Intent
This is a pilot credit. To use any pilot credit on your LEED project, be sure to register here. Documentation requirements and additional questions are listed below.
To minimize the health and climate impacts to local communities from diesel engine emissions associated with construction activities.
Requirements
Develop and implement a plan to reduce particulate matter (PM) emissions from nonroad and on-road diesel fueled vehicles, construction equipment, and temporary power generation used during construction projects. The plan should include:
Nonroad Diesel Engines
For engines used on the jobsite that are 25 horsepower (HP) and greater, meet at least the equivalent of USEPA Tier 2 PM emission standards and the USEPA Tier 4 PM emission standard (or local equivalent for projects outside the U.S.) as listed in the table below for the specified HP rating and during the specified calendar year. The equipment must meet the requirements listed for the current year the equipment is in use on the job site.
Compliance may be met with engines certified to meet the applicable USEPA Tier level, and/or equipment that has been retrofitted with technology verified to reduce particulate emissions to a level at or more stringent than the applicable USEPA Tier level. To the extent that retrofits are used to meet this requirement, the diesel retrofit technology used must be listed on the verified technology list for either the USEPA or the California Air Resources Board (or local equivalent for projects outside the U.S.) current as of the time the equipment is first placed on the jobsite and must be installed and operated as designated by that verified list. Include measures for proper maintenance of the equipment to ensure continued future compliance with the emission standards.Percent of Engines that Must Comply with Tier 4 PM Standard

On-road Diesel Engines
95% of all diesel engine contractor/ subcontractor vehicles used for the construction project must be:- Vehicles that comply with USEPA model year 2007 on-road standards, or local equivalent for projects outside the U.S. OR
- Vehicles with older engines that have been retrofitted with technology verified to reduce particulate emissions to a level at or more stringent than the USEPA model year 2007 on-road standards for particulate matter. To the extent that retrofits are used to meet this requirement, the diesel retrofit technology used must be listed on the verified technology list for either the USEPA or the California Air Resources Board (or local equivalent for projects outside the U.S.) current as of the time the vehicle is first placed on the jobsite and must be installed and operated as designated by that verified list.
Idling Limitations
Develop a policy to limit unnecessary vehicle and equipment engine idling to no more than 5 minutes, or in compliance with applicable local, state and national laws, whichever is more stringent. Include signage and operator communications/education.Prevention of Indoor Air Pollution
Locate equipment, vehicles, and loading/unloading staging areas away from air intakes or operable openings of adjacent buildings.Equipment Information
Include the following information for each piece of equipment, annually:- Vehicle type
- Engine make
- Engine model number
- Serial number of engine
- Engine family name and model year
- Horse power and/or Kilowatts (for nonroad only)
- Current Tier level (for nonroad only)
- Serial number and VIN of vehicle
- Make and model number of USEPA/CARB verified emission control technology, if applicable (or local equivalent for projects outside the U.S.)
- Type of fuel used
- Number of use hours (if available)

What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
