SUSTAINABILITY

ENERGY - LEVEL 2

Energy Modeling

• Demonstrate a minimum improvement of 15% compared with a baseline building performance rating. Calculate the baseline building performance according to ANSI/ASHRAE/IESNA Standard 90.1-2010, Appendix G, with errata, using a simulation model. ​

Commissioning (Cx)

• Commissioning services must be complete in compliance with ASHRAE Standard 0-2019, or local code, whichever is more stringent.

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 systems should be upgraded to an all-electric system, where possible. ​

HVAC – Efficiencies

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

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

• For new construction or whole-building renovations, install new or use existing building-level energy meters.​
  
• Install advanced energy metering for any individual energy end use that represents 10% or more of the total annual consumption as determined by the energy model.​
  
• Connect with your Sustainability Director to report monthly energy use data to GPS for tracking towards targets. ​
• Anticipated Sub-Meters include:​
• Lighting
• Plug Loads
• HVAC
• Fans
• Hot Water
• Kitchen Equipment
• IDF / MDF / Computer Rooms
• Processes (e.g.: 3D printers, compressed air, dust collection, tooling)
• Renewable Energy Systems
  

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.​
  

Lighting

• 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

• Use sensors to turn lights off when spaces are unoccupied.

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.​

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

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 PPA



• Connect with the Renewable Energy team on the anticipated energy use of your project so they can include this project in the anticipated consumption when purchasing renewable energy PPAs. ​
