Monitoring of Environment and Structure

Good climate data are critical in the design of permafrost infrastructure. They form the basis for calibration work before any construction starts and they are important input data when assessing the reliability and performance in the future. Therefore a climate station that measures air temperatures, precipitation, snow depth, short wave and long wave radiation, and wind speed and direction, is to be installed as early as possible. Often there is an existing network of weather stations that can be utilised to determine the locally prevailing conditions (in particular air temperature and snow depth).

Reference measurements should be carried out at a certain distance from the structures. By comparing reference measurements (e.g., ground temperatures, deformations) with the data recorded within or close to the structure, various influences, e.g. due to climate change, can be analysed individually. By analysing such factors separately, better adaptation solutions can be designed in the future. The responsibilities of data analysis and management should be clearly determined and alarm values and reaction scenarios must be defined in advance.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
