Hammer & Hand

Take some time to browse the website and Field Notes section of Portland/Seattle based builders Hammer & Hand.  Their site is a wealth of how-to information on high-performance building.  If you are considering building a Passive House, you might be interested to watch this video of the Pumpkin Ridge Passive House owners.

10 Predictions for High-Performance Building

This article is very inspiring.  Among the predictions I’d like to see come true are more high-performance windows manufactured in the US, as well as public education about the benefits  of designed/controlled ventilation.

Enjoy the article in Retrofit Magazine.

 

Proud Green Home

Who wouldn’t feel proud to call this home?   This is not a Passive House, but at Net Zero it’s achieving all the positive aspects of high performance building that I care most about.  It is healthy, responsible, creative, and efficient! The home builder has an excellent Proud Green Home Websiteso that you can learn all about the features of this design. Let’s congratulate the owner, builder and the architect, LG Squared, for their achievement.

Passive House – A Building Revolution – Documentary

Order your DVD today or stayed tuned as we try to organize a local screening here in Madison.

Passive House — a Building Revolution! describes the beginning of Passive House in America’s super-insulated houses of the 1970s. Although abandoned here, the movement was carried forward by building scientists in Germany. Today there are 25,000 such buildings in Europe. The film explains the environmental challenge and opportunity represented by buildings. Passive houses should cost less than conventional buildings based on a lifecycle cost analyses and can provide better comfort and air quality. The film also introduces the importance of deep-energy retrofits in reducing energy consumption and CO2 emission from our 113 million existing homes.

The film showcases Passive House innovators across the country – architects, builders and home owners, as they share their reasons for choosing to build a Passive House or do a deep-energy retrofit on their own home.

Here are a few of my favorite quotes from the trailer:

“It’s a development of a kind of liberation.  You do not depend on oil, you don’t depend on nuclear energy, you just depend on your own knowledge and your own work and you can do it with your own hands. and it will be a better comfort and a better quality of life with this technology.” – Dr. Wolfang Feist

“It’s a  beautiful profound thing to have a building that is really serving you with such a tiny amount of energy.”  – Chris Benedict

“I really belive that safe energy is the invisible oil that is in existence everywhere and everyone can access it.  Nobody has to buy it from anybody, just smart building techniques will access that wealth, the wealth of conserved energy, and anybody can get it.” –  Katrin Klingenberg

Passive House Video

This video features The Passive House Academy’s Tomas O’Leary explaining some features from his own house in Ireland.  I had the benefit of attending Tomas’ training course in the winter of 2013 and credit this course with my success in passing the Passive House Certification Exam.  The video provides a basic introduction to some key aspects of PH design.  I love that Tomas designed a floor-to-ceiling window wall that actually admits more energy than it looses over the course of a year.  He also does a quick job explaining the basics of a mechanically ventilated home.

No Furnace – “heat with a hairdryer”

Last night I attended the Wisconsin Women Entrepreneur’s networking dinner and found so many people interested to hear more about the Passive House Standard.  So I thought I would share a 2008 article from the New York Times that provides a basic discussion on  this German program.  Awareness of these high performance buildings is key.  I am working on community presentations to host around Madison. These seminars will help spread the work about how we can build and renovate smarter.  For a more in depth look at the details of construction this NYT blog post provides a great graphic.

Don’t Call it Passive House!

I think this blog post really sums up the nomenclature problem surrounding Passive House.  Passive House Certified or not, I want to endeavor to design a high performance house that suits your budget.  The article also touches briefly  on the economics of financing an energy efficient house. I’m going this this process right now trying to find land to build my own house so I’ll let you know how the discussion is framed at the bank.

A high performance home is a “highly optimized, thermal bridge free, energy sipping marvel of modern age architecture and engineering”.  The design and engineering for high performance homes is holistic act that starts from day 1 with proper siting and orientation to maximize solar gains with attention to view and privacy.

Stay tuned for a  post about the economics of Passive House – and how you can try to hit the sweet spot of minimal extra costs for countless benefits including abundant daylight, large windows, no drafts,  clean air, quiet interiors, and more!

New England Passive House Retreat

This compact house features high performance and efficient use of space in a small package.  The client sought a two bedroom, two bath home that was right sized for their family – nothing more, nothing less.  They also had a goal of minimizing the home’s energy use.

The iconic and compact form of the gabled roof lends itself perfectly to the Passive House standard.  This project is an example of  thoughtful high design that minimizes complex construction in order to shift budget into efficient mechanical systems.  At the end of the day the project is stunning and the cost to operate the building is incredibly low.

The design firm behind this project is named ZeroEnergy Design.  According to their website, “We believe that great design should enhance the value of each place, make optimal utility of space, elicit an emotional response, and use less energy.  Our designs are inspired by clients and the surrounding landscape, resulting in an architecture that is uniquely informed by both subject and place. We are also committed to designing homes and buildings that use 50% less energy than building code requires, in pursuit of energy independence.”

Wisconsin Passive House in the Woods

This is an older story, but one that I want to feature now that I am a Passive House Designer working in the cold climate of Wisconsin.   Please take some time to browse this website to learn about project which was built between 2009-2010 in the town of Hudson, WI.  I appreciate that this that house has no boiler and no furnace yet remains comfortable and net-energy positive during the winter.  (I can talk with you about Passive Houses can endeavor to achieve this level of comfort and energy savings)

According to the team, the house ” blends economy, ecology, health and durability in ways only Passive House can. The project sets out to demonstrate that this level of performance and quality can be achieved with today’s technology—even in an extremely cold climate.”  Congratulations to Tim Eian of TE Studio for being one of the first in Wisconsin to promote Passive House building technique.

I hope they host another house tour soon!

New York Times on Passive House

I was so excited to see the headline in today’s New York Times featuring Seattle’s first Passive House.  The article does a very good job reporting on the basics of the PH Standard as well as some of the controversial topics surrounding the debate on how to build high performance buildings that don’t cost that much more.  As a Certified Passive House Designer I am trained to integrate the complex construction details of the PH Standard in well considered architectural designs.  I can understand how the targets of PH are daunting to some, but for me this is just the new normal.

I find it unfortunate that the article reports an estimated 5-20%  additional cost associated with PH, without  mentioning the extra money put into the high performance building enclosure is nearly offset by smaller  mechanical systems and dramatically reduced monthly utility bills!  It’s true that extra insulation, triple pane windows, and air sealing tapes are extras costs not associated with typical houses. But what is also not expected in typical houses is chance to live in a  supremely healthy and comfortable indoor environment.  In the coldest northern winters the ventilation system provides a constant supply of fresh air (in contract to most buildings which tend to be stuffy in the winter).  In a PH all of the interior surface temperatures are much closer to body temperature so that means you don’t experience the same effect of cold drafts, even though there are no heating registers placed in front of windows!

While it’s great to see Passive House being featured in the NYT – I hope that this article furthers an in depth conversation about the benefits of what I recognize as the new normal in building design and construction.Park-Passive-Seattle-3 Park-Passive-Seattle-1
