Schneider Electric 2011
Record the cord count (single or dual) of each IT device in the rack model and compute the single-corded share.
Data Center Knowledge 2018
Model the campus as power blocks with block-level MEP independence and fire zones.
Fire (MDPI AG) 2026
Ask for a fire-safety design file that covers a lifecycle plan (aligned with NFPA 75 and NFPA 76) including emergency response, damage control and post-fire recovery, not only prevention and suppression.
Energies (MDPI AG) 2023
When choosing among DRUPS or UPS configurations, first screen with the graph-based method to identify the best candidates, then do the detailed RBD calculation for that candidate only.
Proceedings of the 2018 3rd Joint International Information Technology，Mechanical and Electronic Engineering Conference (JIMEC 2018) (Atlantis Press) 2018
Offer 'UPS + utility (mains) dual bus' as a topology template beside 2N and N+1, with an RBD calculation that shows it can match 2N for dual-corded IT load.
World Electric Vehicle Journal (MDPI AG) 2023
Plan UPS battery replacement from the RUL of the weakest cell rather than the string average; in a series string one cell sets the replacement date for the whole string even when others have years of life left.
Uptime Institute Intelligence 2023
DLC design checks: CDU redundancy, TCS loop isolation and ride-through for pumps.
Eaton 2008
In the coordination checker store device type (fuse class, breaker with or without instantaneous, STD band) and use ratio tables or tested pair tables rather than curves when fault current puts both devices below 0.01 s.
Socomec 2010
Give the STS catalogue fields for rated current (A), IEC 62310 class code (CB/PC, neutral NC/NS/NI, BB/MM, S and T grades) and backfeed protection.
Schneider Electric 2017
Build the data model on the facility > room > pod > cabinet > device hierarchy and give each subsystem a deployment level and a linkage rule (for example 1 CRAH per N racks).
Nortek Air Solutions 2020
For sites in hurricane or tornado regions, require a wind-pressure rating (psf at design pressure) for outdoor mechanical equipment and derive the required psf from wind speed, risk category and mounting height.
Schneider Electric 2015
Let users define a reusable power/cooling/rack module and replicate it across phases and sites, with BOM and labelling generated consistently.
Revista de Informática Teórica e Aplicada (Universidade Federal do Rio Grande do Sul) 2019
Recognise that topology choice is only part of availability; equipment selection within a fixed topology can trade availability, losses and cost.
Uptime Institute Journal 2026
Use these ratios as indicative risk multipliers in an option-comparison view, for example showing relative outage likelihood when switching cooling from N+1 to 2N.
ABB 2008
Model each protective device with Icu, Icw, I1/I2/I3 settings and t2 curve type so the tool can evaluate selectivity pairs.
Teksan 2025
Add DCP to the rating-class field of the generator catalogue and set 'utility parallel allowed' to false for it.
Vertiv 2023
For edge and closet designs, default the single-phase UPS battery to Li-ion where room temperature is uncontrolled, and show replacement cycles in lifecycle cost (VRLA 3-5 y, Li-ion 8-10 y).
Data Center Frontier (Black & Veatch contributed article) 2024
Offer a substation object with a configuration field (radial, main-tie-main, ring bus, breaker-and-a-half, double-bus double-breaker) and an insulation type field (AIS, GIS), with footprint and cost multipliers.
ABB 2014
Give the UPS catalog an architecture field {monolithic, CPA modular, DPA modular}, module kW, modules per frame, maximum frames in parallel and per-module static bypass (yes/no).
Data Center Knowledge 2014
Add maintainability checks: service clearances on the access side of each unit.
Upsite Technologies blog 2025
Expose server ASHRAE class as a project-level design input that drives economizer hours, chiller sizing and redundancy credit.
Schneider Electric 2011
Encode the seven IEEE 1159 categories as a list used in risk registers and mitigation pickers.
Schneider Electric 2016
When the user raises the inlet setpoint, include server fan power and airflow increase (flat/low/moderate/high CFM-vs-inlet curve) and CRAH fan and count changes; warn when PUE improves but total energy rises.
Energies (MDPI AG) 2017
For paralleled modules in a modular UPS, do not look only at the N+1 redundancy count; add to the design check that module-to-module filter and control parameter differences cause circulating current and thermal imbalance.
