The maximum of customization for the new Six Senses Rome


Six Senses Rome will be inaugurated in 2022. The hotel will be located in the Salviati Cesi Mellini Palace in Piazza di San Marcello, in the heart of the Eternal City. Highlights include 95 distinct rooms and suites, a spa, restaurant, event terrace, outdoor garden courtyard, and rooftop terrace with 360-degree views of the city and monuments.


The main challenge required by the Ariatta Engineering – in charge of designing the electrical, mechanical and special systems in accordance with the restrictions deriving from the installation site – was to overcome various constraints deriving from the type of site itself, from the installation space available from the property in accordance with the architectural impact of detail and context. We are in the historic center of Rome, a building bound by the superintendency and historical and architectural heritage of the capital.

Noise and performance were the first two obstacles. The request was to be able to build units that could respect the acoustic limitations of the site while guaranteeing a very high standard of energy efficiency. Dimensions, another very difficult step. Not only was it asked to create lowered multipurpose units due to the strict constraints of the space intended for the technical area, but at the same time a further difficulty coefficient was introduced: weight. The units were intended to be installed in the farthest point reachable by the crane on site, so it was imperative not to exceed the maximum permissible load otherwise it would have been impossible to install them on the roof.

Our advice

The continuous exchange of information with the partners involved in the project has made it possible to create an installation that could be defined as unique of its kind. Multipurpose units, made on the basis of a special color chosen to match the context in which they are installed, hypersilenced, with very high energy efficiency and… demountable.

The units have been built and completed in the Gubbio (PG) plant, have been tested and have been disassembled each in two separate blocks, allowing then the pulling on the roof in compliance with the loads allowed by the construction crane. Once pulled on the roof, the units were reassembled by carrying out the delicate connections of the refrigeration connections (gas pipes) of the water lines and of the electrical connections. A pressure test was performed again on the roof once the three units were installed and pending the progress of the construction site which will end with the start-up of the system.

The project

The project involves the installation of 3 multi-circuit multipurpose units with scroll compressors, R410A refrigerant gas made in a lowered and super-silenced version and capable of delivering 400 kW (114 RT) refrigeration and heating units in the smallest possible size each for a total of thermal and refrigeration 1.2 MW (342 RT). The production of hot water, in addition to serving the batteries of the air handling units present and the fan coil circuit, is used to power 3 water/water boosters for the production of high temperature domestic hot water made with scroll compressors, R134a refrigerant gas, about 140 kW (40 RT) each, capable of covering a requirement of 420 kW (120 RT) of hot water at 65 °C (149 °F) for use by the sanitary system.


Pending the completion of the plant engineering works, we can believe that the various technical challenges described have been overcome since each element that made this realization special has been completely linked and allowed the correct laying and installation of the entire system in accordance with the technical and physical constraints that they had been imposed on us in the first phase of technical exchange by the various construction site players.
