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.
Technology Review for Carbon Neutrality (Tsinghua University Press) 2025
For racks where GPU/accelerator thermal design power exceeds 1,200 W, take liquid cooling as a mandatory design input, and weigh the initial cost (about 1.9-2.2 times air cooling) against TCO (up to 20% lower after 4 years, vendor figure).
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.
Applied Energy (Elsevier BV) 2025
In data-centre carbon accounting, state the method (Tier 1, 2, 3) and factor source (IPCC or national) when choosing a grid emission factor; simple methods can underestimate generation emissions by about 73%.
Uptime Institute 2009
In the generator catalogue, store the ISO 8528 rating type (COP/PRP/LTP/DCC) and runtime limits.
Open Compute Project Foundation 2021
Give rear-door HX catalog entries rated kW, fan power, coolant inlet temperature, flow, pressure drop and active/passive type.
Vertiv 2020
In the cooling-unit catalog record compressor modulation type (fixed staged, digital, inverter), fan type (EC/AC/VFD), valve type (EEV/TXV, PICV) and control mode (supply or return air).
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.
Data Center Frontier 2025
Model two separate network fabrics (front-end and back-end) in AI hall templates with separate pathways and fiber counts.
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.
arXiv preprint (Cadence Design Systems) 2026
For layout iteration and add-load what-ifs, a surrogate that predicts only cabinet-inlet temperature (the compliance quantity) is cheaper and more accurate than full-field surrogates.
Lawrence Berkeley National Laboratory 2011
When users select airside economization, show a contamination note and suggest coupon monitoring rather than ruling the option out.
Consulting-Specifying Engineer 2022
In the layout checker, flag rows not in hot/cold aisle orientation and missing blanking panels.
Lawrence Berkeley National Laboratory 2016
In small-room projects, present air management in the airflow module as a package: containment, blanking and fan speed control.
Uptime Institute Intelligence 2024
Offer a 'liquid-to-air CDU / sidecar' as a DLC option.
Upsite Technologies blog 2017
Include server fan power rising with inlet temperature in the cooling energy tool (for example about +13% from 68 to 104 F for A3) so set-point optimisation minimises total energy, not PUE.
Upsite Technologies blog 2021
In layout rules, allow perforated tiles only in cold aisles.
Cummins 2014
Add a windingPitch field to the alternator catalog and require 2/3 pitch (or flag) for LV 4-wire generator systems.
Cushman & Wakefield 2026
Use as context only: it supports defaulting to large-campus templates in North American projects.
IEEE 2023
Record controller type and supply-temperature stability (e.g. +/- C) in CDU catalogue entries.
Schneider Electric 2021
Give every network-managed infrastructure device (UPS card, rack PDU, CRAC/CRAH controller, BMS gateway, sensor) catalogue fields for TLS support, RBAC support, IEC 62443-4-2 certification (SL level) and SDL certification.
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.
Energies (MDPI AG) 2018
In airside economiser design, plan exhaust grilles and the building envelope so recirculation stays below 5%; 15% recirculation raised energy about 6.1% for direct and 9% for indirect.
