Teads, Workflowers and Hardbricks collaborate on measurements for cloud infrastructures

Teads, Workflowers and Hardbricks have partnered to measure the power consumption of Amazon AWS instances. It’s still an early step in the process of measuring the carbon emissions of cloud infrastructure but it sets the base for open discussions and calls for more transparency from cloud services providers.

The results of this experiment will be presented by Benjamin Davy and Cedric Lejeune at next Network Technology Seminar Event at EBU

Contribution to Green Games Guide

UKIE trust and Games London in partnership with UN’s initiative Playing for the Planet released the Green Games Guide, a milestone document to show the environmental impact of the video games industry. Benoît Ruiz of Workflowers is the co-author (with Daniel Wood from UKIE), he contributed to the scientific data and innovations that could help the video gaming sector in its challenges with climate and resources. Check it out!


You’re cool, but are you R 32 or R 410 A cool?

Behind these mysterious codes lie the viability of your cooling system for the next 10 years.

With global warming and the need for exponential calculations due to 4K today and 8k tomorrow a cooling system is increasingly essential to ensure the operation of your on prem data infrastructure; it maintain the set temperature.

Fluorinated greenhouse gases (F-gases), including hydrofluorocarbons (HFCs) like refrigerants R410A are use by cooling system for thermal exchange. These HFCs replaced Ozone Depleting substances (ODS) that damaged the stratospherice ozone layer. The Montreal Protocol (1987) phases down the CFC’ production and consumption.

 However HFCs, used as a substitute, have proven to be aggravating factors of global warming and could represent 20% of global greenhouse gas emissions in 2050.  That’s why the new European regulation F-Gaz II organizes the rarefaction of HFCs on the market according to their Global Warming Power (GWP).

GWP by refrigerant – source: F-gas II

The refrigerants GWP e.g. R410A = 2 O88 are compared to the CO2 one = GWP 1.

Gradually refrigerants are withdrawn from the market depending their GWP thresholds :

  • 2025 : ≤ 1000
  • 2030 : ≤ 400
Refrigerants removal date – source F-gas II

How it will impact your cooling system?

Nowadays most of the air-cooling system use R 410 A, in 2025 you will have to switch to R32, it means costly renovation: the compressor and the condensator must be replaced.

Cooling system has an average 9 years lifespan, so it is time to be wise in your investment and choose a cooling system running on R 32 that will last till 2030.

Until then, you can decide to rationalize your needs and adopt free cooling solutions, Workflowers can facilitate you, this low cost & low carbon transition.
