| Sumario: | The aim of this study is to understand the relationship between initial embodied, operation energy consumption and CO2 emissions and recycling/reuse potential of industrialized and conventional systems in architecture. This investigation establishes the impacts of residential buildings and shows the role of early design decisions on this subject. The whole process, from design phase to demolition is evaluated. In this study, general properties of residential buildings in Catalonia, classification according to principal construction types and major features related with energy/emission character are investigated. Recently constructed residential buildings’ properties are compared with three created cases. Reference building is selected as a recently constructed industrialized modular system building in Catalonia and considered as medium-lightweight with minor revisions from the original module. Other two cases are created as lightweight industrialized and heavyweight conventional system with the same building plan of reference case. Three cases are evaluated respect to each other, since thermal masses are different. Impacts of trends in the three cases on the energy consumption and emissions are examined. The relationship between initial embodied energy and life time (fifty years) operational energy are evaluated using unit data values and heating/cooling demand calculation. Recycling/reuse potentials are evaluated with and introduced methodology. However, unit data values are used and indirect effects are not considered. At the final part of the study, total embodied carbon at the end of the life time for three cases is compared and possible savings are discussed for future applications. Furthermore, required recruitment possibilities for industrialized modules and for conventional system are proposed according to the results of the embodied and operational carbon, as well as the possible savings by recylcling/reuse. Transport and packing system rating is discussed and future recommendations are made. |
