On the other hand, BPS tools also provoke the acquisition of knowledge to non-professional users. One of the difficulties he faces when learning to use BPS tools, which is considered "obstructive" at times, is to deal with uncertainty; Because the constructed environment incorporates arbitrary complexity, where the parameters are abundant but never sufficient in dynamic simulation. This is when the user acknowledges such a complexity and the BPS push them to strengthen their background to identify the most influential parameters. A BPS approach does not necessarily generate something first, but stimulates the user to understand the model through the disparity between the expectations and the simulated results of the inappropriate entries. Regarding this matter, Bellinger (2004) concluded: "After having been involved in numerous modeling and simulation efforts, which produced much less than the desired results, the legal questions becomes: why? The answer is found In two areas. First, we must admit that we simply do not understand. And, second, we must continue to understand. It does not respond but understanding. "

Stes - a student project as a BPS application

In Hamk Tech, BPS has been practiced in the planning and design of small-scale underground seasonal energy storage (STS) as a student project in 2018. The idea is to capture the thermal energy from renewable sources, transfer it to a Thermal storage medium or a mixture of means when the heat is abundant and extracts the heat when necessary (Figure 1). Stes, again, is not a new concept, but its practice and application in Finland are still unpopular. The team points to the production of a complete STE system as a small-scale advanced energy solution, with the help of the BPS tool. The arguments for and against the buildings were evaluated when applied to Finnish construction conditions. In the end, the advantages were delayed to overcome the drawbacks, in the case of building a small small stern that serves a single-family house. The notable point is found in the Finnish favorable meteorological properties, which have high levels of solar radiation while imposing a low demand for heating in summer.
