Data for: Trade-off between the economic and ecological impact of different decarbonisation strategies for residential buildings

“E3 - A parametric model to evaluate trade-offs between the Energetic, Economic, and Environmental lifecycle performance of building projects” is a spreadsheet tool for the calculation of the environmental and economic lifecycle impact, as well as the Pareto optimal evaluation method, of strategies for residential buildings. Quantities of the building´s components (building geometry, materials or assembly types and their sizes, number of flats, number of tenants, and so on) are retrieved from technical plans. Calculation of quantities is performed according to the definitions described in DIN 277-1. Quantities and parameters for the building services components are determined by balancing all energy load (demand) profiles with energy generation profiles. Energy profiles are modelled in the E3 tool on an hourly basis (that is, using 8,790 points) for a typical year of operation. Energy load profiles determine the peak load for building services, which is used to determine each component´s required size. For photovoltaic cells and solar thermal collectors, peak load and size are constrained by the available surface. All other components can be modularly scaled to any size. Finally, energy generation profiles are used to determine primary energy use for building operation. Energy load profiles include heating energy demand, warm water demand, user power demand, and auxiliary power demand. Heating energy demand is calculated by assessing the thermal quality of the building envelope as a factor of temperature (W/K) over time (h). The thermal quality of the building envelope is found by balancing transmission losses through the building envelope and ventilation losses against solar thermal energy gains and internal heat gains. Energy generation profiles are modelled using factors to represent the efficiency of transforming a primary energy source (photons, solar thermal energy, gas, or grid power) in delivered energy (thermal energy or electricity).“E3——一款用于评估建筑项目全生命周期内能源、经济与环境性能权衡关系的参数化模型”是一款面向住宅建筑策略的电子表格工具，可计算其环境与经济全生命周期影响，并开展帕累托最优（Pareto optimal）评估。 建筑构件相关参数（如建筑几何形状、材料或装配类型及其尺寸、公寓数量、租户数量等）均从技术图纸中提取。工程量计算依据DIN 277-1中规定的定义开展。建筑设备构件的工程量与参数通过匹配所有能源负荷（需求）曲线与能源发电曲线来确定。能源曲线在E3工具中以典型运行年为基准，按小时粒度建模，即基于全年8790个小时数据点进行建模。能源负荷曲线用于确定建筑设备的峰值负荷，以此确定各构件的配置规格。对于光伏电池（photovoltaic cells）与太阳能集热器，其峰值负荷与配置规格受限于可用安装表面积；其余所有构件均可模块化缩放至任意尺寸。最终，通过能源发电曲线计算得到建筑运行阶段的一次能源消耗量。 能源负荷曲线涵盖供暖能耗需求、生活热水需求、用户用电需求及辅助用电需求四类。供暖能耗需求通过评估建筑围护结构的热性能随时间（以小时为单位）的温度系数（W/K）进行计算。建筑围护结构的热性能通过平衡围护结构传热损失、通风损失与太阳能得热、内部得热的差值得到。能源发电曲线通过转换因子建模，用于表征一次能源（光子、太阳能热能、天然气或电网电力）向终端能源（热能或电能）转换的效率。
