Built from the ground up in 2014 to meet the stringent energy standards of Germany’s PassivHaus Institute, this amazing home at 407 Garden St. is one of the most – if not the most – green homes in Colorado. An ultra-efficient building envelope allows this ingeniously designed home to consume as little as 10% of the energy used by a traditional home of the same size. It’s entirely electric, with electricity consumption offset by a 3.9kW photovoltaic system, making the home a net-zero residence and delivering a HERS rating below 10. Currently 1 bedroom and 1 bath, the home was designed with a 440-sq-ft second floor in mind, which would add 2 bedrooms and another bath (plans included). To top it off, the home sits on a private lot with incredible mountain views and is located just a few steps from the Tucker Gulch walking path, half a mile from the heart of historic downtown Golden. Norm Kowitz will be holding this home open this Saturday, Feb. 24th, noon to 2 p.m. Meanwhile, you can view a narrated video tour of this home and its sustainable features at www.NorthGoldenHome.com, or call Norm at 303-229-3891.
