Although sports venues are often referred to as palaces, they are usually metaphorical images of the size of the venue. Rarely would anyone think of directly comparing them with the Winter, Kolomna or Peterhof palaces. However, the Rhythmic Gymnastics Palace of Irina Viner-Usmanova in Luzhniki has grounds for such a name in every sense.

Denis Dubinin, Chief Project Engineer of Metropolis, told "Construction Weekly" about the design features of a new multifunctional sports complex in Luzhniki.

The initiative to create a new sports palace in Moscow was put forward in 2015 by the president of the All-Russian Federation of Rhythmic Gymnastics, head coach of the Russian national team Irina Viner-Usmanova.

A plan of land in Luzhniki was allocated by the Moscow authorities. Thanks to the fact that the well-known businessman Alisher Usmanov volunteered to finance the construction, the implementation of the project was rapid. And the volume of investments amounted to around 3 billion rubles. Construction began in May 2017 and was generally completed by the end of 2018.

Metropolis participated in the development of the project in terms of structural solutions and internal engineering systems, as well as coordinated the pool of participants, including architects, designers, technologists, event and competition organizers. “A distinctive feature of the project is its cross-platform nature in the execution of the model and drawings. To ensure joint one-time work and coordination of the project, solutions were developed to integrate various specialized software systems into a single BIM model, taking into account the work of about 30 design departments", says Denis Dubinin.

An important point in the design of the engineering sections was the ventilation of the main arena due to the strictly limited air mobility in the central part of the carpet, so that the gymnastic ribbons did not sway during the exercises. To create the correct microclimate, the CFD mathematical modeling system was used. It is a modern tool for checking design engineering solutions for compliance with a functional task. With a large audience and the active use of electrical appliances, warm convective currents, zones with increased air temperature and CO2 content are formed.

Based on the analysis of CFD modeling in the main hall, air exchange was increased by 50%, supply and exhaust devices were redistributed, and different supply air temperatures were set in different zones - they can be controlled independently of each other. This minimized the thermal pressure in the central part of the arena, which significantly reduced air mobility, as well as ensured a comfortable indoor temperature and a satisfactory oxygen concentration in the air.
