Community

A sauna is best enjoyed together. This may be the reason why sauna community culture has been rising in Scandinavia the last few years. People are putting their forces together in order to finance, build and share hothouses all along the shore.

The neighborhood community on Nesodden peninsula, a short ferry ride from the Norwegian capital, Oslo, wanted to increase their already growing number of common saunas.

They wanted an eco-friendly and social sauna with a breathtaking view. In this case Oslo Works has designed a Hotspot that really takes care of that.   

Rules

Constructing a sauna has very few rules.

It needs to be fairly insulated in order to heat up without using too much energy. It needs access to cooling water (or snow), and it needs a heating device. The rest is up to imagination and building permits.

Oslo Works wanted to minimize the climate footprint, as well as the visual dominance and maintenance requirements. Hence, the cabin was constructed of massive wood modules and clad with burnt and oiled ore pine shingles. The modules could easily be transported to the not so accessible lot on the edge of the smooth seaside rock.

Moduls

This version of the sauna concept consists of two parts, divided by an open narrow passage towards the water and the bathing ladder.

To the right, a section with two small changing rooms and storage for necessities. To the left, a hot room with a wood fired oven, a rounded, socially inviting back wall, and a panoramic window towards the big city skyline.

Hotspot is a basic module that can be extended with several add-ons, such as diving board, shower, roof terrace, solar cell panels or connected to other Hotspots in a row.

Online

The freezing cold Scandinavian weather conditions that make the sauna experience on the Norwegian shore, is of course optional. Nevertheless, it is quite easy to imagine this hotspot in warmer climates.

 The hotspot sauna can be booked online from summer 2024.

Pavilion in the park

The swimming pool Noorderparkbad in Amsterdam is a free-standing building with an airy appearance that invites the public to step inside. By focusing on easing the transition between landscape and building and breaking down the typically large scale of a pool accommodation, Noorderparkbad is emphasized as a pavilion in the park.

The softly shaped volumes and curved rain curtain are the mediators between building and park. Two stacked volumes determine the shape of the building. By moving the upper volume to the rear the building blends well with the scale of the park as well as the residential area. In addition, the setback enables the penetration of daylight deep into the building.

Wavy rain curtain

The wavy rain curtain is the most striking element of the Noorderparkbad. Primarily an educational element, it communicates how closely the swimming pool is connected to water.

On a rainy day, the water flows like a waterfall trickling down the curtain and lets the visitor see how rainwater becomes bathing water.

On sunny days the curtain shimmers like a congealed cascade, while on wintry days the ice crystals transform the building into an ice palace. Also, the curtain theatrically marks the entrances to the pool: it is pulled up and guides the visitor into the building.

Family pool

The Noorderparkbad is the new public family pool for the north of Amsterdam and will serve an important social function. The traditional theme of a bathhouse as a meeting place for the neighborhood is reflected in the atmosphere of the interior. Intimate enclosed spaces alternate with high ceilings and skylights.

The wooden rhomboid roof construction and finishes of floor, ceiling and wall in traditional materials lends the building a warm atmosphere.

Sustainable design

The ambitions concerning a sustainable design for the Noorderparkbad are very high and already taken into account from the layout of the floor plan.

Acting like a warm blanket, the secondary functions are therefore wrapped around the three halls of the various pools, which are heated to high temperatures.

Only the south facing elevations of these halls have no climate buffer, allowing the sun to heat the space and visitors to enjoy the beautiful view over the park.

Water Factory Szczecin

Everything is in flow

The Water Factory Szczecin combines sport, leisure, education and entertainment, as well as innovation, functionality and aesthetics – all in a most remarkable way.

The Couch by MVRDVPhoto: ©Daria Scagliola & Stijn Brakkee

Fabryka Wody

The Water Factory brings a fantastic range of sports and leisure activities to the Polish city of Szczecin (formerly Stettin, population 400,000) – and is much more than just a swimming pool.

The attractions at the Water Factory Szczecin (Fabryka Wody) include 21 swimming pools, eleven water slides, a huge wellness area, a beach with volleyball court and an amphitheatre that can be transformed into an ice rink in winter. This is the sporting area.

On the other side, the western wing of the 17,000 m² area is dedicated to the Water Factory Education Centre. Here you will find a wealth of knowledge and entertainment on the subject of water and its importance with regard to our lives and our civilisation.

Water features and desert sauna

The water features and swimming pools at Water Factory Szczecin cover an area of more than 2,400 m², including a complete indoor pool complete with sports basin, relaxation area including infinity pool, saltwater pool, outdoor pool, paddling pool for children and a VIP area with cinema screen.

The wellness area comprises 18 themed saunas in their very own worlds. These include a desert sauna, a paradise island, a volcanic sauna, rose or beer baths, and a snow grotto.

Megalopoolis

A connecting promenade with cascading watercourses, open spaces, entrances and plenty of places to spend time wends its way between the two parts of the building.

The indoor and outdoor pools, saunas, outdoor areas, caves, slides and climbing wall are organised and structured by an architecture that makes water and the nearby Oder river its theme and uses state-of-the-art technology.

Layout by Andrzej Truszczyński and Pawel Kobierzewski (TKHolding), swimming pools by Myrtha Pools.

Szczecin and water

Built on a five-hectare terrain, the three-storey complex was constructed on the site of the historic “Gontynka” bathing area. The central entrance hall is the focal point of the Water Factory Szczecin (Fabryka Wody). It connects the pool complex with the Education Centre and creates a multi-layered, dynamic and public space.

Symbolising the theme of water and the historical and economic importance of the Oder for the city of Szczecin, the design makes use of several flowing lines and a winding façade and takes advantage of the terrain’s natural gradient.

Networks and peepholes

The Water Factory Education Centre consists of six thematic blocks: Space, Climate, Ocean, Humans, Water Civilisation and Water Technology, all of which make use of digital media and networks. Visitors can launch a ship here or make rainbows, water swirls, and clouds.

The laboratories and having the opportunity to go underneath the swimming pools and look through peepholes to gain insight into water technology and treatment, as well as energy generation and supply, are equally exciting.

Amenities and sunshine

The Water Factory Szczecin also boasts the latest equipment and building technology. This includes not only state-of-the-art and time-honoured swimming pool technology, but also water technology and the use of renewable energy. This makes it possible to sunbathe in both the indoor swimming pool and the wellness area – thanks to skylights made of ETFE film, which let UV radiation (natural sunlight) into the interior of the building.

Outstanding

The Water Factory Szczecin combines innovation, functionality and aesthetics in a remarkable way and has therefore quite rightly already received several awards.

Alsterschwimmhalle

Alsterschwimmhalle Hamburg

Swimming opera

gmp

50 years after its inauguration, the Alster swimming pool (Alsterschwimmhalle) was extensively renovated, remodelled and extended.

The Couch by MVRDVPhoto: ©Daria Scagliola & Stijn Brakkee

Like Sydney

The ceremonial reopening of the Alsterschwimmhalle will take place on November 24, 2023. As one of Europe’s largest shell buildings, the indoor swimming pool, designed by architects Horst Niessen, Rolf Störmer, Walter Neuhäusser, and the engineer Jörg Schlaich, is an outstanding example of Hamburg’s post-war architecture.

At the time, the concrete shell roof, which consists of two hyperbolic paraboloid shells carried by three supports, reminded Hamburg’s citizens of the Sydney Opera House – and since then, has been lovingly nicknamed “Schwimmoper” (“Swimming Opera”). The spectacular shell roof, the enormous interior with the 50-meter pool, and the facade construction were retained. At the same time, the sports facilities were comprehensively redesigned for the first time and supplemented with contemporary additions.

Under monument protection

Originally, the Alsterschwimmhalle was constructed as a competition venue but over time it became a leisure pool for the general public. Despite its 400,000 visitors in 2014, for financial reasons closure of the pool, demolition, and construction of a new modern building was under discussion.

In cooperation with schlaich bergermann partner (sbp), gmp developed a feasibility study that became the basis for the decision to retain and refurbish the building.

A key element in this decision was the fact that the spectacular roof had been given listed status. Covering a floor area of 4,500 square meters, the roof – which is only 8 centimeters thick and held up by three diagonal support struts – soars to a height of 24 meters at its tips. Two of the three support points are linked via a tie beam beneath the swimming pool. With spans of up to 96 meters, the roof is still one of the largest of its kind in the world.

More water surface than before

The 50-meter pool, the 10-meter diving tower, and the so-called “fitness cube” on the east side have been retained with very few modifications. However, the old, now barely used tiered seating beside the pool was dismantled to provide space for a new, separate diving pool.

 Furthermore, the extension building to the north was demolished and replaced by a new one- to two-story building. This accommodates a new 25-meter swimming pool, a training pool, a barrier-free entrance area, as well as changing rooms, fitness facilities, and saunas.

Overall, the existing water surface area has been increased by a quarter; just over half of the total internal area has been rebuilt. A new forecourt has been created in front of the main entrance.

Preserved identity

The original aluminum trussed columns of the glass facade have been retained. gmp, sbp, and Implenia Fassadentechnik also developed a new building-code-compliant telescopic piston support system that forms a flexible connection between facade and roof; this makes it possible to compensate for oscillating movement of the roof shell.

The surfaces of the retained building components were restored to recreate the original face concrete appearance, using elaborate restoration techniques, or returned to the original former color scheme. Construction elements such as the historic acoustic tiles were restored and reinstalled.

The architectural identity of the indoor pool facility was retained whilst striking a balance between preservation, functional redesign, and meeting changes in user demand, thus ensuring the pool’s long-term functionality and operation.

Aquaris Borstel

THE RENOVATION OF THE AQUARIS IN BORSTEL

Old dogs, new tricks

HOW A SMALL COMMUNITY IN LOWER SAXONY RENOVATED ITS SWIMMING POOL AND LED THE WAY IN THE PROCESS.

Damage such as defective pipelines is often the reason for closures of municipal baths, especially given the already enormous financial burdens caused by Covid-19 and the war in Ukraine.

Smaller communities in particular are heavily burdened by the operating costs of their baths. If there is also damage, closure is often the result.

The Samtgemeinde Siedenburg, the smallest Samtgemeinde (association of municipalities) in the Diepholz district with almost 4,600 inhabitants, boldly took a different path: after a construction period of about one and a half years, the “Aquaris” was reopened in November 2022. The result of this pioneering project was not decommissioning and demolition, but the cost- and quality-conscious renovation of the baths.

The already high operating costs of the Aquaris Borstel (especially for water, chemicals and heating costs) became more and more problematic due to the daily water loss. Therefore, the Samtgemeinde Siedenburg – an association of five municipalities from the Lower Saxon district of Diepholz, including Borstel – commissioned an expert opinion in 2019.

This report came to the conclusion that the heavy water losses were caused by defective pipelines. This is a common problem in older baths. Damage such as this is often the reason for closures of municipal baths, especially in view of the already enormous financial burdens caused by Covid-19 and the war in Ukraine.

“YOU CAN’T TEACH AN OLD DOG NEW TRICKS.”

The increasing number of closures of baths is also dangerous from a social point of view. Around 20 percent of German children between the ages of six and ten could not swim in 2022. This was the finding of a Forsa survey for the Deutsche Lebens-Rettungs-Gesellschaft (DLRG). In 2017, the proportion of non-swimmers of primary school age was at just ten percent. Those who do not learn to swim as children will have a much harder time later on.

In addition, our swimming pools are important social meeting places for all age groups.

So the Samtgemeinde’s council reacted boldly and awarded the renovation contract to Deye Consulting in Hatten.

THE TECHNOLOGY USED IS CALLED “RENOVACTION” AND IS SUCCESSFULLY USED BY MYRTHA POOLS FOR THE RENOVATION AND RENEWAL OF EXISTING BATHS

The focus of the modernisation was the new pool. The worn–out ceramic pool was replaced by a stainless steel pool with foiling – a proven and unbeatably efficient system. The technology behind it is called “RenovAction” and is successfully used by Myrtha Pools for the renovation and renewal of existing baths. This modular approach is suitable for the renovation of individual areas such as walls, overflow gutters or floors, but also for the renovation of the entire pool structure, as was necessary in Borstel.

Another highlight of the Myrtha technique is “Softwalk”, a soft, closed-pore foam pad which has been inserted on the pool floor under the PVC coating and makes movement through the water noticeably more pleasant and safe.

The swimming area received a wide staircase; the water depth in the access area was reduced from 1.55 m to 1.20 m. Both of these measures make access noticeably easier. This has been very well received, especially among the older age groups, and makes it possible to adapt the usage concept of the Aquaris Borstel to all age groups – and therefore to significantly improve the utilisation of the baths.

The pool is now 16.66 m long and eight metres wide. Although the area is slightly larger overall, the reduced depth results in a volume of 240 m3, which is an energy-saving 20 m3 less than before the renovation.

WITH INCREASING CAPACITY UTILISATION, THE REQUIREMENTS FOR WATER TECHNOLOGY ARE ALSO INCREASING.

Before the renovation, the water quality was guaranteed by the large make-up quantity of drinking water. This is no longer necessary, and the drinking water and the lost thermal energy are now saved.

The water treatment of the baths has been brought up to the state of the art, so that the water quality is guaranteed even at the higher load.

The measuring water, pure water and surge water pipes have been completely renovated. Now there are energy-efficient pumps and a control technology which minimises operating costs. The facilities in the technical room have been fundamentally modernised. Here there is now the most modern technology in the area.

Since the pipes in other parts of the building also proved to be in need of renovation, the work had to be expanded. The entire sanitary and shower area has been newly planned and modernly designed. In addition, the supply lines were also renovated here.

A SMALL BATHS, IN OTHER WORDS, WHICH, THANKS TO PLANNING SKILLS AND SUSTAINABLE MODULAR CONSTRUCTION, MAKES A VITAL CONTRIBUTION TO BORSTEL’S CHILDREN BEING ABLE TO LEARN TO SWIM.

The total costs amounted to around 1.2 million euros. This includes funding in the amount of €480,000.

For this very modest sum in bathroom construction, the Aquaris in Borstel received a generation-appropriate, blue stainless-steel pool with a foil floor in the most modern modular design, a completely new technical room with sustainable equipment, as well as new showers and changing rooms.

The Aquaris Borstel is not a sports and competition pool, but it is record-breaking in terms of its usefulness and sustainability. 20 sports courses are already taking place here; in addition, schools, kindergartens, the community college and out-of-town clubs have reserved bathing times.

A new addition to the programme is an offer for toddlers from twelve months. A small baths which, thanks to planning skills and sustainable modular construction, reflects on its tasks of public services and makes a vital contribution to the fact that at least Borstel’s children can learn to swim.

Exemplary!

Lalandia

Lalandia Søndervig

Swim & sleep

Water, play and well-being

The combination of water ark and holiday resort has proved to be extremely successful.

In June 2022, the third Lalandia holiday resort opened – Lalandia in Søndervig on the west coast of Jutland. The catchy name ‘Lalandia’ is Latin for Lolland, the island in southern Denmark where the first Lalandia opened in 1988.

The concept has proved to be extremely successful, with visitor numbers approaching 1.5 million guests a year for the three resorts. Most of the guests come from Denmark, Norway, Sweden and Germany.

Lalandia has a climate-friendly energy supply with solar cells on the roof and power supplied from Danish wind turbines.

In addition to being a fabulous water park, Lalandia is also a recreational centre.

In the tropical water park – the Aquadome – the water is always 28°C and the air is 30°C. The gigantic hall contains an impressive 14 slides and a wave pool for surfers. You can always get tips and advice from surf instructors and help with getting the rubber raft to hurtle down the large Tornado tube slide, which like some of the other slides also weaves its way outside the actual building.

Several smaller pools and activities are designed for the youngest children, who can run around in a safe environment where trained lifeguards keep a close eye on everyone.

In addition to being a fabulous water park, Lalandia is also a recreational centre, with an amusement arcade, padel courts, shopping, an outdoor pool area and, not least, several different eateries. A lot of thought has gone into creating a relaxed and informal atmosphere.
In a way, Lalandia is like an indoor festival site with stalls and activities connected by winding paths.

1,600 guests at the same time require high capacity and superior acoustics

The resort can accommodate up to 1,600 guests at the same time, which requires high capacity and superior acoustics. The activities in the Aquadome are particularly demanding soundwise, because water splashing against tiles and waves always generate a lot of noise.

To solve the problem, sections of Troldtekt acoustic panels have been installed on the large walls, and also on the ceiling above the children’s pool.

In the restaurants, the acoustics are effectively dampened with Troldtekt acoustic panels, which are also used in many of the secondary areas, such as in the changing rooms etc.

In addition to the centre itself, Lalandia also rents out 464 holiday homes, all equipped with Troldtekt ceilings.

In addition to the centre itself, Lalandia also rents out 464 holiday homes, which have been built adjacent to the large hall. They are located in a flat terrain just north of the activities, so holiday guests only have a short distance to walk to the attractions, the town of Søndervig and the North Sea, which lies only 500 metres away.
The houses vary in terms of both their size and shape, but Troldtekt acoustic panels have been installed on all the ceilings. In total, approx. 24,000 square metres of Troldtekt have been supplied, either as roof cassettes or panels for installation with screws.

Cradle to Cradle

From silver to gold

Cradle to Cradle

The vision behind Cradle to Cradle is a world in which manufacturers design their products for a circular economy.

Advancing to Gold level is primarily the result of Troldtekt introducing new paint recipes in production.

After ten years of Cradle to Cradle certification at Silver level, the entire range of Troldtekt cement-bonded wood wool acoustic solutions has now advanced to Gold level. The vision behind Cradle to Cradle is a world in which manufacturers design their products for a circular economy – in other words where the materials can be reintroduced in new cycles.

Advancing to Gold level is primarily the result of Troldtekt introducing new paint recipes in production.

The switch to the new paint type means that Troldtekt is moving up two levels – from Silver to Platinum – within material health, which is one of the five categories of criteria counting towards Cradle to Cradle certification. And as Troldtekt is already at Gold or Platinum level in the other four categories, it triggers overall certification at Gold level. The certification is officially valid from 1 March 2022.

“It’s not just a small corner of our range that is now Cradle to Cradle-certified at Gold level – it is the entire range of Troldtekt cement-bonded wood wool products.”
Tina Snedker Kristensen

“More than a decade ago, we chose to base our business strategy on the Cradle to Cradle principles. Since then, we have optimised our production by switching to renewable energy, by systematically recycling waste and much more. Material health, and specifically the preservatives in the paint, have been the only barrier to achieving Gold certification. Therefore, the new paint recipes represent quite a milestone for us,” says Tina Snedker Kristensen, Head of Sustainability and Communications at Troldtekt A/S.
“It’s not just a small corner of our range that is now Cradle to Cradle-certified at Gold level – it is the entire range of Troldtekt cement-bonded wood wool products in either natural wood or painted in our standard colours white, grey and black. The certification also covers our design series and our brand new carbon-negative acoustic panels based on the cement type FUTURECEM™,” she adds.
In practice, the systematic work with Cradle to Cradle means that Troldtekt possesses in-depth knowledge of all the ingredients in the acoustic panels, right down to 100 parts per million. Analyses have shown that the panels do not contain any substances which are harmful to humans or the environment. Healthy ingredients are a prerequisite for being able to reintroduce products into new biological and technical cycles. And healthy cycles are the backbone of the circular economy.

“After lengthy discussions with our paint suppliers, we’ve now arrived at a new and durable paint recipe which contains no harmful biocides.”
Vibeke Pedersen

The preservatives – biocides – in the paint for the acoustic panels have so far stood in the way of achieving Cradle to Cradle certification at Gold level. However, recipes have now been successfully developed that use newer and more sustainable preservation technology.

“Preservatives are necessary to avoid having to discard large quantities of paint due to spoiling and frequent colour changes in production.” explains Vibeke Pedersen, Head of Engineering Department at Troldtekt A/S.

“Since installing our new paint facility in 2016, we have collected and recycled excess paint – or ‘overspray’ as it is called – from our spray booths, which has cut the amount of paint we waste by 70 per cent.”
“If we removed the preservatives, we would no longer be able to use the overspray due to microbial attacks. And this would result in total waste of approx. 200,000 litres of paint a year.”
“After lengthy discussions with our paint suppliers, we’ve now arrived at a new and durable paint recipe which contains no harmful biocides. However, the new paint is still sufficiently durable for the overspray to be recycled. This has required product development and extensive testing of the recipes in our production. So, a lot of hard work has paved the way for our certification at Gold level,” she says.

The 18,000m² of new campus buildings include a 300-room student residence, the new headquarters of the SDA Bocconi School of Management, and the new multi-level athletic centre. The new centre includes fitness spaces, two basketball and volleyball gymnasiums and an elevated running track.

Then, of course, there’s the water. As a magnificent main feature of the centre, Myrtha Pools has installed a 25 m training pool and a fully equipped 50 m Olympic pool. And, Myrtha Wellness has been responsible for outfitting the Virgin Active Wellness Centre.

The gorgeous, well-equipped pool meets all FINA competition standards and is ideal for training and competition.

The jewel of the sports facility is the new Myrtha aquatic centre, open to both students and the community. Visible from the hall of the building, the view from above highlights the beauty of the Olympic pool, equipped with Myrtha’s split, movable bulkhead.

The two-piece bulkhead makes it simple to configure the pool for multiple uses. The gorgeous, well-equipped pool meets all FINA competition standards and is ideal for training and competition in swimming, water polo, and artistic swimming.

In addition to the Olympic competition pool, the facility also includes a Myrtha 25 m training pool, perfect for lane swimming, Aquagym, Aquabike and other aquatic fun; and it’s also home to a wellness centre that includes a steam bath, sauna, Jacuzzi and emotional showers provided by Myrtha Wellness.

In addition to all the technical refinements, the swimming hall is a real eye-catcher.

The Olympic Pool, measuring in at 51.5 m (50 m, plus the width of the bulkhead), is equipped with state-of-the-art technologies including an advanced lighting system and the AngelEye underwater drowning detection system.

Additionally, two lanes in the competition pool have been equipped with the Virtual Trainer, an intelligent LED system that allows swimmers to follow precisely programmed training speeds set by their coaches.

In addition to all the technical refinements, the swimming hall is a real eye-catcher. Its beauty can already be admired from the entrance level above.

The Bocconi Sport Center already is the object of admiration at the Università Bocconi. All over Europe.

The new Bocconi campus was created with commitment to sustainability. Myrtha’s modular stainless-steel pool system reduces CO2 emissions by up to 50% compared to a traditional concrete tank. And Myrtha’s many environmental advantages are evidenced by contributions to international sustainability and energy efficiency certifications like LEED, BREEAM and Green Star.

In the case of the Bocconi campus, the Myrtha Research & Development team went to work on a plan to reduce water consumption in the new facility. An algorithm was developed that analyses water quality data as well as the number of accesses (or, swimmers), and can pro-actively reduce water consumption while maintaining optimal water quality.

The Bocconi Sport Center is open to both students and the public. Its architectural, economic and ecological quality have turned it into an attraction that Università Bocconi is already being envied for. All over Europe.

Rheinblick 741

Rheinblick 741 in Düsseldorf

Nomen est Omen

A pioneering swimming venue and meeting place for leisure, sports and politics on the banks of the Rhine.

The barrier-free building also plays host to a district administration office, including rooms for meetings and conferences for district representatives.

In cooperation with the Bädergesellschaft Düsseldorf mbH, the North Rhine-Westphalian state capital of Düsseldorf has realized a pioneering swimming venue and meeting place for leisure, sports and politics on the banks of the Rhine.

With its shape and silver-grey facade, the organic building complex is reminiscent of a pebble lying next to the Rhine. It houses an indoor pool, a physiotherapy practice, a fitness room for use by clubs and for physiotherapy as well as an event room for up to 200 people.

The new multifunctional and completely barrier-free building also plays host to a district administration office, including rooms for meetings and conferences for district representatives. Next to the complex there is a large area with 131 parking spaces as well as bicycle parking spaces. And right across from that there is a 50 by 70 metre football training pitch.

The swimming area includes a 25-m pool with diving towers, a separate 15 × 8 metre teaching and lesson pool with an adjustable floor and a playfully designed children’s splash area.

“Rheinblick 741 – Begegnung am Wasser” is the only indoor pool in Düsseldorf that offers swimmers a view of the Rhine.

Thanks to the large windows, the interior is flooded with daylight.

The swimming area includes a 25-metre pool with diving towers, a separate 15 × 8 metre teaching and lesson pool with an adjustable floor, a warm water pool and a playfully designed children’s splash area with many colourful water toys. One highlight here is the “Miniature Rhine”, which flows through the area and can be dammed up.

 

Around the lesson pool, there is a long stone bench from which all areas are visible.

Particularly eye-catching are the triangular Troldtekt ceiling panels seemingly reflecting the surface of the water.

In the children’s area, turquoise mosaic tiles combined with brown floor tiles and brightly coloured walls create a friendly atmosphere. In the swimming area, large brown floor tiles are paired with brown mosaic tiles, creating a warm contrast to the bright walls.

Particularly eye-catching and an important design element are the triangular Troldtekt ceiling panels that have been installed, seemingly reflecting the surface of the water.

Troldtekt is cement-bonded wood wool panels that ensure good acoustics in any room. The acoustic panels are manufactured using certified wood, which is a 100 per cent natural material, and cement, which is extracted from Danish mineral resources.  

This provides a healthy and strong material with unique sound absorbing properties.

The swimming pool of the future

The swimming pool of the future

Games. Sport. Recreation.

These trends cover a wide range of aspects that impact on architecture – from economics and digital features to new usage patterns.

IAKS has compiled a report on a number of trends in the swimming centres and outdoor baths of the future.

Swimming and water exercise are popular activities among all ages and at all skill levels. We also use swimming centres to relax – or to be active with our families. The varying usage scenarios place demands on form and function when developers, architects and builders have to jointly arrive at the perfect design.

In a report, the German International Association for Sports and Leisure Facilities (IAKS) NGO listed trends in future swimming centres. The 16 trends can be useful to keep in mind – right from the drawing board stage.

These trends cover a wide range of aspects that impact on architecture – from economics and digital features to new usage patterns.

Swimming is popular

Blurred boundaries between work and leisure are making individual, flexible activities such as swimming, running and cycling increasingly popular. This entails a need for better access to swimming pools and extended opening hours.

Accessibility is not only about focusing on users with physical disabilities. Changes in demographics and ethnic diversity also place special demands on swimming centres.

A lifelong healthy lifestyle

Exercise in water helps fulfil the desire to lead a healthy life at any stage of life. An increasing number of seniors are demanding good exercise pools. Since fewer parents are teaching their children to swim, there is also a need for teaching pools – ideally with an adjustable/movable floor.

Wellness is gaining ground

The combination of sport and relaxation has become more popular. It is therefore a good idea to complement the classic competition and exercise pools with wellness facilities such as spas, saunas, Turkish baths, treatment facilities and lounge zones.

Fun for children and families

Families with children are an important target group for swimming centres. It is therefore important to have facilities that support play and give children a good introduction to the water.

Designing for inclusivity

Accessibility is not only about focusing on users with physical disabilities. Changes in demographics and ethnic diversity also place special demands on swimming centres. Everything from stairs and changing rooms to signs and lighting can have an impact. It is important to involve all key stakeholders early in the design phase.

Sustainability and carbon footprint also play a major role in the construction of swimming centres.

Pools as places for socialising

Leisure activities are also a hub for socialising. It is important to encourage young people to meet at the swimming centres. And again, it is important to involve users in the design process.

Sustainable and healthy facilities

Sustainability and carbon footprint also play a major role in the construction of swimming centres. Measures that save water, recover heat, harness solar energy and minimise waste must be in focus. Ideas about a healthy lifestyle also place demands on technical conditions in relation to things like water and air quality.

Safe and secure pools

The risk of ‘anti-social behaviour’ may necessitate video surveillance above and below the water, and increased use of security personnel at swimming centres.

Competing demands on public finances

Government investments have to be prioritised. To secure funding for a swimming centre, the parties behind it have to be able to highlight the social value of the project. Partnerships with non-profit organisations or private companies may be a model for financing.

A swimming centre can be combined with a sports hall, a gym or even a library.

Improving economics

Swimming centres should ideally be operated without incurring losses. A swimming centre can be combined with a sports hall, a gym or even – as seen in England – a library. Achieve economies of scale by managing indoor and outdoor facilities in the same region in a single unit.

Private sector focuses on profitable cases

It can be difficult for municipalities to balance their budgets. Private players often invest in the most profitable business cases, such as gyms and large wellness centres. This can leave municipalities with the less attractive ones. When this happens, it is important to focus on the social rather than the economic benefits.

Digital transformation

Digital features also have an impact on the architecture of new swimming centres. The ability to track your performance in the water, water slides with virtual reality and cash-free payments are examples. In terms of the actual construction process, building information modelling (BIM) will become increasingly significant.

User expectations are growing

People are travelling more and experiencing more online. This can increase expectations of user experiences – including when visiting the swimming centre. It is therefore important that new swimming centres meet current international standards.

Good design is essential to ensuring a good user experience – so that visitors keep coming back.

Scarcity of space

Given the shortage of space in many cities, swimming centres need to serve multiple purposes. For example, an outdoor baths in summer could double as a skating rink in winter.

Fight for talent

When the economy is healthy, it can be difficult to find enough skilled staff for swimming centres and other sports facilities. Internal training can be one way to attract and retain employees. Technological solutions may in some cases be able to replace employees.

Good design

As evidenced by the trends outlined above, designing and building a new swimming centre is a complex task. But it is important to do this well. Good design is essential to ensuring a good user experience – so that visitors keep coming back.

Therme Lindau

Therme Lindau

All in

Minimalist charm and unique design, promising extensive bathing fun and maximum relaxation.

Therme Lindau offers a unique wellness and bathing landscape spread over 13,000 m² and including a spacious outdoor area with a spectacular view of both water and mountains.

Designed by 4a Architekten GmbH from Stuttgart (Germany) and nestled in the beautiful landscape between Eichwald and Lake Constance, the spa in Lindau is located on the shore of Lake Constance.

The elongated new building features expansive windows and a wood/concrete facade, inviting you to linger in its unique wellness and bathing landscape spread over 13,000 square metres and including a spacious outdoor area with a spectacular view of both water and mountains.

The elongated building was aligned with the edge of the shore. The ground floor features the various areas of experience. Above this, gently embedded in the landscape between Eichwald and Lake Constance, lies the second level.

The water attractions in a total of six different pools include a lazy river, a wild stream complete with tube water slide, a water cave for children and a giant whirlpool for up to 30 people.

The spa features a family and sport pool, including a 25-metre Olympic swimming pool and an expansive area boasting thermal baths, a wellness centre and saunas.

An elegant and inviting dining area with a pool bar overlooking the lake, a fitness area as well as a spa area that can be booked for private use complete the premium wellness offer.

The water attractions in a total of six different pools include massage loungers, bubble seats, neck jets, a lazy river, a 40-degree spring pool, a wild stream complete with tube water slide, a water playground, a water cave for children and a giant whirlpool for up to 30 people. There are also diving towers, an intensive salt water floating pool with underwater lighting as well as an underwater concert hall.

The Troldtekt acoustic panels absorb sound and go well with the overall design.

The minimalist exposed concrete design combined with wood and stone elements is elegant and expressive. Large, partially sloping concrete structures subdivide the areas on the ground floor, creating striking spatial scenarios.

The building’s open ceiling design allows even more light to enter in addition to the large windows.

The Troldtekt acoustic panels absorb sound and go well with the overall design, thus fulfilling a key role. Adding colourful highlights in green, red and black, they contrast beautifully with the light walls and floor.

Troldtekt Accoustic Ceiling

Acoustic ceilings in swimming pools

Shhh.

To be successful in offering relaxation, the quality of the building materials used along with attractive facilities is crucial.

Ceiling and walls clad with Troldtekt acoustic panels effectively absorb the sounds of splashing, shouting and playing, thus contributing to pleasant acoustics in swimming centres.

Escape from everyday life and experience relaxing moments. This is what today’s guests expect from an indoor swimming pool. To offer this, not only attractive features are required – the quality of the building materials used also determines the well-being of the guests and thus the success of the pool.

Ceiling and walls clad with Troldtekt acoustic panels effectively absorb the sounds of splashing, shouting and playing, thus contributing to pleasant acoustics in swimming centres.

Cement-bonded wood wool panels are also durable, with a natural resistance to moisture. The flexible design options also offer considerable architectural freedom.

Choosing materials is a particularly challenging process for architects designing swimming centres. Of course, the materials have to aesthetically match the architectural idiom. But a number of functional requirements also need addressing.

Swimming centres are usually large spaces, high-ceilinged and with many glass or concrete surfaces. In combination with the excited shrieks of children having fun in the water, this calls for acoustically exacting solutions. It is therefore important that the large ceiling and wall surfaces are clad with materials that have a high absorption coefficient – so they effectively soak up the sounds.

Environments with constant high humidity also place additional demands on the strength and moisture tolerance of the materials. Finally, the expansive walls often need a very carefully conceived visual design.

Troldtekt panels are chosen for many swimming centres – and outdoor baths – because the natural advantages of the cement-bonded wood wool panels perfectly match the requirements. You can read about five reasons why Troldtekt is an ideal choice below.

Cement-bonded wood wool retains the essential qualities of the components used to produce it – the strength of cement and the natural breathability of wood.

Superior acoustics

The open structure of Troldtekt acoustic panels absorbs sound effectively. The result is shorter reverberation times, minimising unpleasant noise – in the swimming pool areas and in the associated facilities (changing rooms, café etc.).

Natural strength

Cement-bonded wood wool retains the essential qualities of the components used to produce it – the strength of cement and the natural breathability of wood. Troldtekt acoustic panels are moisture-tolerant and therefore extremely suitable as acoustic ceilings in wet rooms. The panels cannot rot and do not attract fungal growth or other microorganisms.

The Danish Technological Institute has documented that Troldtekt acoustic panels are suitable for installing in rooms with:

  • moisture levels of up to 98 per cent (+/- 2 per cent)
  • high temperatures of up to at least 40 degrees.

Troldtekt has thus achieved the highest CE marking level (D) for water resistance.

The documentation shows that Troldtekt is a robust choice for even the most humid and warm rooms such as swimming pools, shower rooms and wellness departments.

>> Read more about natural strength

Effective fireproofing

Wood alone is an organic and flammable material, but every single wood fibre in a Troldtekt panel is encapsulated and protected by cement. Troldtekt panels are therefore fireproof without the use of any fire retardant or dangerous chemicals.

Troldtekt acoustic panels are fire classified under European standard EN 13501. Troldtekt acoustic panels are classified as B-s1,d0, which denotes the material’s reaction to fire. In practice, this means that Troldtekt panels are only weakly combustible and weakly heat and smoke-emitting.

>> Read more about effective fire protection

Troldtekt panels can be used to create a unique look on large ceiling and wall surfaces, adding to the whole as sound-absorbing design elements.

Flexible design

Troldtekt panels offer a number of different design options. Through special installation, colours or CNC machining, the panels can be used to create a unique look on large ceiling and wall surfaces, adding to the whole as sound-absorbing design elements.

Troldtekt design solutions come with the same great technical properties as the classic Troldtekt acoustic panels.

>> See the design options

Documented sustainability

Troldtekt is certified in the silver category under the internationally recognised Cradle to Cradle scheme.

The certification was attained in part because the panels contain no substances that are harmful to humans or the environment. They can therefore return to the biological cycle as nutrients, or to a technical cycle as a raw material in cement production.

 

Ramboll has also outlined how Troldtekt specifically contributes points to areas such as total cost of ownership, indoor climate and materials in the leading sustainability certifications – DGNB, LEED and BREEAM.

>> Read more about documented sustainability

Simple installation

Troldtekt panels are installed directly on battens on ceilings and walls or using profile systems such as suspended ceilings – with concealed or visible profiles. When installing the panels, only a few screws are needed per panel. There is no need to use filler or paint after installation.

The Troldtekt series includes specially designed screws that match the panels’ standard colours and structure. If you choose Troldtekt panels in custom colours, we can supply extra paint so you can dab the screws in the same colour.
