Net Zero Energy Homes- Habitat for Humanity

energy use budget for each house. Power Use < Power Generation

projected photovoltaic production for each house

First three houses in construction Summer 2014

(27) 300 kw rated solar photovoltaic panels per house.

electric meter has two registers; Solar Input shown here 270 kwh

second meter shows usage; 3 kwh (house not yet occupied)

Dual microinverters feed through Elec panel to meter

Subpanel includes internal energy monitoring systems with uplink.

Water Efficiency- Virga Design

"Virga Design" for a water efficient faucet.

A pivot wand controls Heat/Cool and Flow

Meter shows gallons per minute used and daily usage (resets daily)

Most people are not aware that water saved also represents significant electricity saved, as pumping and water heating represent upwards of 25% of monthly home energy usage.

"Virga" is an atmospheric phenomena where rain can be seen falling from a cloud and frequently evaporating before it reaches the ground.

"Virga Design" is a federally registered trademark

BioDiesel Production Project- Blue Northern

We planted (3) lots for a total of 14 acres with Canola and achieved a decent harvest.

Raw canola oil, like most vegetable oils, through a fairly simple chemical process, can be converted into non-toxic BioDiesel. The relatively clear fluid at the top of the bottle are seperated monolipid Biodiesel from Canola.

Constructed Wetland- Inland Seas Education Association

Constructed a man-made wetland for primary and secondary treatment of facilitity runoff adjacent to a natural wetland which provides tertiary treatment before runoff enters Lake Michigan.

Constructed Wetland

Chris Groebbel PHD- biological/botanical
David Hanawalt- architect

Primary/Secondary wetland for runoff/pollutant mitigation
filters and metabolizes pollutants including petrochemical and heavy metals.
Tertiary wetland is existing natural Suttons Bay wetland
