Energy efficiency in the building area
When they think of the energy revolution, many people think first about using renewable energy sources. However, at the same time it is important to reduce energy consumption. Buildings offer a high potential for saving energy, since they are the cause of around 35 percent of Germany's total energy consumption. Making buildings more energy efficient by optimising their energy consumption in operation is an important key to reducing consumption in a sustainable way. That means energy efficiency is essential for everyone from architects and planners to operators and final users.
Reducing CO2 emissions is the goal
Warm rooms in the winter, cooling in the summer, lighting at night, quick means of transportation, operating machinery and equipment – it takes a lot of energy to live the way we do. However, the majority of our power supply comes from fossil fuels, and burning these fuels generates CO2 emissions. Today, we know that this is very likely a cause for the alarming pace at which climate change is advancing.
Climate protection targets
The following binding targets were established for Germany under the Federal Climate Protection Act (Bundes-Klimaschutzgesetz (KSG)) of 24/06/2021:
- Greenhouse gas reduction of 65 percent compared to 1990 levels by 2030
- Greenhouse gas neutrality by 2045

GEZE products for energy-efficient buildings
With integrated solutions for door, window, and safety technology focused on energy efficiency, it is possible to combine comfort and safety with energy efficiency in a smart way. Interdisciplinary networking also creates all new options for energy-saving building management. GEZE makes a significant contribution to energy efficiency through different products and solutions:
- natural ventilation and exhaust of buildings, as well as single room temperature control via automated window systems
- automatic opening and reliable closing of doors
- myGEZE Control intelligent building automation system for smart integration of door, window, and safety technology into the building automation system. Depending on the outside temperature, for example, the opening widths of doors can be adjusted automatically or windows can be opened or closed accordingly in coordination with temperature sensors and heating systems.
Saving energy with natural ventilation
Natural building ventilation saves a significant amount of energy and resources and eliminates the need for energy-intensive air conditioning systems. Mechanical air conditioning systems require a very large amount of energy. In addition to the large area they take up in the building, which is no longer available for other uses, high investment, maintenance and operating costs make such systems seem an unprofitable choice. Regulated natural ventilation, in contrast, is clearly an advantage. “Intelligent” drives and control panels from GEZE that can be used to open and close façade and roof windows in a controlled manner ensure energy-saving and environmentally-friendly ventilation and exhaust. For instance, they facilitate automatic night-time cooling, which is a cost- and energy-efficient method for cooling buildings compared to an air conditioning system.
Comfortable building automation for better energy efficiency
GEZE technology can be used to control façade elements, whether doors or windows, based on current needs. Each window can be controlled individually. Temperature and CO2 sensors, timers and rain-wind sensors open and close windows automatically. The new myGEZE Control building automation system can also be used to centrally visualise, control and manage automatic doors and windows.
At GEZE, we have understood that buildings make an important contribution to sustainably reducing energy consumption and therefore CO2 emissions. That’s why smart and energy-saving solutions are more than ever the focus for our customers and us.

More than energy efficiency: sustainable building (green building)
GEZE is facilitating sustainable building, also known as “green building” through its products. Green building means modern, sustainable environmentally-friendly building construction and renovation in harmony with humans and nature. The buildings stand out for their efficient use of resources such as energy, water, and materials. At the same time, harmful impacts on health and the environment are also reduced. The guiding principle of sustainability is pursued throughout the complete building life cycle as far as possible, starting from project development, planning, and design to operation and maintenance and to disassembly. A seal was created in Germany in 2007 to reflect this: The certificate of the German Suistainable Building Council (DGNB).
Honoured with the DGNB certificate for sustainability
In the new corporate building of Vector IT in Stuttgart, our customised digital networking solutions help to avoid a total of approximately 460 tons of CO2 emissions per year in ongoing operations. The German Suistainable Building Council awarded the project the DGNB platinum certificate as well as the DGNB diamond for outstanding architecture for this achievement.
Around 120 buildings have already received the DGNB certificate or a previous certificate. These include the building of the Umweltbundesamt Dessau (UBA - German Environment Agency), which is a flagship project of the German state due to the high level of quality it achieves in all aspects of sustainable building, and is one of Germany's most efficient administrative buildings. The door technology in the building comes from GEZE.

Combining digital building planning and sustainability: BIM makes it possible
From investors to architects, specialist planners, installation companies, system vendors, or building product manufacturers: everyone benefits when planning and collaboration are simplified. The same is true for achieving climate targets: Innovative, environmentally-aware and resource-saving solutions are essential to reduce CO2 emissions in the building sector. Building Information Modelling (BIM) facilitates comprehensive, integrated planning. From the draft of a building to its dismantling, it can be used to pursue sustainable project targets and strategies. Because of this, BIM has great potential for helping use resources and building materials in an environmentally-friendly way throughout the entire building life cycle. It can also help reduce the work required for DGNB certification, which saves time, money, and resources.

Information on energy efficiency
Energy-optimised planning
GEZE supports building planning during the earliest stages, and creates energy-saving concepts and solutions. GEZE solutions can also be used to effectively save energy in retrofitting existing buildings.
Advantages of myGEZE Control
- Planning security
- Expansion of the portfolio
- Functional expansion
Customised solutions
Depending on the application scenario, individual solutions are offered with different service packages and relevant hardware and software components, as well as associated services for energy-efficient building.
Products with EPD Environmental product declaration
Some GEZE products, including the TS 4000 and TS 5000 door closer series, have an environmental product declaration (EPD). The EPDs provide the data that serves as the basis for ecological building assessments, and are building blocks in the overall assessment of the building’s environmental performance.
Customised service concepts
In addition to implementing the solutions we develop in buildings, we also offer customised service concepts for each building, to ensure their proper function and operational safety and to retain the value of energy-efficient systems through regular maintenance. This not only provides operators with financial advantages by reducing building operating costs, but also supports them in particular in handling their operators’ responsibilities.
Efficient building management
GEZE Cockpit can be used to check, display, and manage the statuses of doors, windows, smoke and heat extraction systems and emergency exit systems at any time and from anywhere using any IP-enabled device. With this option, GEZE offers convenience, safety, and efficiency in building management.
