Climate-neutral district thanks to smart ventilation

Europe's first climate-neutral city quarter is being built in Ludwigsburg. The Maier family is turning the digital dial and organizing sustainability via the cloud. How the vision is becoming reality thanks to smart ventilation.

An anchor for sustainability

The 200,000 square meter urbanharbor in Ludwigsburg provides a dedicated ecosystem comprising startups from around the region, restaurants, retail and entertainment venues. The vision behind it is to be the first productive urban quarter in Europe to operate on a climate-neutral basis by 2030.

“Sustainability is my motivation.”

Max Maier, owner of Max Maier Urban Development, talks about his vision

Ventilation from house to house

The factory halls used to make fridges and the like; now startups from around the region are working on ideas for the future in its state-of-the-art office facilities. The energy concept: The ventilation system only conveys fresh air between the office and hall roof at the locations where the staff actually are.

Air where it’s needed

Christoph Hornek, responsible for the ventilation and building services technology, opted to try a new approach: A semi-centralized ventilation system with some 300 local precision controlled ebm-papst fans, incorporating the Cloud-based Building Connect platform from ebm-papst neo as the brain behind the demand-based control system.

“Air is not wasted.”

Christoph Hornek, CEO of i-on Engineering GmbH, about his approach

The brain behind the ventilation

ebm-papst neo developed the Building Connect platform for just such an application. It uses sensor data to analyze the air quality and manages the ebm-papst precision-controlled local fans accordingly. The site layout is permanently viewable on any mobile device.

“The staff in the offices feels better.”

The data path

The sensors measure the temperature, humidity, levels of TVOC (organic substances) and fine dust and the CO2 content in the air. The data is sent to the ebm-papst Cloud, where it is processed and transmitted to the fans as the basis for controlling the ventilation system. They increase their air performance when levels rise above 900 ppm until the value is back in the ideal range.

Vision has become reality

Demand-based control reduces the amount of air needing to be conditioned by around 50 percent, and cuts down the electricity required to convey the air by 30 percent. Max Maier assumes that in Hall 8 in the worst case it will overcompensate by 63 to 250 tons more CO2 in addition to achieving climate neutrality.

“A platform where people can be inspired.”
