The document summarizes changes between LEED v2009 and LEED v4, which was released in 2013-2015. Key changes include more rating systems covering different building segments, an increased focus on location and transportation factors, water and energy use reduction, protection of habitat, renewable energy, and enhanced commissioning. New concepts include managing rainfall on-site and addressing light pollution, demand response programs, and acoustic performance. Material selection requirements were strengthened around disclosing ingredients, life cycle assessment, and corporate sustainability reporting. Indoor environmental quality criteria for VOCs and daylighting were also increased.

4. High level structure remains
• 100 base points + 10 ‘bonus’ points
40-49 50-59 60-79 80+

5. Integrative Design
• New stand alone credit
• Found in both BD&C (1 point) and ID&C (2 points)
• Must include both energy and water systems
Integrative Design Process
Owner’s
Project
Schematic Design Construction
Requirements Cx
Design & Basis of Document Documents

6. Location & Transportation (LT)
• Was a credit category in v2009 ND and HOMES
• Will be rolled out to all rating systems in v4
• Credits moved from Sustainable Sites (SS) which is
now dedicated to on-site issues:
BD&C EB:O&M
Site selection Alternative transportation
Nearly amenities / densities
Brownfields
Access to transit
Bike facilities
Minimum parking
Low emitting vehicles

7. Location & Transportation (LT)
Rideshare as Transit
• Rideshare locations considered transit
Bike Network
• access to 10 diverse uses or a transit stop located 5km
Parking Reduction
• reduce by 20% below a baseline if no access to transit and low
density area, or by 40% if near transit or a high density area.

8. Utility Consumption Reporting
2 new prerequisites (Building-Level Water
Metering, and Building-Level Energy Metering)
require 5 years of reporting to the USGBC

9. Water Use Reduction
• application and process water now included

10. Energy Use Reduction
EB:O&M
• Energy star minimum score is now 75 (up
from 69)
• 20 points now available (up from 18)

11. Big Changes
Protect / Restore Habitat
• Now available via 100% off-site lands
or financial donations
Renewable Energy Systems
• Off-site systems can contribute if in same utility district
Commissioning of Building Envelope
• Enhanced Cx (credit) now requires additional systems
Construction Waste Management Prerequisite
• Plan and report; no performance requirement (for prereq)

12. New Concepts
Rainfall Management
• v2009: statistical ‘worst case’ precipitation event
• v4: management of 95th percentile of annual rainfall
Data Centres
• Required in energy model (5% better than baseline) and
commissioning
Site Assessment
• One credit available for documenting site topography,
hydrology, climate, vegetation, soils, & human uses

13. New Concepts
Light Pollution
• prescriptive requirements use ‘BUG’ classifications
(Backlight, Uplight, Glare) for exterior fixtures
Demand Response Management
• Participate in a utility demand response program, or
• be ready to partake in one when/if made available, or
• permanently shift 10% of load from peak to non-peak times
Acoustic Performance
• Previously included as a credit in LEED Schools, a credit is
now included in BD&C

14. Material & Resources
Environmental Product Declarations (EPDs)
• Disclose ingredients, extraction and manufacturing
• Awarded regardless of performance
• Based on the number of materials reported (not cost)
• Additional points if less-harmful
Whole Building Life Cycle Assessment
• Structure and enclosure measured against reference model
(similar to energy simulation), in 6 categories
• Must be 10% better 3 categories, and no more than 5%
worse in any category

15. Material & Resources
Corporate sustainability reporting
• Credit awarded to producers who report
• Additional point if report is third party verified
Bio-based (not ‘rapidly renewable’)
• New option for agriculture-based materials
• Uses the Sustainable Agriculture Network (SAN) standard
Regional extraction, processing and manufacture
• No longer sufficient for credit on its own
• Will count towards an extra point if compliant materials
are also regional

16. Indoor Environmental Quality
Low VOCs
• Now applies to all materials (not just wet applied)
• Requirements for off-gassing over time (+ for wet apply)
• More points per compliant category (ceilings, floors, furniture, etc)
Daylighting
• Worth up to 3 points (up from 1)
• Requires simulation (or 1 point for measurement)
Views
• 2 points (up from 1)
• Reduced from 90% of regularly occupied area to 75%
• Additional requirements to ensure quality views

Language added throughout all rating systems
