NEW JUDICIAL POLE
Trento

Commissioned by: PROVINCIA AUTONOMA DI TRENTO

Architecture: prof. arch. Pierluigi Nicolin

Detail design for the new Judicial Pole of the city of Trento

The welcome message given by the wide accessibility and the grid-like, instead of hierarchical, relation between the different functional areas represents the peculiar nature of the project.

The installation of "sun chasing" photo-voltaic systems on the roof have been foresee.
The new system (pat. Elettropiemme n° IT03/00565: SincroSunSystem) allows to increase of about the 40% the annual power generation, compared to a traditional (fixed) photo-voltaic system, with just the 13% increase on the initial cost of installation.
The system is designed for a total 20kWp (peak kW) and can generate about 28.000kWh (1.400kWh every 1kWp).
With a 140.000,00€ investment (7.000,00€/kWp x 20kWp) and referring to the incentive rate in the Italian Decree n° 181 - 15/08/2005 (0,455€/kWh for 20 years plus 0,12€/kWh saved for not buying power) the pay-back period is about 9,5 years and, after 20 years, there will be a Net Present Value of about 160.000,00€
Furthermore, referring to the Environment Office, every 1.000kWh generated by a photo-voltaic system avoid 0,53tons of carbon dioxide and other minor polluting agents to be released in the atmosphere.
This system will so be able to avoid the release of 15tons of carbon dioxide and other minor polluting agents every year.

Polyvalent refrigerators will produce both the hot and cold fluids.
These machines allow to recover the heat/cold discarded during the production of cold/hot water. Only the exceeding is released in the atmosphere to allow to reach very high levels of energetic efficiency.
Given the very cold climate in the city there will also be high-performance condensation boilers working in place of the heat-pump refrigerators when the outdoor temperature goes below the "energetic convenience" level.
This value is reached when the heat-pump uses more energy than the condensation boiler.
Variable flow-rate distribution of fluids allows to minimise the pumps power consumption.

The air outlets will be equipped with electronic filters to reduce the particulate levels in both the supply and the treated air.

The rainwater drainage system foresees, after a first-fall rainwater separation, a storage system for soil irrigation and toilet flush-boxes.

All-air conditioning systems will supply the court-rooms and mixed water/air systems will cover the other areas.

A CCTV system will match the perimeter of the building and watch over the main and secondary entrances; an intrusion detection system will equip all the access doors, all the window-frames at the lower levels and the perimetrical fence.
Where required a badge access system will be provided.
