Heat Pumps for Office Buildings: A Sustainable Solution
Heat pumps have become the heating system of choice in newly built single and double-family homes and are increasingly found in district heating networks as well. However, the situation is different for commercial and industrial applications - the potential of heat pumps is still underutilized in these sectors. This is partly due to limited awareness of best practice examples that could build trust in new solutions.
Heat pump systems are still not often considered for demanding large-scale projects, as conventional heating, ventilation, and cooling solutions are more familiar and therefore preferred.
This deficit needs to be addressed because commercial and industrial processes, like buildings, equally rely on the provision of heat and cold. A heat pump can provide both using renewable energy sources, making the separation of heating and cooling devices obsolete. Ideally, simultaneous heating and cooling needs exist, which can be efficiently met by heat pumps with unbeatable efficiency. With a well-designed heat pump system, significant energy and thus economic savings are possible, benefiting the environment as well.
The limited use of heat pumps in commercial areas such as office buildings and industrial halls, as well as in existing buildings, is regrettable. Especially in such environments, heat pumps offer great potential to increase energy efficiency and reduce costs. By implementing heat pumps in commercial operations, both heating and cooling needs can be efficiently met, rendering conventional heating and cooling systems unnecessary. This can lead to significant savings while reducing environmental impact.
It is important to raise awareness of the benefits of heat pumps in commercial and industrial settings. Demonstrating successful application examples can build trust and acceptance for this innovative technology. Commercial and industrial companies should seriously consider the possibility of transitioning to heat pump systems to reap the various economic and ecological benefits.
How does a heat pump work?
A heat pump utilizes the principle of thermodynamics to transfer heat energy from a lower temperature to a higher temperature. This is done using a refrigerant circulating in a loop. Initially, the refrigerant vaporizes by absorbing heat from the surroundings.
Then, the gaseous refrigerant is compressed, increasing its temperature. The heated air is then released to the heating system via a heat exchanger, while the refrigerant condenses, releasing the heat. The cycle is then restarted. Through this process, a heat pump efficiently extracts heat energy from the surroundings and utilizes it for heating purposes.
Air-Water Heat Pumps in Office Buildings
Air-water heat pumps and air-air heat pumps are proven and effective solutions for heating office buildings. These systems utilize outdoor air as a heat source and use a refrigerant that vaporizes at low temperatures. This refrigerant is then compressed by a compressor and heated to transfer the acquired heat to the heating system. Installation is relatively simple and straightforward, as it does not require a complex duct or piping system and can often be placed outside the building.
Air-water heat pumps can be particularly efficient when used in combination with underfloor or wall heating systems. These heating systems operate at lower flow temperatures, contributing to further efficiency. Therefore, they are an attractive option for office buildings seeking a flexible and efficient heating solution. An alternative option is the ground-water heat pump, which can be operated in combination with similar systems.
Ground and Groundwater Heat Pumps for Offices
Ground-source heat pumps and groundwater heat pumps are another efficient heating solution for office buildings. Although they require open space and earthworks in the garden during installation, they offer high efficiency rates and can lead to significant long-term energy cost savings. Low-temperature radiators can be used in combination with these heat pumps to further increase efficiency. To make the most out of this solution, you can follow some tips recommended by experts.
Although they require more space and groundwork than air-water heat pumps, ground-source and groundwater heat pumps can be an attractive option for office buildings, especially when long-term energy cost savings and environmental friendliness are prioritized.
Integration of Heat Pumps into Existing Office Buildings
Both air-water heat pumps and ground-source and groundwater heat pumps can be integrated into existing office buildings. While air-water heat pumps are often recommended due to their flexibility, both types of heat pumps offer advantages that can be maximized through careful planning and adjustments.
One way to integrate heat pumps into existing heating systems is bivalent operation, a hybrid solution that allows the heat pump to be connected to the existing heating system. This can be particularly beneficial for older buildings that cannot or should not be fully converted to a heat pump.
Another challenge in integrating heat pumps into existing office buildings is optimizing efficiency. Factors such as heat source temperature and technological innovations play a crucial role. To overcome these challenges, further adjustments and optimizations are necessary, which we will discuss in the following sections.

Heat Pump for Industrial Halls
Industrial halls often require larger heating and cooling capacities to maintain worker comfort while meeting process cooling requirements.
A heat pump for an industrial hall provides an efficient way to generate or remove heat, depending on the hall's requirements.
A typical application for an industrial hall could be an air-water heat pump. This type of heat pump extracts heat from outdoor air and uses it to heat water. This warm water can then be used to heat the hall.
Another option is to use groundwater heat pumps. These heat pumps use geothermal heat by extracting heat from the ground and also use it to heat the hall. The choice of the right heat pump solution for an industrial hall depends on various factors, including the hall's size, specific heating and cooling needs, and local conditions. It is advisable to seek advice from professionals to find the optimal solution for each industrial hall.

Conversion to Heat Pumps: Challenges and Solutions
The conversion to heat pumps is a complex process that requires careful planning and execution. One of the main tasks is to determine and lower the supply temperature while improving building insulation. These steps are crucial to maximize the efficiency of the heat pump and minimize operating costs.
Additionally, external factors such as ambient temperatures and the availability of heat sources can influence the performance of heat pumps. Therefore, it is of great importance to consider these factors in the planning and implementation of conversion projects.
Combination with renewable energies
Combining heat pumps with renewable energies offers another way to increase efficiency and sustainability. By utilizing renewable energy sources, the operating costs of heat pumps can be further reduced, and CO2 emissions can be reduced.
An example of combining heat pumps with renewable energies is the use of photovoltaic systems. These systems generate electricity on-site, which can be directly used to power the heat pumps. Another example is the combination with solar thermal systems, which generate additional heat and can further increase the efficiency of heat pumps.
Photovoltaic systems for powering heat pumps:
Photovoltaic systems can significantly reduce the electricity demand of heat pumps and increase the self-consumption of the generated electricity. By using special inverter heat pumps that operate at variable speeds, the performance can be effectively adjusted to match the heat demand.
Additionally, the use of solar power storage systems can increase independence from the grid, as surplus energy can be stored and utilized later. This significantly enhances a building's self-sufficiency in terms of electricity supply.
