Overall cost/benefit analysis for hybridGEOTABS buildings

We have performed a detailed cost/benefit analysis (CBA) for the four case study buildings of our project – Haus M, Líbeznice, Infrax/Fluvius and Ter Potterie. For the CBA, we followed the EC directive number 244/2012 (1), which brings templates and methods to calculate the global financial cost in the sense of the net present value. The CBAs have been calculated according to national price levels and specific parameters (such as discount rate or primary energy conversion ratio). For all the case study buildings, the hybridGEOTABS solution with MPC was recommended – with slightly higher global financial cost, this solution ensures much lower environmental impact than the baseline variants. In addition, a variant with added photovoltaic panels was also considered, and this brought additional decrease in both global financial value and environmental impact in terms of ETS.
