建筑物公共区域能量有效性确定

公共建筑中公共区域人流量变化很大,能量的需求也应随着人流量的变化而变化。但传统模式下能量输出却很少考虑人流量的变化,这就造成了部分能量无效。如何评价能量有效性,以减少能量浪费是建筑节能需要研究的问题。提出了能量利用效率概念,用于判断人对能量的利用程度,给出了能量利用效率的计算方法。在某医院公共候诊区进行了工程实验,对比实验前后的能耗状况发现,能量利用效率能够评估能量有效性的状况,以提高能量利用效率为控制目标,可以较大幅度提高建筑物公共区域能效。

Effectiveness of Energy use in Public Area of Buildings

The flow of people changes very greatly in the public areas of public buildings,so the energy demand should also change with the flow of people.However,under the traditional model,the pedestrian flow is rarely considered when accounting energy output,which causes some of the energy invalid.How to assess the energy efficiency to reduce energy waste is an emergent problem to be solved for building energy conservation.The concept of energy utilization efficiency is put forward to judge the degree of utilization of energy,and the formula for calculating energy utilization efficiency is also provided.In a hospital public waiting area,a lot of experiments have been carried out.By comparing the energy consumption before and after the experiments,it is found that energy utilization efficiency can assess the effectiveness of energy.And to improve the energy efficiency of buildings greatly in public areas can be realized by promoting the energy utilization efficiency.
