Nearly every energy conservation measure possible has been applied in this green home in order to reach the zero energy goal. The remaining heating and cooling are provided by a geothermal system. The project has received city approval and is seeking state approval for a greywater and rainwater harvesting system that will be used both for toilet flushing and irrigation. The inverted roof visible in the rendering is designed for rainwater collection, but also cleverly hides the solar hot water and solar electric panels that round out the energy approach. This is a nice example of a design statement and two different performance goals all working in tandem.

The home is seeking Chicago Green Homes certification, starting with a variety of energy-efficiency strategies. The existing walls will be insulated with soy-based spray foam insulation, and a geothermal system will provide heating and cooling. As in many green homes, clerestory windows at the top of a central light and air shaft open to provide natural ventilation. Here, though, the windows will open and close automatically in response to a temperature sensor. Similarly, window shades will raise and lower automatically in response to daylight. These features and more will be controlled by a computer-based building automation system, typically only seen in commercial buildings.

This a project designed by an architect as his own family residence. It is another example of a budget-conscious but reasonably responsible design. Most of the green investment goes into energy-saving, but easily achievable features - rigid exterior insulation with spray foam insulation between studs, high-efficiency mechanical systems, and an Energy Star roof.

The Orchard Residence is a 9,700 sf, 3-story plus basement single-family home currently under construction (6,600 sf with basement and garage). This is the largest home we’ve covered yet and is certain to raise some eyebrows because of the materials and energy consumption associated with such [...]
