3 Passive House Ventilation Modes to Provide Occupant Comfort
Buildings designed to meet Passive House criteria are known primarily for very low energy consumption. Occupant comfort, however, has always been one of the stated goals of the Passive House. According to Passipedia, a Passive House Institute (PHI) resource, Passive House is “a building standard …Mike Woolsey

How to manage leakage rates with rotary air to air heat exchangers
Fact is, all plate, rotary and heat pipe air to air energy recovery devices leak – but it is a very small amount compared to the overall air movement in a building. Swegon uses all forms of energy recovery devices including plates in GOLD PX, Rotors in GOLD RX and heat pipes as secondary recovery …Åsa Norén-Lundh
Things to consider when choosing room units for variable air flows
There are a few things to consider when choosing room units for variable air flow to save energy and to achieve a comfortable indoor climate. In this article, we will walk you through the most important ones.William Lawrance
Getting to grips with internal leakage in air handling units
Internal leakage of air in ventilation systems is wasteful and it can also affect the indoor air quality so we need to minimise leakage to both optimise the energy consumption and ensure the best possible air quality. In this article, you will get to know different modes of internal leakages and …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 …William Lawrance
Commissioning air handling units is all about the work off site
The commissioning and adjustment of air handling units can be time consuming, and due to the human factor, the units are not always set-up as intended, resulting in inefficient operation. But this may soon be history, the tools to streamline the whole process are already here. And the trend is …By topics
