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.
Consulting-Specifying Engineer 2017
If containment roofs or chimneys are placed, require sprinkler heads below or inside the containment, or fusible-link drop-away panels.
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.
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.
World Meteorological Organization 2012
Use the stated Celsius convention and applicability range when comparing dry-bulb, dew point and relative humidity.
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 2026
Evaluate cooling and siting options on energy, carbon, site water and water scarcity together, not on PUE or WUE alone.
ABB 2015
In the layout engine default front working clearance to 1.2 m for MV switchgear and 0.9-1.0 m for LV, with a jurisdiction override (e.g. NEC 110.26/110.34).
Meta 2026
Add a fuel-type parameter to the generator catalog {diesel, HVO, natural gas, dual-fuel}, with HVO as a drop-in option for the same genset.
ABB 2026
For loads above roughly 30-50 MW add a grid-code compliance checklist (LVRT duration, frequency band, RoCoF, PF) and let users choose LV-UPS versus MV-UPS architecture.
NFPA 2024
Defaults for white space in NFPA jurisdictions: 1-hour rated walls, 3/4-hour doors and rated fire/smoke dampers at penetrations.
NFPA 2024
When the user selects VEWFD, auto-place aspirating sampling ports at no more than 200 ft2 (18.6 m2) each and check from pipe length that transport time is under 60 s.
Open Compute Project Foundation 2026
Base floor and transport-route load checks on the 8,000 lb rack and the 15,000 lb rack-plus-sidecar combination, and include the weight of the moving equipment.
Schneider Electric 2020
In the edge template, allow a ventilated enclosure when IT load is 4 kW or less.
Schneider Electric 2026
Offer a 'prefabricated IT pod' option in the white-space designer, with catalog defaults 1.2 MW, 42 racks, 93 m2.
Eaton / Trane 2025
Voltage-selection rule: motors above about 200 kW (large chillers and pumps) default to MV (4.16/6.6/11 kV) feeders; compute I = P/(sqrt(3) x V x PF) to show cable savings.
Schneider Electric 2024
Add SMR to the site-selection module as an onsite-generation option, as a long-lead (2030+) placeholder
Schneider Electric 2026
Add a construction-method option for electrical rooms: stick-built or prefabricated module.
Schneider Electric 2023
Offer 'traditional' versus 'prefabricated modular' build strategy as a design option.
Cabling Installation & Maintenance 2024
Add an 'edge / micro-edge' project type with a Type A/Type B resilience choice; Type A can justify lower site redundancy because workload fails over
Siemens 2013
Use the tier factors as defaults in the early-stage area estimator: grey space = white space x factor.
U.S. DoD (UFC) 2019
Settle the loop or alternate-feed arrangement and the maintenance isolation points for the MV run from utility entry to the building early; the text treats shortening maintenance outages as a direct design driver.
