Among the most innovative of the home’s green features is the use of insulating concrete forms (ICFs). According to the Insulating Concrete Forms Association’s website, the use of ICFs results in sturdier, quieter, more energy efficient homes. Instead of being made of wood paneling like traditional houses, ICF homes are built with concrete containing two layers of insulation, and are built to withstand the damages of fire, wind and time. The use of ICF should result in lower heating and cooling expenses.

1840 N. Leavitt is an example of the jumbo-sized home that works to counteract its large size with a variety of green measures. An existing 100 year old multi-unit residential building being converted to a single family residence. The project is seeking Chicago Green Homes and Energy Star certification.

The Heppner Residence is an example of extreme do-it-yourself green renovation. This existing 100 year-old wood frame single family home is being rebuilt by Tim and Charles Heppner, two brothers, with Tim acting as architect and performing most construction work himself. The Heppner brothers are seeking Energy Star and Chicago Green Homes certification for their new home.

1314 N. Moorman is a 2,600 sf (3,600 sf with basement) speculative single family green home with many basic energy efficiency features and a bit of ‘green bling’.

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.

Chicago Green Homes (CGH) is the city’s green certification program for small residential projects. Most of the concepts are similar to LEED®, but whereas LEED® is fairly performance-based, requiring a certain amount of research and calculation to demonstrate compliance with each credit, Chicago Green Homes is more prescriptive, which is easy for small projects to use.
