Case Study: Improving Energy Efficiency and Preserving History

The solution to reducing our country’s energy demand and consumption is a combination of efforts. In addition to new construction using the latest energy efficient techniques and materials, upgrading existing housing and building stock with state-of-the-art, energy efficient windows ranks high in improving energy performance.

Bisbee, Arizona, City Hall. Window replacement in historic buildings presents challenges unique to those in new construction. This spring, 75 custom-size, single hung Andersen 100 Series® windows were installed in Bisbee’s historic city hall. Due to availability of custom sizing, the contractor was able to remove the existing wood window inserts and leave the original frames in tact. This flexibility helped maintain the building’s aesthetics by preserving its historic trim while improving energy efficiency.

Preserving a building’s authenticity is often paramount in historic renovations, even trumping energy efficiency in some cases. Juggling code requirements for these structures, while capitalizing on new energy efficient technologies, has been tricky in the past. However, with the versatility of Andersen’s new 100 Series line of windows and patio doors, custom sizes and installation options allow for improved energy efficiency and historic preservation.
