs day and night, quietly refreshing the air at the rate of one house change every three hours. This system uses a cross-current heat exchanger and moisture element to maintain the interior temperature and humidity. Having an appropriate humidity level in wintertime is a real pleasure — no shivering when stepping out of the shower in winter!

We’ve had the pleasure of making new friends who have an interest in this kind of home and we look forward to following their progress with similar projects. Several weeks ago we enjoyed hosting an energy auditing class from the University of Michigan-Flint that came armed with a blower door apparatus and thermographic camera to study the house.

The combined kitchen and parlor space has proven to be a great place for gatherings. During the warmer months we use the wraparound porch for reading, meals and hanging up clothes to dry. In the colder months, we dry our clothes with a condensing dryer; a key benefit with an unvented system like this is that all of the energy used goes toward heating the house.
