根据在商业建筑中进行的十几个不同的案例研究，如果将居住者的在场/缺席考虑到建筑运营中，大约可以节省10%-40%的能源。CB1大楼0.3千瓦/人和CB2大楼0.2千瓦/人，以及另一栋写字楼OB1 1.0千瓦/人，作为入住率和用电量的数据采集点。分析结果表明，总用电量(R2=50%~80%)和插头负荷(R2=70%~80%)与研究建筑的入住率显著相关。研究还发现，居住者对建筑用电量的影响与建筑面积的使用分布成正比。这一发现使得能够建立一个线性方程来估计归一化居住者对以千瓦/人为单位的电力消耗的影响。对于第三栋校园建筑CB3，作为示范建筑，用先前校准的线性方程计算的用电量预测的千瓦/人在实际测量0.53千瓦/人的7%以内。每个居住者的用电量代表了居住者对建筑面积使用类型定义的建筑物用电量的影响的适当和可概括的衡量标准。(C)2016爱思唯尔B.V.保留所有权利。
Approximately 10%-40% of the energy can be saved, if the occupants' presence/absence is factored into the building operation based on a dozen different case studies conducted in commercial buildings. Two campus buildings, CB1 with 0.3 kW/person and CB2 with 0.2 kW/person, as well as one additional office building, OB1 with 1.0 kW/person, served as data collection sites for occupancy rates and electricity consumption. The analysis results showed that both the total electricity consumption (R-2 = 50%-80%) and plug loads (R-2 = 70%-80%) are significantly correlated with the occupancy rates in the studied buildings. This study also found that the impact of occupants on the building electricity consumption is directly proportional to the building area usage distribution. This finding enabled development of a linear equation to estimate the normalized occupants' impact on the electricity consumption in kW/person. For a third campus building, CB3, used as a demonstration building, the electricity consumption calculated with the previously calibrated linear equation predicted the kW/person to Within 7% of the actual measured 0.53 kW/person. The electricity consumption per occupant represents an appropriate and generalizable measure of the occupants' impacts on the building electricity consumption defined by the building area usage type.
