Digitization can bring significant improvement to energy efficiency through reduced workloads and faster operations. It can also increase the availability of savings and the most energy-efficient alternative in different situations. Utilizing the results and data continuously would allow the creation of new added value. The pioneers of this change are the winners of digitalisation. It can significantly increase the productivity and reliability of energy efficiency. However, it requires the development of work processes and methods and tools. Only the development of the entire activity will improve the competitiveness and enable the production of added value.

In many discussions with energy efficiency professionals, it has came out that the digitization of existing consumer and technical information does not bring real added value. Decisions can no longer be made on based on mere beliefs or typical repayment periods. Several experiences have also shown that individual Clean Tech solutions do not appear to affect overall consumption as claimed.

All energy efficiency theories and instructions prove that calculations and estimates must be based on the energy balance. Practice has proven that forgetting this principle will lead to wrong solutions.

Our strong experience shows that energy audit manuals, statistical methods, monitoring energy management services, Green Building and Checklist procedures can only produce jargons instead of a genuine energy balance. Energy balance is much more than measured energy consumption.

The world’s largest industry standard, ASHRAE, has also come to the conclusion that the most productive and most reliable level 3 energy audit needs energy balance modeling and energy balance interaction calculation. However, modeling applications have long been unsuitable for energy efficiency. The solutions have designed for the big industry and are excpencive.

The modelling solutions is generally based on CAD images in markets. This has been a natural development step in the design processes that allows a big inaccuracy. In energy efficiency their use, however, is really difficult because CAD images are not found in most of the buildings. Drawings should also be pixel-processed before use. Modifying the drawings usually takes up the entire budget. In addition, the images of all CAD programs are not useful. Typically markets trying to sell value through 3D images, which make possible to rotate the building. The biggest problem with CAD modeling is that they are essentially the sub-optimizers of the components. It lacks the most essential energy balance and its utilization.

It seems that digitalisation winners need to take care not only of the whole process but also of relying on the correct energy balance.
