The MinnePHit House is inching closer to completion as the year draws to a close. We are very excited to be part of the project and wish the owners well on their journey toward move-in day.
Tim Delhey Eian, principal and owner of TE Studio was recently certified by the Passiv Haus Institut in Darmstadt as Certified Passive House Designer PHI.
TE Studio offers project certification through the Passive House Institute U.S. (PHIUS), the Passiv Haus Institut in Germany (PHI), or any other available authorized certifiers world-wide.
Thanks for those of you who came out yesterday to see the MinnePHit House in South Minneapolis. We literally had a full house and shared many great conversations after the initial presentation. Thanks for your interest. I suppose it did help that the StarTribune published an article about the project the same morning.
We thank those who came out to the Passive House in the Woods last night for the annual Passive House Days. It was a full house and we managed to raise the temperature inside by at least 5 degrees ;). Thanks for celebrating this first year of occupancy with us, the owner, Christine Frisk of InUnison Interior Design, and Josh Crenshaw of Morr Construction. We greatly enjoyed having you and look forward to Sunday’s public tour at 10.45 AM. There are still a few free tickets available. You can find them here: http://phitw8phdsun.eventbrite.com/
Today, we ran the first blower door test at the MinnePHit House in Minneapolis. The EnerPHit building standard prescribes maximum air-leakage for a retrofit Passive House of 1,0 ACH50 (air changes per hour at 50 Pascal pressure). Converted to CFM50 (cubic feet per minute at 50 Pascals), we were shooting for a magic number of 300 or less. Immediately, the house outperformed this with a reading of 285 CFM. We spent the rest of the morning with help from the Energy Conservatory, Ryan Stegora (builder) and Paul Brazelton (owner) identifying leaks. Some were patched right away—others marked for later improvements. At the end, we measured a steady 267 CFM50, which corresponds to 0.88 ACH50.
We are excited to see that even a 76 year old home can be made virtually airtight, and we are confident that the builder can improve on the performance of this rough-in result for the final test. The Passive House recommendation for retrofits is at 0.6 ACH50 (about 183 CFM50). This means that the home is currently one “Passive House in the Woods total air leakage” from achieving this reach goal.
To put things into perspective, this home started with a blower door result of 8.5 ACH50 and a corresponding 2,100 CFM50 of air leakage. Since then, it grew by almost 40%. Many existing homes we tested over the years in the TwinCities range from 7 to 15 ACH50. According to the Energy Conservatory, average new construction is in the range of 3 – 7 ACH50, with exceptional builders getting down to 1.5 ACH50 on occasion.
We are very pleased with the performance, which also reflects positively on our detailing and specifications.
Minneapolis – The free, self-guided 16th Annual MRES Solar Tour Saturday, October 1, includes open houses at about 50 Minnesota homes, businesses and organizations that have solar and other renewable energy installations. Organized by the Minnesota Renewable Energy Society (MRES), the tour includes open houses in the Twin Cities and several other Minnesota communities from 10 a.m. to 5 p.m.
For the first time, this year the online guide to sites at www.MNSolarTour.org will list each site’s additional eco-friendly features. Besides the usual pictures, maps and details about alternative energy technologies for each site, the guide will list eco-friendly features such as urban chickens, electric cars, rainwater storage systems and the like. Tour guests must register at www.MNSolarTour.org to obtain addresses of the tour sites.
“The solar tour is popular with people who are thinking about purchasing some kind of renewable energy technology because it gives them a chance to see lots of systems and talk to lots of owners,” said Laura Cina, managing director of MRES. “The lists of other eco-friendly site features this year should draw even more people to the event.”
The owner, representatives from TE Studio, as well as representatives from Energy Concepts will be on site during the day to answer your questions.
