All devices are thus easily accessible, both for use and for main-
tenance, while keeping the room under the reinforced concrete
beams free of technical equipment.
ROOF TECHNOLOGY
Production of photovoltaic electricity
In addition to the electricity produced by the gas-fired CHP unit
(producing 20kW of power), the gym roof supports 250 m² of
photovoltaic solar panels with a peak performance of 30 kWc.
The panels, resting on a galvanised steel construction, are inclined
at 10° to the horizontal.The inverter is in the technical room on the
north side of the fourth floor.
Solar production of hot water
Production of hot water for WCs and showers includes the use of
three sets of parallel 15m² solar panels also located on the gym roof. (see Chapter 6)
Details of the downpipes in the vehicle garage.
These panels, also resting on a metal construction, are inclined
at 35° to the horizontal.
The solar panels cover 20% of the fire station’s annual hot water needs
(up to 35% in the summer months).This represents a yield of 60%.
Lightning protection
Outdoor lightning protection is based on the Faraday cage princi-
ple.The roofs are criss-crossed with 50mm² aluminium conductors
15 metres apart and earthed by means of the metal facades.
Over 25 metres high, the training tower has two 10-metre antennas
on top, also earthed.
These systems are complemented by indoor lightning protection
devices integrated in the switchboards.
