Compute more, waste less

Fully transparent data center efficiency and environmental footprint

We are transparent about data center efficiency

We are proud to lead the way in recognizing the impact we can play in mitigating climate change by questioning the techniques used to run data centers. Rather than planting trees, we prefer to think outside of the box and innovate where it counts most, at the source.

We leave nothing to chance

Everything was clearly conceptualized and meticulously built down to the last detail to achieve a holistic approach and create exceptionally energy and water efficient data centers.

We are incredibly honest with you

We’ve built real-time dashboards (below) to show our data center efficiency and conditions, iPUE (Real-time Power Usage Effectiveness), PUE (Power Usage Effectiveness) and WUE (Water Usage Effectiveness). Because we’ve always challenged the status quo, we will inform our customers about the environmental impact (energy consumption and estimated carbon emissions) of the products they use at Scaleway. A first in the industry!

Real-time data center iPUE

We work hard to maintain extremely efficient data centers, and we use data including PUE to track the performance of our facilities.

DC2 

fr-par-1 – Paris, France

DC2 Datacenter uses only dry cooling systems and closed chilled water circuits, our WUE (Water Usage Effectiveness) is 0.

With its highly efficient chilled water cooling and UPS system, DC reaches a maximum PUE of 1.5.

DC3

fr-par-1 – Paris, France 

DC3 Datacenter uses indirect free cooling with a closed-loop high-temperature chilled water system. Our WUE (Water Usage Effectiveness) is 0 as we do not use any water evaporation in our cooling process.

Dry-coolers are also used for the indirect free cooling system (free-chilling), through high efficiency water heat exchangers between these dry-coolers and IT chilled water.

The holy grail of data centers, DC5

Eco-AZ fr-par-2 – Paris, France

DC5 Datacenter was designed as a hyper-scaling data center. It features a high-density design by default, combined with the lowest PUE in Europe at 1.15.

This highly innovative data center uses a direct free cooling system with adiabatic cooling to cool down data halls. Other rooms (MMR, Telco rooms, UPS rooms, etc.) use direct free cooling combined with an ice storage system.

We are transparent about how we calculate your environmental footprint

At Scaleway, PUE is not just a marketing term. PUE is PUE, other ways to calculate efficiency should not be called PUE. Contrary to market practices, our PUE is calculated using the International standard ISO/IEC 30134-2:2016, backed by our ISO 50001:2018 certification.

Measurements are taken every five minutes by certified Class 1 or Class 0.2C true-RMS meters as defined by Directive 2004/22/CE (Measuring Instruments Directive). 

As defined by ISO/IEC 30134-2:2016:

  • Our PUE is a category 1 PUE and calculated with the last 12 months’ measurements
  • Total Energy power consumption (E-DC) is calculated on medium voltage from the national grid
  • IT Load (E-IT) is calculated on UPS output
  • Energy consumed by the non-data center equipment (such as offices) is excluded 
  • Real-time values are calculated by the last five minutes’ average measurements and must be considered as i-PUE for information purposes

The environmental footprint of the products* that you use at Scaleway is calculated with the following formula:

Consumption (average) in kW of the product * PUE of the data center * Energy MIX of the data center * Number of hours consumed by clients.
