Silicon Valley From Space

Silicon Valley From Space

Over the weekend I put up what I hope will be an important resource in the goal of achieving 100% zero-net energy homes in California by 2018 - a new website for the Silicon Valley Passive House Coalition.

From the site:

SVPH is helping local municipalities to set challenging but practical goals for maximizing energy efficiency and carbon emission reduction in the local communities of the San Francisco Bay Area and Northern California.

Nabih Tahan, who spoke two weeks ago at a BuildItGreen event on the passive house concept, just told me about Passive House California. They are "a group of building professionals from the San Francisco Bay Area working together to increase public and media awareness of Passive House."

You can check their website for more information, including their meeting this coming Sunday in Berkeley:

Date: Sunday, February 22
Time: 3:00PM (new participants) | 3:30PM (returning members)

About Me

My name is Nils Davis. In my day job, I'm a product manager at a software company - my product is for other product managers, so my job is very "meta." I have a technical and marketing background and love the world of technology.

But I'm also a budding green building maven. My particular focus is zero-net energy homes and the associated technologies, practices, policies, and legislation. My BHA goal is to that by 2018, 100% of California's new homes will be zero net energy. This will require big changes in building practices to make homes much more energy efficient (such as using the passive house approach), significant reduction in the cost of energy generation capabilities like solar photovoltaics, and market-readiness for electricity storage capabilities like home-scale hydrogen fuel cells.

Nabih Tahan's passive house remodel in Berkeley

Last night BuildItGreen's South Bay Professional Guild hosted Nabih Tahan, a Berkeley-based architect who was recently featured in a New York Times article on passive houses. Nabih discussed the passive house concept and how it is being applied in Germany and the rest of Europe, as well as his experience building Low Energy Houses (Niedrigenergiehaus - the generation of homes before the passive houses) in Austria and remodeling his conventional house in the Berkeley flatlands into a passive house.

The Smith House - A passive house in Urbana, IL

What if you didn't have to heat your house at all, no matter the climate? Or at least, never turn on the furnace? Well, that's practically what life is like in one of the "passive houses" designed with the principles of the PassivHaus Institut in Darmstadt, Germany. Recently featured in an article in The New York Times, No Furnaces but Heat Aplenty in ‘Passive Houses’
