<p>At <strong>VREY</strong>, we are building the <strong>EnergyOS for apartment buildings</strong>.</p><p> </p><p>Germany has more than <strong>3.3 million multi-family buildings</strong> - and they are still the blind spot of the energy transition. Less than 1% solar penetration. Less than 2% smart metering. Hardly any flexibility or intelligent energy management.</p><p>At the same time, regulation is forcing property owners to invest: solar is becoming mandatory, smart meters will be rolled out at scale over the next few years, and heating and mobility are becoming electric. Apartment buildings are turning from passive real estate assets into active nodes of the decentralized energy infrastructure.</p><p>What is missing is an integrated system that makes this transition economically attractive and operationally scalable.</p><p><strong>VREY combines certified metering operations with proprietary software</strong> and enables property owners to sell self-generated solar power directly to their tenants. In a simple, digital way, without the obligation to become full energy suppliers under §42 EnWG.</p><p>This turns regulatory pressure into a profitable and predictable opportunity:</p><ul><li><p><strong>Double-digit returns and increased asset value for property owners</strong></p></li><li><p><strong>~20% electricity cost savings for tenants</strong></p></li><li><p><strong>Digital infrastructure for batteries, heat pumps, EV charging and flexibility</strong></p></li></ul><p>Today, we already support a triple-digit number of projects - including leading real estate owners and housing cooperatives - across all 16 German federal states. After a very short time in the market, we are already among the leading providers in this category.</p><p>We are at the beginning of a structural market shift. Whoever defines the energy infrastructure of apartment buildings today will shape it for decades. Join VREY and help us build the leading EnergyOS for apartment buildings.</p>
