The Panattoni Park Kladno South industrial zone has been awarded the highest rating of “Outstanding” under the BREEAM New Construction international sustainability certification. The project, developed jointly by Panattoni and Accolade, includes a new production hall and the renovation of an existing industrial building, totaling over 36,000 square meters. The facility is leased by Hanon Systems Thermal Technology, a manufacturer of automotive cooling systems. The company expanded its operations with the addition of a nearly 21,000 square meter production hall, while the existing 15,500 square meter hall underwent a significant renovation. Both construction phases were completed without interrupting ongoing operations. The project incorporated a range of sustainability-focused measures from early planning through to execution. These included the use of low-carbon materials, a waste management strategy that diverted more than 85% of construction waste from landfills, and energy-efficient building systems. A helicopter was used to deliver some construction components to reduce road traffic impact. Energy performance improvements include a 2,225 kWp photovoltaic installation that now fully powers the facility’s electricity needs. Combined with heat pumps and gas heating, this has resulted in a 54.66% reduction in annual CO₂ emissions, equivalent to more than 3,000 tons. A rainwater harvesting system has also reduced drinking water use for flushing by over 66%. The BREEAM Outstanding rating is achieved by only a small percentage of buildings pursuing certification. According to Accolade, this is the ninth project in its portfolio to reach this level. The site’s location in the Kladno region offers strong infrastructure links and access to a skilled workforce. It is close to the D5, D6, and D7 motorways and near Václav Havel International Airport. The upcoming modernization of the rail connection between Prague, the airport, and Kladno is expected to further enhance the area’s connectivity.
