In Lombardy there are already over 70 structures operating, while investment plans reach $2.5 billion in five years. Cooling and ventilation pose impact acoustic problems. The new demand arises from technical characteristics of digital devices, especially those intended for artificial intelligence applications.

High-density servers require large cooling infrastructures: towers, air treatment units, and refrigerator machines must operate without interruption. Their operation can produce low-frequency rumbles and continuous aerodynamic noises, transforming acoustics management into a relevant component of design. When these structures arise near densely inhabited zones, the issue becomes more delicate.

According to available sources, increasing imbalances render progressively more important noise limitation capabilities. It's not just isolating buildings but intervening on apparatuses ensuring permanent ventilation and temperature control. This market enters Sts, a small enterprise born in Torino in the Seventies under initiative of Cellerino's father.

The current entrepreneur guides it since 2012. The company comes from HVAC system ventilation and conditioning air sector, indicated by Hvac acronym, and has then transformed into an innovative small and medium-sized business with patents, research activities, and university relationships. Change in demand was sudden.

Until last April this year, the society had never received requests related to data centers. From that moment, according to the entrepreneur, the Sts started working on projects worth $45 million euros. Source does not specify how many orders are already made nor what part of value will translate into revenue.

Comparison with dimensions of the company shows the potential width of passage. Sts closed 2025 with annual turnover of $2.5 million euros. Value of cited plans is several times higher than annual revenues, however two data points cannot be directly compared: lack of indications about contracts, execution time and activity quota which will actually be assigned to the company.

To sustain this perspective is a national market where Corriere della Sera described before strong investment cycle. Lombardy constitutes main quantitative reference: there are over 70 data centers operating in region and new investments planned until $22 billion euros within five years. Available sources do not provide any temporal or territorial distribution of these programs.

A law entered into force in June at Lombardy under Attilio Fontana's presidency accompanies phase when presence of imprints is already considerable and new investments may further expand it. Content available does not illustrate obligations introduced by normative neither specific dispositions regarding noise or structure location. An orientation different from New York State is adopted.

According to source report, democratic governor Kathy Hochul has forbidden one-year construction of large-scale hyperscale data center. Cases lombardo and statunitense signal need for governing rapid growth of these infrastructures. In European context, Italy is indicated as one of most dynamic markets.

Milan area is associated with Madrid while Frankfurt becomes known as pole that has already experienced significant expansion. Concentration of investments in big urban areas makes central non only energy capacity and technology but also compatibility with surrounding territory. Sts' view depends on conversion of projects into communes, works executed and annual turnover.

Uncertainty remains about scanning 22 million dollars of investments mentioned for Lombardy, new structures locations and concrete effects of regional law.
