The Green Roof Has Arrived

Passive House in the Woods Green Roof

The green roof on top of the garage has just been installed. I captured this image in the afternoon hours so it is a bit hard to make out the little plants with the shadows of the trees to the West obscuring the view. The early spring, warm temperatures and frequent rains should help it fill in quickly. This vegetated roof will be very pleasant to view during the ascent to the rooftop terrace, which was also partially planted.

On an unrelated note, I captured the image below of the shadows of the trees on the stucco of the West facade. I always liked how shadows animate the stucco facades and create an interesting visual interaction between the house and its natural surroundings.

This Wisconsin Home is Minnesota GreenStar® Gold

May 3rd, 2012 by Tim Delhey Eian

The Passive House in the Woods received the highest Minnesota GreenStar® certification (Gold) today. We are very excited to see the certification come through and congratulate the owner and all the team members involved in the design and construction on this achievement!

We used the Minnesota GreenStar® program to compliment the Passive House certification. It’s green markers helped track resource efficiency, indoor environmental quality, water conservation, and reduced site and community impact, with the energy efficiency requirement being met and exceeded by the achievement of the Passive House certification.

It’s a Net-Energy Positive Home

January 3rd, 2012 by Tim Delhey Eian

This just in: The Passive House in the Woods in Hudson Wisconsin officially clocked a net-energy positive meter reading in 2011.

What does that mean?

In short, it made more energy than it consumed. While we predicted this with our energy models, we found and learned through monitoring that some equipment and appliances use more energy than assumed. On the flip side, user behavior plays a major role as well and can effectively lower energy consumption over the predicted model.

Starting the journey towards energy neutrality and beyond with a Passive House works really well, as the building is designed to provide a comfortable environment with very little energy input. The addition of carefully sized renewable sources, such as photovoltaic and solar thermal can then balance the remaining energy flow, or reverse it.
