At the BAU 2025 trade fair in Munich, dormakaba is presenting MotionIQ, an innovative technology that significantly reduces energy loss through automatic doors. Due to precise door control, MotionIQ minimises the time that doors are held open and, depending on the application scenario, enables energy savings of up to 50% compared to standard solutions.
This also contributes to reducing a building's carbon footprint. An assessment of the savings potential for each use case is made possible by dormakaba’s Door Efficiency Calculator, a scientifically validated tool that provides architects and building planners with reliable data for sustainable decisions.
Energy efficiency
The construction and real estate industry plays a central role in achieving climate targets, as building materials and operations worldwide are responsible for around 40% of global CO2 emissions.
The energy balance of buildings, which depends on numerous factors and the products installed, significantly influences this. This is where dormakaba comes in, significantly contributing to optimising energy efficiency with innovative solutions.
MotionIQ: intelligent doors for greater energy efficiency
The centrepiece of the new technology is an intelligent system that analyses and controls door movements
With MotionIQ, dormakaba is revolutionising the process of opening and closing automatic doors. The centrepiece of the new technology is an intelligent system that analyses and controls door movements in real-time.
The system precisely adjusts the door movement to the user's approach speed. This means that the doors do not open any earlier than necessary and close as quickly as possible. Air exchange through open doors is minimised – a decisive step towards reducing heating and cooling energy losses.
Energy savings
Compared to conventional door activation sensors, MotionIQ reduces the unused open time of doors by up to 50%. The result: significantly reduced energy loss, lower operating costs, and CO2 emissions, an extended door life, and safer operations.
MotionIQ, which was previously only available for swing doors, is also available for automatic sliding doors and will be shown for the first time at BAU 2025 together with the automatic energy-saving sliding door ST PRO Green, which has fine-framed, thermally separated profiles.
Example: drugstore
The advantages of MotionIQ are illustrated by a sample calculation for an average-sized drugstore in a city in a temperate climate zone, such as in Western and Central Europe.
In a scenario with approximately 800 visitors daily, six days a week, and an interior temperature of 19°C, using MotionIQ technology alone can avoid a good 25% of CO2 emissions compared to a conventional door system. At the same time, the investment in this technology often pays for itself within just two years through savings in heating and air conditioning costs.
In-depth analyses for sustainable decisions
DEC takes into account specific parameters, such as the location of the building and how frequently the door is used
This calculation of the energy, CO2, and cost efficiency of entrance door solutions is based on the Door Efficiency Calculator (DEC) of dormakaba, which was developed and validated in collaboration with ILK Dresden.
The DEC can be used worldwide. The tool takes into account specific parameters, such as the location of the building and how frequently the door is used, and provides results on thermal energy losses based on scientific modeling.
Door Efficiency Calculator (DEC)
Silvio Tschisgale, project manager at ILK Dresden, says, "dormakaba commissioned our institute to develop the calculation methodology to scientifically validate the Door Efficiency Calculator (DEC)."
"This methodology meets current scientific standards and enables the DEC to make well-founded statements about thermal energy losses in the scenarios considered."
Energy efficiency
Till Reuter, CEO of dormakaba adds, "With innovative solutions such as MotionIQ and the Door Efficiency Calculator, we are setting new standards for energy efficiency in our industry."
"Our solutions minimise energy loss, promote efficient building management, and actively contribute to the reduction of CO2 emissions. For us, climate protection starts at the entrance. We are proud to support architects and construction planners with our solutions and products to create an environmentally friendly future."
