Dear Readers,
Welcome to our fifth Home Building Curiosity….Go Home! A division of Go Logic, Go Home is a design/build prefab Passive House enthusiast leading the way in energy efficient design and the continuation of learning.
Maine based, Go Homes are inspired by their local region’s natural landscape, as well as by its history, people, and culture.
All of their Go Homes meet Passive House (PHIUS) standards, and are prefabricated through a honed panelization process.
Passive House
An advocate for building homes that have the earth and future generations in mind, Go Home makes all their homes go passive. Achieving Passive House certification means that homes will use less energy, thereby paving the road to being net zero, or even net positive. A house requiring less energy to function, means less energy is needed in the first place.
Their homes’ air-tightness “meets or exceeds” Passive House (PHIUS) standards at .6 air changes per hour at 50 pascals (.6 ACH @ 50 Pa). And their homes are all crazy well insulated, as you shall read in the ‘prefabricated’ section.
They offer heat-recovery and energy-recovery ventilation systems with all of their homes. Three pane, high quality, windows are also utilized and placed accordingly to maximize heat gains from solar energy.
Go Home’s commitment to making not only their homes, but the world, Passive, can be admirably summed up in their last paragraph on their “Passive House” page:

Dear Readers,
Welcome to our third Home Building Curiosity, Ecocor! As with the first two Home Building Curiosities, Ecocor is not only a curiosity, but an inspiration in the field of sustainable building. Ecocor is exceptional in how it actually meets all five of William and I’s foundational principles in our mission. Based in Searsmont, Maine, Ecocor designs and manufactures prefabricated, Passive House (PHI) certified, net zero ready, small footprint, healthy living building components and homes.
Prefabricated
Ecocor is very proud of their wall panels, and they rightly should be! Their walls are prefabricated at their Searsmont location, allowing for a climate-controlled build of each panel. Every wall panel meets Passive House standards, and has a specific assembly structure that is even being patented.
The manufacturing of individual wall panels allows Ecocor, the architect, and the buyer to get creative, while still achieving a quickly and quality built home. They promote the motto of “If it can be drawn, we can build it.” Think of their walls as super insulated, airtight, lego blocks, that allow you to build your own unique passive home.
While their wall panels are prefabricated and allow custom builds, Ecocor does have a sector devoted to prefabricated, Passive House certified, modular homes. This branch is called Solsken, which means “sunshine” in Swedish. All of the homes in their Solsken Ecocor collection are named after flowers, which William and I love (because we were actually thinking of naming our potential pipe-dream homes after trees)!

Dear Readers,
William and I had the opportunity to listen in on a webinar provided by the Passive House Institute of the United States (PHIUS) on limiting embodied carbon in buildings: “Spaghetti Carbon-Era: Disentangling Operational and Embodied Carbon.” Admittedly, I just got the pun of the title…which is all the more humorous if you were to have seen their intro presenting page being that of pasta in a white sauce with bacon.
This seminar was very helpful in reiterating the importance of taking a holistically sustainable approach in home building and living. Not only should the home be environmentally friendly and energy efficient during its usage, but also in its construction and sourcing of materials. The ‘environmentally friendliness’ here is measured by the amount of carbon a home is responsible for emitting. PHIUS standards make a home accountable for its carbon footprint in its operation alone: as in, how much energy the home needs to function once it is already built. This they call “operational carbon” or, “OCO2e.” In the webinar, they expressed that the home has an even larger carbon footprint when its “embodied carbon” or, “ECO2e” is taken into account. Embodied carbon is the amount of carbon that is emitted in the overall construction of the home: from the harvesting, manufacturing, and transportation processes of all of the home’s required building materials. That pink fluffy fiberglass insulation and wooden studs and concrete foundation and drywall has to be made out of something and transported from somewhere…all of the materials have their own carbon footprints which then contribute to the home’s overall embodied carbon.
Two of the presenters, Ilka Cassidy and Steve Hessler, founded a business called “Holzraum System, LLC.” Within their business, they did their own study of how much of a home’s carbon footprint is operational and how much of it is embodied. They used five different homes as case studies.
Home One: built to meet 2009 building code
Home Two: built to meet 2009 building code with high performance systems
Home Three: built to meet Passive House standards, but with a high usage of foam
Home Four: built to meet Passive House standards, but with a low usage of foam
Home Five: built to meet Passive House standards, but with no foam.

Dear Readers,
I would like to introduce you to our next Home Building Curiosity, Dvele. Founded by two brothers, Kurt and Kris Goodjohn, Dvele creates prefabricated, net-zero ready, Passive House certified, homes! They are based in California, and maintain their mission to “…offer a wide-array of customizable, modern pre-fab homes that verifiably exceed all standards of quality and efficiency.” William and I are admittedly a little jealous that such young people are already achieving modular sustainable homes, but we are also incredibly excited that there are like-minded individuals that feel so compelled to change traditional home building into a holistically healthy endeavor- for the planet, and its people.
As we delve into Dvele, I shall be going through our curiosities according to my and William’s five main principles: Passive House, Net Zero, Prefabrication, Small Footprint, and Healthy Living.
Passive House
Dvele adheres to the Passive House Institute of the United States (PHIUS) standards in the design and construction of all of their homes. This allows their Dvele homes to use “65%-75% less energy than a standard home,” as well as preempt their homes to be net-zero ready.
Net Zero
Every Dvele home comes wired for solar panels not just because they are based out of California (where solar panels are now a requirement within state building code), but because it makes sense for the homes they build. Their homes all meet Passive House standards, which means that they require little energy to function in the first place. Combine an already highly efficient house with a sunny patch of land and a few solar panels…and BAM! Not only ‘net zero,’ but ‘net positive.’
While every home comes wired for solar panels to eventually be installed, their ‘upgraded’ Dvele homes can include installed solar panels and a battery backup…

What are the criteria set by PHIUS to be considered a Passive House? Dear Readers, As expressed in Blog Nine, “The Concept of a Passive House Exemplified through a PHIUS Certified Home,” PHIUS sets Passive House criteria according to the climate of the intended home...
