Bottrop, Germany -- Materials manufacturer Covestro is leading a building modernisation project that has achieved a 75% reduction in energy consumption.
North Rhine-Westphalia’s Bottrop Innovation City contains one of the world’s first office buildings that generates more energy than its occupants consume, said Covestro.
Polyurethane foam, according to Covesetro, is key to the renovation’s energy-efficiency.
As part of the building's opening ceremony, NRW KilmaExpo's senior md Heinrich Dornbusch presented a certificate documenting the building’s official inclusion among the country's major climate protection measures to Joachim Wolff, head of Covestro’s polyurethanes business unit.
Wolff said: “This Building of the Future can serve as a model for the many commercial properties in Germany and throughout the world that have not yet been refurbished for improved energy efficiency.
“There is quite obviously a need for such action. And it is also clear that we can take steps to remedy the situation. After all, with expert refurbishment and the latest building technology, the energy needs of a house can be cut by as much as 80%,” he added.
The initiative’s objective is to pursue numerous individual measures in large areas of Bottrop to reduce CO2 emissions by half and improve quality of life.
In addition, partners from the EcoCommercial Building Program – a Covestro-led international network of experts specialising in sustainable construction – supported the renovation project.
Bottrop’s overall heating energy consumption for 2014, according to the 2015 Techem Energy Services value study, declined by about 24% compared to the previous year.
The office opened on Friday, 16 October, 2015.
