Saving energy at the cost of users?

Buildings consume about 40 percent of the primary energy in Europe. They are therefore key to the economy, environment and climate protection. Huge potential savings lie dormant in old buildings. But buildings also play an important role for us as people: we spend about 80 percent of our lives in buildings. They are the most important places in our daily lives. If we want to improve the efficiency of buildings, this must be in harmony with building users and their needs. A livable environment is the essential basis for well-being, health and productivity. At Kieback&Peter, saving energy doesn’t mean freezing in winter and sweating in summer: with our smart solutions, we optimize building efficiency without affecting the comfort of users. On the contrary: we even improve comfort – with optimized heating and ventilation, for example.

Predictive control MPC 2.0

Optimizing HVAC control by using artificial intelligence (AI)

Model Predictive Control (MPC) is a predictive control system based on mathematical models. MPC works with predictive algorithms and appropriate control commands. The MPC programs are based on complex calculation models which also take account of the inertia of buildings and technical systems. As well as real-time values, they work with other factors, e.g. historical system data.

MPC 2.0 from Kieback&Peter goes two steps further in digital evolution: the smart control also uses external data such as visitor and climate forecasts. And it works with artificial intelligence (AI) – the algorithms of MPC 2.0 are continually developing through machine learning. The intelligent controller becomes ever more familiar with user, building and HVAC system behavior. For example, MPC 2.0 learns how slowly individual rooms cool down. With this knowledge, MPC 2.0 lowers the temperature well before the end of the day. The good thing is that users don’t notice it because there is enough residual heat to maintain comfort levels. Another example: if the weather forecast is for an unusually warm fall day, MPC 2.0 reduces the feed temperature in the early morning. MPC 2.0 understands the physical and technical interrelationship of all the systems as a whole. The smart control system is thus able not only to optimize efficiency and comfort continuously. It can also manage the peak loads of entire properties in such a way that operators can exploit price advantages on the energy and resource markets.

Service benefits at a glance

You do not have to modernize your entire system or building automation to be able to use our smart service. MPC 2.0 builds on existing systems and can be integrated cost-effectively with little effort.

Before we can optimize your control system with MPC 2.0, we have to compile and analyze your system and consumption data. If you have not yet managed to consolidate your data, this is the perfect opportunity to do so: our solutions create clarity about the status quo of your HVAC systems. Only if we have a clear picture of their condition do we know where to start with optimization. It is important to us that you can see the success of these measures clearly. That’s the only way to create acceptance and trust for all concerned.

MPC 2.0 from Kieback&Peter optimizes control of your heating, ventilation and A/C systems. With MPC 2.0, you save about 20 percent of your energy compared to a conventional control system. And users benefit palpably from greater comfort.

Smart A/C control improves comfort and efficiency

Older buildings often use poorly controlled ventilation that is not much fun for anyone: operators are annoyed by the high energy consumption. Users complain about the unpleasant climate indoors, draughts around their necks, dry eyes and even headaches. Kieback&Peter has a quick, cost-effective remedy: we optimize your ventilation system by switching to needs-based control. This often saves half of the electricity costs immediately. With our premium Climotion solution, we get the absolute maximum of comfort and efficiency out of your ventilation system: the patented algorithm distributes the air slowly and evenly in a room or zone. Say goodbye to temperature layers, draughts, islands of heat and cold. Climotion means: the perfect climate for users. And up to 30 percent energy saving for the operator.

What is Climotion and what is the use?

Climotion improves the comfort and efficiency of ventilation systems. The advantages to operators and users are:

  • 30 percent lower energy costs on average
  • Reduction in CO2 emissions
  • Pleasant, healthy indoor climate
  • Optimal mixing of intake air and room air
  • Suitable for new/existing buildings
  • Ideal even for challenging building types and uses
  • Less ventilation noise thanks to lower power consumption

Needs-based control massively reduces the energy consumption of ventilation systems. The rule of thumb here is: if you halve the volume flow, the power consumption of the fans will fall to one eighth. Kieback&Peter smart control systems determine ventilation requirements via sensors – so the system is controlled by room air parameters (DIN EN 13779 IDA C6). Climotion has another efficiency advantage: the algorithm ensures that air is distributed optimally in the room and prevents ventilation short-circuits and the associated control errors. This saves energy by about 30 percent.

Without Climotion: ventilation systems with normal control systems often have a short-circuit. That means: the intake air flows too quickly from inlet to outlet – the room is only ventilated between the two. This creates an unpleasant draught, while the air outside this area hardly moves at all. Unpleasant temperature and pollutant islands are created that cause discomfort and medical conditions among users.

With Climotion: the smart control algorithm create a slow, undirected flow. It controls the intake and exhaust air separately and ensures that the fresh air is mixed with the existing air evenly throughout the room. Climotion also reduces the ventilation noise because it cuts the power consumption of the fans. Climotion therefore offers room users a double comfort benefit.

Climotion is not only ideal for new builds. Existing systems can also be retrofitted easily without much building work. Climotion is suitable for all ventilation systems with external air and for almost all building types – from office buildings to football stadiums. With its homogeneous air distribution, Climotion is particularly suitable for buildings with special climate requirements – museums, libraries, theaters, concert halls and swimming pools, for example.

Kieback&Peter is one of the leading experts in ventilation optimization. Our Climotion team has already successfully completed over 200 optimization projects – in the famous Starlight Express musical theater in Bochum, for example, and in the renowned Arp Museum in Remagen.
