(Conversion from Oil to Gas and Upgrading of the Heating Systems in the
Objective: To examine the feasibility and, assuming it is
positive, to undertake the necessary technical assessment for the transition
from petrol to natural gas for heating buildings on the A.U.T. campus.
LHTEE Contribution: The existing situation of the A.U.T.
building unitsí heating systems was recorded and the possibility of connecting
boiler rooms was examined. Based on the data gathered, the alternative
possibilities were assessed and the optimum route for the natural gas network
was chosen. The route for the natural gas network was defined and planned in
every detail. Following on from this, the burners and all the necessary
regulatory and monitoring systems were specified. The cost of the network and
the equipment was determined, based on the measurements and specifications
mentioned above. An investment analysis was carried out, determining that the
required investment for the implementation of the programme, amounts to 120
million GDr. and is expected to be amortised in less than 3 years. At the same
time, the reliability and availability of the heating system will improve,
whereas CO2 emissions arising from the operation of the system, which is the
largest single building unit in the centre of Thessaloniki, are expected to
decrease by 23% and fume emissions will fall to zero.
