LEED v4.1 BD+C and ID+C Beta
LEED v4.1 is more achievable, providing new options and simpler metrics to help projects reach key outcomes.
The latest energy performance expectations are now recognized, and, for the first-time, reducing operational carbon is explicitly rewarded.
Project teams across the country are adopting the LEED v4.1 credit requirements, using the flexible v4.1 pathways on their LEED v4 projects. See our FAQs to learn how to apply LEED v4.1 credits to LEED v4 projects.
We’ve picked out our favourite updates for you!
Surrounding Density and Diverse Uses – New option allows projects to simply use Walk Score® to be eligible for all the points. Additionally, there is a new option, specific to School projects, where the projects are scored based on connectivity, that is, being connected to previously developed sites.
Cooling Tower Water Use – Name has been updated to ‘Optimize Process Water Use’. Changes allow projects without cooling towers to earn credit under some circumstances, including those whose cooling is provided by district cooling systems, and projects can now be recognized for using recycled water for process use.
Energy Performance – The most exciting change is the explicit addition of carbon pollution from building operations: nine points are now available for reductions in carbon emissions. And it’s worth noting that ASHRAE 90.1 2016 includes some important improvements.
Materials Credits – The changes that have the greatest impact on project teams are within the Materials credits. The restructured credits now include options acknowledging efforts at varying levels, bridging the gap from where the market is currently to the goals identified in LEED v4.
- There are a number of changes throughout the three the credits formerly known as BPDO (Building Product Disclosure and Optimization). Our favourite? Under Sourcing of Raw Materials, Option 1 has moved to the pilot credit library and two points are now available for the more popular Option 2 Leadership Extraction Practices, with a lower entry threshold.
- The holistic assessment of materials is being given a nudge with the addition of new thresholds for completing a whole-building life-cycle assessment (one point) and for achieving 5% reduction in impacts (two points). A 10% reduction is still required to earn three points, but now an extra fourth point is available for incorporating re-used or salvaged materials.
Construction and Demolition Waste Management – The prerequisite has been removed and incorporated with credit requirements. A greater focus is placed on waste prevention, with less focus on recycling.
Indoor Air Quality Assessment Option 2, Air Testing – This option is now split into two paths, allowing project teams to earn one point for testing particulate matter (PM) and inorganic gasses (CO, ozone), and/or a second point for testing volatile organic compounds (VOCs). The number of VOCs tested has been decreased from 35 to 12.
Quality Views - The updated requirements provide an overhaul to the assessment of view types, reducing effort and simplifying requirements - such as by eliminating subjective elements like ‘view factors’ and views of movement.
Multi-unit residential buildings no longer have to choose between different rating systems. The LEED v4.1 Residential BD+C: Multifamily Homes rating system consolidates the requirements for all multifamily projects.
