Footprint Analysis

This paper presents a case study on the carbon footprint of a fibre reinforced polymer (FRP)-incorporated pedestrian bridge in comparison with a conventional prestressed concrete (PC) one. The CO2 emission is used as an index and calculated for both the material manufacturing and the construction processes. It is shown that using an FRP-incorporated pedestrian bridge to replace a conventional prestressed concrete (PC) bridge may reduce the CO2 emission by 18% and 70%, respectively, during the material manufacturing and construction periods, leading to a total reduction by about 26%. Such reduction is expected to be more significant if the life-cycle CO2 emission is accounted for, since the former type of bridge is free of corrosion and almost maintenance-free. Therefore, FRP-incorporated bridges may become a more competitive alternative to conventional reinforced concrete (RC) or PC ones with the increasing attention paid on the sustainability and environmental friendliness of construction industry by our society.

Proper Design

Purpose The purpose of this study is to investigate the energy efficiency and life cycle carbon footprint of temporary homes in Japan after the Great Eastern Tohoku Earthquake in 2011. Design/methodology/approach An energy simulation and life cycle assessment have been done for three alternative shelter models: prefabricated shelters, wooden log shelters and sea container shelters. Findings Shelter materials have a very high share of life cycle emissions because the use period of temporary homes is short. Wooden shelters perform best in the comparison. The clustering of shelters into longer buildings or on top of each other increases their energy efficiency considerably. Sea containers piled on top of each other have superb energy performance compared to other models, and they consume even less energy per household than the national average. However, there are several gaps of knowledge in the environmental assessment of temporary homes and field data from refugee camps should be collected as part of camp management. Originality/value The findings exemplify the impacts of the proper design of temporary homes for mitigating their energy demand and greenhouse gas emissions.
