POLAND 7R paves the way to trigeneration
Green projectsAdvanced systems are to be developed in the new centre designed to increase the functionality of shock absorbers. 7R has prepared the 11,000 sqm of laboratory and office space to be energy self-sufficient using an advanced trigeneration system. The general contractor for the project was Bremer.
BWI Group has doubled the staff numbers in the company’s technical centre in Kraków over the last ten years and now needs more operational space. Almost 400 engineers specialising in research, design and production processes for car suspensions are to be employed in the new centre.
For a number of years, we have been cooperating extensively with international clients in Kraków. When choosing the location for our new headquarters, we were guided by the fact that we wanted it to be a showcase for our company. The priority was to find a suitable building in a prestigious area, which was in easy reach of both the city and the airport. We are part of the automotive sector, which also imposes on us a responsibility for the environment. All these conditions were met by 7R's offer. We believe that the enormous amount of work put into ensuring that the building meets the highest quality criteria and is environmentally friendly will translate into the well-being and comfort of our staff. We also want the BWI Group centre to be an important and recognisable part of Balice’s commercial landscape.

The high-tech trigeneration system allows gas turbines to generate the energy needed to power, heat, cool and ventilate the building. Gas is used for the staff canteen and directed to the trigeneration unit where the gas turbine produces electricity. The heat generated by the engine and the hot exhaust gas is used in two ways: heating water for the facility and heating the building itself. Secondly, in the summer, when the heat is not fully utilised, heated water is directed to an absorption unit where its energy is used to produce cold water.
We are talking about the unique innovation of the trigeneration system in the BWI Group’s facility, because this is the first time that we have applied it in a commercial office and laboratory building in Poland. So far, such systems have been implemented in waste incineration plants and large industrial plants. In the facility, we have used high-sampling automation, with any excess power being fed back into the local power grid.

The building also has its own well and manages water efficiently throughout the premises.
We have built a water treatment plant from a well that was drilled. Rainwater it is distributed throughout the site. There are five seepage wells under the retention tank where the soil absorbing the water. We have also created a green patio with direct access from the canteen.

The BWI Group plans to introduce the Dali system on its new premises to provide automatic light intensity adaptation, as well as the BMS system. The building is being prepared for a BREEAM ‘Very Good’ certificate.
