EU generate 25-30% of all waste from construction and demolition (C&D) activities, much of which remains underutilized or sent to landfills.
Context
whilst global temperatures are rising towards +4°c, building facades are a main contributors to the urban heat island effect within cities.2050 about 70 % of the world’s population will live in cities.The building sector globally consumes a significant amount of energy for heating and cooling. In fact, about half of the global cooling load is due to solar gains, which means that buildings need a lot of energy to stay cool during hot weather.
State of the Art
Centre Active Bricks, Technical university Munich
The project looked into possibilities for improving the local microclimate in urban areas by creating self-shaded building facades with reduced solar exposure. we investigated whether we can apply digital design and robotic fabrication technology to improve the exterior facades of buildings directly.
The project aimed at integrating the potentials of computational design, climate simulation and robotic fabrication with the activation of climate-active properties of bricks in building envelopes. A prototype of this concept was produced together with students at 1:1 scale at the Kreativ Quartier in Munich. We explored whether the creation of customized site-specific self-shading effects in the external facades of buildings can reduce solar exposure and thus decrease the storing and radiation of heat to improve the ambient climate in urban areas

Research Question
How can repurposing construction waste, combined with robotic fabrication, address solar radiation impacts to create parametric, functional facades?
Methodology
Site Selection Processing
Data Collection
After selecting the site, I took detailed photos and conducted a photogrammetry scan to create an accurate 3D model. This process helped in understanding the site’s geometry and conditions, enabling informed decisions for designing parametric functional facades using construction waste
