H & H Industries was involved in the construction of the Dane County Courthouse in 2003. This combination courthouse and jail is located at 215 S Hamilton St. in Madison, WI and houses 18 courtrooms as well as 10 commissioner hearing rooms.

H & H outfitted this building with an advanced air handling system using heated and chilled water to control the air temperature. To distribute the conditioned air, H & H Industries installed a variable air volume (VAV) system which incorporated perimeter heating. This provides comfortable, conditioned air while making the most efficient use of space and energy.

The Dane County Courthouse offers many technological advancements such as sound amplification, voice and video conferencing, wireless networking and real-time transcription.
