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. …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 …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.Alberto Ferrandi
Polyvalent units and heat recovery is growing in colder climates
In recent years, heat recovery has become an increasingly more common and desirable functionality in units for ventilation, heating and cooling (HVAC). The general idea is to recover as much as possible of the energy that has already been “spent” for heating or cooling, and use that energy again …Alberto Ferrandi
Heating in one step or two steps?
To do things in one go, sounds so easy. In many cases the results of doing things in one step is equated to doing things in two steps. However, in certain situations or under certain conditions it can be advantageous, and hence preferred, to do things one after the other. A twostep approach can …Alberto Ferrandi
Why you should consider a 4-pipe system for cooling and heating
A traditional two-pipe system for heating and cooling may not be an optimal solution for buildings with mixed usage that combines, for instance, retails, offices and hotels. Besides, the southward side of the building facing the sun might require cooling at the same time that the northward side, in …Steve Gore
NSHEV's: Meeting the Standard for Passive Ventilation
Carrying on with the theme of Smoke Extraction from last year, this month we will look at a slightly different product, a Natural Smoke and Heat Exhaust Ventilator (NSHEV).Martin Brady
Three Common Considerations of HVAC Maintenance
Heating, ventilation, and air conditioning (HVAC) equipment is a crucial component of any building's infrastructure, responsible for providing comfortable indoor conditions for occupants. However, like any mechanical system, HVAC equipment requires regular maintenance to function at its best.Alessandro Lora
Can the most sustainable and cost-efficient source of energy-saving can come from HVAC solutions?
In the UK, buildings make up for approximately 17% of all carbon emissions. Whilst the Energy Performance of Buildings Directive (EPBD) is being revised for countries within the EU, the UK's first Net Zero Carbon Buildings Standard, championed by leading industry organisations including CIBSE and …Alessandro Pinato
Ground source heat pumps – even better with propane
One of the biggest macro-trends with regards to heating in Europe is electrification. During renovations and refurbishments inefficient heaters and aging boilers – which produce CO2-emissions and pollution – are gradually being replaced with more modern solutions, like heat pumps. Now, what if a …By topics
