A live presentation in Seattle as part of the NW Ecobuilding Guild's ongoing speakers series.
There are many paths, certifications and techniques to building Net-Zero buildings. The Passive House design helps achieve great efficiencies in buildings, reducing long-term costs and stacking functions in the living area, but is it the best? The Northwest is rich with styles, knowledge and experts, creating buildings that produce energy to power themselves and beyond. Join us as our presenters discuss their experiences developing Passive House and other Net-Zero designs, highlighting the ups and downs of each model in the Northwest environment, and what has helped their buildings achieve this sustainability goal.
OUR PANEL OF SPEAKERS:
Dan Whitmore, of Indicator. After wearing many different hats during a 30-year career in construction, Dan likes one particular style: the “thinking cap.” Building goals can and should be far reaching with respect for style, craft, place, and the world in which they are built.
Ted Clifton Jr., of TC Legend Homes. With a focus on building with Structurally Insulated Panels (SIPs), Ted builds Net-Positive energy homes, capable of powering themselves and an electric car, for about $200/sq. ft.
Joe Giampietro, Principal with Nicholson Kovalchick Architects, designs, builds and develops multi-family housing, bringing high-performance, low-energy building to the real estate industry for over 25 years. As an architect and landscape architect, Joe is committed to LEAN construction initiatives, improving the quality of our built environment.

One selling point of properly designed passive home / net zero home which I haven't heard mentioned too much, is that if/when the public utility systems go down, like power / water, etc, I would like to have a house which had ability to run on-grid or off-grid, meaning battery / solar, and local water storage cache, so when utility service goes dead, the house continues to function normally, and is not reliant on public services.

In Europe we have heavily taxed energy and fuels, so ROI on heat exchanger vs gas boiler is a no brainer in a multi unit building. The same goes for insolation, waste water heat recovery units in hotels. EVR or HRV is essential in a modern building for air quality. Computing waste heat can be used to heat water and/or space. I like Tiny house Studio apartment designs for it's efficiency use of conditioned space. As more and more appliances uses DC power there is a need for more efficient ways to deliver PV power to them. We should support Open source hardware and software that is designed to last, be upgraded, repaired, refurbished, lastly recycled

One word of advice. When a panel member is pointing to the projected screen to show a house or project, have the cameraman show it and not just stay on the panel members. Also the audio is very poor on every one of these videos that I have watched. Good info, but hard to hear or see it!!!

This is all so interesting! One question I have though, if a hairdryer is enough to heat a house in winter, how does one combat that in summer? If I use my hairdryer or cook or bake anything in summer, wouldn't that be like using both an air conditioner and a furnace at the same time? wouldn't they be running at cross-purpose?

A year late... These types of homes are built to be very airtight so they don't rely on poor construction for air exchange. They have powered ventilators that bring filtered fresh air in and out in a very controlled way. The incoming air is distributed into all the living areas and the outgoing air is taken from moist, smelly, or hot rooms like kitchens, bathrooms, and laundry rooms. You can temporarily set these ventilators to a boost mode to directly help mitigate a short-term heat or moisture increase. I should also mention that the incoming and outgoing airstreams travel through a heat exchanger. These ventilators usually run at a low speed 24/7. They can also have co2 sensor to increase ventilation if you have a lot of people over. In regards to additional cooling... If you are using multiple efficient mini-splits to cool your home you would only be cooling the zone that got warm and not the entire building. It's really not any different from what happens if you were to bake in the summer in a traditional building. The mini-splits and ventilators are all variable speed and you don't normally operate them at maximum. You can have a very targeted response to a heat spike without changing the climate in unaffected rooms.

Is there concern for using SIPS type wall construction? ... rumors of these type walls say there are problems getting termite inspection when house is sold. Rumor says because the nature of foam insulator, termite inspectors cannot see the trademark wood trails left behind when the insects burrow in wooden sill plates, and framing members. I don't know if all termite inspectors think this way, or if they all refuse to do an inspection because of the foam elements. It may be well and fine if one builds a SIPS type home for themself, and lives in it their whole life. Wondering if you've heard of inspection and home sale problems. On another note. What about using hempcrete instead of concrete for walls and foundation, etc ... would using such materials prevent getting the needed level of airtight-ness?

Dan says using code level of insulation in multi family development now and meeting PHIUS in Seattle. We are suppose to be reducing our fossil fuel and energy use not just meeting code. PHIUS+ is too relaxed a standard we should be meeting PHI international standards in Seattle especially

Joe said he is working on a passive house project that a code built wall meets PHIUS standards in Seattle. That is ridiculous. We are not reducing C02 or GHG by meeting code. PHIUS standards are too relaxed from the true Passivhaus purpose to save the environment

So, how many times are you going to repeat your comment? I read it once and that’s enough. By the way I still think you’re right with your comment

I hate to blow your excitement but, currently, I very much doubt that early Passive House projects will reach their goals for performance and payback, wood materials made from chips and sawdust are not ready for primetime. Tapes and Tarps will be the downfall of these projects.
