Paris Data Center Not Too Noisy, After All (datacenterdynamics.com) 77
judgecorp writes: A Paris court has ruled that a suburban data center can continue to operate, reversing an earlier decision to close it down after protests from residents. The data center's owner, Interxion, cited noise impact studies form 2014 which showed the site was operating within authorized limits, and also within the levels it predicted in its planning application

The sad fact of this matter is this new DC makes more noise than what was present, a clear backward step. Regardless of the industry, the planners should be aiming for a higher standard from everyone. There's no reason why a DC needs to make any noise outside the building itself.
Silent HVAC? So basically a miracle then?
HVAC is a standard minor background noise for any modern urban setting. It is no noisier for a DC than it is any generic office building.

The amount of noise produced HVAC system is to tied to the amount of heat it needs to remove. Since a DC produces probably 10 times the heat as a average office building. It without a doubt produces much more noise, unless special care is taken to suppress the extra noise.
Re: (Score:2)
10 times the heat probably translates to only a few decibels of extra sound power, and less difference than that in sound pressure at the lot line, if they do it right.
Anyway, the complaints were about the noisy backup generators, not the HVAC.

In theory, they should. In practice: they aim for whatever minimal effort that still manage to passes at what they law requires.

Air conditionning.
A data center generates heat. Which needs to be extracted, which means that there's some heat exchange process that is external to the building.
And the datacenter constructor probably went for the cheapest possible that still pass the law instead of the best.
Also, a data center generates quite some noise indoor (fans and spinning disks of all the machines) and it

Better solution would be the reflect the sound up and away, which is how highway sound barriers work. They either reflect the sound back within the corridor, or they're installed on a slight angle that reflects the sound away. The same solution would probably help in this case. The other option of course would be to use geothermal taps to cool, of course people would likely also throw a NIMBY hissy fit. An example of that would be a waste to energy plant in a nearby city, it produced electricity, and w

The government data center that I worked in was linked up to a bunch of others which dumped the heat into local river. Worked well except there was a couple of days we had to shut down because a boat dropped its anchor on the discharge pipe into the river damaging it.
I always thought we should have at least used the heat from the data center to create hot water for the building before sending it away to the cooling plant. It would have cost almost nothing for the building to run. Just a little bit of elect

Montreuil has a lot a gentrification currently going on. So, even if there still quite a lot of poor people, and a huge Malian community, there is also more and more wealthy people there. And quite a lot of jobs too, with all the offices of BNP Paribas.
But, in fact, it's not really relevant here, Montreuil is where the court is, not the datacenter. The later is in La Courneuve. I know less well this city, but there it seems there is also quite a lot of gentrification and (new) jobs there.

Not always. Auto race tracks that have been operating for decades are told to enforce sound limits or shut down completely because some new development opened 5 years ago nearby.

Realistically, lots of people benefit from the airport, but considerably fewer have major noise problems. NIMBY is a reasonable response sometimes. Many people moved into the flight area before the local airport got lots more busy and opened another runway, and really didn't expect the noise they got.
