Equinix 2022
Default the cooling module's supply-air setpoint for colo profiles to 27 degC (upper end of the ASHRAE recommended 18-27 degC), with a sensitivity chart of PUE and economizer hours versus setpoint (e.g. 22 to 27 degC).
Uptime Institute Journal 2021
Do not display legacy availability percentages such as 99.671/99.741/99.982/99.995 as Tier properties
FEMA 2007
For site selection, look beyond the 100-year flood to the 500-year (0.2%) flood and the facility's occupancy category, and avoid flood hazard areas where possible.
FEMA 2014
At critical-facility data centers, place generators, ATS, fuel tanks and pumps above the greatest of BFE + 3 ft, DFE + 1 ft and 500-year elevation + 1 ft, and prefer elevation to dry floodproofing.
Siemens (with Jensen Hughes) 2025
Structure the fire module by room type: white space, UPS/battery room, lithium-ion BESS, generator, electrical rooms.
Schneider Electric 2019
Use 20 kW per rack (the Green Grid midpoint) as the default threshold at which the wizard recommends evaluating liquid cooling.
ASHRAE TC 9.9 2009
If an air-side economiser meets an urban or industrial site, prompt for corrosion coupon monitoring (G1 target) and MERV 11/13 makeup-air filtration.
NOAA National Centers for Environmental Information (NCEI) 2016
For cooling design use a station's hourly dry-bulb and wet-bulb (or dew point) data to count free-cooling and economiser hours in 1 degree C bins; SoSo CAD builds annual 1 degree C dry-bulb and wet-bulb hour bins for this purpose from one year of station files.
Google 2026
In the efficiency dashboard show three PUE references: design PUE, partial-load PUE (at 25/50/75% IT load) and benchmarks (Google 1.09 hyperscale; Uptime 1.54 industry).
Google 2026
In the cooling-selection UX present an explicit energy-versus-water trade-off (PUE versus WUE) per site, with a water-stress input (for example a WRI Aqueduct category).
U.S. General Services Administration (Public Buildings Service) 2020
Set up the commissioning plan at the start of a data center project: review the OPR and basis of design with the CxP and write measurable performance targets.
Schneider Electric 2015
Build the PUE calculator on an explicit load-classification table: each catalog component is IT, infrastructure, excluded or shared.
World Meteorological Organization 2012
Use the stated Celsius convention and applicability range when comparing dry-bulb, dew point and relative humidity.
Schneider Electric 2014
Make the primary density inputs per rack: avgRackKw and peakRackKw per row or zone, default peak/avg 2
Schneider Electric 2015
Build a novice criticality wizard (C1-C4) and map defaults to it: fuel autonomy 0/24/72/96 h, utility feeds 1/1/2/2, fire rating 0/0/1/2 h.
Open Compute Project Foundation Year not stated
Write the PG25 or PG55 choice into the fluid specification according to the freeze protection the climate needs, and record that keeping glycol above 25% by volume removes the need for biocide.
Open Compute Project Foundation 2023
Write the Table 1 targets (TSS, TDS, conductivity, copper and iron, pH, hardness, turbidity, bacteria, azole inhibitor, chloride) into the fluid specification as acceptance criteria and request a certificate of analysis from the supplier.
Open Compute Project Foundation 2026
Evaluate cooling and siting options on energy, carbon, site water and water scarcity together, not on PUE or WUE alone.
The Green Grid (Global Metrics Harmonization Task Force) 2014
Present PUE, partial PUE, REF/GEC, ERF, WUE and CUE as one consistent metric set in every report.
Schneider Electric 2017
Add the indirect evaporative cooler (IEC) as a plant type, with parameters for approach temperature, wet-bulb effectiveness, trim DX capacity fraction and water use only during evaporative hours.
Vertiv 2022
Add to the UPS catalog an efficiency curve per mode (VFI/VI/VFD) at 25/50/75/100% load and a transferTimeMs per mode.
Schneider Electric 2026
Add an AI cluster design profile with rack defaults of 750x1,200 mm, 48U, static 2,270 kg and dynamic 1,600 kg.
Schneider Electric 2021
Expose CHW supply temperature (default 15 C for new builds, range 7 to 21 C) and CHW deltaT as design inputs, and recompute economizer hours, chiller kW and CRAH coil selection when they change.
Schneider Electric 2024
Build an rPDU selector: from rack kW, voltage, phases and redundancy, compute PDU count with an 80% (NA) or 100% (IEC) factor.
