LEED v4.1 BD+C and ID+C Beta is Now Available
In a market that is constantly evolving, one of the hallmarks of LEED is continuous improvement. Registration is open for the beta versions of LEED v4.1 BD+C and ID+C.
LEED v4.1 helps project teams meet changing market conditions, including updated energy performance expectations and code requirements, and a growing recognition of the critical importance of addressing carbon pollution. The draft rating systems provide new options and paths for project teams.
We’ve picked out our favourite updates for you!
Access to Quality Transit – More thresholds are now available and weekend trips can be the higher of Saturday or Sunday, rather than the average. This is particularly beneficial for projects outside urban centers.
Cooling Tower Water Use – Changes allow projects without cooling towers to earn credit under some circumstances, 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 will 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 Building Product Disclosure and Optimization credits. 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.
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.
