Can an existing CAV system be upgraded to VAV?
Only a very small proportion of the building stock increases annually from newbuilds. The majority of the building stock is made up of existing premises, many of which are currently energy-inefficient. In 30 years’ time, a large proportion of these buildings will still be standing, which means that …Andreas Örje Wellstam
Taking on the climate challenge – a New York City perspective
The climate discussion often tends to be very much focused on topics such as transportation and food production. And rightly so, these are important areas, but we also know that about 40% of the energy consumption world-wide is related to our buildings. So what better place to get a grasp of this …Timo Schreck
Relative humidity in the indoor air – impact on indoor air quality
Indoor air humidity is often associated with various problems and high operating and service costs. Humidity control is often related to removing moisture from the building, not controlling it. In some specific applications, it is necessary to maintain the humidity at a certain level defined by …Elvis Kokot
System solutions deliver better results
Requirements for energy efficiency and smart solutions make present-day and future construction projects more complicated, and it is becoming increasingly important that all property systems can communicate with one another. An easier way to ensure a smooth and efficient final installation is to …William Lawrance
How to increase energy-efficiency of your air handling unit
As Google searches regarding energy-savings have somewhat skyrocketed lately, it is reasonable to think that the following search has been made more than just a few times: how to save energy + AHU?Alberto Ferrandi
What you need to know before selecting a heat pump
Just a few years ago, chillers totally dominated the market, while the number of heat pumps sold and installed was low. Today, EU demands, new technology and focus on decreasing fossil fuel dependency has made the market for heat pumps explode. The need for getting rid of gas boilers has opened up …Andreas Örje Wellstam
Two reasons HVAC and gender equality needs to be a top priority
In the heating, ventilation and air conditioning (HVAC) industry – and the building sector in general – men are still in a vast majority. And although I wish it looked different, Swegon is no exception. I know we can do better, and I firmly believe a more equal organization will be a more …Timo Schreck
Clearing up a few myths in humidity recovery
There are many assumptions and opinions circulating around humidity recovery in the European HVAC industry and among HVAC engineers. Some of them are based on bad experiences, some of studies or claims presented with a certain partiality. I will try to clarify some these myths based on my …By topics
