Digitally Plannable

planbar - the magazine for professional planners, engineers, and architects

More than “just” a magazine: Published twice a year, planbar has, since 2013, evolved into a trusted source of information and an essential reference for planners in the refrigeration, air conditioning, and heating industries.

Each issue features fascinating case studies, important dates, and information on training sessions and events - as well as the “Technology Explained” column and information and planning guides for various systems. In addition, the magazine almost always includes an article on Japanese culture.

In addition to the current issue of planbar, all previously published issues are also available for download here. Enjoy reading!

Issue 2/2026

Dear planbar readers,

Today more than ever, planning means thinking ahead, building connections, and taking responsibility. Increasing demands for energy efficiency, regulatory frameworks, and pressure on urban spaces present daily challenges for planners while also opening up new design opportunities.

In this issue of planbar, we’ll show you how innovative concepts and technical solutions actively support this change. Our reference report on our logistics center in Bottrop illustrates how ambitious energy goals can be achieved in a cost-effective and sustainable manner in large-scale projects. In this sector in particular, it becomes clear that efficiency is not just a goal, but a decisive competitive factor.

Existing buildings also offer enormous potential: The attic conversion project in Dinslaken, which incorporates air-to-air heat pumps, illustrates how urgently needed living space can be created with relatively minimal disruption and high system efficiency.
In addition, we take a closer look at the energy-efficient renovation of several apartment buildings in Cologne-Chorweiler, a project that impressively demonstrates how technology and architecture can go hand in hand. Another example of innovative energy generation in urban areas is a resource that has often been underestimated: heat from wastewater. In this interview, our experts discuss the possibilities.

With the new YXM generation of the City Multi series featuring R32, we also take a look at product innovations that bring even greater flexibility to planning processes - more compact, more powerful, and more adaptable than ever. This issue is rounded out with FAQs on F-gases, which provide guidance in an increasingly complex regulatory environment.

Our goal remains to support you in your daily work - with in-depth insights, relevant projects, and solutions that are consistently geared toward the future of construction.

We hope you find this an inspiring read.
