Our take
Research by the European Commission suggests that real estate is responsible for 35% of emissions and 40% of energy consumption, a figure only set to grow as countries scale their building projects in line with population increases. These figures mean that to achieve carbon neutrality goals, a rapidly growing number of buildings must be renovated over the next few decades.
Founded by members of the APX accelerator by Axel Springer and Porsche, Purpose Green utilises its founders' rich knowledge about the real estate market to decarbonise the real estate sector. Purpose Green compiles data overviews concerning a building’s energy-related construction and renovation requirements through 3D digital twins of properties. These provide a 360-degree overview of a property's energy status and the work needed to elevate its sustainability.
Working with both real estate portfolios and individual property owners, Purpose Green is currently focused on the German market, its 2024 seed funding allowing it to expand its presence there. Time will tell if the company can expand across the continent, but its steady growth and high-demand market mean it has made a promising start.
