Eaton 2018
Add backfeedProtection (internal or external), Icw/Icc rating and required SCPD to the UPS catalogue.
Uptime Institute 2022
When selecting a UPS topology, cite UPS failure as the leading power-incident cause and offer a maintenance bypass and redundant modules as defaults.
Uptime Institute 2021
When building a failure-mode catalogue, list the UPS, ATS/STS and generator as the main power-outage contributors.
Energies (MDPI AG) 2022
When considering VRLA UPS strings for grid services, account for frequency regulation (especially in a low SOC window) degrading batteries much faster than peak shaving, with capacity loss tracking internal resistance rise.
Energies (MDPI AG) 2018
Calculate battery room ventilation from hydrogen emission per BS EN 62485 (here 42.3 m³/h or 0.12 m² for a 20 m³ room) and separately show the time to reach LEL if ventilation fails.
Vertiv 2024
Extend the power-source library beyond utility plus diesel: BESS (AC- or DC-coupled to the UPS), SOFC prime power, PEM backup fuel cell, PV and CHP, each with fuel type, start time, ramp capability and emissions factor.
The Green Grid 2007
In the electrical topology library, tag topology templates (480/208 V AC, 415/240 V AC, DC options) with qualitative pros and cons.
The Green Grid 2012
In the UPS module, model double-conversion and Eco/ESS modes with separate efficiency curves.
The Green Grid 2012
In phased-build planning, support staged UPS and generator modules with efficiency at each load step.
The Green Grid 2015
Offer a reduced-conversion topology scenario.
The Green Grid 2016
Store PSU ride-through (ms) as a catalog field for IT equipment.
Eaton 2021
In the asset/lifecycle module store the installation year per UPS and battery, and project replacement dates from the component table defaults.
TMMOB Makina Mühendisleri Odası (MMO) 2007
Warn when IT and comfort loads share one UPS or one chilled-water primary loop, since that blocks independent temperature reset and free cooling.
Schneider Electric 2021
In the operations module attach a maintenance strategy and default PM interval (quarterly/semi-annual/annual) to each catalog asset class, with a condition-based monitoring option.
Schneider Electric 2018
Add battery catalogue parameters: chemistry, service life at 25°C, m² per kWh, kg per kWh and floor loading.
Schneider Electric 2017
Prefer Li-ion with a 10-year life as the default for edge and rack UPS.
Eaton 2016
Add a designLifeYears catalog parameter per equipment type, default to the range midpoint, and drive a TCO/refresh timeline from it.
Schneider Electric 2011
Use it as a quick-sizing calculator in novice mode: take IT kW, future kW, floor area, cooling type and UPS input type, and output service kW/A and generator kW, with the multipliers as editable defaults.
Schneider Electric 2016
Offer N, isolated redundant, N+1, distributed redundant (catcher/STS), tri-redundant, 2N and 2(N+1) in the topology library, and label availability values as comparative rather than absolute.
Schneider Electric 2022
In the single-line builder, raise a warning when the transfer switch has 4 poles and the UPS neutral is not separately derived.
Schneider Electric 2020
Use C-rate-dependent usable energy (Peukert-like) in the battery runtime calculator rather than nameplate kWh.
Open Compute Project Foundation 2026
For a new site, write the POI LVRT/HVRT envelope and the PFAPR requirement (90% within 2 s) as design criteria, and settle which voltage measurement (line-to-neutral or line-to-line) governs during protection coordination with the utility.
ASHRAE TC 9.9 2016
Encode the A1-A4 table (dry bulb, dew point, altitude derate) as the canonical envelope lookup; site max inlet = classMax - (altitude-900)/derateStep.
Open Compute Project Foundation 2026
Check that the facility's AC feed (480, 415 or 400 V, single or dual) and the rack power range match the planned IT block, including up to 1.1 MW per sidecar and the parallel option.
