EBOM-v4 SSc5: Site management

  • Lots to track and monitor

    This credit comprehensively addresses practices for maintaining your project site. Because this credit covers so much ground, it’s important for teams to thoroughly review all requirements and get a clear understanding of who is responsible for overseeing the different operational areas.

    In some instances, a single requirement may be especially challenging to meet, and may end up being a deal-breaker for pursuing the credit. For example, projects that experience harsh winters may have trouble meeting the deicer requirement.

    Remember to lay the groundwork for this credit by developing a clear and actionable Site Management Policy for SSp1. The policy is an important guidance document for all projects that attempt this credit.

    What’s New in LEED v4

    • Similar to the related site management prerequisite, this credit is derived from two LEED 2009 credits: SSc2 Building Exterior and HardscapeThe inanimate elements of the building landscaping. It includes pavement, roadways, stonewalls, wood and synthetic decking, concrete paths and sidewalks, and concrete, brick, and tile patios. Management Plan, and SSc3: Integrated Pest ManagementIntegrated pest management (IPM) is the coordinated use of knowledge about pests, the environment, and pest prevention and control methods to minimize pest infestation and damage by the most economical means while minimizing hazards to people, property, and the environment., Erosion Control, and Landscape Management Plan.
    • Integrated pest management is no longer included in the SS credit category, and is now covered in the EQ credit category.
    • The credit now includes soil testing, irrigation system monitoring, and materials/equipment storage requirements. There is also a new option for reducing emissions from site maintenance equipment.

    Readiness Review Questions

    • Do you have a mix of vegetation and turf area? If so, can you meet Option 1 by limiting turf area to 25% or less of the total vegetated area onsite?
    • Can the use of manual or electric-powered equipment meet your site maintenance needs?
    • If not, does your equipment meet the 50% emissions reduction threshold?
    • Can you maintain documentation that verifies the requirements for all credit components were met over the performance period (e.g. erosion and sedimentation, landfill waste diversion, deicer usage, fertilizer usage, irrigation system monitoring, etc.)?

    FAQs

    What exactly do I need to track during the performance period?

    The Required Documentation table in the LEED Reference Guide outlines the data and documentation that needs to be collected for the performance period. Table 1 provides additional guidance.  

    Is there a 20% performance threshold like in LEED 2009 SSc2?

    No. The 20% threshold is no longer available. 

    If all of the onsite landscaping is done by a contractor that only uses 100% electric equipment does the contractor need to document the maintenance of the equipment for the credit to be achieved? They have many items that are the same and so they do not keep track of which specific mower was brought to the site, for example.

    No, the contractor does not need to document the maintenance of the equipment. Provide a total inventory of the contractor's equipment (this could be a list, copies of the manufacturer's info, or anything showing the type of equipment they use and power source. Of course, the inventory is just a snapshot in time. Ensure that substitutions are also electric.

  • SS Credit 5: Site management

Glisofat

Project Location: Spain

There are contradictory studies related to the use of glisofat as a herbicide. Would spraying with a mixture containing 30% glifosat be an aceptable practice?

I searched for Glyphosate (seemed like the closest option to glisofat) using the PRI PestSmart tool and it's coming up as Tier I (http://pesticideresearch.com/site/pestsmart/). So, I think it'd be best practice to be judicious with how/where you apply it, and you should likely test out some other options before wholly adopting it for ongoing use.

Zero lot line

Can a zero lot line building achieve this credit?

Hi Lawrence,

I don't see any precedence that would keep a zero lot line building from achieving this credit and the performance requirements don't list a specific site area or landscaping requirement like you see for the site management plan. A general rule of thumb is that avoidance is not compliance. If you can illustrate that most of the performance criteria can be met such as appropriate deicers at your entrances, low emitting equipment is used (blowers at entrances, window washing equipment?), then I don't see an issue. If you find that most of the performance items are not applicable to your site, this would be an indication that you may not be able to pursue the credit.

I also wanted to add that the second bullet under Step 4 in the Reference Guide states that Option 2 is a good path for "sites with minimal maintenance needs" and offers zero lot line buildings as an example.

Monitoring and Inspection of Irrigation System

For SS Credit Site Management, the performance requirement says: "Monitor irrigation systems manually or with automated systems AT LEAST EVERY TWO WEEKS during the operating season and correct any leaks, breaks, inappropriate water usage, or incorrect timing."
In Table 2 under the same credit on Further Explanation Section, Irrigation Management, inspection of irrigation should be AT LEAST TWICE PER YEAR.
Is Table 2 statement correct? Should inspection be part of monitoring process?

Hi Ryan,
The table you are referring to in the further explanation section of the reference guide, helps to explain the different tasks that need to be completed and at what frequency.

It states that the team must perform routine leak detection during operating season by taking irrigation submeterSubmetering is used to determine the proportion of energy or water use within a building attributable to specific end uses such as tenant spaces, or subsystems such as the heating component of an HVAC system. readings every two weeks or using an automated leak detection system.

The next bullet down states that a full inspection of the irrigation system including leaks, breaks, irregularities in water usage, and system time settings, must be done twice a year.

The way I distinguish these two requirements is, the first is simply ensuring that there are no leaks in the water system every couple of weeks by checking the water usage readings for irregularities. The second is a deeper dive where you would likely walk the site and check on the irrigation system to see if there are any leaky heads, or other issues with the functioning of the system.

Although it is not very clear, I think these two tasks can be separated into the two buckets above.
I hope this helps!

Approved Deicers

Project Location: United States

Hi Sam,

I've been looking at deicers appropriate for this credit. After some chemicals were removed from the environmentally friendly list in the reference guide via the July addenda, I see calcium magnesium acetate (CMA) is the only one left. I've read CMA has a few downsides, but certainly not as bad as the salts/chlorides.

I've looked into some other products containing the following ingredients: Urea (Carbonyldiamide), Propylene Glycol, and Amides. Are you aware of any problems with these chemicals?

We are looking to use sand or something else for traction on ice, but it's not mentioned in the reference guide. Not sure if LEED has a stance on that as well?

Thanks,
Stephanie

Hi Stephanie,

I haven't heard of these three particular products being called out for an inability to use them on LEED projects. As the Site Management credit language specifically notes "use no calcium chloride or sodium chloride deicers..." if you're avoiding these products and the three products recently struck from the list of preferred types in the policy, I think you'll be safe. If the main ingredient in the items containing Urea (Carbonyldiamide), Propylene Glycol, and Amides happens to be CMA, I think it would only strengthen your argument.

I also have no heard specifically about an inability to add sand for traction purposes, but this may cause sedimentation concerns, complicating another portion of this credit for you. If there are strategies in place to ensure you're not allowing sand to leave the site and are disposing of it properly, this could put you in a better position.

Option 1: Limited Turf Area

Project Location: United States

Hello - the site I'm looking at already has under 25% turf area. In fact it has no turf, only vegetation. According to a different credit (Site Improvement Plan) there is a 5% min vegetation requirement. It is well above the 5% requirement. Since the site won't need any modification to meet Option 1, would this project still be eligible to receive the 1 point for not having turf? The maintenance equipment plan is being kept up to date for the performance period. Any insight is appreciated.

Hi Stephanie,

Since your site currently has less than 25% turf, you meet Option 1 and are compliant for this portion of the credit. It's not avoiding the credit compliance in any way, just being lucky enough to have it checked off your list early. I don't see any issues with your project achieving this point.

Thanks,

Sam

Required Documentation: All Projects for Site Management credit

Hello,
Is there an example of an acceptable "air quality protection log" that USGBC is looking for in this credit?

Hi John,

I don't believe there is an example log available from the USGBC, but I would recommend creating a log that allows for checking, writing notes/ remediation actions, and providing a photo to document strategies in place for construction erosion and sedimentation practices in the SS policy as well as appropriate materials and equipment storage practices, all of which will contribute to air quality protection.

What are the baseline conditions?

Project Location: United States

This says we have to reduce from the baseline, which I assume is our initial reported use. However, if this is the case how can there be any reduction? Is it suppose to read something along the lines of have a proposed reduction of ... or is there something else I'm missing here?

Hi Zachary,

Option 3 does require some changes to be made to current operations to achieve emissions reductions. Using the equipment emissions reduction calculator provided by the USGBC (link in comment below), enter all equipment types and time of use currently in place at the site to set the baseline. You will thenl need to switch out equipment or reduce time spent with high emission equipment to achieve the necessary reductions.

Hope this helps.

Option 3: Determining HC and NOx emissions

Project Location: United States

Although an Equipment Emissions Reduction Calculator is provided, how do we address maintenance vehicles used on site? The calculator only accounts for equipment but wouldn't a pressure washer and sweeper need to be included in these calculations as well? Or are vehicles exempt? If they are not, how do we calculate the input values?
I appreciate any guidance! Thank you!

Hi Michelle,

Vehicles are the only "equipment" that are noted as excluded. They reference trucks used for snow removal as an example. Therefore, I believe all other maintenance equipment used to clean and maintain the site should be included in your calculations. I would try to find the best match provided in the calculator for each missing piece of equipment. Their primary concern is anything utilizing gasoline. If a close match does not seem possible, you may use the "other" selection listed in the updated copy of the calculator found here: http://www.usgbc.org/resources/equipment-emissions-reduction-calculator
