Learning Objectives

At the end of this webinar, you will be able to describe these aspects of LEED for Homes v 4.0:

• 1. The timeline for the roll-out.
• 2. The certification process and tools.
• 3. The major changes in the prereqs and

credits.

• 4. Generally, how projects will score.
• 5. Where to learn more.

Agenda

• 1. Overview- Summary of Changes
• 2. Process Changes
• 3. Rating System Changes
• 4. Example Applications
• 5. Summary / Wrap Up

• 1. Overview

• Raise the Bar
• Rapidly changing codes
• Align Requirements
• Between single family and multifamily
• Homes and NC
• New Market Sectors
• Mid-rise residential projects. (Required for 4-8 Story Projects)
• New Impact Categories (used for credit weightings)
• Climate change, human health, water resources, biodiversity, green

economy, community and natural resources.

Why Change?

• Improved Tools and Resources
• Step-by-step reference guide materials with videos and tutorials,
• Improved technology platform.
• Eliminate paperwork heavy credits
• Removed Durability Evaluation and New Durability Checklist
• Removed Accountability Forms
• Removed MR 1.1 Prereq: Framing Order Waste Factor
• Focus on Performance Based Credits w/ Consumption Metrics
• Water Budget, Metering
• Energy Budget, Metering, Utility Tracking

Rating System

Basic Structure General Changes

• 1. 110 Points Total (from 136)
• 2. Credit names are familiar
• 3. Order (numbering) is very different
• a. Prereqs are pulled out front (p1, p2,

etc.)

• b. Credits follow (c1, c2, etc.)
• 4. Single Family, Low-Rise and Mid-Rise are

Combined.

• 5. Bottom Line: Projects will lose one

certification level.
