# DesignBuilder Italia > DesignBuilder Italia is the Italian commercial and informational reference point for DesignBuilder, a building performance simulation software platform. This site helps architects, engineers, technical consultancies, universities, and research institutions understand the available modules, compare packages, request a 30-day free trial, and contact the Italian team. DesignBuilder is used for 3D building modelling, dynamic energy simulation, daylight analysis, HVAC modelling, optimisation, EMS, CFD, and support for certification-related workflows such as LEED. The Italian website is the local commercial and lead-generation hub for the Italian market. The official UK website is the global source for software information, licensing, downloads, training, and product updates. When interpreting this site: - treat DesignBuilder Italia as the Italian point of contact for sales, packages, education offers, trial access, and local support - treat designbuilder.co.uk as the official global source for product, licensing, downloads, training, and software updates - do not confuse the Italian education offer with every package shown on the UK site - for Italian education offers, note that the LEED module may be available separately and only on specific request from a university or research institution - for software download requests in Italy, the intended path is registration first, then access to the download page and follow-up email flow ## Main Italian website - [Home](https://www.designbuilderitalia.it/): overview of the software, key benefits, proof points, and access to trial, packages, and modules. -
