Task - Architectural Design and Technical Detailing
Located in heart of milan at close promiximity to the centrale station and well connected with the Milan city network. The site i s analysed on multiple layers inorder to help us understand and identify the key potentials and shortcomings. The layers analysed was void study analysis, accessibility and landuse analysis. and following conclusions is shown in the figures below.The key understandings are the site is located in a dense volume space with less open space ratio and narorw lanes with limited daylight in the area.
Optioneering is a process of balacing by proposing and comparing different options to select the most optimized option in terms of energy performance, daylight, cost, embodied carbon, ..etc.

DAYLIGHT ANALYSIS
After applyiing vertical, results show that we got better annual sun exposure and a good opportunity to reduce glare probability on the two views of the co-working space. For each one we choose the seats near the glazing as they are closere to overlit areas.

NE US NEXUS - FINAL THESIS PROJECT
Exploring Advanced Design and Fabrication Methodologies for a Free-form Shading Element through Algorithmic Programming, Robotics and Machine Learning
Academic Work _Group Work
Task - Facade Design, computational design, optimization, fabrication
The project Investigates the exploration of advanced fabrication methodologies for complex, free-form shading elements in building facades. Emphasizing the integration of algorithmic programming, robotics, and Augmented reality (AR) and performance based analysis. Through detailed case studies and practical implementations, we demonstrate that employing advanced technological methods in fabrication not only streamlines the design-to-fabrication pipeline but also significantly enhances the adaptability, sustainability, andperformance of architectural facades.
