Nearly 150 solar panels with a total capacity of 81.76 kWp have been installed on the roof of phase one of the Budapest ONE office building. The green energy generated by the system—roughly the size of two volleyball courts—further reduces the building’s emissions while also lowering energy costs for its tenants.
The 146 solar panels collectively generate 80,000 kWh of energy annually, reducing the building’s carbon dioxide equivalent emissions by nearly 18 tons each year. The multi-million-forint investment was fully financed by the project’s developer and operator, Futureal. As a result of the installation, Budapest ONE’s energy performance certificate rating has improved from CC to BB. The green energy generated by the system could result in annual savings of several million forints, which will proportionally reduce tenants’ energy costs.
“From the very beginning, our goal with Budapest ONE was to create a human-centred, sustainable building that meets even the most demanding expectations of our tenants,” said Gábor Radványi, Chief Architect and Head of Sustainability at Futureal. “We are committed to continuous maintenance and upgrades using cutting-edge solutions. This dedication is reflected in the trust we’ve earned from numerous prestigious tenants, including ORACLE and British Telecom’s regional service centre.”
Located in Őrmező, Hungary’s largest transport hub, the 66,000 sqm Budapest ONE complex was developed by Futureal with a strong focus on accessibility and well-being. The building has earned Gold certification from Access4You for its outstanding accessibility and meets the strict Platinum rating of the WELL Building Standard, which evaluates factors that positively impact employee health and well-being. In addition, the entire development has achieved the BREEAM Excellent certification, one of the highest global sustainability ratings for buildings. Designed to withstand extreme weather conditions and climate change, the complex incorporates the highest technical standards. It features a smart central building management system and a heat recovery ventilation system for maximum energy efficiency.
Inside, calming colour schemes create a peaceful atmosphere, complemented by a dedicated WELL-room, a spacious green rooftop garden, secure bike storage with showers, and a 500-meter, 360-degree panoramic rooftop running track with a rubber surface. The building also provides charging stations for electric cars, bicycles, and scooters, as well as selective waste collection points. A unique, half-hectare open community space with landscaped greenery and a stage fosters social interaction and serves as a popular meeting point within the building.
