Vision and Mission

Politicians “design” our outdoor climate by allowing further CO₂ emissions, thereby enabling the Earth to continue heating up.

The Climate Design Days method uses the hourly measured climate data provided by meteorologists to design the extreme winter and summer days as well as the typical monthly days. Meteorologists have prepared the climate data both for today and for the future under the influence of climate change.

We planners design the indoor climate of buildings and rooms, taking into account the outdoor climate as an important boundary condition.

The Building Design Days + Energy (BDD+E) method calculates, based on the hourly Climate Design Days, static balances for each hour of the year for rooms, aggregated to the building level, in order to size the room terminal units for heating and cooling as well as the air-handling systems with heating and cooling coils. Finally, the energy concept components are calculated, which provide the required heating, cooling, and electricity from the available energy sources. By considering all 8,760 hours of the year, the issue of part-load operation becomes visible and can be addressed through sustainable and reliable system sizing.
