Heat cadastre Heat demand Hamburg

The data set “Heat requirement” of the heat cadastre represents the useful heat demand (Abk.: NWB – Heat demand for heating and hot water) of the Hamburg building stock in aggregate form. The (benefit) heat demand of the Hamburg building stock is displayed at the building block level and at the cluster level. You can also choose between two stages of refurbishment: 1. “Unrenovated” implies a building condition that has no thermal modernisations (apart from simple window replacement) 2. “Refurbished” adopts a conventional refurbishment of all buildings (according to ENEV 2014). The presentation and categorisation can be selected as follows: 1. Total needs of all residential and non-residential buildings of the cluster or building block; in megawatt hours per year [MWh/a] 2. Specific heating requirements of residential buildings (clusters); in kilowatt hours per square metre usable area and year [kWh/m² a] 3. “Heat density in the building block”; Total demand of all residential and non-residential buildings (such as No.1) divided by the floor area of the respective building block; in kilowatt hours per square meter of building block floor area and year [kWh/m² a] Detailed information can be found in the heat cadastre manual."热需求（Heat requirement）"热地籍（heat cadastre）数据集以聚合形式呈现汉堡建筑存量的有效热需求（缩写：NWB——供暖与热水热需求）。汉堡建筑存量的有效热需求以街区单元（building block）与集群（cluster）两级粒度进行展示，同时支持选择两种翻新阶段： 1. "未翻新"：指代未实施热力现代化改造（仅允许进行简易窗户更换）的建筑状态； 2. "已翻新"：指代所有建筑均采用符合ENEV 2014标准的常规翻新方案的建筑状态。 展示与分类方式可从以下三种中选取： 1. 集群或街区单元内全部住宅与非住宅建筑的总热需求，单位为兆瓦时每年 [MWh/a]； 2. 住宅建筑（集群）的单位供暖热需求，单位为千瓦时每平方米可使用面积·年 [kWh/m²·a]； 3. "街区单元热密度"：将集群或街区内全部住宅与非住宅建筑的总热需求（同第1项）除以对应街区单元的建筑面积，单位为千瓦时每平方米街区建筑面积·年 [kWh/m²·a]。 详细信息可查阅热地籍手册。
