Abstract
Retrofit, not demolish. The larger part of the residential buildings constructed in Italy between the 1950s and the 1980s is made up of buildings that consume large amounts of energy and offer little comfort levels in return. Tearing down and rebuilding is an option that is not only taxing on the environment but also requires a long-term living alternative for the tenants. Retrofitting on the other hand has less environmental impact and limits the tenants' inconvenience. Digital analysis and design tools allow us to foresee surrounding conditions and the effectiveness of the shell. However, modelling and analysing multiplied by hundreds of housing units has a design cost that is seldom sustainable. The challenge is that of creating a tailored design for large numbers: different conditions found in each unit should lead to a case-specific design therefore increasing cost. Is it possible to imagine a careful and varied design for 140 projects, without its cost? The focus of the research is on specific objectives such as improvement of energy saving performance, thermal and visual comfort for each unit and a renewed image for the building. The analysis carried led to an Irradiance mapping through Autodesk Vasari leads to the choice of sample units. These are then further analysed and mapped for thermal dispersion using EnergyPus+OpenStudio software and the Lighting Analysis add-in for Autodesk Revit for daylighting. The results show positive and negative extremes within the facade. The results are then used to create an envelope system of architectural parametric components, with different performance levels regarding glazing area and insulation. These components can vary their dimensions and thermal properties and can be combined to create the facade. The “re-composition” phase is based on finding a compositional rule within the facade patchwork through the information given by the Irradiation maps.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
