DC SUSTAINABILITY

ENERGY - LEVEL 3

Commissioning (Cx)

• If the project includes upgrades to mechanical, electrical, plumbing, or renewable energy systems, commissioning services must be in compliance with ASHRAE Standard 0-2019 or local code, whichever is more stringent.

OPTIONAL: HVAC – Electrification

• For projects installing new HVAC equipment, ensure that the grid and electrical infrastructure can support electrification. Life cycle costing should be utilized to determine whether the HVAC equipment should be fully, partially, or not electrified.
• Give preference to choosing all-electric building(s) for the project. Base-building HVAC system should be upgraded to an all-electric system, where possible. 

OPTIONAL: HVAC – Efficiencies

• HVAC efficiencies for all newly installed equipment should meet or exceed the minimum efficiencies defined by ASHRAE 90.1-2010 standards
  

OPTIONAL: HVAC – Refrigerants

• Comply with LEED prerequisite Fundamental Refrigerant Management
• Comply with LEED credit Enhanced Refrigerant Management where possible*
• For projects that are installing new HVAC&R equipment, prioritize selecting equipment that uses no refrigerants.
• If refrigerants will be utilized in the HVAC&R equipment, ensure that they comply with one of the following two options:
• Have an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) < 50
• Select refrigerants that minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change. Calculations should be performed in accordance with the LEED requirements 

* Preference should be given to selecting a building that has no/low refrigerant impact. If the building is owned, the base-building HVAC&R system should be upgraded, when possible, to a hydronic-based system or a system that minimize the emissions of compounds associated with ozone depletion and climate change.

Metering

• Use existing tenant-level energy meters where possible
• Connect with your local sustainability champion to report monthly energy use data for tracking towards targets
  

Building Automation System (BAS)

• Install a BAS from a Nike preferred supplier. The system should be a complete system designed for small stand-alone use to large, networked systems. 
• Devices residing on the enterprise IT network should be fully IT compatible device that mount and communicate directly on the IT infrastructure in the facility
• Contractor should be responsible for coordination with the owner’s IT staff to ensure smooth functioning and installation of BAS
• Compliance with ASHRAE/ANSI/EIA standards is recommended

OPTIONAL: Energy Management System (EnMS)

• Implement an EnMS
• DCs should establish ownership of key energy-related tasks and the proper communication channels between ownership to implement an effective EnMS
• It is recommended to follow ISO 50001 Standard for the EnMS

Lighting Efficiency

• Utilize high-efficacy LED luminaires and design spaces to comply with the max lighting power densities (LPDs) shown in the Table*
• Systems must be flexible and allow for reconfiguration for ease in maintenance
• Spaces should be evaluated by the lighting designer on a project-by-project basis and some spaces may not be able to comply depending on specific project needs

* The LPDs in the Table are a guideline and should be used wherever possible. Where the local code is more stringent or conflicts with the requirements, local code should take precedence. 

Lighting Controls

Daylighting Harvesting

• Use daylight harvesting for spaces with natural light. Program in zones, with timers set to avoid frequent changes from clouds, etc. 
• OPTIONAL: Allow user override to turn off lights
  

Vacancy or Occupancy Sensors

• Provide sensors within warehouse aisles to automatically dim lights by at least 50% after 15 minutes of inactivity during business hours
• Sensors should be located to provide complete coverage of the aisle
• Alternatively, luminaires with integral sensors can be used to provide this functionality while reducing the need for additional wiring and conduit for separate control devices

Dimmers

• Dimmers and controls must be simple and intuitive
• Dimmers should set a high trim for maximum brightness. Designers should target high end trims to be no less than 80% of full output.

Photosensor controls

• Provide photosensor controls for exterior lighting such that the exterior lighting is turned off during daylit hours.

OPTIONAL: Timers

• •Timers can be used to turn lights on/off at designated times. Manual timers plug into an electrical outlet to manage lamp or light strings; more advanced timers can be built into the wall (similar to a thermostat) to automate lighting.

** Where the local code is more stringent or conflicts with the requirements, local code should take precedence. 

OPTIONAL: Equipment

• Projects installing new kitchen equipment should evaluate whether the grid and electrical infrastructure is able to support the installation of all-electric equipment by utilizing life cycle costing to determine what equipment should be electric. 
• Installing electric ovens, fryers, griddles, broilers, steamers, and dishwashers should be prioritized
• Installing electric ranges, grills, and hot water heaters should be considered and determined whether feasible on a project-by-project basis
• New refrigerators and freezers should utilize natural or lower GWP refrigerants wherever possible
• Install ENERGY-STAR certified equipment (or local equivalent) for the products located in the table
• In Europe, install equipment with an EU energy label, targeting products that have a Class A or B rating
  

Renewable Energy Assessment

• A renewable energy assessment should be completed to evaluate if the location is a good candidate for wind, solar, or both. If a building is a good location for solar or wind, the facility must assess which type of solar (i.e. rooftop, array, or flowers) or wind turbines are best to utilize. For new facilities, it is best to do an RE assessment early in the design and construction process to ensure no rework will be required to provide necessary interconnection points.

Renewable Energy PPA

• Refer to the Nike Guidance for Renewable Energy in LEED Applications and confer with the Renewable Energy team as needed to obtain renewable energy credits for your project and gain credit under LEED.
• Through Nike’s renewable energy LEED Volume Portfolio, all owned and operated facilities in the US and Europe can automatically capture six (6) LEED points
• Owned and operated facilities outside of the US and Europe can utilize Nike’s existing unbundled renewable energy credit (REC) purchases, currently in 15 countries
• Facilities which are leased, should confer with the Renewable Energy team to obtain REC purchase receipts to include in LEED applications   
• A small number of countries have no or partial renewable energy coverage and the purchasing of RECs should be looked at on a project-by-project basis
