METHODOLOGY FOR EVALUATING THE EFFECTS OF INSTALLING ROOF SHADES IN REEFER CONTAINER AREAS AND POSSIBILITY OF VERSATILIZATION

Abstract

 There are few empirical studies on energy conservation and decarbonization measures for reefer containers (RCs), which account for a particularly large share of energy consumption in ports, and the gap between research and practical application is a challenge for port decision makers. In this paper, a simulation model to evaluate the effect of installing roof shades in RC areas at the Hakata Port was used to estimate the energy saving effect, which was then used to evaluate the economic benefits and the possibility of applying the model to other areas was evaluated. The results show that the energy conservation rate could be larger in winter than in summer, and in cold regions than in warm regions, because the effect of solar radiation is relatively small in summer and in warm regions. The results of this paper are expected to contribute to the energy conservation and decarbonization of ports around the world, as they provide a powerful tool for port decision makers to make a preliminary assessment of roof shade installation.
