CASE STUDY | FRIEZE FAIR more transparent and congruous, and they are now collapsible, making them easier to store. The team at mstep has also come up with a simple, yet incredibly effective, mechanism for regulating the temperature levels within the tent, as Krstanovic explains. We walk around the tent with 30 thermometer guns, taking readings. If temperatures are too high or low, we use WhatsApp groups to talk to the system operatives, who manually tweak the systems. The biggest swings in temperature are caused by the crowds generated by mega celebrities or otherwise. At the start, people arrive at the same time, bringing in body temperature thats when we really have to start playing around with the system, says Krstanovic, who adds that they look at weather forecasts to predict how temperatures in the tent will change. Its incredible what you can do with manual predictive controls. Even in London, with this conventional single overhead duct system, its really successful. Weve discovered that between 20.5oC and 21.5oC is ideal in London. By measuring and communicating the temperature during the day, our teams keep the tent between this 1.5oC band. You dont need a supersophisticated system to do it just people power. Due to the temporary nature of the fairs, human monitoring and control is most effective, she says. Frieze London also occasionally requires air conditioning including last month as October was mild. Teams of six or seven people are on rotation during the day, says Krstanovic. They dont have to be engineers, but they do need to be conscientious about what they are doing, she says. The tents a bit like a sailboat things go very wrong very quickly. Once temperatures start getting uncomfortable, its really hard to bring them back. You cant let it go its relentless, she adds. Krstanovic believes continual monitoring and system optimising should be happening in all buildings. Around 90% of all buildings have sufficient hardware to do this. Its all easy, but we need building management assistance to help FM [facilities management] teams to operate the systems correctly, she says. Operational carbon is what we building services mstep has to be aware of rising temperatures when crowds gather FRIEZE LONDON mstep has just completed working on Frieze London, which took place from 11-15 October. The heating and cooling strategy at the event in Regents Park is relatively simple compared with the one for LA. The mild conditions in early autumn means a conventional overhead ducting system is used. In London, the tent needs to be pre-heated before the event opens at 10am. Then, depending on the conditions, the heating is turned off, leaving only the ventilation running, unless cooling is required which is was last month. When the sun starts to go down, the heating returns as the event continues until early evening. engineers deal with its not glamorous, but thats where the major opportunities are. By monitoring and controlling buildings properly, we can cut energy consumption by 40%. This will please green-minded celebrities such as DiCaprio and Jane Fonda, who have visited LA Frieze. The 2023 event was deemed a success, with dealers reporting a fruitful fair with a contagious energy. A number of works sold for more than $1m, with Mark Bradfords painting Shall Rest in Honor There topping the sales list at $3.5m. In London last month Damien Hirst sold all 12 of his paintings on show and Tracey Emin sold two paintings with a combined value of over 2m. While buyers snapped up the hottest artists, Krstanovic and her team ensured that everyone was able to appreciate the Frieze fair in optimal environmental conditions.
