IEEE Open Journal of Power Electronics (Institute of Electrical and Electronics Engineers (IEEE)) 2026
In rack power templates, model PSU count per shelf and the 33 kW shelf limit for AC distribution, and check busbar, PDU and cooling impact together for racks that exceed 100 kW with several shelves.
Revista de Informática Teórica e Aplicada (Universidade Federal do Rio Grande do Sul) 2019
Recognise that topology choice is only part of availability; equipment selection within a fixed topology can trade availability, losses and cost.
Sustainability (MDPI AG) 2021
Calculate UPS load ratio (80% for 800 kW in a modular arrangement, 53% in parallel-redundant) and losses at design stage; consider specifying UPS efficiency at 30% load and compare a SiC-based power stage (above 98%).
Sustainability (MDPI AG) 2026
Do not size behind-the-meter battery storage on an emission-reduction case; round-trip losses mean storage alone adds nothing and can raise emissions. Justify it with a concrete duty such as masking checkpoint dips.
Proceedings of the 2023 ACM Symposium on Cloud Computing (ACM) 2023
Consider a GPU power cap (for example 60% of peak) as a control in capacity and cooling planning: about 10 W per job and a 4.78 °C lower mean temperature were reported.
European Commission, DG CNECT (EY, Borderstep Institute, AIT, RP legalitax) 2025
When choosing cooling architecture assess waste heat temperature early: liquid cooling gives higher temperatures, even air cooling can give about 30-35 C as a heat-pump source; position the heat pump for the receiving network temperature (60-80 C or 4th/5th generation).
Open Compute Project Foundation 2025
In heat-reuse modelling, allow an adsorption-chiller sink with a minimum drive temperature (around 65 C).
Mitigation and Adaptation Strategies for Global Change (Springer Science and Business Media LLC) 2022
When combining data-centre cooling and heat recovery for district heating in one heat-pump system, select the refrigerant among low-GWP alternatives with COP, PUE, ERF and payback together.
Energies (MDPI AG) 2021
Evaluate an absorption chiller driven by roughly 70 °C water from liquid-cooled racks to cut compression chiller load; calculate the hybrid saving from the two COPs with the closed-form formula.
Energies (MDPI AG) 2026
Evaluate magnetic-bearing chiller investment by climate: payback was 5.8 years in a hot climate relying more on mechanical cooling, 36.6 years in a cold climate dominated by free cooling.
Türkiye Elektrik Dağıtım A.Ş. (TEDAŞ) 2017
In the transformer catalogue (TR profile), preload hermetic transformer loss data (P0, Pk) by kVA from this specification as defaults.
Swiss Federal Office of Energy SFOE (Energy Research and Cleantech); preprint on arXiv 2025
Add an IT-side penalty of about 0.3-0.6% of IT power per C of inlet rise above about 23 C (a configurable default) to the setpoint optimiser and energy calculator, and model fan power with the cube of speed.
Patterns (Elsevier BV) 2025
Use location-specific grid water-intensity factors (L/kWh), not a national average, when calculating indirect water.
Sustainability (MDPI AG) 2023
Treat an airside economiser as a strong option in moderate climates (Stockholm 86%, San Francisco 76%); in Dubai and Singapore energy can rise (+2% and +4%).
arXiv preprint 2026
For EU projects, add an EED compliance module that flags facilities of 500 kW and above as reportable.
Upsite Technologies blog 2025
Expose server ASHRAE class as a project-level design input that drives economizer hours, chiller sizing and redundancy credit.
Schneider Electric 2016
When the user raises the inlet setpoint, include server fan power and airflow increase (flat/low/moderate/high CFM-vs-inlet curve) and CRAH fan and count changes; warn when PUE improves but total energy rises.
arXiv preprint (University of Alberta) 2024
Define AI load not only by energy but by peak/average (about 1 in training), peak/idle ratio and ramp/decline rates; make sub-second dynamics inputs for UPS, generator and grid-connection studies.
Energies (MDPI AG) 2023
In preliminary cooling selection, make climate (humidity, haze/dust) and the free-cooling switchover point decisive inputs; direct airside economisers may be unsuitable in haze- and dust-prone regions.
Energies (MDPI AG) 2025
When evaluating turning liquid-cooled data-centre waste heat into electricity, weigh RTE (76-83%) against specific cost (767-1125 USD/kWh); higher RTE can come with a cost increase.
arXiv preprint (University of Alberta) 2026
In large-load interconnection negotiation, present AI load flexibility (a deferral window of up to about 3 hours) as a lever for interconnection capacity and timing; returns diminish beyond 3 hours.
Huawei Digital Power 2024
For lithium BESS/UPS rooms, require detection and segregation sized for a 30-60 s runaway escalation.
U.S. Environmental Protection Agency (ENERGY STAR) 2023
Make a blanking-panel and gap-filler check a required step in colocation cage and rack layouts, and flag unused rack units.
Siemens 2018
Offer W/m2 defaults by building type (data centre vs IT room) and redundancy-dependent simultaneity factors in early sizing.
