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 Energy 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.
