Modeling the cost effects of the indoor environment

Several previous calculations have shown that many of the measures taken to improve indoor air quality and climate are cost-effective when the potential savings are included into the calculations as benefits. However, general models on how to estimate the cost-effectiveness of various measures and strategies are still missing. This paper presents approach with which the ratio of savings in any of the costs of owning and operating a building can be compared with the real cost at risk which is reduced worker performance. An ISIAQ Task Force titled 'The effects of the indoor environment on productivity in office environments' coordinates the international development of the model.
