Course content

Every builder wants to build well and cheaply. But where is the economic optimum? Is investing in ambitious energy efficiency measures affordable?
In this learning module, we will optimise the energy efficiency of a single-family home, which was originally designed to meet the minimum legal standards, to the passive house standard and compare the additional and reduced costs for construction and operation. On this basis, we will calculate the net present value and annuity of the optimised building variant step by step in order to be able to make informed statements about its economic efficiency.

Along the way, you will learn all the important basics and formulas you need to calculate the profitability of your own projects in the future. You can also download all the Excel tools and use them in your everyday work.

The German Energy Agency (dena) recognises the "Calculation of economic efficiency" learning module with 6 UE (teaching units).
