Energy Performance Oversight and a Gas Guzzler Tax for Homes?

March 4, 2011

I know I owe everyone a redesign of our Performance Sticker and some talk of the various available home energy use metrics, but that is tall order, and I have been a bit short on time. So, instead I’m going to buy a little more time with a discussion of one of the lesser points that arose [...]

Two Point Five + 1two5 + .54

February 23, 2011

We just settled on the Two Point Five Beta yesterday marking the completion of Postgreen’s eighth house. We don’t have final photography or LEED results yet, so this is just a quick celebratory post with a more comprehensive one to follow.

Postgreen Homes Home Performance Sticker

February 15, 2011

We have talked about simple, mileage-style window stickers for homes before, but for some reason all that talk never led to action. We never actually created one for our own homes. Well, it’s time that oversight was addressed. I put together a draft version of a window sticker based loosely on the specs from the [...]

Permeable Pavement Options for LEED Projects

December 8, 2010

We have started to explore larger projects with our development company in Philadelphia that include shared off-street parking lots with a common driveway. This provides a new opportunity to explore more sustainable pavement options than the traditional blacktop used in most projects.

100k House Wins LEED for Homes Project of the Year

November 22, 2010

We just got back from Greenbuild in Chicago and are a little more tired than expected. That is probably because we had to lug this sweet piece of hardware back with us . . . That’s right, the 100k Project actually won the USGBC’s national award for LEED for Homes Project of the Year. We [...]

Energy Star Home – The Hybrid Construction Way

September 8, 2010

Over 1 million Energy Star Homes have been built to date in the US. Compare this to just over 6,500 LEED Certified homes and probably less than 20 Passive House Certified homes in the US. While Energy Star is much less stringent than the latter certifications, it is easy to see which standard the bigger [...]

100k Project is Officially LEED Platinum

April 21, 2010

The wait is finally over. The LEED for Homes Platinum Certification for both homes in the 100k project has been received. After a variety of delays including, most notoriously, the replacement of an incorrect bath exhaust fan, we have finally received official notice from the USGBC that both the 100k and (poorly named) 120k have [...]

Quick Air Sealing Strategy Notes

April 8, 2010

As we build the Skinny Project, we are taking care with all of our air sealing details and making notes on possible changes to reduce labor and complexity in all future homes. One of the key notes I picked up at last year’s Passive House Conference was that those who had been actually building these [...]

First we will briefly go over the LEED requirements and credits, and then we’ll take a look at the methods we used [...]

Passive House Ventilation Design

January 20, 2010

We thought it would be a good idea to review our new ventilation strategy and design implemented in the recent Passive Project. The ventilation strategy in the 100K House was different than most typical houses and the Passive Project took things a step further. We’ll start with the outline: Use a very efficient mechanical ventilation [...]
