With prescient timing, Samuel Doyon-Bissonnette, co-president of Unicel Architectural, has recently developed and brought to market a Passive House-certified stick-built curtainwall system using engineered wood. The timing is great because recent changes to codes and standards allow architects to do more with wood construction than ever before. Also, wood answers many questions about energy efficiency and embodied carbon. Samuel discusses the opportunity for wood curtainwall and some of the unique features and challenges of working with this material.
