Banu Antonache Offices in Bucharest has received LEED Platinum certification for the operation of an existing building following a programme of technical upgrades and closer monitoring of its energy and resource use.
BuildGreen coordinated the LEED v4.1 Operations and Maintenance certification for the property, which is owned and managed by Adval Asset Management. The office building is located in the Floreasca-Dorobanți area and was completed in 2006, making the certification an example of how older commercial properties can be upgraded rather than replaced as environmental requirements increase.
The property provides 4,472 sqm of lettable office space across the ground floor and five upper levels, together with two underground floors and 79 parking spaces. These basic specifications and the building’s 2006 completion date are also confirmed by Adval’s property information and independent Bucharest office-market listings.
The certification process took around four months and assessed the way the property performs during normal operation rather than focusing primarily on its original design. Twelve months of energy, water and waste information were reviewed, while technical work included indoor air-quality measurements and an ASHRAE energy audit.
Banu Antonache achieved its strongest result for indoor environmental quality, receiving 19 of the 20 available points. It also secured 13 out of 14 points for transportation and 27 out of 33 for energy performance. The Platinum result follows investment by Adval in technical and security systems, operational monitoring and measures intended to improve control over energy and other resources.
Adval plans to continue investing in the building rather than treating the certification as the end of its modernisation programme. The asset manager also intends to pursue periodic recertification, including consideration of the newer LEED v5 framework, and is evaluating additional standards covering occupant health and building operation.
The project reflects a wider challenge for the Bucharest office market as owners consider how to keep established properties competitive while tenants and investors place greater emphasis on operating costs and environmental performance. Other existing Bucharest offices have also recently achieved LEED Platinum after operational improvements, including GTC’s Premium Point and Premium Plaza, demonstrating that certification at the highest level is increasingly being pursued across older office stock as well as new developments.
For existing office owners, this approach can provide an alternative to extensive redevelopment. Banu Antonache shows that a building approaching 20 years of operation can be repositioned through technical investment, performance measurement and active management, extending the useful life of existing real estate while responding to increasingly demanding sustainability requirements.
