Dancing to Heat a Building

Glasgow club recycles dancers' body heat for energy.
Today's dance article was written by my former boss's daughter, Margaret Fuhrer, in December, after the environmental summit in Scotland. (Her father was a wonderful boss, by the way, and a good sport. His daughter's dance-writing career has roots in her childhood Nutcracker performances in which he gamely played Mother Ginger.)
Fuhrer reports at the New York Times that a club in Glasgow is using the heat from dancers' bodies as alternative energy to power the building.
"At SWG3 — an arts center in Glasgow, Scotland, that hosts some of the city's largest dance parties — tickets for club nights sold briskly during the summer and fall of 2021, before the arrival of the Omicron variant. 'The appetite for these events has been stronger than ever, and it's fueled by the long period of time we were all denied it,' said Andrew Fleming-Brown, SWG3's managing director. 'We've missed that shared body-heat experience, being packed together in a full venue.'
"What if dance-floor catharsis could be good not only for the soul but also for the planet? This month, SWG3 and the geothermal energy consultancy TownRock Energy will begin installing a new renewable heating and cooling system that harnesses the body heat of dancing clubbers. The plan should eventually reduce SWG3's total carbon output by 60 to 70 percent. …
"There is poetry in the idea: the power of dance, made literal. 'Conversations about sustainability can be pretty abstract,' said David Townsend, the founder and chief executive of TownRock. 'But if you can connect it to something people love to do — everyone loves a dance — that can be very meaningful.'
"A mutual friend introduced Townsend and Fleming-Brown in 2019, after Fleming-Brown expressed interest in exploring low-carbon energy systems for SWG3. Townsend, 31, is a regular on the club scene and had been to the location several times. …
" 'Trying to do a geothermal well would have [cost millions],' Townsend said. 'Instead, we thought, why not collect the heat you've already got in your customers and then use the ground to store it?' …
"Dr. Selina Shah, a specialist in dance and sports medicine, said club dance floors can be especially good at creating heat. 'If it's really high-energy music, that generally results in very fast and high-energy movement, so you're looking at a significant level of heat generation — potentially even the equivalent of running,' she said.
"To capture that energy at SWG3, TownRock developed an application for an already widespread technology: the heat pump. … The SWG3 system, called Bodyheat, will cool the space by transferring the heat of dancing clubbers not into the atmosphere, as in conventional cooling, but into 12 boreholes approximately 500 feet deep. The boreholes will turn a large cube of underground rock into a thermal battery, storing the energy so it can be used to supply heat and hot water to the building.
"Development of the system began in 2019. Pandemic shutdowns, and the financial uncertainty that came with them, paused the project for several months. But with their events calendar emptied, SWG3 leadership had time to develop a larger sustainability plan for the building, setting the goal of achieving 'net zero' carbon emissions by 2025. 'That moment allowed us to pause and really assess what's important to us as an organization,' Fleming-Brown said. 'We decided to make it a priority.'
"Bodyheat became a central component of the plan when work on the project resumed in fall 2020. The first phase of installation should be complete by early spring [2022], and will provide heating and cooling to SWG3's two main event spaces. Later phases will offer hot water to the bathrooms and heating to the foyer and art studios. At that point, SWG3 will be able to get rid of its three gas boilers, reducing its annual carbon output by up to 70 metric tons.
"The system is not cheap. … Glasgow's hosting of the 2021 United Nations global climate summit created 'a lot of momentum behind this kind of project,' Fleming-Brown said. A grant from Scotland's Low Carbon Infrastructure Transition Program covered half of the costs for phase one, and a government-backed low interest loan helped with the rest.
Fleming-Brown estimates that savings on energy bills will make the investment recoverable in about five years. …
"Dancing has been used to generate energy before. More than a decade ago, the Dutch company Energy Floors introduced a line of tiles that convert dancers' steps into electricity. Club Watt in Rotterdam installed the tiles to media fanfare in 2008, and they have since been used in hundreds of other projects. …
"Kinetic dance floors make only small quantities of electricity. Bodyheat should have a more meaningful impact on carbon output, though broadly speaking, dancing isn't a very efficient way to make body heat. … Gyms, with their emphasis on aerobic exercise, seem like more obvious fits for projects that harness the work of the body. Townsend mentioned that in addition to capturing body heat, gyms could use equipment like stationary bikes to help generate electricity.
"Dancing may not be the best source of renewable energy, but it has proved important in another way: storytelling. There is something vaguely grim about harvesting heat from gym rats pumping away on treadmills. Energy born of dancing — born of joy — captures the imagination in a different way. …
"To help tell the Bodyheat story to the crowd at SWG3, Fleming-Brown and Townsend are considering ways to illustrate the amount of heat dancers create, perhaps with a large thermometer, or a heat map similar to those used on weather reports."

Footfall generators!
Looks like we'll be dancing in the kitchen for a long time yet. Unfortunately, my kitchen is not hooked to a generator.
The power of dance. Now that is something I have never heard of.
Maybe this concept could be applied to children who love to jump on beds.
