Specifying VAV Dampers: A Practical Checklist | Part two – The Decision Process
VAV dampers need to communicate with the wider control system. This may be through a simple analogue signal or through a digital protocol, depending on the building strategy.Specifying VAV Dampers: A Practical Checklist | Part one – Getting to know your VAV’s
Variable Air Volume systems are often associated with energy efficiency, comfort and demand-controlled ventilation, but the performance of any VAV system depends heavily on the correct damper specification. A VAV damper is not just a component in the ductwork. It is responsible for measuring, …Why the casing of air handling units is critical for a healthy indoor climate
To achieve a good indoor climate with low operating cost, the ventilation solution must be designed and installed in a proper way so that energy losses are minimised and air quality preserved. This means that it must be airtight and well insulated but also be formed to allow cleaning. Something …Why you should eliminate all monotonous noise in your building
Sound can be a source of pleasure and well-being, if it is the right kind, like beautiful music. But research has found that the wrong kind of sound, or noise, is also a major cause of health problems. According to the World Health Organization, western Europeans are losing millions of years of …Circularity: From pilots to industrial scale
In previous blog posts (links below), it has been highlighted why embodied carbon requires more attention and how circularity is increasingly becoming part of the sustainability efforts in HVAC and the building industry. Through the Nordic Circularity Piloting Program, we have tested circular flows …There is more to your indoor climate system than climate control
Most professionals in the building industry know, and can mention, various smart and reliable systems for demand controlled ventilation (DCV). These systems feature a set of functionalities, all aimed at keeping the indoor climate healthy and comfortable. Most of these systems measure temperature, …Things to consider when choosing an AHU for small premises
When choosing an air handling unit (AHU) for smaller premises, such as retail areas in an otherwise residential building, there may not be an assigned technical room, and the premises may be on the ground level. This will put some special requirements on the ventilation solution. In this article, …Zero-emission buildings (ZEB) – utopia or feasible?
The concept of zero-emission buildings (ZEB) has for a long time fluctuated between being a vision and becoming a reality. For some, it is a necessary standard for the future, for others an idealistic goal far away in time. As climate requirements tighten and new regulations spread across Europe, …The Benefits of Selection Tools
In this blog post, we look at how Andy Dines, Digital Product Developer, has helped to shape the way we use selection and scheduling software.Chilled beams re-invented: Maintaining performance in a world of variable airflow
For decades, one of the strongest selling points of chilled beams has been their simplicity. With no fans, no drainage pumps and no mechanical moving parts, chilled beams have built a reputation of being reliable, low in maintenance and offer a long product life. This passive design has made them a …By topics
