Spring Leaf is one of the nation’s first multifamily net-zero-energy developments. The project is currently under construction in Boulder, Colorado.

Drawing on solar and geothermal energy, and featuring sustainable building products and healthy interiors, Spring Leaf offers 12 custom-designed homes that will exceed LEED-Platinum certification, the highest green-building standards in the U.S. Each home produces more energy than it uses through a combination of passive solar design, geothermal heating and cooling, and solar photovoltaics.

Blue Valley Heating & Cooling has completed the heating and cooling for the first of twelve units built. The system features a WaterFurnace geothermal heat pump, a state-of-the-art zoned duct system, and ECM fan-based heat recovery ventilation.
