With the launch of LEED v4, you may have noticed that we changed how we talk about the rating systems. While it can seem a little confusing, we're here to help. Let's take a look at the 2009 rating systems on the left and then filter them through our special v4 lens. Here's what we get:

How LEED 2009 matches up to LEED v4 

Ok, so that was neat! But let's get into specifics:

How many rating systems are there?

There are five rating systems: LEED for Building Design and Construction (BD+C), LEED for Interior Design and Construction (ID+C), LEED for Building Operations and Maintenance (O+M), LEED for Neighborhood Development (ND), LEED for Homes Design and Construction.

Wait, what? Aren't there over ten?

Yes and no. There are still many variations of LEED for different project types, but we've organized them into these five larger areas that reflect the different markets and phases of building life: Building Design and Construction, Interior Design and Construction, Operations and Maintenance, Neighborhood Development, and Homes Design and Construction. Each of the rating systems you were familiar with in LEED 2009 fit into one of these pretty nicely. In fact, you might already be familiar with this structure because it's how GBCI has been organizing certification information for years.

Then did you get rid of rating systems?

No. We just organized LEED to better adapt as the right solution for your project. For instance, in v4 there are two options for school projects: one for Building Design and Construction (BD+C), and one for Operations and Maintenance (O+M). This better addresses the scope of the project and the use of the project.

How do I know whether to use Homes or BD+C: New Construction?

Good question! Here's what the decision tree looks like for this very question:

If your project is a single family home or a multi-family building with LESS THAN 8 floors, you should use Homes or Multifamily Midrise. If your project is a multi-family building with more than 8 floors, you should use LEED BD+C: New Construction.

Is this better?

We think so. We hope this makes it easier for you to figure out which rating system to use. Narrowing it down from five to one seems easier than 15 to one. But we're also trying to make LEED a more streamlined process across projects since they often share the same valuable resources (no more looking for the supplement to the supplement of the reference guide!)

What if I'm still confused?

Do you need a cheat sheet to keep track of all the names and acronyms? (Fun fact: we did.) Here's a version for you to keep.
