A credit that was dead on arrival in LEED v4, Multi-Attribute Optimization, now has a very slight pulse in LEED v4.1. The credit thresholds have been re-written so that only 5 products are needed, and there’s actually a confirmed standard to demonstrate compliance. The challenge that remains? There are still only a handful of these products, so you better plan on using all of them and have them identified from spec to installation. There’s literally no room for error!
