Project Description The complete work consists of 10 A0 format tables, a presentation video, and a detailed report. In this thesis work, it was possible to analyze the principal Virtual Environment Modeling (VEM) software in architectural design addressed through computational method tools. All the analyses are applied on a Renaissance Palazzo in Florence, Italy. Following a detailed survey, a 3d model is designed to be the subject of the analyses.
Objectives and Challanges
1. To have more detailed and specific information on the project area, a Geographic framework was done through GIS software. All the metadata (shapefile, Raster images, DSM and DTM) were collected from Regione Toscana, (Sistema Informativo Territoriale ed Ambientale). This geographic information is official data validated by law. The first aim of this analysis was to understand
The study covers different scales: from a wide scale where the model was georeferenced through GIS software to the detailed analyses on thermal characteristics of building elements and materials. The aim of the work is to observe the phenomena that insist on this building and quantify them with the use of software of analysis and certification (detailed computational methods, semi steady, simplified). This thesis work proposes a methodology that can in the future grant to accomplish a detailed understanding of environmental aspects of historical buildings through simulation results.

GPS and laser distometer survey of the building was performed in order to evaluate the veridicity of the collected historical data and to georeference the model of the building for further analyses with an error factor that ranges from 10 to 50 cm.
This was possible because the GPS mapping system, stores data in a GIS compatible format and can be exported in several other formats, such as AutoCAD, *.dxf, ARC/INFO, Arc.CAD, ERDAS.

The first aim of the whole work is to compare BPS and their capabilities to help the design process. In this part of the work, a series of building components, such as windows, doors, walls, floors and roofs has been modeled and analyzed using the built-in material library. Ecotect Analyses and Design builder was used to model components and calculate results. Interesting results on differences between software, both on the modeling and calculation part, were sorted out. Furthermore, calculated properties were compared with law minimum performance requirements.

Weather toll allow the user to use an incredible amount of useful data to implement the understanding of the project location. Data are offered dynamically including both 2D and 3D graphs as well as wind roses and sun-path diagrams. After an acquired consciousness of the weather and climatic issues, it was possible to run various simulations. In these pages are presented urban scale CFD, solar access and shadow analyses. It  was possible to assess graphically and numerically, different sensible case studied situations.
