Schneider Electric 2024
Store the IEC class code (for example VFI-SS-111) and the topology type on every UPS model, and compare models through those fields.
U.S. Environmental Protection Agency (ENERGY STAR) 2026
Map each measure to an efficiency-check rule: missing containment, UPS in double-conversion only, no economizer, and so on.
FacilitiesNet / Building Operating Management 2020
Size UPS autonomy with an end-of-life derating (for example 8 min new, 5-6 min aged) and show both values.

NVIDIA 2025
Add a single-ended 800 VDC distribution option to the electrical model, with rectifier blocks of ~1.5 MVA (LV) and up to 7.5 MVA (MV/SST) and the stated efficiencies.
NVIDIA 2026
Define four electrical templates for AI halls: AC baseline (480 VAC, 100 A whips, 4M3), Power Rack, 2 MW Power Center and 4.8 MW DC Power Block with 4+1 catcher.
Schneider Electric 2015
Build the power-chain calculator as UPS(load) x wiring(load) x PSU(load), defaulting wiring to 1% loss at full load scaling with load squared.
Schneider Electric 2023
Add a lifecycle/opex calculator per UPS fleet: site count, UPS VA, battery chemistry, install-year distribution, warranty, truck-roll cost, staff allocation and downtime $/min.
Energies (MDPI AG) 2023
In UPS designs that only need bridging until the generator starts, evaluate a flywheel as a battery alternative, checking that a 15 s-15 min discharge range and a generator start under 10 s are adequate for the duty.
Energies (MDPI AG) 2020
In Li-ion UPS and BESS areas, set up detection with combined smoke-heat detectors; do not rely on heat detectors alone.
Electronics (MDPI AG) 2025
In efficiency reporting do not make PUE the only metric; knowing its weaknesses (manipulation, optimal-condition reporting, ignoring IT utilisation), complement it with WUE, CUE and IT-side metrics (SPUE, PpW, ITEE).
Eaton 2018
Add charging method (float, opportunistic/ABM, Li-ion BMS) and automatic battery test capability to the battery/UPS catalogue.
Eaton 2012
Provide a power-chain efficiency calculator by stage (transformer, UPS mode, PDU, PSU) including the effect of the A/B load split.
Schneider Electric 2011
In the power-chain efficiency calculator multiply UPS, transformer/PDU, distribution and PSU efficiencies at the actual load fraction rather than nameplate, and offer architecture presets for the five options with Table 1 values as defaults.
Schneider Electric 2011
Add UPS placement (dedicated_ups_room, white_space) to the TCO module and charge room construction ($/ft2 or $/m2, editable by building type) plus occupancy cost for a dedicated room.
Vertiv 2025
Add an AI load-profile object to IT loads (step amplitude %, repetition Hz, duty cycle, peak % of nominal) and use it in UPS and battery sizing alongside autonomy.
arXiv preprint (University of Alberta) 2025
Include rack-level templates for AI racks (32-34 kW air-cooled, 73-132 kW liquid-cooled NVL) with per-GPU power.
Vertiv 2018
Give the battery catalogue chemistry (LFP/NMC/LMO/VRLA), kWh per cabinet, UL 1973 / IEC 62619 listing, BMS level and approved UPS models.
Schneider Electric 2016
Offer reference architectures 'traditional 2N', 'OCP 1N', 'OCP 2N (no central UPS, 1N BBU)' and 'simplified 2N mixed-load (single UPS path)' in the topology builder; let a rack type declare power shelf, BBU runtime and PSU redundancy.
ITEGAM- Journal of Engineering and Technology for Industrial Applications (ITEGAM-JETIA) (GN1 Sistemas e Publicacoes Ltd.) 2021
Choose online double-conversion UPS for loads where power quality improvement is expected; an offline UPS passes harmonics and unbalance through to the load side.
Data Center Frontier 2020
Offer distributed UPS topologies (in-server, in-rack battery shelf, in-row) alongside centralized UPS, with an efficiency and blast-radius comparison.
Springer Science and Business Media LLC (preprint) 2026
When presenting UPS battery autonomy as a way to improve generator reliability, compute the reserve threshold against the mission duration and report that autonomy of minutes adds little to long-outage generator reliability.
Schneider Electric 2022
Add site type (legacy telco, distributed cloud, MEC), environment class and power type (AC, -48 V DC, hybrid) to the project template.
Data Center Frontier 2021
Add HVO and renewable-content diesel options to generator fuel selection with CO2 factors.
Proceedings of the 28th ACM International Conference on Architectural Support for Programming Languages and Operating Systems, Volume 2 (ACM) 2023
Add an hourly 24/7 CFE coverage calculator to site and energy design that sizes wind, solar, BESS (in hours of IT load) and server headroom together; use hourly or sub-hourly supply profiles, never daily averages.
