The main purposes of this project is to study and approach, then masters the research method and collaborate with foreign partner for building of maths-physics model for simulating thermal regime of energy saving buildings which use renewable energy sources (RE).

Theoretical results:

• (1) Grasped the research method, mastered the algorithm and calculation model of thermal regime of multi-storey buildings and construction design process for green energy buildings.

• (2) Built algorithm and program (on the computer) for calculating energy characteristics of energy saving buildings.

Established computing maths-physics model to simulate thermal regime of civil, energy saving buildings to calculate for conditions in the North of Vietnam with utilization of renewable energy (to be more precise, it is the solar heat for hot water supply purpose for buildings), allowing research and assessment of thermal regime of buildings.

• (3) Mastered the methods, algorithms, model for calculating, selecting architectural and structural solutions for high-rise, green energy buildings of Belarus; researching adaptation ability and transferring suitable methods for conditions of Vietnam and perfecting to apply for Vietnam.

• (4) Trained some research staffs of Institute of Energy Science in studying thermal transferring regime of multi-storey, green energy buildings.

Applied results: Based on the research contents, NIPTIS Institute has proposed, modified and added some criteria for evaluating technical-economic effectiveness of energy saving buildings, and built some new high-rise complex buildings according to the green energy building standard of Belarus.

Computing maths-physics model to simulate thermal regime of civil, energy saving buildings which use renewable energy was created (to be more precise, it is the solar heat for hot water supply purpose for buildings), allowing research and assessment of thermal regime of buildings.

Technological products (describe in details technical characteristics, place): Conclusion report and summary of research results of this project are saved at the Information and Documentation Center as regulated at Decision 33/QD-VHL on 04/03/2013 regarding regulations on building and managing international cooperation duty in science and technology at the level of Vietnam Academy of Science and Technology.

The application research results of calculation program of this duty can be served for making technical standard code of energy demand guarantee system in the effective using and energy saving buildings with conditions of Vietnam.

To completely solve the energy saving issue in the buildings, it is necessary to have synchronous and comprehensive research about the heating and cooling requirements and hot water supply demand for living activities. In which, concentrated hot water supply systems using solar energy, heat pump and geo-thermal need to be studied and applied.

The project team tried utmost to finish comprehensively all the goals and contents set by the project. We request the responsible authorities to verify and approve the results.
