Building services engineering (BSE) planning is a complex task that requires a high level of expertise - but lays the foundation for efficient building planning right from the start. But which MEP software and processes are tried and tested? How do you increase energy efficiency without losing sight of sustainability?
TGA planning can be compared to the human body. While the façade, load-bearing walls and the solid foundation correspond to the human skeleton, the components of the building processes take on the function of the finely chiseled blood circulation - arteries, veins and the heart, which keeps the core parts of the building alive without disruption.

In this article, we have summarized the most important factors for effective building technology planning based on our tried-and-tested expert knowledge.
The most important facts in brief
TGA planning is a complex field and includes the complete planning of building technology during the construction process
Modern software solutions standardize planning processes
Detailed TGA concepts increase the effectiveness of processes and reduce costs sustainably
TGA software - a system for greater efficiency
The technical building equipment plays a decisive role in the design of the interior of buildings - and is one of the most complex fields of modern construction processes. Accordingly, only a precisely balanced planning system can guarantee trouble-free building processes in the long term.
TGA planning ensures a reliable supply of electricity, water and heat and covers all relevant technical aspects such as electrical engineering, energy planning, sanitary engineering, heating, air conditioning and ventilation technology. Only with efficient planning can buildings be used optimally and offer a pleasant indoor climate.
As in modern medicine for the treatment of the human body, experts can also use complex observation and planning tools for the building cycle. Software solutions for building information modeling (BIM) enable holistic technical building services planning and the handling of even large building services projects - with seamless integration of CAD and detailed model calculations.
What is all part of modern technical building equipment?
TGA planning is an essential part of modern technical building equipment. The term refers to the planning, installation and maintenance of technical systems in a building in order to optimize operation as much as possible.
These systems can include heating, air conditioning, lighting, ventilation and sanitary facilities, etc. Professional MEP planning enables the building owner to maximize the energy efficiency of the building. Each system can be selected and installed to meet the building's requirements in terms of safety, comfort and energy efficiency.
Cleanroom equipment and technology are specially designed environments with low levels of airborne particles and other contaminants to protect manufactured products or processes. When planning a cleanroom facility, the TGA software can provide important data about the air flows, heat load and pressure in the room.
At the same time, the right planning can not only save costs, but also avoid excessive investment. Professional MEP planning is therefore essential for every project.
Knowledge is planning power
However, in order for planners to do their job professionally, it is essential that they have all the relevant information about the building and its users.
This includes, for example, information on the size of the building, the number of rooms and corridors as well as details of existing structures such as water pipes or electrical wiring.
Technology as a planning key
In order to maintain an overview of these complex structures, it is advisable to use specialized software solutions. Different areas have to be harmonized and coordinated with each other. In addition, numerous prescribed standards and guidelines such as DIN, VDI or VDE must be observed - a difficult undertaking without expert tools.
BIM-capable CAD and calculation applications, for example, significantly increase the holistic handling of building technology projects. Integrated CAD applications and the seamless transfer of complex 3D models, key planning figures and specific calculations also ensure a workflow that is as trouble-free as possible.
The advantages of an effective CAD system for your TGA planning
An effective CAD system is an indispensable tool for successful MEP planning. It not only enables the creation of precise and detailed 2D and 3D drawings, but also the integration of important data such as material lists and cost calculations.
To ensure that planning runs smoothly and efficiently, you need a powerful CAD system. This CAD system allows you to create complex MEP plans with minimal effort.
TGA concepts for maximum time savings
An effective CAD system ensures speed and time savings in the planning cycle - and is therefore one of the most important advantages in the field of MEP and in the design of technical systems. We have summarized other factors in more detail here.

With the right system, there is movement in the individual parts of the cycle. The planning of the building equipment can thus be carried out much faster than would be possible with traditional manual planning - because data can be seamlessly integrated into further planning without manual data transfer.
At the same time, all information is immediately available in digital form, enabling the CAD system to calculate and display the exact dimensions of the components. This minimizes errors and optimizes the end result - and keeps the individual processes moving efficiently.
Holistic systems for complex networks
An additional advantage of using a CAD system in your MEP planning is the accessibility of all information via a shared data environment. This enables the various project departments to access the same data and to change or edit the plans without everyone having to invest additional time in their work.
For anyone working on more complex projects, a powerful CAD system offers even more advantages: Imagine you have to create or change several plans at the same time - with the right CAD system, you can complete these tasks much more easily and precisely than with manual methods.
Data exchange between different programs is also significantly simplified: all relevant files can be imported and exported directly, so that no more time is wasted on manual conversions.
With a system for an optimized workflow
Modern and field-proven software solutions from Trimble, such as Trimble Nova, combine all these significant advantages in a holistic and system-independent platform - and thus optimize complex projects of all sizes.
With the TGA software, you can combine design and calculation to ensure an efficient process. With the help of accurate calculations that result directly from the drawings, you can shorten the project duration and reliably eliminate potential sources of error.
Trimble, your competent partner for successful TGA planning
Precisely thought-out technical building equipment is essential for the design of the interior of buildings. This is an extremely complex field that plays a decisive role in modern construction processes - and can hardly be managed with manual instruments given the diversity of planning and processes involved.
Trimble Nova - a powerful CAD and calculation software that enables building services projects to be handled comprehensively - provides a remedy. With its own CAD core, integrated calculations, 3D modeling capability, collision checks and accurate manufacturer data, it offers a smooth BIM workflow.
Trimble Connect is the ideal addition for optimized networking within larger teams. With this tool, you can connect all project participants with the necessary data at the right time.
Both tools are used to bring buildings and their corresponding concepts to life. If the individual processes correspond to the organs in the human body, they network the tools with each other, ensure movement in the cycle and a constant flow of data.
This is because the availability of execution-ready information in Trimble Connect improves control over the project, enables informed decision-making and optimizes efficiency within the team - and, as the arteries and heart of planning, ensures the smooth circulation of information.
