The sustainable and resource-efficient planning of the heylo in the Düsseldorf district of Golzheim points the way to a future that combines the highest ecological and economic standards.

The building was already familiar to ZWP Ingenieur-AG: around the turn of the millennium, it had planned the technical building services for the office property, which was still called Spherion at the time and was inaugurated in 2003. A good 20 years later, the ESG-compliant renovation of the existing building on Schwannstraße is on the agenda. The goal: a sustainable multi-tenant building—and MorgenGrün is on board with ZWP.

Renovating the existing building in line with ESG while keeping costs and effort under control was a major challenge: the aim was to improve what needed improving and maintain what was good.

Setting the course for a sustainable future

Our dedicated MorgenGrün team advised HPP Architekten GmbH from the initial feasibility studies phase onwards. This enabled us to significantly improve the acoustic and thermal comfort for future users. The thermal comfort in the atrium and in the adjacent rooms has increased considerably thanks to the selected sun protection and ventilation measures. Converting the building to “All Electric” via the new heat and cooling supply based on heat pumps was another milestone.

heylo smart building: a pioneer in sustainability and resource conservation

Our team checked all aspects of the renovation using the DGNB Pre-Check. The result: the heylo's sustainability performance meets the DGNB Gold Standard.

With the help of extensive simulation calculations—from thermal to flow to daylight simulation—we checked and verified the proposed concepts. The new interior fittings meet today's requirements for workplaces with good room acoustics in terms of speech intelligibility or undisturbed work.

After the renovation, the building will also be up to date around smart building. Modern technologies such as smart lighting and smart parking as well as data connectivity contribute to this. They ensure maximum energy efficiency in building automation while also providing user comfort.

In the future, the heylo will be heated purely electrically—and thus emission-free and, in the long term, almost CO₂-free. We are proud that we, as the energy efficiency experts responsible, were able to obtain extensive KfW fundings for our clients.
