Cheering on your favourite sporting team, enjoying outdoor concerts, visiting museums…all aspects of city life which are enhanced by the work of the IEC. Technology advances are improving Energy Efficiency and safety.
Here is an extract from an IEC e-tech article by Peter Feuilherade. You can read the full article here.
A multitude of electrical and electronic systems helps fans enjoy sporting events
Experiencing sporting events live in outdoor or indoor installations is a unique experience. In addition to suitable lighting that has made it possible to hold sporting events both indoors and at night, sports venues have seen the introduction of a variety of electrical and electronic installations that benefit followers by providing a safer environment in which they can enjoy their favourite games and events.
Today’s state-of the art sports venues enhance the experience of fans by providing real-time game updates on giant digital screens and free high-speed Wi-Fi allowing them to share their emotions on social media. But behind the scenes in stadiums, the latest lighting and sensor technologies also play a vital role in making events as compelling, comfortable and safe as possible for spectators who might otherwise choose to watch live sports on widescreen TVs in the comfort of their own homes.
Stadiums increasingly host different types of events, such as sports, concerts and theatre performances. Floodlights and other lighting must be adaptable, enabling the playing arena to be illuminated to specified levels at night or in low light conditions or to provide stage lighting, all the time ensuring glare and light pollution of the local environment are minimal.
Advances in LED (light-emitting diode) technology mean that LED floodlights are now bright enough to be used for illumination purposes on large sports fields. Although they can cost nearly four times as much as traditional metal halide floodlights, they radiate very little heat and last significantly longer. They can be switched on and off instantly, requiring no warm-up period. IEC TC (Technical Committee) 34: Lamps and related equipment, and its SCs (Subcommittees) prepare International Standards for all types of lamps and luminaires used in sports venues.
A number of IEC TCs and SCs prepare International Standards for components and systems in the fields of lighting and sensors.
The TC primarily responsible for drawing up International Standards for lighting is IEC TC 34: Lamps and related equipment. TC 34 includes four SCs which prepare international standards for specific fields: SC 34A – Lamps including LEDs, OLEDs (organic light-emitting diodes) and glow starters, has published over 130 Standards covering, among other things, metal halide lamps and LED lamps; SC 34B – Lamp caps and holders; SC 34C – lamp controlgear, with the focus on controlgear standards for metal halide lamps (square wave operation), fluorescent lamps and LED modules; and SC 34D – luminaires.
IEC TC 47: Semiconductor devices, includes sensors in a number of its publications and SC 47E: Discrete semiconductor devices, prepares International Standards for components used in a variety of sensors.
The scope of TC 76: Optical radiation safety and laser equipment, is to prepare International Standards for equipment incorporating lasers and LEDs. With an emphasis on safety, the scope includes the preparation of standards applying limits to human exposure to optical radiation from artificial sources. These are important in sports venues.
With sports fans tending to be early adopters of new technology, some venues, notably in the US, are experimenting with proximity sensors and beacons, partly for merchandizing applications by sending messages to fans’ smartphones but also to allow them to upgrade their seats.
Attempts to make money from social media notwithstanding, the primary goals in future stadium design for architects, engineers and facility managers alike remain greater safety and energy efficiency.
