Around 40 percent of global primary energy consumption can be attributed to buildings. Buildings are thus among the largest energy consumers. A particularly large share of that energy is attributed to non-residential buildings– about two-thirds. Improving the energy efficiency of buildings both saves energy and reduces CO2- emissions.

Building automation creates especially high savings potential- both in new buildings and in the renovation of existing buildings. Building automation not only saves energy but also thermal power such as lighting or air conditioning – sustainably and over the entire lifecycle. Building automation can halve the primary energy demand of a building.

The necessary investments are relatively low compared to expensive insulation measures and facility renovations. Return on investment through savings in energy costs is very fast. In a few years, investments in building automation are expected to grow.

The European Union has recognises the high potential for energy savings in buildings and has adopted policies to improve the energy performance of buildings (Energy Performance of Buildings Directive EPBD). European countries will implement this in national laws and regulations.

In Germany the EPBD is implemented by the Energy Saving Ordinance (Energieeinsparverordnung — EnEV). The EnEV labels buildings with an energy certificate. This divides each building into one of four different classes based on its energy consumption or energy needs.

The European Standardisation Committee CEN TC 247 has developed a methodology based on the EPBD to clarify the effects of building automation on the energy performance of a building. Buildings are divided into four efficiency classes depending on the degree and the quality of their equipment.

The benchmark is set at building Class C. These are equipped with a standard building automation system. This includes, for example, occupancy arrangements with a time program. Worse than class C is class D with non-efficient building automation. The classes B and A, on the other hand, are for buildings with advanced or highly efficient building automation systems.

The table below shows the savings potential of different types of buildings of class A over their Class C counterparts:

Offices 30% savings
Lecture theaters 50% savings
Schools 20% savings
Hospitals 14% savings
Hotels 32% savings
Restaurants 32% savings
Kieback & Peter helps to improve the energy quality of buildings to increase energy efficiency, save energy and money and to protect the environment sustainably.

Energy efficiency plays a double role in in building automation products. First is the contribution of products to improve energy efficiency. Important keywords in this context are control quality and control accuracy. Second is their own energy consumption.

The small actuator used in the room and zone temperature MD15, for example, achieved characteristic high control quality via a pronounced valve. With a power consumption of less than 2W its own power consumption is also very low.

The single room controller from the RCN technolon® range was even eu.bac certifed as one of the first individual room controllers. The eubac-certification confirms the highest control accuracy and compliance with European directives for energy efficiency.
