Responsibility and teaching of it is directly linked with the diploma with which curriculum graduates will be awarded. In Estonia, the graduates will receive the diploma of engineering, i.e. master degree in real estate is related with an MSc in engineering. From this arises a clear vision that responsibility as a subject will be engineering responsibility. According to the common practice, engineers and their professional societies have separate Codes of Ethics that are grounded on general and historical practice in the absence of a regulation like e.g. GAAP for accounting specialists. The teaching must also include philosophical motifs. All students must be teached in a way that they are able to meet real estate market needs. After all, compliance is available if market professionals take part in university practice and also supervise the enterprise-based practice. Due to the small number of curriculums on the one hand and the heretofore limited interest from the side of firms and professional bodies, this is named exactly the basic mainstream for teaching responsibility. It is also evident that different building environment keywords like energy efficiency, sustainability, renewable energy etc must frame the picture. The presentation tries to answer the question how to arrange this on a small real estate education market.
