A novel PMV index based productivity model is derived and it is used to estimate the effectsof different thermal conditions on productivity. Past research findings are used as inputs in thecreation of this productivity loss model. The PMV equation is useful to predict productivityloss that is due to the rate of change in thermal conditions. Using the model prediction, thetheoretical maximum level of productivity occurs when the PMV value is -0.21. Admitting a30% productivity loss in typing-task, the model predicts PMV value ought to be at least+0.63. In a similar case in thinking-task, the model predicts a higher PMV value of +1.28.For the productivity loss of 30%, the difference in temperature range can be a small margin of2-3C in typing tasks and a wider range of 4-6C in thinking tasks depending on the level ofthe neutral temperature.
