Inspirational slides on the use of LTDH in the public space
What would be possible if we had close to an unlimited amount of lukewarm water? After conducting workshops, exploring existing ideas and promote low temperature district heating to the public we ended up with some exiting solutions on LTDH in the public space. We hope that this inspire and help thinking outside the box when reflecting on the additional possibilities when building temperature district heating grids in cities.
In Lund, on an early spring day when the sun is warm, you will see people flock to the south wall of Lund cathedral to eat their lunch or just take a few minutes break in the heat. With the help of low-temperature district heating, there is the opportunity to create more such meeting places. The residual heat can help to warm up walls and associated seating to create life and movement with, for example, lunch grills outdoors even during the colder days of the year.
In many cities, skateparks have become an important meeting place for people of mixed ages, not infrequently in connection with an outdoor gym or other activity areas. In summer, the trails stay dry and nice to ride, but in the fall and winter, wet leaves, puddles and snow can make them inaccessible. With the help of low-temperature district heating, it would be possible to keep the tracks in the skatepark a little heated so that snow melted away and the tracks dried up faster. This could make it possible to go outdoors in winter.
Water play in the middle of autumn? With the help of low-temperature district heating, the water can be heated up to a comfortable temperature for children to splash with, while the ground and seating on the playground surface can be heated a few degrees for adults or sedentary children to relax on. Do you think heated playgrounds seem to be an attractive opportunity, or is it unnecessary?
Imagine a rough day in the late autumn. You have stayed indoors and now you need fresh air. Not far from where you live there is a meeting place for spontaneous sports that is heated a few degrees with low temperature district heating. The place is just warm enough for you to feel comfortable wearing a t-shirt while you are active, and gentle enough to make it comfortable to sit down with a lighter jacket. Could this be a place that you would use with, for example, your friends or family?
Water heated to a comfortable temperature would be possible by means of low-temperature district heating. It could be a heated pool or, as in the example above, a water environment suitable for wading in conjunction with a visit to the park – whatever the season.
Surely it would be nice not to worry about snow and ice slipping on pedestrian and bicycle lines? With low-temperature district heating in the ground it can become a reality! In addition to reducing the risk of fall accidents, it also has other benefits, such as reduced snow removal costs. Perhaps it may also have an increased environmental benefit. For example, would you choose to walk or cycle instead of taking the car if it were snow-free on the walking and cycling roads during the winter?
Are you tired of standing and freezing while waiting for public transport? Imagine a heated bus stop where you can stay warm while waiting for the next bus or tram, something that low temperature district heating can make in a sustainable way. Could this make you choose public transport more often? Would it make your trip more comfortable or is it the same?
