Energy consumption High potential for savings in buildings
Buildings are among the largest energy consumers. Approximately 40 percent of global primary energy consumption is attributed to supplying buildings with heating, cooling and electricity, about two-thirds of it for non-residential buildings. In Germany alone, 75 percent of all non-residential buildings are in need of energy-consumption renovation, according to the study “Efficiency of Public Buildings” by Prof. Dr.-Ing. Rainer Hirschberg of the University of Applied Sciences Aachen (2004). The savings potential in this area is enormous. The study estimates that energy consumption can be reduced by 45 percent. With the consistent utilization of all potential savings alone, a reduction in CO2 emissions by 27 million tons is realistic. With building automation alone approximately one quarter of this savings potential can be realized. Building automation has the advantage that it can be implemented very quickly and can sustainably reduce energy cost. Building automation also has a rapid return on investment.

Energy efficiency Not only a must but full of advantages
In the face of dimishing fossil fuel resources, increase in energy prices, and the threatening impact on the environment, the European Union has passed a directive on the energy performance of buildings (Energy Performance of Buildings Directive, or EPBD). The aim of this directive is to improve the energy efficiency of existing and newly constructed buildings.
On the basis of the EPBD the European Standardization Committee CEN TC247 has developed methods, which clarify the effects of building automation functions on energy efficiency. The committee also determines standards for auto mation components in order to be able to assess their quality in terms of energy efficiency. eu.bac tests devices based on these standards.
The directive is the basis for the German energy saving regulation (EnEV). This stipulates an “energy pass” for all buildings, which are divided into different classifications according to their energy consumption or energy requirements.
Energy efficiency in buildings not only reduces environmental impacts. It also saves operating expenses as well as enhancing the sustainable value and usability of the building. Energy efficient buildings will more likely find future buyers or tenants.

Interview Building Automation is still undervalued Dear Professor Hirschberg, why is the building sector so important in terms of CO2 reduction and the realization of climate protection objectives? With approximately a 41 percent share of primary energy consumption, buildings are the largest cause of CO2 emissions. That is about 50 percent more than the transportation sector’s. What are the strategies for saving energy in buildings? Energy conservation is fundamentally based on three pillars – reduction of demand, increased efficiency and energy management.
Demand reduction always represents a passive use of energy. Demand reduction can also be reached through the design and form of the building shell, as well as by modifying usage requirements. Increased efficiency and energy management, on the other hand, mean active handling of energy. Increased efficiency in plant-specific systems is primarily obtained through practical system solutions. The installation components applied in the process have a supporting influence, but not a dominating one. Additionally, excellent installation components with low energy consumption cannot increase the efficiency of a bad plant. Something that is unfortunately often overlooked is

that the connection of renewable energy sources is possible only in installations which are active and not passive. Energy management is one part of plant operation management, and is highly important in terms of energy consumption. In terms of energy evaluation of buildings and their installation technology, demand reductions and efficiency increases are determined by given use requirements, keeping all considered variables constant. By contrast, automation systems guarantee the adjustment to the actual user behavior and eliminate malfunctions through unintended interactions that go unnoticed by people. The reduction in demand on the building shell encounters appreciable limitations if you also consider the sustainability of the product manufacturing. The equipment efficiency utilizing renewable energy represents a far greater savings potential. The impact of building automation systems on energy consumption is considerable and is unfortunately still all too often undervalued.
What are the special advantages of building automation? With building automation the complex interaction between usage, building shell, and plant systems are consistently controlled and regulated. People are simply overwhelmed by the complex relationships – it is, after all, a question of dynamic systems – to be able to consistently give the correct instructions. It is about time that the use of automation systems – one could also say assistance systems – becomes a matter of course, just as technical equipment and systems in other fields have as well. What are the requirements allowing users of building automation to tap its full potential? For starters, installation systems must be equipped with considerably more sensors, so that even better monitoring of the current operating status becomes possible. Moreover, the cross-functional connection of all installation systems to a complete system of plant management is also necessary. The constant process of adaptation to changing usage requirements and monitoring of operation makes it possible to take advantage of all energy savings potential. Monitoring also allows for the early detection of errors (malfunctions) and thus contributes to operational safety.

Practical test Building automation shows potential
How large energy savings are in a room with room automation when compared to a room without room automation was researched within the scope of a diploma thesis* at the University of Applied Sciences in Berlin. Kieback&Peter devices were used in the study. The results are impressive.
The field test was conducted in two identical classrooms in the Feldmark Primary School in Berlin-Lichtenberg. The building was constructed in 1995. The energy performance of the rooms is comparatively good. A weather-adjusted primary energy consumption of 107 kWh/m²a was calculated for an energy consumption pass. The heating is supplied via district heating. The entire building complex is continuously heated to about 20 °C due to the opening times of the after school program as well as use of the gymnasium by various sport clubs. District heating accounts for about 75 percent of the annual energy costs. Test room with individual room control

Both comparison rooms were provided with heating through a heating system with an external temperaturedependent flow temperature control. In the test room this control was supplemented by an electronic individual room controller. An HRP22-M heating processor served as the control device. The control was wirelessly realized with a MFC and a TC12 room temperature transducer from the technoLink ® product range as well as the MD100Y wireless mini motor actuator. The existing conventional thermostat valves were maintained in the reference room.

Thermal heating consumption with electronic individual room control
A weekly program was stored in the HPR22-M so that the test room could be heated in accordance with the class schedule. For usage times a setpoint temperature of 20 °C was specified, while during nonusage-times the setpoint temperature was reduced to a lower temperature of 16.5 °C. The heating consumption in both comparison rooms was recorded by heat meters in the branch lines and exported via an M-Bus interface.
Thermal heating consumption with thermostatic individual room control
Savings of more than 40 percent are possible
from the result of a thermal building simulation conducted in parallel.
The field test yielded the following results: the room with the conventional thermostat valves had an energy consumption of 111.5 kWh/ m²a. The occupancy-dependent heated test room, on the other hand, required only 63.4 kWh/m²a. Its energy consumption was about 43 percent lower. This result differed only about 1.5 percent
The size of the savings potential depends primarily on how long the rooms are used, and what is being done so that the rooms are not continuously at a high level of heating. Differences in the measurements from 30 to 40 percent show that room automation unlocks great potential for energy savings and can contribute significantly to CO2 reductions.

Building automation More efficient by far
The EU’s “Energy Performance of Buildings Directive“ (EPBD) is a Europe-wide binding standard providing proof of energy efficiency in buildings.
DIN EN 15232 divides residential and non-residential buildings into four different energy efficiency classes according to building automation effectiveness.

The extent of the energy savings to be achieved through building automation depends significantly on the nature and use of the building. Buildings such as schools, hotels or shopping centers that are only occasionally and variably used offer a particularly large savings potential.

Green Buildings On the rise worldwide
Efforts to reduce consumption of natural resources and improve environmental sustainability through buildings are being undertaken not just in Europe but throughout the world. In doing so, the total life cycle of a building is to be considered, starting with planning followed by its use all the way to its demolition. The goal is to build and operate buildings in terms of sustainability. In order for buildings to be sustainable it must primarily be caused by reducing energy consumption. This is to be achieved through the use of renewable energy and by the consistent improvement of energy efficiency. The effort to ensure the sustainability of buildings is supported by various directives, legislation and evaluation systems. Basic principles are also provided to assess the sustainability of a building. A classification system for sustainable building, “Leadership in Energy and Environmental Design” (LEED), was developed in 1998 by the U.S. Green Building Council.
LEED defines a set of standards for environmentally friendly, resource-saving and sustainable construction. With LEED, certification points are assigned in six different categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation and design process. Depending on the score achieved, the buildings are grouped into four classes, from “certified” to “platinum”. The certificates are given separately for different types of buildings. Studies have shown that the additional investment needed to achieve a high level of sustainability is not very high. The cost savings, however, especially in the field of energy, are very high and add up in the course of a life cycle of a building. In Germany, the LEED certification corresponds to the German Seal for Sustainable Building, similarly developed as a comprehensive rating system for sustainable buildings, and which has been given since 2009 by the German Sustainable Building Council e. V. (DGNB).
The Reichstag building in Berlin meets many criteria for “Green Buildings”. Its energy efficient building automation is from Kieback&Peter.

Return on Investment Building automation pays for itself
Savings from day one Saving effects through
maintenance and service Low costs through
integrated planning
Building automation is not only a very effective lever for reducing CO2 emissions, but is also profitable: The savings from lower energy costs exceed the additional costs of higher initial investments in a very short time. In 2007, the consulting firm, McKinsey&Company had already pointed this out in a study issued by the Federation of German Industry (BDI) - “Costs and potentials for the prevention of greenhouse gas emissions in Germany”. The concrete calculation for a building depends on its characteristics and use on the one hand, and on variable factors like building costs, energy prices and not least the financing costs, on the other hand. Indeed, there are many investigations which confirm the economic efficiency of building automation. This is true for new buildings as well as for the renovation of existing constructions. With new buildings, the assumption taken is that building automation accounts for approximately 1 to 2 percent of the overall cost. However, savings are achieved from the first day of operation through lower energy consumption. Building automation offers other possibilities for saving, for instance if it is used for maintenance and repair services as well as the constant control of consumption and energy optimization. The return on investment is often already reached after three to four years. Looking at the whole life cycle of a building, the saving potential amounts to many times the necessary investments.
Along with the reduction of investments and life cycle costs of buildings, planning also plays an important role. A prerequisite for efficient building automation is integrative planning of different trades instead of individual planning. In a finished building, comprehensive, trade-spanning, intelligent automation offers the best conditions for long-term cost savings.

The Community of Beckerich in Luxembourg Intelligent climate protectors
Beckerich, a 2,100-inhabitant community in Luxembourg is considered a “climate protection metropolis”. Beckerich is on the way to becoming entirely independent of fossil energy sources in the production of electricity and heat.
This way many projects were permuted. Two biogas plants and a woodchip heating system provide heating and environment-friendly electricity. A district heating network supplies most of the households and almost all public buildings with heating. Good insulation in the houses and solar collectors on the roofs are almost totally standard. Green electricity finds many buyers as well. As of today, 90 percent of the electricity demand and 40 percent of the heating demand come from own renewable energy sources. Their commitment was recognized several times, as with the “European Solar Prize 2008” in the category for cities and communities, for example. Foundation of the success The foundation of the success is also due to powerful technology. This includes the integration and regulation of all important buildings and installations into one automation system.

This applies for the entire village, including several churches, a school, a day-care center, an old mill that is used as a restaurant, the fire department, a building on the sports field, the cultural center, a gymnasium and the city hall. In addition, the biogas plant, the woodchip heating system and the district heating network are all integrated. Even the water supply is monitored by the system, from its extraction at the springs up to the distribution and measurement of water consumption. The Kieback&Peter Neutrino-GLT central building management system monitors and operates the automation system. Neutrino-GLT administers about 7,500 data points, provides information on malfunctions and offers the possibility for constant optimization of all equipment.

Guenzburg Regional Hospital – Saving energy through integration
The complex technical equipment at hospitals requires a lot of energy. Potential energy savings can be tapped and used sustainably with building automation and related services. Moreover, building automation also improves the operational reliability and enhances comfort for patients and staff. Ludwigshafen Klinikum – economic efficiency through preventative maintenance With 1,010 beds, the Klinikum in the city of Ludwigshafen is the second largest hospital in Rhinehand Palatinate. The technical equipment includes a boiler house, clean steam generator, 28 heating sub-stations, 33 ventilation systems, of which 13 are full HVAC systems, 2 absorption chillers, a recooling system and an emergency diesel generator. These are monitored by the Kieback&Peter building management system, as are the medium and low voltage systems, the lighting control and the fire alarm center. Immediately after the project’s completion a maintenance contract was finalized, which offers the customer the following benefits: increasing plant reliability and availability, increase in the lifetime of the equipment, energy cost savings, and early detection of damage to the equipment.
The Guenzburg Regional Hospital is a specialty hospital for psychiatry, neurology and neurosurgery. In the course of renovation existing field devices (sensors, pressure transducers, actuators, etc.) from other manufacturers were integrated in an automation system from Kieback&Peter. Input and output modules transmit their data to 85 automation stations. These control and regulate the primary equipment for heating, cooling and ventilation. Energy management and meter management for a total of over 350 meters (for power, gas, water, and heat and cooling quantities) are integrated in the Neutrino-GLT building management system.

Energy consumption As much as needed, as little as possible Building automation improves energy efficiency while regulating operational equipment for the production, acquisition and distribution of energy depending on user behavior and requirements. The motto here is: “As much as needed, as little as possible”. Complete integration An important prerequisite for this is the complete integration of all equipment and functions within the building automation system. System integration enables intelligent interaction of all components and thus provides energy efficient operation. This begins in the individual room. Room automation systems monitor temperature, air quality, lighting, occupancy, window status and automatically regulate environmental conditions exactly as required. The primary equipment, such as boilers or chillers, is also accordingly regulated so that only as much heating and cooling energy is produced as is needed for the operation of the building. The acquisition, storage and analysis of consumption and equipment data within the building management system allows additional optimization and opens up further potential savings.

Room automation Energy efficiency and convenience The cheapest and most environmentally friendly energy is the energy that is not consumed. This energy is also referred to as “negawatts”. Room automation systems from Kieback&Peter produces “negawatts” while regulating heating, ventilation, and lighting as needed in the room. For instance, the heating and cooling is only used when a room is being used. This saves energy.

Room automation Efficiency through intelligence Sensors acquire the temperature, air quality and lighting conditions in the room. They also detect whether the room is currently being used and whether the windows are open or closed. This data is used for intelligent control strategies that are implemented in the control commands. The lighting is turned on, off or dimmed as needed, and the heating and ventilation are also controlled accordingly. The user finds just the right comfort level. If the room is not being used the equipment is shut down or runs on energy savings mode.
Room automation saves energy not only by providing heat or lighting only when needed. Room auto mation also optimizes the use of natural resources such as the sun’s light and heat radiation. The intelligent control of sun blinds saves electricity for artificial lighting. Additionally, sun blinds can support heating and cooling by letting the winter sunlight into the building and keeping it out in the summer.

Efficient room automation With technolon® and technoLink®
A prerequisite for efficient room automation is the communication of the components and devices between each other and with the building automation system. LON ® technology offers one possibility. The technolon® system room controllers and transducers from Kieback&Peter communicate via LON ®.
Wireless communication can also be used in room automation. The Kieback&Peter technoLink® system uses the EnOcean wireless technology. technoLink® does not need cables either for communication or for its power supply. technoLink® is thus an ideal solution everywhere cables would be an interference, where subsequent cabling is too complex or where maximum flexibility is required. Thermal loads from cables can also be reduced with technoLink®. The omission of cables reduces the thermal load. RCN-L room controller – certified efficiency
