Nowadays we spend most of time indoors and therefore building planners must provide best possible indoor environmental quality (IEQ) for living and working in the most energy efficient way. While living comfort can be predicted with the set of standardized physical variables, the evaluation of productivity is still not included in building design by default. The aim of the study is to present i) the experimental evaluation of performance of mental work of test subjects (age between 22 and 63 years) at controlled indoor environment in four IEQ domains – thermal, indoor air quality, lighting and noise exposure; ii) the statistical evaluation of three tests of mental work performed by test subjects (d2, arithmetical, Baddeley test), (iii) the method for ranking of IEQ based on physical variables and ranking the impact of physical variables on productivity of mental work as a basis for developing integral single score metric, (iv) a procedure to incorporate the integral single score metrics into dynamic modelling within the selected BIM tool. No statistically significant differences in scores of tests of mental work regarding to the gender and age of test subjects was found, while impact on productivity was found even if indoor environment conditions were maintained within the range of standardized quality classes (I–IV). Case study shown that indoor environmental quality metric significant increases by implementing energy efficiency measures, while smart operation of building technical system is needed to establish high productivity of mental work as well, those justifying the multi-approach of building design.

建筑信息模型中室内环境质量和认知性能评估与积分指标的耦合



如今,我们大部分时间都在室内度过,因此建筑规划师必须以最节能的方式为生活和工作提供最佳的室内环境质量 (IEQ)。虽然可以使用一组标准化物理变量来预测居住舒适度,但默认情况下,生产力评估仍未包含在建筑设计中。该研究的目的是介绍 i) 在受控室内环境中对测试对象(年龄在 22 至 63 岁之间)的脑力劳动表现的实验评估,涉及四个 IEQ 领域——热、室内空气质量、照明和噪音暴露;ii) 对测试对象进行的三项脑力劳动测试的统计评估(d2、算术、Baddeley 测试),(iii) 基于物理变量对 IEQ 进行排名的方法,并将物理变量对脑力劳动生产率的影响进行排名,作为开发整体单一分数指标的基础,(iv) 将整体单一分数指标纳入所选 BIM 工具内的动态建模的程序。在测试对象的性别和年龄方面,脑力劳动测试的分数没有发现统计学上的显着差异,而即使室内环境条件保持在标准化质量等级 (I-IV) 范围内,也发现了对生产力的影响。案例研究显示,通过实施能源效率措施,室内环境质量指标显着提高,同时还需要建筑技术系统的智能运行来建立高脑力劳动生产力,这证明了建筑设计的多方法的合理性。
