Local Climate Zone (LCZ) classification has been ex-tensively used to classify urban and rural landscapesin cities, supporting various types of climate assess-ments, including urban temperature studies. UsingLCZ method, urban areas are predominantly classi-fied based on features related to the terrain and urbanmorphology, but neglecting to account for the hetero-geneity present in similar urban morphologies due todifferent building occupancy behavior (e.g. residen-tial, office, retail). This has a direct impact on thespatial distribution of anthropogenic heat and on ur-ban heat islands assessment. To illustrate this detri-mental aspect, we analyze metered data from morethan 13,000 buildings’, together with a LCZ classifi-cation map developed for Singapore and the Singa-pore Master Plan, that classifies Singapore accordingto its Land Use. We evaluate and compare the spatialvariability of buildings’ Anthropogenic Heat (AH) be-tween the current LCZ and the LCZ-Land Use (LCZ-LU) method, and identify the more error-prone cases.We show that most of the variability within a LCZ isattributed to significant differences in the Energy UseIntensity (EUI) of different occupancy types. As a so-lution for this problem we propose a sub-classificationscheme which provides a more accurate estimation ofthe AH. Show more
