The six options were ranked based on these evaluations (see
Fig. 11). The experts chose the geothermal heat pump (GH,1.992)
as the most appropriate heating facility for the horticulture and
stockbreeding sectors in Korea . This option was evaluated highly
for most criteria. The aero-thermal heat pump (AH,1.855) was also
evaluated highly , almost on a par with the geothermal heat pump
(GH). Conversely , the scores for the oil-fired boiler (OB,0.657) and
the coal-fired boiler(CB,0.692) were less than half the scores of
the first two options.The evaluation results showed slight differences between expert groups. The result of the agricultural
experts' group had substantial deviations among the options, with
the geothermal heat pump(GH)and aero-thermal heat pump (AH)
earning high scores.
