Room Air

Indoor air is so important simply because it affects us all. The quality of indoor air is regulated in DIN EN 16798-3. The desired indoor air quality is graded in four indoor air stages, ranging from IDA 1 (high quality) to IDA 4 (low quality).
The desired quality depends, among other things, on the Outdoor-Air value, which is defined in three stages from ODA 1 (clean air) to ODA 3 (high dust concentration in the outside air).

Heating, ventilation, and air conditioning/Air Handling Units

The task of a HVAC system is to generate and maintain a certain indoor air quality. The ODA value must be taken into account when planning air conditioning systems. A database exists for relevant air measurement data, which enables the specialist planner for ventilation and air-conditioning systems to easily obtain an ODA value for an exact building location.

Air quality is essential for the comfortable use of buildings. There are – depending on the building – official requirements to be met in this respect. Fresh air conditioning includes the regulation of temperature, humidity and cleanliness, which is achieved by heating or cooling, drying or humidifying, filtering or exchanging room air.

Data Centre

The operation of data centres or server farms, i.e. the concentrated accumulation of IT storage technology, is all about efficient cooling on the one hand, and the best possible protection of hardware against corrosion by fine dust particles such as sulphur dioxides or nitrogen oxides on the other.

The smallest office in the world …

In London, the red telephone booths are being converted into 1-square-meter offices by a company and rented out. The first mini-office has opened in Russel Square. The rent for the office is 25 pounds per month and can be managed via an app.
