    New Mexican Adobe, German Efficiency Style

    I’ve seen several projects pursue both LEED Platinum and Passive House certification, but I can’t think of any that actually went through with the aim other than this Passive House, Platinum-certified home in Taos, New Mexico. The 2,400 square-foot home has three bedrooms, two bathrooms, a garage, and 1.1 acres of land with a serene, scenic view of Taos Mountain to the east, Truchas Peaks to the South, and pasture land to the west.

    Zero Net-Energy Ready Homes to be Certified by Energy Department Partnership

    For people who think Passive House is a Fad.

    On Monday, August 20, the U.S. Department of Energy (DOE) announced a newpartnership between the DOE Challenge Homeprogram and the Passive House Institute US to cooperate on the promotion of various levels of high-performance buildings on the path to zero net-energy.

    This news is a huge development for the passive house community and for PHIUS. The endorsement of PHIUS+ passive house certification through the DOE instantly makes passive house the most energy efficient option for builders, designers and developers who want to achieve a zero energy building. This recognition will go a long way toward making passive house mainstream.

    This took a lot of time and effort, and we owe thanks to Sam Rashkin, Chief Architect at the DOE, whose knowledge, vision and determination were critical to the effort. (Sam was the keynote at last year’s North American Passive House Conference.)

    So, how does this partnership change current PHIUS+ passive house certification and what do consultants need to know?

    In a nutshell: not much. A passive house already fulfills most of the Challenge Home requirements – certification essentially remains the same process with a few minor additions! Those additions are very good improvements, making the home even better. Indoor air quality requirements ask for low VOC materials and the water efficiency requirements establish a reasonable savings baseline, all good things.

    The Challenge Home requires rigorous third-party, on-site verification, which already is part of PHIUS+. PHIUS+ certified RESNET Raters already use an advanced passive house checklist created specifically for passive houses. (This testing protocol is actually more rigorous than the one the Challenge Home is using.)

    What Challenge Home brings to the table that PHIUS+ did not before is a more formalized exterior water management and flashing checklist. Having seen quite a few bad water management details during certification so far, we are happy to add a more formalized process to assure the long term durability of the house. QAQC is crucial to assure quality in execution, actual performance and peace of mind for the client we found.

    Zehnder America, Inc. is Recognized for its Cutting-edge Residential Heat

    Zehnder America announces that it has completed the 3rd party testing of the Zehnder ComfoAir 350 HRV and has joined the Home Ventilating Institute (http://www.hvi.org) who is making these test results public. This breakthrough is the confirmation that Zehnder America is leading the way of the next generation of Heat and Energy Recovery Ventilation Systems in North America. Zehnder’s ComfoAir 350HRV with its counter flow heat-exchanger recovers over 90% of the room temperature. As a result, during a cold winter day, the incoming fresh air into the ho

    Light 12-Glazed Window on the Horizon, at R-38

    In the USA, most windows are probably single- or double-glazed and some builders will use triple-glazed windows for Passive House and other high-performance homes. But in Hanover, Germany, a 12-glazed window prototype by Mariusz Paszkowski and Antoni Kostka was the star of the recent International Passive House Conference, according toDer Standard. Check out these windows with aerogel!

    The two scientists, in conjunction with SUPERWINDOWS, showcased INVIS160stack and INVIS160tweed, and both of the prototypes are about 160 mm thick, though they weigh no more than a double- or triple-glazed window unit.

    Energy Efficient Buildings in Demand Worldwide

    We cannot sustainably keep pace with the world’s continuously growing hunger for energy if we continue along our current path. Especially in the building sector, however, there exists an enormous potential for energy savings where we can reduce energy use by 80 to 90% without any reduction in comfort.

    Countries around the world are realizing this. Only “Net zero energy buildings” will be built inSouth Korea and California as of 2020 and throughout Europe, all new builds will have to be constructed as “nearly zero energy buildings” by 2020. Europe’s future energy efficiency directive also calls for high annual retrofit rates of public building stock

    Video: The Passive House Revolution By Charles Hoxie

    Video: The Passive House Revolution By Charles Hoxie.Twenty years ago, German physicists erected a home that demonstrated how little energy a building would need if built with, among other things, thick insulation and airtight walls. The so-called “ Passive House ” (or “Passivhaus” in German) was soon …
