On Thursday 23 April (tomorrow as I write this) I will be giving a brief talk about passive houses and my recent visit to the 13th International Passive House Conference in Frankfurt last week. The talk will be in San Francisco at the Prana Restaurant on Howard St., starting at 7pm.

[I] will provide a report on the 13th International Passive House Conference… This is the premier conference on passive homes, homes so energy-efficient that they don’t require a furnace or air conditioner to keep their occupants comfortable.

I went to the Menlo Park City Council meeting last night to provide an in-person comment on their Climate Action Plan (CAP) draft. The draft has been circulating for comments for a few months and last night was the presentation of the comments from council staff to the council. As you may recall, my friend architect Matt Harris and I provided a comment on the CAP.

Report and Insights From The Passive House Conference – Part 1

This entry is part 1 of 1 in the series Passive House Conference 2009

I got back yesterday from the 13th Annual Passive House Conference in Frankfurt, Germany. My biggest takeaways from the conference are:

  • While the growth of passive houses in Europe is impressive, even in Europe there are still marketing challenges
  • The opportunity to use energy efficient buildings as a hedge against climate change is immense
  • We are way behind on energy efficient building here in the U.S. – in fact, essentially no one in the U.S. is doing this kind of building.

A Passive House White House

What if the White House were a Passive House?

What if the White House were a Passive House?

David White, an architectural energy technical consultant at Transsolar, sent a letter to President Obama recommending the Passive House as a new energy efficiency standard:

I’d like to draw your attention to one approach to energy efficient building, which is called Passive House … the most stringent residential energy efficiency standard in the world.

White goes on to describe the Passive House approach in more detail, and ends with this call for a subsidy and/or mandate.

Individual Action Is Not Enough

March 26, 2009 in agriculture, analysis, energy efficiency, green building, opinion, policy by nils | Add your comment

Someone entered this topic in an online forum to which I subscribe:

The main problem with lowering the carbon level is down to individuals, to behaviour, to good citizenship and that is the biggest challenge of all… how many times to you see careless behaviours? how do you change that?

I just had to respond. I think this attitude is the best way to make sure that end in the end, nothing good happens. I’m reprinting my comment on the topic below, unedited (even though you all know about passive houses already).

How Should Local Planning Commissions Reward Energy Efficiency?

As I discussed in my earlier post, Code changes and incentives are critical for energy independence, it’s going to be tough to change the energy efficiency of our building stock until building and planning commissions provide incentives to owners and builders to take those extra steps, and spend that extra money.

Code Changes And Incentives Are Critical For Energy Independence

Patricia hit the nail on the head in her last post, No Blarney here! – Turning up the Heat:

Where are the codes and incentives?

Or rather, how do we get people to build and renovate houses to energy efficiency levels that are significantly above code?

The Architecture 2030 website has a great reference on how much beyond code you must build to achieve their interim and final energy efficiency goals. For example, in California’s we have a new 2008 version of the energy efficiency code, usually called “Title 24.” To meet the Architecture 2030 interim goal of buildings that use half as much energy as their conventional peers (the “initial 50% reduction target”), buildings in California need to be 10% more efficient than required by this new building code.

Slideshows About The Passive House Concept

Bronwyn Barry's Passive House Conference Report

Bronwyn Barry's Passive House Conference Report

I was contacted the other day by Bronwyn Barry, a designer and rater at Quantum Builders, and a member of the Passive House California organization up in Berkeley, so I did what any normal internet user would do – I Googled her. And I was excited to find, as one of the first results, a slideshow she’d made and put up on Slideshare. It’s a trip report from her visit to the 3rd Annual North American Passive House Conference held in Duluth last November. And, not only is Bronwyn’s presentation there, but there are several others, including one from Tim Eian, a German-born architect now working in Minnesota, and several others:

Biohaus: First Certified PassivHaus in the U.S.

The other day I posted about one of the first passive houses built in the U.S. I just ran across another passive house example – this one is the first U.S.-built home to be certified to the German Passivhaus standard. The house was built at the Concordia  Language Villages in Minnesota in 2006, partially funded by the first-ever grant to a U.S. recipient by the German environmental foundation Deutsche Bundesstiftung Umwelt (DBU).

The First U.S. Passive House – Super-Efficient, Affordable

The Big Wall of Windows

While the passive house concept is taking off in Europe, where over 10,000 passive houses have been built, there are still very few in the States. I have posted before about Nabih Taleb’s passive house remodel in Berkeley, and I’ve heard about a few more which I’ll be posting soon. But this month the Taunton Press’s Green Building Advisor website is featuring an article on America’s first “passive house.”
