A high bar, but still achievable

This prerequisite is a big one, not only because it’s required for all projects, but also because it feeds directly into the corresponding credit, Optimize Energy Performance. 

What’s New in LEED v4.1

• The ASHRAE version was updated from 2010 to 2016.This means that LEED is now ahead of most local energy codes. 
• Teams must comply with the ASHRAE standard but do not need to exceed it. Requirements to demonstrate improvements between the baseline and proposed building have been removed.
• GHG emissions have been added as a new metric to encourage teams to consider and address project emissions.

• Onsite renewables now count toward compliance in both the prerequisite and the Optimize Energy Performance credit (for both the cost and GHG reduction metrics).

Should I Upgrade?

Upgrading may be a heavy lift, but project teams that upgrade to v4.1 will demonstrate true leadership in energy and greenhouse gas emission performance.
