IEEE Transactions on Power Systems (Institute of Electrical and Electronics Engineers (IEEE)) 2021
Consider shifting temporally flexible workloads (completable within 24 hours) to hours of lower carbon intensity and lower power peak as an option in data-centre grid-connection negotiation and power capacity planning.
Journal of Engineering Research and Sciences (Journal of Engineering Research and Sciences) 2026
Do thermal verification of failure mode (two ACUs offline) with realistic air leakage (cabinet gaps, HAC panel joints); a leak-free model can comply while the leaky model exceeds 32 °C.
Energies (MDPI AG) 2022
When modelling a server as a porous block in room-scale CFD, use Darcy-Forchheimer coefficients fitted to a resolved pressure-drop curve rather than generic assumptions such as porosity 0.5.
ASHRAE 2022
In site comparison, compute both site WUE and source (grid) water using a regional EWIF, and optionally a scarcity-weighted index.
Vertiv 2025
Add a BESS block to the site model with power (MW), duration (h), reserved-backup fraction and grid/island capability.
Schneider Electric 2014
Capture peak kW/rack and the peak-to-average ratio as well as the average, and express density in W/rack instead of W/m2.
Open Compute Project Foundation 2026
Extend the generator catalogue with technology type (diesel, HVO, gas, H2 ICE, PEM fuel cell), emissions factor relative to the 1742 lb/MWh baseline, start time, block-load capability and NFPA 110 level.
iMasons Climate Accord (Infrastructure Masons) 2025
Add embodied-carbon fields (kgCO2e; data source: EPD / TM65 / spend-based) to catalogue items and roll them up per design, reporting the share from supplier-specific EPDs.
Resources, Conservation and Recycling (Elsevier BV) 2022
In early data-centre design, set PUE and WUE targets by size class, cooling system and climate zone using this study's ranges (for example 1.71-2.22 for small rooms, 1.12-1.25 for large scale).
Uptime Institute Journal 2014
For in-row and RDHx designs, evaluate cooling redundancy per aisle or row, not per room, and check unit throw distance to the farthest rack under N-1.
European Commission 2021
Add an "EU Taxonomy 8.1" compliance profile: a Code of Conduct expected-practice checklist with justification fields for non-applicable items, and a refrigerant GWP <= 675 check in the cooling catalogue.
European Commission / Official Journal of the European Union 2024
In preliminary sustainability calculations, compute PUE, WUE, ERF and REF using the Annex III definitions.
European Commission 2026
As labels will be issued every year from 15 August 2027, set PUE and WUE class targets (Annex I) at design stage for new and existing sites and build the metering infrastructure to the reporting requirements.
European Commission 2022
When validating server PSU data against the 2023 tier, apply an informational exception, not a hard error, for units placed on the market during 2023 (legacy stock).
European Commission 2024
Show in the operations module whether site annual energy crosses 10 TJ (audit) or 85 TJ (certified ISO 50001 energy management system); in unit terms 10 TJ is about 2.78 GWh and 85 TJ about 23.6 GWh.
European Commission 2024
When testing the 1 MW waste heat threshold, compute "total rated energy input" from rated capacity (for example utility connection or rated IT plus infrastructure), not modelled annual energy, and take the measurement point at the handover of electricity supply.
European Commission 2019
In the IT equipment catalogue store PSU efficiency at 10/20/50/100% load, power factor, active state efficiency (SERT/EN 303470) and declared operating class A1-A4, and validate new models against the 2023 tier.
European Commission 2021
In equipment catalogue validation cite EN 303470 (SERT) as the test basis for server efficiency fields and record the declared operating class as tested.
European Commission 2019
In the what-if module show direct and infrastructure savings separately for IT refresh scenarios: the document finds infrastructure savings exceed direct IT savings, which supports showing that every watt saved in IT also saves cooling and power infrastructure energy.
Consulting-Specifying Engineer 2008
Generate a commissioning test matrix from the design: every redundant group should produce test permutations for each lead unit and staging step.
Consulting-Specifying Engineer 2008
For phased builds, the tool should place load-bank connection points and isolation breakers and output a Cx test list with individual, discrete and integrated levels.
IEEE Open Journal of Industry Applications (Institute of Electrical and Electronics Engineers (IEEE)) 2020
Keep bus gap as an input in arc flash calculations for DC panels and battery busbars; do not rely on the maximum-power method alone.
CIGRE US National Committee, 2026 Grid of the Future Symposium (arXiv preprint) 2026
Design data-centre UPS and load control to the most restrictive entity's requirement: 6.0 s ride-through at 0.70-0.90 pu (CAISO), six fault-clearing attempts within 90 s (SPP), six 50-70 ms reclosings (Dominion), and the ban on constant-power control (SPP).
Schneider Electric 2021
Add a protectionControlScheme attribute to the MV module: hardwired_plc_modbus, iec61850_station_bus, iec61850_process_bus.
