Solution Overview
Problem
Conventional building automation systems fail to coordinate various measures effectively to achieve energy-efficient room climate control, often requiring complex and costly simulation processes to determine optimal parameters, and lack the ability to accurately assess time and energy requirements for climate adjustments.
Innovation Solution
An operating method that collects and uses empirical information to determine the time and energy required to achieve specific building zone climates, allowing for the calculation of optimal measures to achieve these climates efficiently, either quickly or with minimal energy expenditure, while considering user preferences for energy-time tradeoffs.

Engineering Contradiction Analysis
1Loss of energy
If conventional control systems use separate control circuits for each room climate parameter, then the control system structure is simple, but the coordination between different climate measures is poor leading to energy inefficiency
Solution Approach 1:
The patent combines multiple separate control circuits into a single integrated control system that coordinates heating, cooling, shading, and ventilation measures together. This integration enables the system to evaluate and coordinate different climate measures globally, improving energy efficiency while managing complexity through unified control logic.
Solution Approach 2:
The control system is designed to handle multiple climate control functions (heating, cooling, shading, ventilation) through a single multi-functional platform. This universal approach allows the system to optimize energy consumption across all climate measures simultaneously rather than treating each parameter independently.
2Measurement precision
If building automation systems are programmed and parameterized specifically for each building using complex simulation processes, then the control accuracy for that building is improved, but the installation effort and costs increase
Solution Approach 1:
The system performs self-characterization by automatically measuring and storing the thermal response of the building zone during operation. Instead of requiring complex pre-simulation and manual parameterization, the system learns the building's thermal behavior through actual operation, eliminating the need for costly simulation processes while maintaining high control accuracy.
Solution Approach 2:
The system dynamically adjusts control parameters based on measured thermal response characteristics rather than using fixed parameters from simulations. This adaptive approach allows the system to optimize control accuracy for each specific building zone automatically during operation, without requiring manual parameterization or complex pre-programming.
3Productivity
If conventional control systems do not track time and energy requirements for climate adjustments, then the system operation is simple, but the ability to optimize between speed and energy consumption is lost
Solution Approach 1:
The system continuously monitors and records the time and energy consumption of climate adjustments, using this feedback to optimize future control decisions. By tracking actual performance data, the system can determine the most efficient balance between achieving climate goals quickly versus minimizing energy consumption, improving overall productivity while managing complexity through data-driven optimization.
