3. Cooperation between WUT and NTNU During the last 15 years Warsaw University of Technology (WUT) and the Norwegian University of Science and Technology (NTNU) in Trondheim have established 3 interdisciplinary research projects related to sustainability of buildings:  “SURE-BUILD – Sustainable Redevelopment of Buildings in Poland” (2002-2005),  “STEP – Sustainable Thermo-modernization of Public buildings” (2006-2011)  “KOD nZEB” Thermo-modernization of two chosen Public Buildings according to nZEB Standards (2015- 2018).

4. Project SUREBUILD (2002-2005)  The goals defined in 2002 were very general: Support to scientific cooperation in the areas of specific importance for both countries, Norway and Poland Promoting the idea of sustainable development in light of ratification of the Kyoto protocol Recognition of the countries’ markets for future economic cooperation in the building sector.

8. Comparison of the economies The ratio of GDP per Capita for Norway and Poland has distinctly decreased from more than 16 in 1990 to nearly 7 in 2015. According to Eurostat Data the purchasing power parity ratio for 2014 was around 2,6. Source: http://data.worldbank.org

Energy use in buildings in Norway is very strongly dependent on electricity, so conversion factors for different energy sources are not used.

12. Project KOD nZEB The goals:  Improvement of knowledge of Polish experts/engineers in the field of nearly zero-energy buildings technologies,  Transfer of know-how from Norway to Poland with an analysis of applicability of the solutions in Polish conditions,  Verification of the developed concepts on two real public utility buildings (preparation of functional and utilization programs for modernization to nZEB standard),  Development of the models for optimal financing of building modernization to nZEB standards.

16. Conclusions  The analysis presented in the paper indicates that the problems do not occur at the academic level. The problems multiply rapidly in the phase of practical implementation. This is related primarily to the following factors observed in Poland:  The substantial difference of national prosperity,  The low level acceptance of the idea of sustainable development expressed by authorities and ordinary citizens,  Size of the construction sector and poor technical condition of buildings,  Limited access to mechanisms supporting the process of construction and sustainable modernization of buildings,  The specificity of the energy mix of Poland (very strong dependence of the economy on coal) especially taking into account that Norway has very large share of electric energy produced by hydro power plants,  A method of aggregating the energy consumption of different carriers.

17. This research was performed with the financial support of EEA Financial Mechanism 2009-2014 – Operational Program PL04 “Saving energy and promoting renewable energy source” within the framework of the“ project: “Thermo-modernization of two chosen Public Buildings according to nZEB Standards”. Through the funds EEA and Norwegian funds, Iceland, Liechtenstein and Norway contribute to reducing social and economic inequality and strengthening bilateral relations with beneficiary countries in Europe. These three countries closely cooperate with the EC on the basis of the Agreement on the European Economic Area (EEA Agreement). Thank you!
