Urban heat, material stocks, neighbourhood care and the experience of walking. Explore the research, maps and tools behind my practice. Each case explains the question, my contribution, what exists and its limits.
Urban research.
Four substantial studies connecting environmental observations, urban systems and decisions. Published work sits alongside the ongoing heat-model re-audit.
A co-authored method and maps estimating material stored in buildings.
Buildings coloured by estimated total material stock, in tonnes: pale yellow lowest, dark teal highest. Apeldoorn material-stock map, 2022. Map: Gerardo Ezequiel Martín Carreño. Buildings: 3DBAG; material intensities: Sprecher and colleagues. Basemap: CARTO and OpenStreetMap contributors. Screenshot: 11 October 2026.

A spatial allocation study of connected neighbourhood areas for Barcelona’s home-care service.
Proposed social superblocks (green), each a grouping of mobility superblocks (thin red lines), with district boundaries dashed. Legend, in Spanish: Distritos, districts; Supermanzanas sociales, social superblocks; Supermanzanas de movilidad, mobility superblocks. From Gerardo’s UPC master’s thesis, 2020, p. 29; research developed at BCNecologia, Barcelona’s urban ecology agency. Original map and legend retained.
How a pilot page could link Amsterdam’s municipal waste flows (Sankey, top) to local organisations that could use them (KUMU map, bottom). Amsterdam alpha demonstrator, CENTRINNO D2.2, 2022, p. 44, Figure 31. Shared research figure by Metabolic and pilot teams; co-authored deliverable. Basemap: MapTiler and OpenStreetMap contributors. The two source screenshots retain their original boundaries.
Walking and cartography.
A commissioned walking workshop and a south-up atlas. A practice of observing places and questioning how they are represented.
Five-stop route map for the Lower Lea walking workshop of 13 May 2026: meeting at Hackney Wick station, five stops, then the workshop at Barge East. Map: Gerardo Ezequiel Martín Carreño.
A map I made as a student at the 2023 MIT Senseable City Lab summer school with AMS Institute, setting air-quality readings beside Amsterdam’s buildings and street observations.
