Building Renovation Towards Climate Neutrality

Zerotude is developing an innovative digital service that significantly simplifies the renovation process by proposing optimal renovation measures for residential buildings. Just by entering the building’s address a digital tool carries out energy and climate impact analyses for that specific building, which would otherwise require extensive calculations and on-site inspections from energy experts.

The tool is based on several years of research at LTH and combines artificial intelligence, automation, and open-access databases to automatically generate a 3D building energy model. Multi-objective algorithms are used to propose optimal energy renovation solutions with high accuracy at a fraction of current costs (Figure 1).

This supports building owners during the ongoing energy crisis in upgrading their properties in a cost-effective and environmentally friendly manner. Municipalities can use the service to develop roadmaps for carbon neutrality of cities.
