Sustainable DesignT3 FAT Village is Florida’s first large-scale mass timber Class AA sustainable office building. Optimized energy performance, low-carbon-emitting materials and enhanced daylight features are among the sustainable features beyond the mass timber itself. Crews applied temporary waterproofing membranes and drainage measures to protect the mass timber structure during South Florida’s rainy season. “Mass timber buildings leave timber exposed and have no ceilings.” Because mass timber structures are “inherently lightweight,” mitigating acoustic transfer that can cause unwanted noise may be necessary, Cavanaugh adds.
