Energy Efficiency

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 opens up saving potential

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.

Statutory Requirements

The European Union has recognized 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.

Savings through building automation

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.
