Abstract:

In the study on functional low-carbon ergonomic validity in buildings, ergonomic validity is different from resource validity which is easy for quantitative analysis. To eliminate the complexity and uncertainty impacts of human factors on quantitative study, it proposes a method of building a parameter of ergonomic validity —multi-effect time by using cardiotachometer to record heart rate change,being used to evaluate the functional low-carbon ergonomic validity targeting at the ontological characteristics of kitchen. This method is used to determine the physical consumption intensity (multi-effect) through heart rate incremental relation based on the principles of physiology and ergonomics, and to confirm the ergonomic validity of environmental factors by the time to complete standard work as well as multi-effect quantitative analysis. The test results show that, under the kitchen operating conditions, the multi-effect(ME) can properly reflect the real-time status of the operator and is easily operated; the parameters obtained are not significantly related to the physiological status of the operator, and multi-effect time(MT) is sensitive to the physical consumption brought about to the operator due to kitchen environmental factors; thus, it can be taken as an objective index,which is simple and easy to operate in residential kitchen functional low-carbon evaluation.
