Virtual Reality application in holistic investigations for energy and cost-saving building design, aimed at humans’ well-being and performance, is still emerging and needs validation.

In this study, tests in real and virtual scenarios of an office room were performed, investigating the impact of three walls colours (red, white, blue) and two indoor air temperatures (17–22 °C) on 23 participants’ work productivity (through a proofreading task) and thermal and visual sensations (through surveys). The first goal was the comparison of the results obtained in the real and virtual settings; the second one the assessment of the effect of walls’ colour and temperature levels on the mentioned variables in each environment. Statistical analyses were then performed “between groups” (Wilcoxon and t-tests, among datasets of the two environments) and “within groups” (ANOVA and Scheirer test, within each environment).

The study revealed no statistically significant variations in productivity and sensation votes, thus supporting the suitability of VR as a proper research technology in this domain. The study also demonstrated no statistically significant effects of colour and temperature on productivity and comfort results within the tested settings. Future investigations should involve a wider range of temperatures and colours and address a wider subjects’ sample.

虚拟现实在能源和节约成本的建筑设计的整体调查中的应用，旨在人类的福祉和表现，仍在出现并需要验证。

在这项研究中，在办公室的真实和虚拟场景中进行了测试，调查了三种墙壁颜色（红色、白色、蓝色）和两种室内空气温度（17-22°C）对 23 名参与者的工作效率的影响（通过校对任务）以及热和视觉感受（通过调查）。第一个目标是比较在真实和虚拟环境中获得的结果；第二个是评估墙壁颜色和温度水平对每种环境中提到的变量的影响。然后在“组间”（Wilcoxon 和 t 检验，在两种环境的数据集中）和“组内”（ANOVA 和 Scheirer 检验，在每个环境中）进行统计分析。

该研究显示，生产力和感觉投票在统计上没有显着变化，因此支持 VR 作为该领域的适当研究技术的适用性。该研究还表明，在测试环境中，颜色和温度对生产力和舒适度结果没有统计学意义的影响。未来的调查应涉及更广泛的温度和颜色，并针对更广泛的受试者样本。
