BUILDING PERFORMANCE SIMULATION: A COMPARISON BETWEEN TWO DESIGN PROPOSALS FOR A RESIDENTIAL BUILDING

The experimental stage of research is here described about architecture that adopts the BIM and BPS processes: the results of the Energy Simulation for two different design approaches aimed at improving the energy efficiency of a building are compared.
As a first step, a residential building in Italy is selected and the relative information model is processed on which two proposals will be made; in the first, solutions based on conventional intervention procedures are proposed, among those most widespread on Italian territory, while in the other, solutions based only on bioclimatic architecture principles, mostly with passive systems, are suggested. The two alternatives are compared, and their pros and cons are evaluated. The goal is to provide investigation and design methods as well as tools to be adopted already from the early stages of project definition and above all to encourage the use of bioclimatic technologies so as to minimize the use of mechanical air conditioning systems. The article is aimed to show that in architectural design, such a cooperation between different actors, including the BPS experts, which can lead to an increase in the energy performance levels of the architectural product, can be appropriate.
