The Louisville Northeast Regional Library, the latest addition to Louisville’s library system, exemplifies cutting-edge sustainable design and cost efficiency. Faced with the challenge of exceeding the energy and cost performance of its predecessors, the project team implemented 53 Solatube SkyVault M74DS tubular daylighting devices (TDDs). By replacing traditional clerestories with these advanced daylighting solutions, the library achieved a dramatic reduction in electrical usage—from 1.02 to 0.65 watts per square foot—resulting in substantial energy savings and a $249,765 reduction in structural steel costs.

For industry professionals, this project highlights the benefits of integrating advanced daylighting technology into large-scale public buildings. The library’s innovative use of Solatube TDDs not only enhances aesthetic appeal, focusing on biophilic design but also delivers significant operational cost savings, setting a new benchmark for sustainable design in community spaces.

Dr. Neall Digert, Ph.D., MIES, Vice President of Innovation and Marketing at Kingspan Light + Air | North America, is available for interviews or byline contributions to discuss the project’s impact on sustainable architecture and innovative daylighting solutions, highlighting the benefits of biophilic design. Please let me know if you have any questions.
