With the building simulation plugin Energy & costs A simple calculation is made of the payback time of measures to your existing building. By identifying the investment costs and the savings that the investment will generate, it can be calculated how long it takes for the investment to be recouped.
To determine the savings, a comparison must be made between the current and the desired situation. This equation can be made by entering the monthly gas and energy consumption of the existing building of the past year and in addition all the correct data needed to carry out the building simulation. When the results of the building simulation and the values entered correspond, a payback time can be calculated using the building simulation data that corresponds to the model with the investment.
With the help of clear graphs you can see at a glance whether the meter readings match the model in Elements and then you can see what the payback time is.
