IBC facilities continue to go green and become more efficient

The Beijing Games are in the middle of their final week and concluding this week will give everyone involved plenty of time to think about operations, as the next games, the 2024 Summer Olympics, will take place in almost 30 months. This is a unique Olympics for many reasons, including the fact that only eight rights-holding broadcasters have a base of operations at IBC (they represent 38 organizations including their sub-licensees). In Zhangjiakou, five RHBs have facilities at the ZBC, representing 16 organizations. And in both IBCs, OBS has taken steps to be more sustainable, environmentally friendly and efficient.

The IBC of the Beijing Olympics has been reduced to just 30,000 square meters.

At IBC and ZBC, broadcaster offices range from small units with a few desks and computers to much larger broadcast spaces that can include multiple control rooms, television studios, editing rooms, booths off-tube commentary, news production areas and other office rooms, depending on Tomoyo Sato, OBS, Senior Director of Broadcast Services.

OBS Technical Facilities primarily operate from an area called OBS Tech, located within the IBC, which is comprised of the Main Control Room (MCR) Contribution, Distribution and Unilateral (CDU) , the International Transmission MCR, the Commentary Switching Center (CSC), the Archive Video Recording Area and Mixed Area Feed Area, and the Broadcast Data Feed Room (BDF) .

“Additionally, for Beijing 2022, OBS also built two TV towers to provide RHBs with TV studios and stand-ups for their reporting,” Sato explains. “Beijing TV Tower is located opposite the National Bird’s Nest Stadium and the Beijing Medal Plazas. In Zhangjiakou, the TV tower is adjacent to ZBC and faces the National Ski Jumping Center.

Eugenia Sofia Fuenmayor, OBS, Construction Managerstates that as part of its long-term commitment to sustainability, OBS has redesigned the IBC, making optimizing the use of space a priority.

For Beijing 2022, OBS successfully reduced the overall net broadcast footprint from 36,000 square meters to 30,000 square meters by facilitating the integration of the IBC and Main Press Center (MPC) into a single location where two were originally planned. By bringing the IBC and MPC together under one roof, a wide range of facilities and services that would otherwise have to be duplicated will now be shared by press and broadcasters, reducing costs for the OCOG while optimizing operations during the Games.

Centralized Technical Areas (CTAs) in the IBC allow less energy to cool equipment racks because they are located more centrally.

“In order to optimize the broadcast operation, and for the first time in an Olympic Winter Games, OBS has designed a series of Centralized Technical Areas (CTAs) strategically placed within the IBC and ZBC,” explains Fuenmayor. “These areas provide ‘data center’ type services and infrastructure to both OBS and rights-holding broadcasters, allowing broadcasters to retain their technical equipment that receives or sends signals to and from OBS, while saving energy by reducing heat, ventilation and air conditioning (HVAC) and technical energy consumption.”

Fuenmayor adds that the zones are shared between multiple rights-holding broadcasters, making it a more efficient use of space and more profitable for broadcasters.

“Within IBC, OBS has created a better mix of technical areas and office space to help better balance airflow and reduce the amount of heating and cooling needed, thereby reducing energy consumption. energy throughout the facility,” Fuenmayor adds.

For Beijing 2022, taking into account the space needs of the RHBs, OBS has built 12 serviced compartments, six on each level at IBC, and an additional 12 at ZBC spread over one floor.

“An improved modular and pre-engineered system has significantly reduced fit-out times,” says Fuenmayor. “With an innovative, completely clean and dry racking system, OBS was able to reduce the lead time by one and a half months, or around 20%. The prefabricated racking system, based on steel sheet panels, will be reused for the next three editions of the Games, resulting in a significant reduction in construction waste.

Going forward, expect further gains in Paris, as OBS has also incorporated a series of improvements, in view of future editions of the Games, to facilitate the construction of facilities with little or virtually no impact on structures. pre-existing and inherited buildings.
