Overview

• Germany’s largest landlord launched a partnership with Enercube and DFA to build the units in Aachen, with series production running through 2029.
• Thirty installations are slated to be in operation by the end of 2025 following a pilot phase.
• Each cube occupies roughly a parking space, integrates soundproofing, and can heat between 10 and 40 apartments.
• The systems are designed to run on solar power from building rooftops, with the companies pointing to lower operating costs for tenants.
• A pilot in Donauwörth reported about 40% energy-cost savings, and North Rhine-Westphalia’s economics minister praised the plan as a strong boost to the heat transition.
