Abstract

Main task in the design phase of the energy refurbishment of a building is to individuate the better solution between technological alternatives related to relevant design factors, like environmental sustainability, product quality and cost of the project. Life Cycle Cost analysis (LCC) is an economic method for evaluating a project or project alternatives over a designated study period. LCC entails computing the LCC for alternative building design or system specifications having the same purpose and then comparing them to determine which has the lowest LCC over the study period. LCC evaluates with the Present-Value calculation method, all the feasible costs for the owner of a facility related to building construction, operations, maintenance, repair and replacement and final disposal. LCC method determines initial and future costs of a building or a building system to be compared to an alternative with the aim of choosing the better design solution. LCC method was recently implemented in the E.U. by the council directive 31/2010/CE-EPBD (Energy Performance Building Directive) and by the regulation 244/2012/EU with the method of Global Cost. Global cost differs from LCC at a macro-economic level mainly because of the addiction of the new cost category of the greenhouse gas emissions cost. The implementation of the Global Cost Method brings into technical building design new dimensions, the economic–based and the time–based, with the aim of energy sustainability of building process and product. The Global Cost method has been developed for a case study of energy refurbishment of a Social Housing of Bologna. The developed study has allowed the comparison between two design alternatives to improve the building energy performances, thus evaluating their efficiency. The Global Cost estimate of the design alternatives allows the project team, the owner, the designer to better evaluate the energy costs and the environmental impacts related to the refurbishment project and the materials used.
