Space requirements for heat pump solutions
The European Renovation Wave is under way, meaning a large number of older heating and cooling units are currently being replaced with modern heat pump solutions with lower climate impact. However, before a unit is replaced there is an important aspect to consider – the available space for a new …Caroline Jacobsson
Can profitable also be sustainable?
Two years ago, we published a blog post which discussed whether a demand controlled indoor climate is a profitable investment. I was recently asked to return and, with a couple of years' perspective, comment on whether the topic is still relevant or if any changes have occurred that affect the …Alessandro Pinato
Energy savings from an HVAC orchestra
Energy efficiency in buildings is more important than ever. To optimize the efficiency of a solution for ventilation, heating and cooling (HVAC) and also maintain high comfort levels, considerations can not only be made to the efficiency of individual units, they all need to work together.Carl-Ola Danielsson
Active chilled beams with variable k-factor - an option for both CAV and VAV systems
To create a healthy and comfortable indoor environment where people can perform an thrive, it is important to ensure good air quality. This, without creating noise and without causing discomfort due to high air velocities, temperature gradients or radiant asymmetry. The challenge is to design a …Martin Ottersten
Can inaudible noise be harmful?
Imagine you enter a building and, almost immediately, feel an indescribable discomfort. You listen and hear no noise, you breathe and find the air quality good. When you leave the building the previously felt discomfort disappears. Can the building have caused this distress? Unfortunately, yes. …François Jouvray
The BACS decree: good is not going to be enough
It is September 2023, less than two years remain until the middle of 2025 – a significant checkpoint for numerous countries, regions and organisations in their pursuit to reach various sustainability targets. Beyond this year, countless check points for both completed actions as well as …Malin Höij
Continuous improvements and standardisation - interview with Johan Lundgren
Significant improvements and genuine contributions for better tomorrow can be achieved when products and production processes are known in every detail. That is what Johan Lundgren, Plant Manager at the Swegon factory in Tomelilla, believes and he has enthusiastically told me about the many …Andreas Kihlström
How is ventilation, heating and cooling related to the EU Renovation Wave?
Most of us have heard about the European Green Deal and the EU Renovation Wave, the latter in particular is well known in our industry of ventilation, heating and cooling (HVAC). But why have the European Union launched this initiative, what are the goals and what does it mean to us?Robert Siverby
Recycled steel lowers the carbon footprint
The building sector produces a significant part of the global emissions today. An important step on the road to sustainable practices is to lower the footprint from embodied carbon in products.By topics
