2011 ASHRAE Technology Award: Beyond the Envelope: Restoring a 19th Century Courthouse to Its Original Purpose

Built in the 19th century, the Cowansville Courthouse ceased to be used as a courthouse in the 1990s. Recently, it was renovated and restored to its original function but with new HVAC systems worthy of cutting-edge 21st century construction. Efficient renewable energy systems help the courthouse to save 36% over a standard HVAC system.
