It’s been almost a year since we started work on the Passive House in the Woods. It’s about time that it makes an appearance on the blog. So without further ado, here is an image and a description.
The Passive House in the Woods is a 1,900 square foot two-story single family home with walk-out basement level, and a rooftop terrace. It sits on just over one acre in the Town of Hudson, WI—minutes from interstate 94. Located on the outer edge of a residential development, the home overlooks the St. Croix river valley. The building lot provides stunning views Read more →
I recently edited this article and thought it’d be a good idea to put it back on the blog as an entry. This entry is permanently linked on the right hand side under pages.
Passive House is a rigorous, voluntary building energy standard focusing on superior energy efficiency and quality of life at low operating cost.
Passive House is the highest certified building energy standard in the world, with the promise of reducing the total energy consumption of buildings by up to 90%, while providing superior comfort and indoor environmental quality. When Read more →
You are cordially invited to the first Passive House Minnesota meeting.
We are looking to found a local organization to support and promote the Passive House building energy standard. We are looking for planners, designers, engineers, builders, vendors, suppliers, educators, lobbyists, building geeks, and energy conservationists—basically professionals who would like to support and promote the Passive House building energy standard. Join us at the meeting and become a member of a strong lobby for a strong concept.
We’ll be meeting in suite 512 (AIA conference suite) at International Market Square in Minneapolis. (NOT in the AIA office)

I just finished reading “The Green Tragedy” by Pat Murphy. I’ve had the pleasure of meeting Pat at the 2008 and 2009 Passive House conferences. I admire his sensibility for the dilemma we currently face in respect to energy and buildings. IMHO, this book is a great summary of what’s going on in the building industry right now. It’s not all bad, as Pat points out a number of opportunities to make things right. Thumbs up and thanks for your work, Pat!

Here is the link to the Merriam-Webster website entry.
Carbon footprint (1999): the negative impact that something (as a person or business) has on the environment; specifically: the amount of carbon emitted by something during a given period.
On that note, remember that Passive House building energy standard creates buildings with the lowest certified carbon footprint (for operation) in the world.
I just watched “The End of Suburbia“. This movie is already 5 years old. However, it may actually be more fun to watch it now than it was in 2004. Many of the predictions made in the movie can be matched to today’s realites—especially the economic situation. I think it’s good food for thought. I am not trying to jump on a suburbia-is-bad band wagon here, but frankly, neither is the movie. It’s trying to put it into the context of 21st century challenges like energy, economy, social fabric, and aesthetics.
Here is a summary from netflix’s page:
This provocative documentary, a regular on the film-festival circuit, examines the history of suburban life and the wisdom of this distinctly American way of life. A post-World War II concept, suburbia attracted droves of people, giving rise to sprawl and all that comes with it — good and bad. How has the environment been affected by this lifestyle, and is it sustainable? Canadian director Gregory Greene dares to ask all the tough questions.
Share in the comments section how you feel about this movie.
This Independence Day marks the first anniversary of TE Studio!
We would like to use the opportunity to thank our current clients and potential clients for their business and support during this first year. Without them there would not be a TE Studio! Thanks also to the many supporters that believe in us, Passive House, and Deep Energy Reduction Retrofit. We feel that these are the most sustainable options to preserve the planet for our children, and create real value for our clients that insulates them from an uncertain energy future.
We look forward to the construction of our first Passive House project, as well as Deep Energy Retrofit projects that target a 70%+ cut in energy use for existing homes.
Here is to building a sustainable future.
Linden Hills Power & Light was kind enough to invite me to lecture on Passive House and Deep Energy Reduction Retrofit in August. Here is an excerpt from their program:
Aug 25 –We Love Retro
Join our architect specialist to learn the ins and outs of deeply retrofitting old homes. A Deep Energy Reduction Retrofit (DERR) project will cut 70% or more of the energy use of buildings. You’ll also learn about the Passive House building energy standard. Passive House represents today’s highest certified building energy standard, with the promise of reducing the total energy consumption of buildings by up to 90% while providing superior comfort and indoor environmental quality – all at little or no additional up front cost. When combined with renewable energy systems such as solar photovoltaic or solar thermal, Passive House puts true zero energy buildings and carbon neutrality within reach.

Thanks for attending my lecture at the Green by Design conference. It was a fabulous event and many great ideas were shared. In the spirit of the conference I am offering my slideshow for review at slideshare: http://www.slideshare.net/timeian
Since most of my slideshows don’t have a lot of text or bullet points, you may want to look at the Living Green Expo slideshow, which was designed to run without my presentation and offers lots of frequently asked questions and answers.
In my spare time 😉 I’ve been working on a design for an urban Passive House. The design is meant to fit a standard size east-west facing lot. The floorplan offers a first-floor bedroom and bath, as well as an open kitchen, living, and dining area. The second floor offers a flexible layout that can be configured to hold up to 3 bed rooms, 1 bath, and a common room. This urban Passive House works either with or without a basement. Depending on the configuration, it offers between 1,675 and 2,475 usable square feet.
The roof is designed to hold solar-thermal panels that face due south at a 55 degree angle. It also offers plenty of south-facing real estate for PV panels. Ultimately, this Passive House is designed to become a net-energy positive building, e.g. it makes more energy than it consumes and pays its inhabitants by selling excess energy to the grid.
The garage building mimics the main building’s roofline. The main body of the house would be stucco, the gable-ends lap-siding. The roofing is standing-seam metal. The trellis on the south-facade shades the windows below in the summer months. It offers the potential to grow vines on it. Additional solar panels could be located on top of the trellis if so desired.
This is what a blower-door looks like. It is being used as part of an energy-audit to determine the performance of a building. The blower-door itself is placed inside an exterior door frame. It pressurizes or depressurizes a building at 50 Pascals pressure, based on the testing method. A meter provides a read-out of the air-leakage of the building. This tells us how “leaky” the building envelope is. We can also search for these leaks while the blower is running. Tracer gas can be used, but a simple lighter will often do the trick as well, as its flame will start to move or even get blown out once near an air-leak. More obvious leaks can usually be felt, as they create significant drafts.
Knowledge is everything. It is the foundation of a good building performance upgrade.
Once problem spots are identified with the help of a blower-door test for example, the actual problem can be addressed properly. Follow-up testing can show the success of any improvement measure at the end of a project. Consider it a quality-control measure.
While the blower-door is running, a thermal imaging camera can be used to identify thermal properties and imperfections of the building envelope. In this picture a cold spot along the edge of a wall-to-roof connection can be seen. The pressure difference that a blower-door creates will emphasize these issues in areas where air-leakage is a contributor to the temperature difference.
Energy Audits can be compared to a visit to the doctor. You know something is not quite right and you are looking for clarification and answers. The doctor’s visit is your first step to getting answers and coming up with a strategy for healing. With buildings, energy audits are the equivalent to a doctor’s visit. They tell architects and contractors what’s not quite right and where areas of improvement are. Knowledge is key to success. Once the issues are identified, they can be dealt with and solved most efficiently and effectively.
Energy Audits can typically be ordered from your utility company. They are heavily subsidized, so you on make a small copay. If you are considering working with an architect or contract, please invite her/him to the audit—there is nothing quite as powerful as first-hand knowledge transfer. At the very least, ask your auditor for a written report and photos of any problem spots she/he identifies.
Kare11 did a feature on energy audits. Make sure to order the extended audit. This one includes thermography.
I think this has been up for a while as it was recorded almost a year ago. I was just alerted to it by a potential client.
Thanks to Bill Karges for inviting me into his house and to talk about Passive House building energy standard.
Thanks to all that visited the TE Studio booth at the Living Green Expo! We had a great time and enjoyed talking with all of you about Passive House and Deep Energy Reduction Retrofit.

I just read a passage in ACI‘s “Moving Homes Toward Carbon Neutrality” whitepaper that I find to be a wonderful summary of the paradigm shift the building industry needs to accomplish. In my opinion designers, contractors and homeowners alike need to consider the building as a system in order to understand how to make significant and truly valuable improvements—not just in regards to energy.
In housing we have discovered that moisture and mold problems, combustion spillage, and indoor air pollution can only be addressed by the systems approach, whereas the component by component approach of old did not work. With all of these problems, the interactions between components of the house were very important, but were not always obvious when we looked at one component or area at a time. For example, while the moisture problem may have seemed worse in the bedroom of a sick child, it often started either outside or in the basement/crawl space. Combustion spillage problems in the utility room were sometimes caused by the powerful new kitchen range hood. Changing a natural draft furnace to a high-efficiency one, without introducing controlled, low-rate ventilation, often resulted in the build-up of pollution indoors that was worse than the occasional spillage problem from that furnace. All these were system problems and they were much more easily identified when the systems approach was used.
I encourage anybody who is thinking about remodeling to look at ACI’s whitepaper and consider the opportunities it highlights. A building is like a set of dominoes: tip the first one over and a whole bunch of others will start to fall also. Each component has an impact on other components. Together, they work in concert—creating a wonderful symphony, or a ghastly amount of noise. It is therefore of utmost importance to carefully and decisively create a retrofit composition that enhances the features as well as the performance of a building, and returns the favor with a Whole that is greater than the sum of its parts (okay, I borrowed that one from the last Passive House conference).
Beauty, delight, performance, efficiency: those are some of the things that fascinate me with buildings. Hence the company slogan: beautiful, resource-efficient buildings. The systems approach is key to success on these fronts.
Last Saturday, a group of people who are interested in Passive House gathered at the Red Stag Supperclub in Minneapolis to exchange thoughts, ask questions, and share visions. Fourteen guests joined host Tim Eian and special guest Stephan Tanner for a 2+ hour long event. The group was comprised of people who are interested in building a Passive House, educators, students and professionals.
Stephan and Tim shared the basics of Passive House design in a cold-climate. Stephan offered insight in some of the specific challenges of building the Biohaus in Bemidji, MN. He also covered many building design-related questions and talked about materials available in the U.S., while Tim answered questions about Passive House education through PHIUS (Passive House Institute U.S.) and ongoing work in his practice.
A great part of the discussion focused on similarities and differences between “standard” construction and Passive House design. Stephan offered the comparison of the 150 mpg car. He pointed out that while standard design and construction practices can yield incrementally higher performance utilizing existing paradigms, Passive House in a cold climate offers a leapfrog approach with extreme performance. At the same time, Stephan cautioned of a much smaller margin of error as well as the requirement for great attention to detail in both planning and execution.
As a group, we decided to collect thoughts and ideas following this first meeting to develop a schedule and agenda for future events.
I invite you to send your comments and thoughts to help with this process.
