The numerical modelling of spectators and performers’ comfort in large concert halls was considered. The research shows that numerical modeling of air velocity and temperature helps to make a justified choice of technical solutions for ventilation and air conditioning systems and to examine their operation under extreme mode of service as well.

One of the most promising applications of highly effective computer technology (supercomputers) is numerical simulation of complex physical and thermophysical proccesses occuring in vast areas of concert halls and sport arenas while heating, ventilating and air conditioning. According to Russian technical standarts for building construction, numerical modeling of these systems should be carried out on the stage of their design. The variety of problems and demands, lack of understanding of the physical process involved and the necessity to make genuine decisions are encountered while conducting such a work. The experience in modeling of ventilation and air conditioning systems of Bolshoi Krenlevskyi Palace concert halls and the Moscow Conservatory named after P.I. Chaikovskyi, Zaryadie Park Philarmony concert hall and a covered ice rink arena is described.

Article is devoted to the peculiarities of creating an electronic course on learning the basics of three-dimensional design of wind power plant elements using modern software systems. The iSpring Suite program was chosen as a course development tool. It has support for the SCORM 2004 format and extensive integration with office suites. In order to minimize problems with working in various distance learning systems, the course was divided into nine modules. The first module is dedicated to the basics of wind energy. The second module provides an overview of existing CAD programs. The third and fourth modules are dedicated to 2dimensional design. The fifth and sixth modules introduce commands for creating 3-dimensional parts from both other parts and 2-dimensional sketches. Module 7 is devoted to algorithms for creating assemblies from existing 3-dimensional parts. Module 8 and 9 represent the implementation of the multiplier/reducer Assembly algorithm from ready-made 3dimensional parts that are present in the course resources.
