The ADR classification of dangerous goods describes an international system for classifying dangerous goods transported by road, with the aim of identifying risks and implementing appropriate safety measures. …

Classification of waste that remains as residues following incineration (in a thermal treatment plant), in particular slag or ash.

A non-governmental organisation that establishes and administers technical standards for the construction and operation of ships and offshore installations.

The aim of adapting to global warming is to adjust to both climate changes that have already occurred and those expected in the future in such a way that potential damage can be largely avoided and emerging…

The climate as an object of protection refers to the preservation and stability of the global climate. This object of protection also refers to the climatic conditions in a specific region or at a specific…

The aim of climate impact assessment is to examine the regional effects of climate change and, on that basis, to develop appropriate measures for various sectors such as forestry, urban planning and water…

A climate model is a computer-based model used to calculate and predict the climate over a specific period of time. It is usually based on a meteorological model, such as those used for numerical weather prediction.…

Climate protection refers to all organisational, technical and other measures aimed at limiting man-made global warming and preventing, or at least mitigating, its potential consequences (mitigation). …

Determination of the acoustic properties and homogeneity of road surfaces through direct measurement of tyre-road noise in moving traffic using a measurement trailer. 

Static brightness variations in televisions caused by uneven backlighting.

European regulation on the classification, labelling and packaging of chemical substances and mixtures, aimed at communicating the associated hazards clearly and transparently in order to enhance the safety of…

The range of colours that can be displayed by a screen (e.g. sRGB, Adobe RGB, DCI-P3).

The colour rendering index Ra indicates how naturally an artificial light source renders colours. It depends on the spectral composition of the light.

Defines the range of colours that can be used.

On behalf of our clients, we compare the emissions caused by their plants at an international level.

A test in which several products are compared with one another to highlight their advantages and disadvantages.

A pressure wave, compression wave or density wave or contraction wave is a longitudinal wave in a fluid or solid. Transient fluctuations in pressure within a medium propagate as a wavefront. A fluctuation in…

Development of measurement concepts for monitoring construction sites during the building process, including noise monitoring via continuous measurements, observed short-term measurements or quarterly forecasts…

Construction noise is caused at construction sites by the construction or demolition of civil engineering structures. In Germany, noise from construction sites is assessed in accordance with the AVV Baulärm…

An expert assessment of construction noise based on the construction schedule and equipment lists, comparable construction sites, generalised analyses or empirical data.

Vibration emissions caused by construction site operations affecting neighbouring buildings, people or equipment/machinery inside buildings.

A technical device or measure designed to contain substances that pose a risk to water in the event of a spill or leak, and to prevent them from entering water bodies or the ground.

Recording and identifying building materials and furnishings suspected of containing contaminants.

Long-term acoustic measurements to determine noise emissions, e.g. to assess existing noise levels, monitor construction noise, and provide acoustic documentation and analysis in response to complaints from…

Vibrations occurring frequently enough to potentially cause material fatigue, and whose timing and duration are such as to cause a significant amplification of vibrations in the affected structure due to resonance…

Contrast describes the difference between the lightest and darkest areas of an image.

It is often necessary to represent objects geometrically in a different form; for example, LoD2 data can be converted to LoD1 data, or elevation points can be converted to contour lines.

A crematorium – also known as a ‘Feuerhalle’ in Austria – is a place of burial where the deceased are laid to rest not by burial but by cremation. This process is known as cremation; the term ‘incineration’ is also…

The “critical load” is a concept used in environmental science to determine the maximum amount of a pollutant that a particular ecosystem can absorb without suffering harmful effects. It is an important indicator of…

Cultural heritage refers in particular to the physical manifestations of culture in the landscape and to architectural and archaeological monuments. Other tangible assets include, for example, structures that are of…

The umbrella term ‘curve noise’ refers to all types of noise that may be generated by rail vehicles when travelling along a curved track. The main types of curve noises are curve screeching or squealing, as well as…

Curve screeching or curve squealing occurs when rail vehicles travel along tight track curves. This causes the wheels to slip sideways in a jerky manner (the slip-stick effect), which excites the wheels into strong…
