Rome's "Via Laurentina" awarded gold medal for sustainability

The "Via Laurentina" is the first building in Italy to be awarded the Gold LEED Green Building certificate. Owner: SEB Asset Management.

The LEED Green Building certificate documents the building's ecological sustainability, high user comfort and low operating costs. Drees & Sommer supported the project from the first analysis through monitoring to certification.

The Via Laurentina is the first building in Italy to be awarded the Gold LEED certificate in accordance with NC 2009. Drinking water consumption was reduced by nearly 80 percent and energy consumption by nearly 40 percent. The building has renewable energy systems that cover some 18 percent of the building's energy demand. 93 percent of removed material was recycled. Since August 2009, SEB Asset Management and Drees & Sommer have been working on certification of the office building.

SEB Asset Management purchased the building complex eight years ago for its open-ended real estate investment fund SEB ImmoInvest. Even at the time of purchase in 2003, it was intended to completely refurbish the five buildings in close cooperation with the tenant, an Italian energy and oil company. "The challenge lay in undertaking the building work without impacting the tenant. As the result of close cooperation with the tenant, we were able to exceed the original specifications, with the result that the lease has been extended by nine plus six years says Axel Kraus, the Managing Director of SEB Asset Management responsible for property management.

Initially, the intention was to apply for LEED Silver certification. Thanks to close project support, Gold certification was achieved for the first of the five buildings within budget. The team is now striving to achieve Gold for the remaining four buildings in the complex. Gold LEED certification for the Via Laurentina shows that greater sustainability and energy efficiency are achievable for established buildings says Christian Motter, Drees & Sommer Project Partner in Milan.

The specialists examined numerous processes within the building, such as material flows, including the use of office materials and waste disposal. Detailed knowledge and years of experience in the area of Green Buildings and in high-rise and established office buildings were essential prerequisites. Energy demand was monitored with state-of-the-art tools to ensure the best possible optimization outcomes. The expert team carried out an energy analysis of the office buildings with a total floor area of 48,000 m² built between 1978 and 1982 and developed appropriate optimization proposals.
