Building a Passive House



no solar no Jew thermal and no windmill apparatus incite so how can this house being built in the suburb of Washington be green because the passive house focuses on reducing your energy demand to the absolute minimum David Peabody and his team at Peabody architects designed the first passive house in the Washington area passive houses he says are virtually airtight cutting the cost of heating and cooling by about 90% but what really sets this home apart from other so-called green homes is the fact that it's so unremarkable that is the beauty of the passive house approach is that you don't have to build in a particular way with any particular materials or to any particular style that's why in our case we decided to try to do something that was to prove that point to make something that was very traditionally American Peabody architects may have been the first to build a passive home in the Washington area but they are certainly not the last in nearby Arlington Virginia Roger Lin and his brother Eric are in the midst of building a passive home we want to have a lot of insulation as you can see here this is uh this is a foam board there's a two inch foam board you can see it's basically a continuous insulated house all the way down to the foundation even the windows are airtight when closed surrounded by a special foam that prevents air from leaking past the seals and these are triple pane a nearby neighbor Kathleen Harrison says she is thrilled to see passive homes coming to her neighborhood I'm very excited that passive is coming here to the US and that they're integrating a lot of things from what I know in Germany because my family was in a construction business there the house is so airtight that on a crisp winter day with the temperature around 4 degrees Celsius the temperature inside the house even while still under construction is a comfortable 12 degrees in here it's above 50 right now architect David Peabody says you can find passive homes all over the world in North Africa for example has a passive house community designing for very hot dry climates and that's a whole nother area of exploration for passive house the first passive home was an apartment building in Darmstadt Germany built about 20 years ago with the help of two physicists one of whom went on to found the Passivhaus Institute in Darmstadt they developed a methodology and they developed a energy modeling software that people like me can use who don't we're not physicists despite some of the specialized materials used in construction like precast concrete panels the ventilation system or the prefabricated insulated board the total cost of building a passive home is only about five to eight percent higher than a traditionally built house but a passive house uses only 10% as much energy as a conventional home savings that can offset the initial investment relatively quickly Rebecca ward VOA news

    See how a passive house is build in the Heart of Vancouver Island CanadaPort Alberni's first Passive house in the Heart of Vancouver Island, to date we have 30 individual detailed videos from the foundations up, Search google for seumas2 in youtube once opened go to the top and click on videos, the videos will be in reverse order, more as the build progresses. We never used tyvek or OSB, used moisture and air barriers products from EU, double wall BC 2X4 DK studs, 20 ins thick, Rockwool insulation R 80 walls ceiling R80, pad R55, triple glazing R 7.5, large windows facing South, small facing North, 1/2in plywood sheating, no air leakage, all joints and air infiltration taped, widow wells splayed at 45 degrees on the outside (wide angle view) heat exchanger (EU) heat pump hot water heater, wiring placed in the double wall cavity ( no drill holes in the studs, dropped ceiling allows the same, moisture barrier placed 1/3 distance in from the interior wall, High heel trusses, Improved under felt on the roof shingles,for further details view the videos. Wheel chair accessible, electrical switches one foot lower and the power plugs placed 4ins higher for that reason, Stay tuned as the build progress to the finish stage producing other 12 plus videos. slainte mhath macduff
