CIRCULAR CONSTRUCTION. RETHINKING CONSTRUCTION PROCESSES AND ENERGY CONSUMPTION IN CONSTRUCTION AND BUILDABILITY TRANSFORMATION

This article includes the fundamental criteria and principles of circular construction, the 7R Circular Building Strategy, the circularity chains involved in Sustainable Construction, the criteria for circular construction designs, the criteria for circular construction materials and examples of innovative construction technologies. [...] Carlos.bohorquez@medellin.gov.co BASIC CRITERIA TO BE CONSIDERER IN CIRCULAR CONSTRUCTION -To Implement new construction processes: Reduction of earth excavations and land cuts, use of lower volumes in structural elements, use of modular and prefabricated elements, promotion of the inclusion of renewable components in construction and therefore the consumption of less energy, their optimization an. [...] An important aspect to take into account from the conception and design of construction works is the carbon footprint of the construction techniques and elements to be used and the materials or components to be used. [...] (Life Cycle Assessment – Environmental Declaration of the Product or Material) It is defined by the life cycle of Carbon in relation to the Materials and the energy used in the construction processes. [...] OTHER ISSUES FOR FURTHER CONSIDERATION TO INCLUDE THE COSTS OF ECONOMIC EFFECTS OF ENERGY EFFICIENCY IN CIRCULAR CONSTRUCTION: Energy efficiency programs include, among others, the identification and correction of losses, the reduction of energy consumption at peak hours, and the reduction of the energy rebound effect and the general decrease in consumption in buildings.
