Basalt Library

Basalt, CO

The Basalt Library, a recent Sol Energy civic project, demonstrates how photovoltaics can enhance the sustainability of a building while contributing to its educational function and strong design aesthetic.

Sized at 76 kW, the PV system will produce an estimated 95% of the building’s electricity, offsetting approximately 200,000 pounds of CO2 each year. A monitoring system located in the entrance lobby increases public awareness of solar energy while providing first-hand data and information. Visitors are able to track current power output, energy generation over time, solar irradiance, and more.

The photovoltaic system is one of many ecologically responsible components of the Basalt Library. Other features include recycled and locally sourced materials, efficient windows, high levels of insulation, advanced lighting and HVAC systems, and daylighting. As the Basalt Library applies for Leadership in Energy and Environmental Design (LEED) certification, the PV system will likely play a key role in its designation.

The photovoltaic arrays are an integrated and attractive design feature of a building known for its beauty and stunning architecture. Two-thirds of the panels are flat-mounted on the south-facing angled sections of the roof. The remaining panels, located on the flat section of the roof, are arranged in a series of arrays tilted to match the exact angle of the slanted roofs. The effect is beautifully symmetrical and reinforces the building’s overall design.
