Lombardini22 designed the mechanical and electrical structures of the first LEED Platinum building in Italy.

Maximizing energy efficiency means minimizing management costs but also reducing waste by building sustainable.

This is a mission and a goal that Lombardini22 reached designing air conditioning systems serving the 11,000 square meters of office space in the first building of the Energy Park.

The plant is a mixed primary air and fan coil. The primary air distribution flows through the 4 shafts created at the two stairwells, the secondary distribution passes in the false ceiling instead, along the primary circulation route of the offices. The units consist of fan coil terminals connected to high induction diffusers on the ceiling, the primary air is fed into the distribution network of fan coils and before entering the environment.

The production of fluids is entrusted to two multipurpose hybrid condensing units. The control system, depending on climatic conditions and building requirements, decides the priority of one of the two units, one air cooled and the other water-cooled. The water condensation circuit consists of water taken and released from separate wells. The circuit is disconnected from the condensation circuit of the multipurpose units by means of a plate heat exchanger.

The key benefit of multi-purpose units is derived from the full exploitation of concurrent requests recovery of heat and cold from the building. That possibility should substantially increase the excellent performance of the unit, to the benefit of energy efficiency of space.
