here is a lot of misunderstood information about what we do and require at Flynner Homes with respect to "high-performance" energy efficiency. For instance, we do not push solar panels, geothermal hot water, or any other big ticket items. We can install these items if you desire, but we don't lead with them. Flynner is really about first making the envelope (the exterior parts of your house that come into contact with the natural environment) of your house as energy efficient, and air-tight as possible with minimal costs. We then install conventional, efficient equipment to minimize your utility bills and maximize your comfort and health. The cost of "high-performance" ranges between 1% and 2% of construction costs, and has a return on investment (ROI) upwards of 25% with a pay-back period of 3.9 years.
