Environmental Research: Energy (IOP Publishing) 2025
Calculate AI training cluster energy and power demand from measured node power (here 7.3-7.79 kW in training, 76% of TDP) rather than TDP; a TDP-based estimate inflated a 20,000-GPU cluster by 19 GWh.
arXiv (preprint, submitted to IEEE) 2026
Store operating-mode behaviour in the UPS catalogue and electrical model: eco-mode availability, transfer thresholds and timers (for example 0.7 p.u./20 ms to battery), and a post-event rectifier ramp time.
International Energy Agency 2025
Use the IEA component split (servers about 60%, storage about 5%, network up to 5%, cooling 7-30%) to sanity-check modelled energy breakdowns.
Siemens 2020
Check busway Icw/Ipk against the prospective fault level at the feeding board.
U.S. Environmental Protection Agency (ENERGY STAR) 2022
Catalogue entries for storage should carry ENERGY STAR status, PSU efficiency curve points (20/50/100%) and power factor, so the rack power model can derive input power and heat from IT load rather than nameplate.
U.S. Environmental Protection Agency (ENERGY STAR) 2016
Network catalogue items (ToR and spine switches) should store ENERGY STAR status, PSU efficiency points and measured power at idle, VLU, 30% and maximum load so rack heat loads reflect real utilization.
U.S. Environmental Protection Agency (ENERGY STAR) 2017
Store efficiency at 25/50/75/100% load for each normal mode (double-conversion, eco/ESS) in UPS catalogue entries, measured to IEC 62040-3.
Burns & McDonnell 2025
Add a BESS catalogue type with chemistry, MW, MWh, connection voltage and UL 9540A test reference.
ACM e-Energy '26 (author version on arXiv) 2025
Add a ride-through check to the electrical module: compare the selected UPS input tolerance (IEC 62040-3 class) and IT tolerance (ITI/CBEMA) against the applicable grid-code LVRT envelope for the site's region, and flag the gap.
arXiv preprint (Black & Veatch / University of Central Missouri) 2025
In gigawatt-scale data-centre interconnection studies, add the load-loss scenario from IT load transferring to UPS in a voltage dip (for example 5 × 200 MW with a 1:1 split giving 500 MW) to the grid frequency and voltage analysis.
EPRI (Electric Power Research Institute) 2026
In the electrical/grid module, let users declare a flexible-load capability (curtailable MW, duration, ride-through via BESS) for interconnection studies.
Executive Office of the President / Federal Register 2025
Check the 100 MW new-load and $500 million capex thresholds early to decide whether a US project can use the federal streamlining.
Batteries (MDPI AG) 2025
In LFP module design, evaluate inter-cell thermal resistance (interface insulation) together with measures that cut heat release to stop propagation; in the model an interface resistance of hR = 100 W·m^-2·K^-1 alone suppressed it.
Batteries (MDPI AG) 2026
For confined battery packs and cabinets, evaluate a fast flame-knockdown agent (such as heptafluoropropane) together with an agent or approach giving long-lasting cooling (such as perfluorohexanone); no single agent stopped heat transfer to neighbouring cells.
Schneider Electric 2018
Battery catalog: chemistry (VRLA, LFP, NMC, LMO, NCA, LTO, LCO), specific energy, design and cycle life, rated temperature, footprint and weight per kWh, recharge time and compatible UPS models.
IEEE Access (Institute of Electrical and Electronics Engineers (IEEE)) 2025
For a UPS that will provide grid services, define the SOC window (for example 20-80%) and show by calculation that backup autonomy is preserved inside it.
Consulting-Specifying Engineer 2025
Make pre-action (single or double interlock) with aspirating detection the default white-space suppression option; keep clean agent and water mist selectable.
arXiv (Aalborg University) 2026
For large sites, capture grid-code inputs per jurisdiction (FRT curve, MW/min ramp limit, power-quality limits) as project inputs and flag UPS settings that transfer to battery or generator on shallow sags.
IET Generation, Transmission & Distribution (Institution of Engineering and Technology (IET)) 2026
For large or AI facilities, record the UPS's fault ride-through behaviour (momentary cessation versus ride-through with minimum grid draw), the inverter current limit and the post-fault ramp rate, alongside the point-of-interconnection short-circuit ratio.
arXiv preprint (Stanford University / Microsoft Azure Research) 2026
For an AI inference facility, set interconnection capacity from traces generated from the workload, not nameplate TDP or mean power; TDP sizing gave 1.19 MW against 0.75 MW trace-based (about 60% too much).
Energy Advances (Royal Society of Chemistry (RSC)) 2025
For UPS duty with a few cycles a year and minutes of autonomy, compare battery chemistries by environmental impact categories (GWP, ecotoxicity, resource depletion) as well as energy density, because production and EOL dominate.
Siemens 2021
In the MV switchgear catalogue store insulation {AIS, GIS}, arc-resistance standard and rating, inspection interval and footprint.
CBRE 2025
In the site module, store local power and planning caps (for example Amsterdam 70 MW IT) as site-rule warnings.
IEEE Access (Institute of Electrical and Electronics Engineers (IEEE)) 2026
Require block-level (per-unit) voltage and resistance monitoring in UPS battery monitoring rather than string totals, citing that one weak unit in a series string limits the whole string's capacity.
