Pollution in the working area – what you need to know.

August 6, 2018
Pollution in the working area depends on the air flow concept as well as the type, arrangement and magnitude of the heat loads; beyond that, it depends on the type and arrangement of the air outlets. For example, pollution levels up to 100% with mixed ventilation can be reduced to below 10% using alternative air flow patterns.

Comfort ventilation: hype or necessity?

April 13, 2018
Hardly any new building can do without controlled ventilation. Due to new buildings being so well insulated for energy reasons, there is no spontaneous exchange of air. So what about old buildings? Does it make sense for them too?

Who and what causes mildew, and how can you prevent it?

February 10, 2018
It's a common misconception that mildew only occurs in old buildings. Where there is moisture, the furry fungus can sprout. Are the inhabitants to blame for not airing out the building enough? Architects who plan incorrectly? Or negligent contractors?

Taking control of IAQ

April 11, 2017
There is growing concern in the UK about the levels of air pollution in our cities and the possible implications for health, but what many people don’t realise is that the pollution inside our buildings can be as much as 100% worse than outside air. How can we fix this?

How important is good Indoor Air Quality?

February 27, 2017
We spend more than 80% of our time indoors, and take 15,000-20,000 breaths per day. So it may come as a surprise to you that the pollution indoors could be up to 100 times worse than outdoor pollution. The air in our homes, offices and schools has a huge impact on our health, so it is...

Ventilation systems for Warehouses: should you go natural or mechanical?

February 15, 2017
Climate technology in a warehouse has to be able to provide supply air and dissipate heat loads and/or pollutant loads. In principle, air flows can be transferred in two ways: either mechanically by ventilation and air-conditioning units or without machines by means of free (natural) ventilation using pressure differences. These pressure differences are created inside the warehouse by heat released during the production processes (negative pressure) and outside by wind pressure.

Smart heating for offices which pays off, with reduction of costs by up to 30%

January 30, 2017
The investor's and developer's goal at the beginning of every project is quite obvious: To build or renovate the building using modern technologies. Execution costs often play a huge role in the decision-making process. However, this innocent idea does not always lead to the expected savings. One such project is the redevelopment of the historic building in the center of Prague.

What is BIM? - and what are the advantages for a HVAC planner?

December 14, 2016
Access to information, priority setting and proper communication between industries are of key importance for the success of designing systems. We currently have files at our disposal, which can be used in 3D modeling of these buildings and building systems. This will enhance the design process and ensure a constant flow of information between all the participants of the process. And that is what BIM (Building Information Modeling) is all about.
