Wärmekataster Wärmebedarf HamburgHeat Cadastre – Heat Demand Hamburg
Published by LGV Hamburg
This WFS API provides the Heat Demand dataset of Hamburg's heat cadastre, published by LGV Hamburg (Landesbetrieb Geoinformation und Vermessung). It presents the useful heat demand (NWB), i.e. the energy required for heating and hot water, for Hamburg's building stock in aggregated form at cluster level, distinguishing between renovated and unrenovated buildings. Data layers cover absolute and specific heat demand per building and per building block, as well as heat density values. The dataset supports energy planning, heat supply analysis, and assessment of renovation potential across Hamburg's urban area.Der Datensatz „Wärmebedarf“ des Wärmekatasters stellt den Nutzwärmebedarf (Abk.: NWB - Wärmebedarf für Heizung und Warmwasser) des Hamburger Gebäudebestandes in aggregierter Form dar. Der (Nutz-) Wärmebedarf des Hamburger Gebäudebestands wird auf auf Cluster-Ebene angezeigt. Man kann zwischen zwe...
