In this blog post, we provide a rundown of the v4.1 credits that are easy wins, mixed bags, and unanticipated landmines to help you navigate the opportunities for upgrading to v4.1. Remember: for Building Design & Construction Projects (BD+C), you can substitute any v4.1 credit just by choosing that option in LEED Online.

Easy wins

Let’s start with the easy wins. The following credits are great candidates for upgrading to v4.1 because they clarify requirements, offer more flexibility, and open up new compliance pathways.

LTc6: Bicycle Facilities

Relaxed thresholds makes this credit more realistic for projects of all types. The walking distances for short- and long-term storage has been increased, providing teams with some additional design flexibility. Residential projects have reduced thresholds for long-term bicycle storage. Buildings with large occupant populations also get a break in terms of showering and changing facilities. And bike sharing stations now contribute to compliance. While these updates may make the credit easier, we strongly encourage teams to be mindful of building occupants’ needs and potential commuting habits. Don’t shortchange them on bike amenities if they’re likely to want or need them.

LTc7: Reduced Parking Footprint

This credit has been fundamentally re-written and expands the available strategies. New options have been added for no off-street parking, providing parking for carshare vehicles, and for unbundling parking. The reduced parking option has been cleaned up, and the thresholds relative to LTc4: Surrounding Density & Diverse Uses removed, making this option easier to understand and implement. With these new and improved options, there are a lot more ways to earn this point.

SSc2: Protect or Restore Habitat

The minimum thresholds for achievement of both options have been reduced, making the credit easier and less costly to achieve for any project. Additional improvements include revised and clarified soil restoration requirements, and clarifications around native/adapted plant species. Finally, vegetated roofs now contribute regardless of your project’s density.

SSc4: Rainwater Management

The rainfall retention thresholds have been reduced, making the credit much more achievable for all projects. Additionally, the credit language has been cleaned up, and Option 2 (natural land cover conditions) and Option 3 (permeable lot area) were removed, which may help teams focus on implementing best practices rather than slogging through unclear requirements.

WEc3: Cooling Tower and Process Water Use

This credit has two new options that broaden the credit’s scope and give more choice to project teams. These include an option for projects that do not have a cooling tower, and an option that rewards teams for using recycled water for process water uses. Any project that wants to take advantage of these new options should upgrade to v4.1. Core and Shell projects should upgrade if they can meet the requirements for the newly available three-point threshold (found under Options 1 and 3 only). Projects complying via Option 1 should review the results of their make-up water analysis against the requirements in v4 and v4.1 to see how many points are likely to be achieved. Note that, in general, water savings should increase while levels of treatment may decrease as a result of the clarifications to the credit language and the methodology used to document a project’s compliance.

MRc1: Building Life-Cycle Impact Reduction

Several new choices offered under v4.1 could put this credit in reach for a lot more projects. Path 1 is especially helpful as it provides an entryway into LCA for first timers—conduct an LCA, earn a point. Teams that define a baseline and demonstrate improvement will have an easier time reaching the v4.1 thresholds, which have been relaxed in some cases compared to v4.

MRc2: Building Product Disclosure and Optimization - Environmental Product Declarations

Upgrading on this one is a no-brainer since you can, in theory, show reduced environmental impacts, which was impossible under LEED v4. The credit thresholds under Option 2 have been drastically reduced, and project teams can now skip the “by cost” calculation entirely.

MRc3: Building Product Disclosure and Optimization - Sourcing of Raw Materials

This credit has been restructured and is much more realistic for projects to achieve. With a second point now theoretically achievable, and with no limit on structure and enclosure products, an upgrade is definitely worth looking into. You could also benefit if you plan to reuse materials.

MRc4: Building Product Disclosure and Optimization - Material Ingredients

The major changes to this credit align it better with where the market actually is. Hitting Option 1 was already achievable, but stretching to Option 2 is now potentially doable as well. This is a great option for upgrading.

EQc4: Indoor Air Quality Assessment

Structural improvements to this credit make it possible to achieve one point for passing a particulates and inorganic gases test, and a second point for passing a VOC test. Additionally, the list of required CDPH VOCs has been reduced from 35 to just 12. This helps align the credit with the testing industry’s capabilities, and makes it a good candidate for upgrading. While your chances of passing tests are much better, remember that there’s still a risk of having to retest and incur additional costs.

EQc7: Daylight

The thresholds are now more achievable, and we think that providing some measurable daylight to occupants is certainly better than providing none. The maximum ASE requirement has been removed and replaced with the requirement to provide a narrative on addressing glare. Additionally, there are now more points available for higher levels of performance—and in some cases, exemplary performance.

Mixed bag

For this set of credits, upgrading to v4.1 is a mixed bag. The benefits of switching are likely to differ from project to project and can depend on the specific compliance pathway selected. And in some cases, the balance between point achievability and environmental outcomes can be tricky to navigate. We recommend that project teams complete a deeper investigation of these credits before upgrading.

LTc3: High Priority Site and Equitable Development

The new paths under this credit offer great opportunities for bringing green building to the areas where it’s most needed. We’re excited to see how teams approach the new option to develop and implement an equity plan. This credit is a mixed bag if you were planning an infill project in a historic district, since you’ll no longer get LEED points for that choice.

LTc5: Access to Quality Transit

With the new tiers of compliance, you could potentially earn more points. But if you’re relying exclusively on commuter rail or ferry service, you’re going to find the old LEED v4 version of this credit much easier to achieve.

LTc8: Electric Vehicles

Teams that were already planning to achieve credit for preferred parking under v4 should probably stick with that plan, unless there’s sufficient time to pivot to meet the new v4.1 requirements. The v4.1 credit encourages electric vehicle charging infrastructure, which will produce huge environmental benefits over the lifetime of your project—so it’s probably worth investing in. It’s even possible to achieve the credit just by adding the infrastructure for stations without necessarily installing them right now.

SSc3: Open Space

Some projects may benefit from upgrading to v4.1. For example, a project with turf grass or a lower-density building with a vegetated roof will both find that this credit may be achievable under v4.1. Teams that want to claim open space that’s adjacent to the project or in another location within a master plan development should stick with v4.

EAp2/c2: Minimize/Optimize Energy Performance

Upgrading may be a heavy lift, but project teams that upgrade to v4.1 will demonstrate true leadership in energy and greenhouse gas emission performance.

EAc4: Grid Harmonization

This credit includes a new load flexibility and management strategies option, and interested teams should definitely upgrade. Some adjustments have been made to the demand-response program requirements; teams considering DR should review the specifics before upgrading.

EAc5: Renewable Energy

The thresholds for both onsite and offsite renewables are more difficult to achieve. However, the changes to this credit can produce greater benefits to the environment, and so upgrading is worth considering.

MRc5: Construction and Demolition Waste Management

With reduced thresholds available, this credit is much easier to achieve for most projects. However, watch out for that 75% diversion rate that’s new under Option 2.

EQc2: Low-Emitting Materials

There’s no doubt that this credit has gotten far more achievable, so if you’re looking for more points, it’s an easy win. However, it may have gotten too easy. It doesn’t provide the same level of air quality protection that v4 did, given the lowered thresholds for compliance. This change has a particularly big impact for material installers. So if you’re concerned about occupants and tradespeople, we recommend sticking with v4.

RPc1: Regional Priority

Teams should confirm the mix of regional priority credits available under v4 and v4.1 before deciding to upgrade or not.

Unanticipated landmines

Thankfully, there are few unanticipated landmines in v4.1. We’ve identified just one credit that’s an obvious fit for this category. Please let us know in the comments below if your team has come across any other credits to be wary of.

SSc5: Heat Island Reduction

This credit is generally more difficult to achieve no matter which option you’re considering. It’s also not clear whether the updated requirements lead to substantially better environmental outcomes. Teams that want to use LEED Interpretation #5370 or #10411 should consider staying with v4, or confirming applicability for v4.1 projects first. We recommend reviewing the options carefully to determine how v4.1 would impact your specific project.

That's a great tip.

The v4.1 of this credit is an easy win if you were planning on pursuing the v4 option 1 (path that most projects pursue), it removes the requirement for preferred parking which most owners are happy about and keeps the requirement for electric vehicle charging stations at the same thresholds.
