Kestrel is Boulder County Housing Authority’s new 200-unit affordable housing development on a 13.4-acre site in Louisville, Colorado. Kestrel is a highly sustainable, energy-conscious and water-smart neighborhood. The majority of the buildings are designed as solar-ready, with low-slope roofs and sufficient structural capacity to support photovoltaic panels. All buildings at Kestrel make use of geothermal heat-pump heating and cooling. Using the steady temperatures found deep beneath the earth’s surface, this system is over 25% more efficient than typical heating and cooling systems.
