A local reporter took a walk through the site late last week in an attempt to decipher how the big timbers are prepared by master timber framer Eric.

The cuts are all pretty painstaking and feature some pretty specific measurements. You will note that the angles and the notches are all scored first with a boxcutter and then the cutouts are made and shaved accordingly.

Thanks for putting up with the improvised narrative. Eric left before our crew could get over to him for some comments.

We will be talking to Eric in our next video.

Videos – Lou Fenninger’s Vision – Parts 1&2

Below you will find a two part video discussion courtesy of Lou Fenninger the founder of Net Zero

In the twin videos Lou talks about his vision and history with net zero building design.

Part 1 outlines his overall strategy and concepts. Part 2 delves into some design specifics and origins or his building design vision for the future.

Lou Fenninger is building a net zero energy home in Ontario’s cottage country north of Toronto. The winters are harsh. Thus the concept of Lou’s net zero design strategies must be coordinated to accept the demands of rigorous winters… and hot, sweltering and humid summers.

We’re always happy to hear from prospective home builders and designers.

The Moore House – A pueblo inspired themed house

The Moore House – A pueblo inspired themed house

Inspired by the architecture of the Pueblo Indians, the Moore house was designed by Doerr Architecture to create more energy than it uses, a net-zero energy home. Mike and Ann Moore had property at an elevation of almost 8000 feet in the Rocky Mountains of Colorado and wanted a 3500 square foot home with space to show their art collection. They wanted a home that captured the feel of adobe architecture as well as the views of the continental divide while treading lightly on the earth.

Architect Thomas Doerr alluded to Pueblo buildings with a composition of simple forms that have flat roofs, plaster walls, vigas (log beams), turquoise-colored window frames and a circular courtyard reminiscent of Native American spiritual spaces, kivas.

The Moore Studio achieves net-zero energy usage with passive solar design, ‘tuned’ heat reflective windows, super-insulated and air-tight construction, natural daylighting, solar thermal panels for hot water and space heating, a photovoltaic (PV) system that generates more carbon-free electricity than the house requires, and an energy-recovery ventilator (ERV) for fresh air. The green building strategies used on the Moore Studio earned it an amazing and verified HERS score of -3; one of a few houses in the US to ever do this.

Other green building strategies used in the Moore Studio include a grey water system, using salvaged and FSC certified wood, and using low-emission cabinetry and finishes.

This house was featured on the Colorado Renewable Energy Society’s 2010 Denver Area Solar and Green Home Tour and in the videos The Net-Zero Energy Moore House and the Passive Solar Simplified.
