Net-Zero Energy Homes for the Masses

If you were to rank sustainable homes primarily based on their energy efficiency, Zero Net Energy homes would rank extremely high. They’re pretty cool — and complicated. Top U.S. home builder PulteGroup moves into the eco-friendly homes market by providing Zero Net Energy homes to the masses.

Practical Passive Solar Examples

Some examples of passive solar design applied to homes in the southeast, where cooling, as well as heating, is a concern.

Framing Double 2-by-4 Walls

I decided to build double 2-by-4 walls to achieve 14-inch thick super-insulated walls. This is just one way of achieving the high R-values for net zero energy homes.

Simple and Green Building

To me, the most important features of a sustainable building are not its technological wonders but its simple design features: common-sense strategies that should be incorporated whether the building becomes LEED certified, Energy Star certified, or is just trying to be environmentally friendly.

Changing the footprint for Passive Solar Gain

To build a net zero energy home, you'll need to design for passive gain. That requires a shallower footprint to ensure that the low-angled winter sun can enter and heat each room.

Building My Net Zero Energy Home: Design Priorities

This blog contains a detailed list of most of my initial design priorities for my net zero energy home so others may benefit from my thinking and experience on creating a passive solar, net zero energy, green home.

Building My Net Zero Energy Home: Key Early Decisions

In this blog, I highlight the earliest decisions I had to make to create a net zero energy home: how I was going to build the foundation and walls. Thermal bridging, air tightness, insulation, cost, and greeness are all key deciders.

Building My Net Zero Energy Home: The Back Story

In this blog, my architect James Plagmann and I begin to tell the story of the construction of Dan's new net zero energy homes. Dan begins by laying the ground, defining a few terms and describing his experience in this field.
