将沉浸式虚拟环境 (IVE) 与受控环境相结合是在建筑设计过程中分析人体热体验的潜在解决方案。该领域的现有研究尚未充分分析涉及使用热状态投票和生理反应或季节影响的稳定舒适和不舒适温度条件的场景。通过将 IVE 与气候室（在本研究中称为混合 IVE (MIVE)）相结合，进行实验来检验以下假设：与现场体验相比，参与者的虚拟体验不会显着改变他们的热体验。响应变量是控制温度分布、热状态投票（温度步骤 18.3 °C、23.8 °C 和 29.4 °C）和生理反应（心率和皮肤温度）。结果表明，前两个响应变量在 MIVE 和原位设置之间没有显着差异（除一种情况外）。由于头戴式显示设备的发热，大多数情况下MIVE实验中的平均前额皮肤温度明显高于原位实验。然而，皮肤温度的这种差异似乎并没有影响一般热状态投票。此外，在 MIVE 和现场设置之间还观察到某些位置的显着皮肤温度差异。
Combining immersive virtual environment (IVE) with a controlled environment is a potential solution for analyzing human thermal experience during building design. Existing studies in this field have not adequately analyzed scenarios involving stabilized comfortable and uncomfortable temperature conditions using both thermal state votes and physiological responses, or the influence of the seasons. By combining IVE with a climate chamber, called mixed IVE (MIVE) in this study, experiments were conducted to test the hypothesis that participants' virtual experience did not significantly alter their thermal experience compared to theirin-situexperience. Response variables were thecontroltemperature distribution, thethermal state vote(at temperature steps 18.3 °C, 23.8 °C, and 29.4 °C), andphysiological responses(heart rate and skin temperature). The results show that the first two response variables were not significantly different between the MIVE andin-situsettings (except for one case). Due to the heat development of the head mounted display device, the mean forehead skin temperature in the MIVE experiments was significantly higher than that in thein-situexperiments in most cases. However, such difference in skin temperature did not seem to affect general thermal state votes. In addition, significant skin temperature differences at some locations were also observed between the MIVE andin-situsettings.
