人行为是影响建筑能耗的重要因素,近几年成为建筑能耗模拟领域的研究热点。在过去的几十年中已有大量的相关研究,致力于通过实测建立事件或环境相关的人行为模型,但是,目前的人行为研究中还需要进一步发展,以满足工程实际的需要。本文回顾了人行为研究的研究现状,总结了在研究方法上现存的问题,从数据采集、模型建立、模型验证和软件开发4个从建模到应用的阶段,提出了人行为研究的未来展望。并讨论了人行为研究中尚存在的一些共性问题,例如:在实测中应进一步探讨采样的规模和实验室研究的可行性,建立人行为模型时应明确模型面向的应用层次,合理的数学形式、参数选择的方法、多因素多行为多人的模拟等尚待研究,针对模型的验证应以实际应用为指向确定验证的指标,采取科学有效的验证方法,以及在人行为相关软件的开发中,应定义良好的软件结构和接口,建立统一的描述框架,以相对独立的模块形式实现和模拟软件的交互。希望这些探讨能为将来的人行为研究提供新的思路,以推动人行为和建筑能耗模拟事业的发展。
