Cummins 2025
Sum fault current at the collector bus from catalog X"d, kW, V and pf, add motor and transformer terms, and check breaker kAIC and bus bracing.
Electronics (MDPI AG) 2018
When selecting double-conversion UPS, include the measured efficiency curve by load point and the annual energy cost of the loss difference (here about 1380 USD per year for 450 W) in total cost of ownership.
ASME (Digital Infrastructure column) 2026
Default CDUs to N+1 per row or pod.
Consulting-Specifying Engineer 2018
Support both distributed-redundant and catcher/reserve UPS topologies with automatic post-failure load checks, warning if any unit exceeds 100% after a single failure.
Vertiv 2022
In a retrofit workflow identify zones above about 30 kW/rack and propose rear-door heat exchanger or direct liquid cooling options.
European Commission JRC 2019
Seed the embodied-versus-operational carbon module with the roughly one third procured assets and two thirds use-stage split as a default sanity check for LCA outputs.
Cummins 2015
Compare candidate set sizes on count, footprint, install and maintenance cost for the target N+x, preferring fewer larger sets where the site allows.
Schneider Electric 2016
Store full UPS efficiency curves (10/25/50/75/100% load), ride-through, footprint and service clearance, and a technology field (static VRLA, static Li-ion, DRUPS) rather than one peak value.
Eaton 2017
Treat the UPS in inverter mode as a current-limited source in the short-circuit engine, with catalogue fields inverterIscMultiple, inverterIscDuration_ms, bypassIcw and maxProspectiveFaultAtBypass.
ABB 2008
For main switchboards with two transformers plus bus tie, or generator paralleling boards, flag that conventional time selectivity cannot discriminate fault direction and propose directional or directional-zone selectivity on incomers and bus tie.
European Parliament and Council of the European Union 2023
If the site's installed IT power is 500 kW or more, provide in the design for the annual Annex VII reporting and the monitoring infrastructure (energy, power utilisation, temperature set points, waste heat, water, renewables); measurement is based on the EN 50600-4 family.
Frontiers in Energy Research (Frontiers Media SA) 2022
For loads of 50 kW per rack and above, evaluate a hybrid cold-plate scheme (main loads on cold plates, remaining heat in air) for a PUE target below 1.2.
7x24 Exchange Magazine 2024
Compute and plot PUE versus IT load for phased designs, showing step changes when each POD or block is energized.
U.S. Department of Energy 2025
Track as a regulatory and site news item linked to the DOE RFI and EO 14318 records.
Lawrence Berkeley National Laboratory / U.S. Department of Energy 2022
Mirror this process in the audit workflow of the operations module: pre-visit data request, on-site measurements, report.
Lawrence Berkeley National Laboratory 2025
Add a demand-flexibility scenario to the energy model: curtailable IT share and on-site generation or BESS dispatch.
U.S. Department of Energy / Federal Register 2025
For federal-site scenarios, keep water (million gal/day), grid market (MISO, PJM) and area (acres) as separate fields in site records.
U.S. Department of Energy / Federal Register 2025
When planning a large load connection, query the interconnection queue, transmission congestion and reconductoring potential for the relevant grid region early.
Cundall 2021
Allow server fan power to be entered as a fraction of IT load and compute TUE alongside PUE.
Uptime Institute Journal (Uptime Institute) 2021
When comparing air and DLC options, report total facility energy and IT energy, not PUE alone.
Open Compute Project Foundation 2025
Record approach temperature difference, P-Q curve, fan/pump redundancy and coil material in rear-door and sidecar catalogue items.
Consulting-Specifying Engineer 2015
Include economizer control limits, part-load loss curves for each electrical stage and the redundancy topology as energy model inputs.
Jacobs 2023
Use the 6.75 Mgal/MW-yr figure as a sanity-check benchmark for evaporative designs.
Uptime Institute Journal 2014
In Tier III/IV templates, route two independent active paths from UPS output to each rack.
