Background

Cà Litta is a historic building located in the centre of Milan, characterised by a remarkable architectural and cultural value. Cefla's work aimed to modernise the technological systems, improving energy efficiency and comfort without altering the historical integrity of the building.

The building, which has seven floors above ground and three basement floors, features spacious executive offices and meeting rooms.

Challenges

  • Integration into a historical setting
    Implementing advanced technological solutions while being respectful of the architectural and historical characteristics of the building.
  • Structural limitations
    Working in confined and restricted spaces, adapting the plant engineering solutions to the specific characteristics of the existing building.
  • Tight deadlines
    Completing the work within a limited time frame, minimising the impact on the building's activities.

Project Tasks

Cefla has carried out:

  • Replacement and upgrading of thermo-mechanical systems, improving energy efficiency and environmental comfort.
  • Implementation of a Building Management System (BMS) for centralised control and monitoring of the systems.
  • Installation of electrical and special systems, including safety and lighting systems, in compliance with current regulations.

Implementation

Completed in 2019, the project was delivered on schedule and ensured business continuity. Cefla's integrated approach effectively coordinated the various phases of the project, ensuring high standards of quality and performance.

CLIMATE CONTROL

On the roof of the offices, 12 external units of 45 kW and one of 56 kW power the internal units, providing heating and cooling. Two rooftop units treat 20,000 m³/h of outside air. In the lobby, floor panels support the internal units in winter. Via Pantano side (residential units): Floor panels air-condition the residential units, with towel warmers in the bathrooms. They also operate in summer with water at 18°C to prevent condensation and cool the air. A 7,000 m³/h rooftop unit and fan units with heat exchangers manage air exchange and humidity. The water for the panels and towel warmers is produced by a multi-purpose unit and distributed by pumps in an underground plant.

DOMESTIC HOT WATER PRODUCTION

Porta Romana side (Unipol offices): A direct expansion machine produces domestic hot water at 50°C. Via Pantano side (residential units): The multi-purpose unit produces domestic hot water at 50°C.

SMOKE DETECTION SYSTEM

The SIEMENS system, managed by two control units, monitors 500 detectors and 24 air analysis modules.

BMS SYSTEM

Two BMS systems manage the building, one for the offices and the other for the common areas of the residential units.

PHOTOVOLTAIC

Photovoltaic panels on the office roof produce almost 10KW.

FIRE PREVENTION

The access ramp and underground car parks are protected by a sprinkler system, with UNI45 fire extinguishers and hydrants throughout the building.
