As the first in Poland Katowice’s GOEPPERT-MAYER Office Building has been awarded a prestigious BREEAM International Outstanding certificate. It is the second building in Europe with such high rating. 

BREEAM Certification (BRE Environmental Assessment Method) is the most valued assessment method for buildings in Europe in terms of their ecological features and comfort of the future user which at the same time sets standards for sustainable design. The method was developed by the Building Research Establishment (BRE) in the United Kingdom in 1990.

Each office space investment project that seeks
BREEAM Europe Commercial 2009 certification is assessed in 10 categories:



land use







health and wellbeing

Buildings that have been subjected to multiple assessments are awarded a certificate confirming the extent to which the requirements recognised by BRE as important for the building’s operation in its environment have been incorporated in its construction. The “Outstanding” rating for the Katowice office building is the highest available rating in the BREEAM system. It is difficult to achieve due to the need to use above-standard in almost all categories. Obtained such high marks require fulfilment of over 85% of all certificates ensuring care for the natural environment as well as health and well-being of facility users.

The GOEPPERT-MAYER office building, which has also received awards in many industry competitions, is a pioneer in energy sustainable buildings. An innovative natural gas-powered system (CCHP) was used in the building to simultaneously produce electricity, heat and cold for development. The system used is capable of producing about 1500 MWh of electricity annually, which is enough to cover the building’s demand.

The office buildings also feature a highly-effective heat recovery system, an advanced facade system, heating and cooling beams, central moistening of rooms, charging stations for e-vehicles, fibre optic connections for information technology and communication networks, and many other energy-saving and pro-ecological solutions. Everything is controlled and managed with the use of a modern Building Management System (BMS). Besides the highest class office space, tenants have been provided with a corresponding number of car park places, a modern conference centre, a restaurant, a fitness club, a private kindergarten, and a virtual office.

A multi-year analysis of the building’s performance has confirmed the assumptions that energy consumption in the GOEPPERT-MAYER Office Building is by some 50% lower than in typical class A office buildings while ensuring full comfort for its users. The projected total demand for primary energy in the building, estimated on the basis of the annual period of its operation, is below 111 kWh/m2/year. For the sake of comparison, a figure adopted for a reference building is 185 kWh/m2/year. Primary energy for the building’s heating and ventilation purposes as defined on the basis of its annual period of use, amounts to 28 kWh/m2/year, given that the volume of fresh air in the building has been increased by 75% (36 m3/h/person). In case of the reference building that figure, given the standard volumes of fresh air stands at 73 kWh/m2/year. As a result, the total monthly costs of utilities (heating, cooling, water, electricity, and ventilation) are below PLN 3.50 per 1 sq. m. of rented space, given a one-shift operation mode.

The quality of the development confirmed with a relevant certificate has a direct impact on an increased demand among tenants. Advantages of the office buildings located in the GPP Business Park complex have been spotted not only by large international corporations, such as ING Services Polska, Teleperformance, ABB, or Netia, but also businesses seeking small, but prestigious office space. Almost the entire office space has already been commercialised. GPP Business Park has already constructed three out of the four smart, energy-efficient and sustainable office buildings in the complex. The fourth building shall be named after a Nobel Laureate Konrad Bloch.
