Welcome

Welcome to the Website of the modeling tool Invert/EE-Lab!

Invert/EE-Lab is a dynamic bottom-up techno-socio-economic simulation tool that evaluates the effects of different policy packages on the total energy demand, energy carrier mix, CO2 reductions and costs for space heating, cooling, hot water preparation and lighting in buildings.

Invert/EE-Lab includes a database on disaggregated building stock data for all countries of EU-28.

After more than ten years of Invert/EE-Lab application. The Invert/Opt optimization model, Invert/Acc accounting approach, and Invert/CC cost curves have been developed to add extra functions to the method.

For more information and detailed description of the tool, please visit Overview.


Invert/EE-Lab application

Invert/EE-Lab model was used to simulate the scenarios of development of the building stock and its energy demand in the EU-28 up to 2030/2050/2080 for various scenario assumptions. Different sets of national policy packages on the refurbishment of the existing building stock have been developed in close cooperation with national stakeholders and policy makers. Invert/EE-Lab was applied in more than 35 projects. A selection can be found under projects.

Invert/Opt

The Invert/Opt model is a recent development to add an optimisation model to the Invert model family. It applies a mixed-integer linear programming (MILP) algorithm for finding cost-optimal combinations of renovation and supply options under given constraints.

Invert/Acc

Invert/Acc model is another development for the invert family, which can apply to generate an accounting approach.

Invert/CC

Invert/CC model is the last development that derives energy-saving (and supply) cost curves.
