MRc2 Option 2: Multi-Attribute Optimization
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!

Requirements for MRc2 Option 2 in LEED v4 and v4.1
To earn one point for Multi-Attribute Optimization, you need to use at least 5 permanently installed products that comply with one of the criteria we’ll discuss shortly from 3 different manufacturers.
- Life Cycle Impact Reduction Action Plan (value at 50% by cost or ½ product)
- Life Cycle Impact Reductions in Embodied Carbon (value at 100% by cost or 1 product)
- Life Cycle Impact Reductions in Embodied Carbon - 10% reduction global warming potential (value at 150% by cost or 1.5 products)
- Life Cycle Impact Reductions in Embodied Carbon - 20% reduction in global warming potential and 5% reduction 2 other impact categories (value at 200% by cost or 2 products)
And that’s the cliff notes version. The full language will have you mispronouncing eutrophication, learning about tropospheric ozone, and pounding bourbon like you’re Al Swearengen.
So what does any of that mean? Let’s try and break this down in plain English. You need 5 permanently installed products from 3 different manufacturers. These products need to either have a plan in place to reduce lifecycle impacts OR show some actual reductions. Download the ebook to see what this entails.
