Economically and ecologically essential Energy savings in the double-figure percentage range

Optimisation of energy efficiency in buildings means for us

  • Only use energy when it is really required

  • Only use the amount of energy actually required

  • Apply the energy that is used with the highest possible efficiency

Climate change and growing shortages of resources are the big challenges of our time. In addition, many countries around the world are dependent on imported energy – in the EU, for example, 50 % of energy consumed today is imported – a figure expected to reach 70 % by 2030. Efficient and sustainable energy usage is therefore an urgent necessity – fully in accordance with the motto coined by the European Commission “less is more”.

Following the areas of transport and power generation, building technology is the largest consumer of energy. Heating, cooling and lighting in residential and office buildings make up approximately 40 % of the energy consumed in the industrial nations – a share that leaves a lot of scope for efficient optimization.

On the European level, this fact has been met with the publication of a directive relating to the energy performance of buildings (2002/91/EC). The main demand that it incorporates is the issue of an energy certificate detailing the energy consumption of the building as well as analysis of the potential savings. To pave the way for these measures, a number of European Standards have been implemented – e.g. EN 15232 – and in Germany a DIN standard (DIN V 18599) confronts the issue.

The central role of intelligent building control Building system engineering supported by intelligent and networked room and building controllers (lighting, sun protection, heating, ventilation and air conditioning as well as the other building engineering systems) contribute significantly to conservative and requirement-based energy use. The worldwide standard for KNX technology enables energy savings in the double-figure percentage range and also provides enhanced flexibility with planning and implementation, a high level of investment protection and a high level of availability.

Various concepts and approaches are possible in the optimisation of energy efficiency in buildings. In this context, the use of intelligent building control provides a proven and interesting alternative or addition that is clearly set apart by its convincing cost-benefit ratio.

In this brochure, you will find figures, data and facts, which clearly indicate the high level of optimisation potential offered by using ABB i-bus® KNX intelligent building control.
