BICSI Data Center Design Consultant (DCDC) certification

Add a 'credentials' field to the user profile and recognise DCDC as a value there.

• ANSI/BICSI 002-2024 is listed as a related resource.

Bilgi ve İletişim Güvenliği Rehberi - 3.6.2 Sistem Odası/Veri Merkezine Yönelik Güvenlik Tedbirleri (Information and Communication Security Guide - measures for system rooms/data centres)

Provide a Turkey public-sector compliance checklist mapping the measures to design objects: dedicated IT UPS, N+1 air conditioning with auto changeover, redundant feeds, generator fuel redundancy, room adjacency checks against wet areas.

• Water, power, humidity, temperature and smoke must be monitored with thresholds and alarms; monitoring must not be exposed externally (3.6.2.5).

Regulation on the Fire Protection of Buildings (Binaların Yangından Korunması Hakkında Yönetmelik)

In the TR profile, default IT-room suppression to a TS ISO 14520 clean-agent design with damper-close interlocks.

• Accredited oxygen-reduction systems may be used in normally unoccupied enclosed spaces such as IT system rooms (Article 98(6)).

Carbon Explorer: A Holistic Framework for Designing Carbon Aware Datacenters

Add an hourly 24/7 CFE coverage calculator to site and energy design that sizes wind, solar, BESS (in hours of IT load) and server headroom together; use hourly or sub-hourly supply profiles, never daily averages.

• Grid lifecycle intensities (gCO2eq/kWh): wind 11, nuclear 12, hydro 24, solar 41, biofuels/other 230, natural gas 490, oil 650, coal 820.

Charting the Financial Roadmap and Economics of BESS Adoption for Data Centers

Add a BESS block to the site model with power (MW), duration (h), reserved-backup fraction and grid/island capability.

• 10 MW / 4 h BESS capex estimate $14-21 M (battery, inverters, enclosure $12-16 M).

Schneider Electric · 2014

Choosing the Optimal Data Center Power Density

Capture peak kW/rack and the peak-to-average ratio as well as the average, and express density in W/rack instead of W/m2.

• IT devices typically draw under 50% of nameplate power-supply rating.

Commissioning on-site electrical systems

For phased builds, the tool should place load-bank connection points and isolation breakers and output a Cx test list with individual, discrete and integrated levels.

• The owner estimated a $5 million recovery cost had the load dropped.

Schneider Electric · 2021

Comparing IEC 61850 vs. Traditional Monitoring, Protection and Control Solutions in Large Data Centers

Add a protectionControlScheme attribute to the MV module: hardwired_plc_modbus, iec61850_station_bus, iec61850_process_bus.

• GOOSE: under 4 or 10 ms, self-monitored multicast.

Schneider Electric · 2011

Comparison of Static and Rotary UPS

Store UPS efficiency as a curve with at least 25/50/75/100% load points, plus storage type (battery, flywheel) and ride-through seconds.

• Rotary can cost 40% more up front and is typically not modular.

Condition-Based Maintenance Services Address Data Center Challenges

Record telemetry capability (protocols, factory sensors, remote monitoring support) in the equipment catalog.

Cummins · 2017

Considerations when Paralleling Generating Sets

Check smallest-to-largest set ratio against the 30% guideline and flag designs below it.

• Waveform guidance: THD up to 5%, any single harmonic up to 3%.

Schneider Electric · 2017

Cost, Speed, and Reliability Tradeoffs between N+1 UPS Configurations

Distinguish 'N+1 internal modular', 'N+1 parallel redundant' and 'isolated redundant' instead of a single N+1 flag; for modular frames store module rating, max modules, shared battery bus and redundant controls/fans.

• Internal N+1 is $178/kW (26.9%) cheaper than parallel.

Eaton · 2025

Data Center as a Good Grid Citizen

Add grid-code parameters to the utility connection object: UFLS stages, LVRT curve, post-fault power recovery ramp (%/s) and short-circuit ratio at the PCC.

• Typical BESS Li-ion cells are limited to about 1C discharge.

Consulting-Specifying Engineer · 2018

Data center co-location electrical system design

In business-model templates (enterprise, colo, cloud), set default redundancy and base-to-redundant ratios.

• N example: a 1,800 kW load with 1,000 kW UPS modules gives N = 2.

Cummins · 2025

Data Center Continuous (DCC) Ratings: A comparison of DCC ratings, ISO definitions and Uptime requirements

Give generator catalogue entries a rating table keyed by class {ESP, PRP, COP, DCP, DCC/manufacturer-unlimited} rather than a single kW value.

• QSK95-based sets offer ratings up to 3.5 MW (ISO 8528-1).

Cushman & Wakefield · 2026

Data Center Development Cost Guide 2026 (U.S.)

In the cost module, offer an all-in $/MW benchmark band with source and year and allow a market multiplier.

• Development costs up 21% per MW since the previous report.

Data Center Electrical Power Chain Tool, v2.5 (July 2023)

Benchmark the electrical loss model against this tool's structure: transformer, UPS and PDU efficiency curves by load factor, plus eco-mode.

• The July 2023 update added transmission and distribution (T&D) losses.

Data Center Evolution: Powering the AI Revolution Sustainably (OCP EMEA Summit 2025 keynote, Madhusudan Iyengar)

Rack catalogue entries should carry a distribution-voltage attribute (48 VDC, +/-400 VDC, AC); flag 48 V in-rack designs above roughly 150 kW per rack as needing a sidecar or higher-voltage DC architecture.
