EDITORIAL
DEAR IAKS MEMBERS, DEAR FRIENDS OF SB,
Sport and leisure buildings use a disproportionate amount of energy compared to other building typologies. Municipalities will often find these buildings at the top with regard to assets requiring a targeted approach to carbon reduction in order to meet their net zero carbon obligations. As the cost of energy continues to increase, reducing energy (and carbon) is also a critical factor in the financial sustainability of operating aquatics facilities.
Whole-life carbon is increasingly becoming a major factor in the design of all new building typologies. Whilst operational carbon is still by far the major consideration in aquatics centres, embodied carbon is becoming a major driver in stadia and arena projects and a significant determinant in the lifespan of leisure buildings.
The consideration as to when to refurbish or build new becomes a really important factor at the outset of a project in terms of both whole life-carbon and functionality. Targets and methodologies will be increasingly important tools to ensure the client, design team and contractor are all aligned on the low energy objectives. These might include sustainability, embodied energy, and energy in use targets, supported/demonstrated by processes such as Passivhaus, Breeam, Leed, Energy Performance Certificates, etc. Benchmarking of metrics with similar facilities will be an important reference point. Energy in use in kWh/m², carbon per person, kg Co2/m², etc. will all become increasingly common metrics.
As designers and operators, we will primarily promote facilities which encourage and inspire people to engage in activity. The control of light, comfort and materiality will all have a bearing on user experience and the ability to meet sustainability criteria. These criteria are cojoined and should not be seen as separate.
IAKS is taking a number of steps through its expert circles, webinars and publications to share good practice in this area. This "sb" is showcasing examples where these factors have been taken into consideration in their designs.
təməsew txʷ / Sea Otter House in New Westminster, Canada is an all-electric building using carefully controlled natural light and features such as gravity fed filtration. It will be Canada Green Building Councils first Zero-Carbon building in design and on track to receive LEED Gold certification.
At MHP Arena in Stuttgart, Germany the decision was taken to refurbish and reuse an existing stadium. This can be a major factor in reducing whole-life embodied carbon as demonstrated in this project where hospitality and accessibility have all been considerably improved.
Östermalmshallen Padel in Mölnlycke, Sweden highlights how buildings can be designed for another life thus extending the use of structural materials in the context of circular economy.
Pimpama Sports Hub in the City of Gold Coast, Australia was designed to achieve 100% energy self-sufficiency. It sets a new benchmark for environmentally-conscious design while fulfilling vital community needs.
The new Sports and Arts Centre at Hongling High School in Shenzhen, China levels up the university campus’s social side of sustainability by creating a venue that provides broader spaces for cultural and sports activities, while rebuilding internal connections and communication within the campus.
Finally, the TFI Institute at RWTH University in Aachen, Germany offers insights from their “Bioturf” project, conducted into synthetic turf systems with the aim of giving preference to bio-based textiles, eliminating infill and making the production process itself more sustainable.
I hope that these examples of sustainability will inspire you to implement sustainable design and operation in your next sports and leisure projects.

HOW TO CREATE SPORTS FACILITIES THAT MEET THE NEEDS OF TODAY?
IAKS NORDIC BRANCH MEETING AND STUDY TRIP TO HELSINKI, FINLAND
18-19 SEPTEMBER 2024
Author: Jarkko Rantamäki

The City of Helsinki kindly offered its hospitality when IAKS Nordic gathered about 30 people from the public and private sector for a branch meeting in Finland. The idea was to welcome existing and potential new members from Scandinavia for a two-day exchange and a study trip to Helsinki.
As capital of Finland, Helsinki's Unit for The Promotion of Physical Activity has an organization of 480 people and an annual budget of approximately 72 million EUR. 800 different sports facilities are operated, together with many outdoor facilities and recreational activities. Minna Paajanen, Head of Unit, and Kimmo Isotalo, Senior Planning Officer from the City of Helsinki, Unit for The Promotion of Physical Activity explained its structure.
A growing proportion of Helsinki residents participate in some form of sports, with some studies reporting 80-90 % of the population engage in exercise at least occasionally. However, the disparities in physical activity levels are widening. Despite increased participation in exercise, the average Finn still spends two-thirds of the day sitting or lying down. Statistics show teenagers drop-out in organized sports, but self-organized activities stay mildly popular.
PROMOTING ACTIVITY
The City of Helsinki's vision for 2025 to 2030 is to get every different section within the city working towards a healthier and physically active lifestyle. Knowledge-based management as part of the strategic planning guarantees the most accessible and diverse network of sports and outdoor facilities in the future. The city’s mission is to advocate and facilitate exercise, outdoor activity, sports, and daily active living.
IAKS Nordic President André Flatner shared insights about IAKS as a non-profit association: Who we are, where we are located
and what we do. André presented the different expert circles IAKS offers regarding sports facilities. IAKS Nordic is committed to championing for sustainable and high-quality indoor and outdoor sports and leisure facilities that are fully inclusive, universally accessible, and socially relevant, focusing on public value, innovation and sustainability. This is also visible by the events provided: webinars, seminars, study trips, conferences, branch meetings. André ended his presentation with some interesting upcoming events that are happening next year 2025, for example, the Swedish Sports Summit in Gothenburg, and the IAKS Congress in Cologne.
INCLUSIVE DESIGN FOR LOCKER ROOMS & OUTDATED CONCEPTS
Daniel Glimvert, operation coordinator from The Swedish Research Council for Sport Science, presented an interesting report by Swedish architecture firm WHITE arkitekter. It shows that more and more people do not feel safe in the typically designed changing rooms. Most traditional locker rooms are rarely used, because they either exclude certain groups or are not accessible and therefore do not meet the demands of today’s needs. The report also presents design ideas for different types of situations, whether it is a sports hall, swimming hall or even an outdoor facility.
After a coffee break and intense discussions, Ola Mattsson from LOA fonden (The Danish Foundation of Culture and Sports Facilities) shared his thoughts on “Why hold on to outdated concepts?” The world has changed, there are a lot more different types of self-organized activities, and still we design and build most of our sports facilities for the organized sports. It is crucial for the success of project to get involved the end user right from the beginning. This leads to much more ownership towards the project and creates more value for its users.
LEAVE THE WORN- OUT WAYS
I n every country we see a decrease in public health, lack of physical activity, depression, obesity and yet we keep making same types of sports buildings with pre-determined layouts expecting for different results. Mike Lawless, LA Architects Director and guest speaker from the UK, encouraged participants to critically think the way we are building and to ask questions such as why are we designing this and why are we paying for that? However, the question “Who are you building for” is even more important. Most people are no athletes - so who are the target groups when building sports and leisure facilities? At the end, physical activity and sports should be something everyone can enjoy.
Both Ola and Mike had a clear message: Listen to the needs of the local users in the early stages of the projects and spend time asking the questions “why” and “how” before rushing into “what” we are actually going to build.
Jarkko Rantamäki closed the meeting, summarizing the knowledge and experience shared throughout the day. He thanked speakers and participants for their valuable contribution for making this event possible for the first time in Finland. André Flatner highlighted the importance of knowledge sharing and networking that IAKS Nordic can introduce for its current and future members. Webinars with focus issues, but also inperson meetings and seminars in other Nordic countries with interesting topics to discuss!
20 % GREEN SPACE IN JÄTKÄSAARI AREA
Jätkäsaari is a seaside district. The compact construction of sheltered and closed residential blocks, street-level shops, and trams make Jätkäsaari feel like an urban inner city. Construction of Jätkäsaari began in 2010 and will continue until the end of the 2020s. The Hietasaari area was the first to be completed, and construction is progressing in stages towards the southern shores.
One fifth of Jätkäsaari’s area, or about 20 hectares, will provide parks with room for exercise, relaxation, and play. When ready, the largest green area, the sports park Hyväntoivonpuisto (Park of Good Hope), will be a one-kilometer-long and nearly 100-metre-wide oasis containing the island’s main light transport routes. The park won the 2020 "Environmental Structure of the Year" award.
OODI - HELSINKI CENTRAL LIBRARY
O odi is a striking building with its glass and steel structures and wooden facade. The design by ALA Architects is a combination of traditional and contemporary flavours. The concept has been developed into an arching form that invites people to utilize the spaces and services underneath, inside and on top of it.
Apart from the top floor, Oodi’s facade is made entirely from wood (spruce), which softens the general appearance of the architecture around Töölö Bay. The energy-efficient library is an impressive and alluring calling card for Finnish architecture.
Töölönlahdenpuisto Park is a central park area within the Helsinki inner city, surrounded by its cultural facilities. Landscape architect Jere Saarikko from the City of Helsinki presented some new elements and interesting diverse activities. A functional playground and a barbecue spot, new park furnituresuch as swings, benches and sun-chairs - were installed in the north side of the park. New plants were added to improve comfort. The lawns of the park have been transformed into an impressive field of flowers. New playgrounds, game and hangout spots were added. Of course, the weather was excellent, so those attending enjoyed the final sunny days before the harsh autumn weather begins.

Experts from the pool and spa industry from all over the world met in September in the historic setting of the Vienna Hofburg. IAKS Austria co-organised the Pool Forum, which took place from 18 to 19 September in the historic rooms of the Vienna Hofburg. Distinguished speakers from all over the world, including Australia, Canada, Germany, Norway, Spain, Switzerland and the United Kingdom, took up the invitation of Harald Fux, President of IAKS Austria. They enriched the programme with exciting lectures on innovative ideas and sustainable solutions for the operation of modern pools.
SUSTAINABILITY, DIGITISATION AND ENERGY EFFICIENCY
The central theme of the conference was the sustainability and energy efficiency of swimming pool operations. In view of rising energy costs and the challenges of climate change, these factors are becoming increasingly important. Other areas of focus included the optimisation of operational processes and the promotion of sustainable practices, as well as digitisation as a key to improving efficiency and to implementing sustainable strategies.
NETWORK MEETING
The accompanying trade exhibition gave participants the opportunity to find out about the latest products and services of the pool industry. As respite from the demanding programme, the networking dinner on the evening of 18 September provided an excellent opportunity to socialise and exchange ideas in a relaxed atmosphere.
IAKS SWIMMING POOL EXPERTS
On 19 September, the IAKS Expert Group on Pools also met under the chairmanship of IAKS President Dr Stefan Kannewischer. The international experts engaged in a lively exchange on specific topics relating to the planning, technology and operation of pools. The focus was on innovative pool concepts, sustainability and the development of the digitised and energyefficient pools of the future.
The 2024 Swimming Pool Forum proved to be a successful and well-organised event that provided valuable inspiration for the future design and operation of swimming pools and, above all, strengthened international ties within the industry. The organisers forward to the next forum and to new, inspiring ideas for the swimming pools of the future.
EXCURSION TO VIENNA’S POOLS
O n 17 September, in the run-up to the conference, Harald Fux invited participants to an exclusive excursion to two of Vienna’s most important and most beautiful pools. The programme started with a guided tour of the venerable Amalienbad, which opened in 1926 as a public swimming pool and still impresses today with its Jugendstil and Art Déco features. After this trip to historic Vienna, the group visited the Therme Wien spa. Archi tect Ulle Tillmanns gave a tour of the ultra-modern complex and provided interesting insights into one of Austria’s most innovative wellness facilities. The tour of these two very different facilities not only provided interesting insights into architecture and management, but also showed the diversity and stature of Viennese bathing culture.

Renderings: POOL out of the BOX / 4a Architekten
The world’s first temporary indoor swimming pool with a modular wooden design is being built in Stuttgart. The contract for the forward-looking project has been awarded to POOL out of the BOX as the general contractor and to its planning partners.
Local authorities are often faced with major challenges when existing swimming pools are refurbished or new ones built. So that citizens can continue swimming, temporary solutions would be ideal. With this in mind, POOL out of the BOX GmbH, together with 4a Architekten and the Swiss timber construction company Blumer Lehmann, as well as other experienced partners in pool construction, has applied a modular construction approach to the design and functional and technical requirements of a pool. The modular wooden design and the pool’s almost complete prefabrication in the factory make it possible to erect it at different locations, dismantle it, relocate it and re-erect it – and all in a short time.
NO ONE MISSES OUT ON THE PLEASURE OF SWIMMING
In the award process, the building construction office of Land capital Stuttgart was impressed by the innovative design approach of the temporary, modular and dismantlable pool. In June 2024, the contract for the world’s first indoor swimming pool with a wooden modular design was awarded to POOL out of the BOX GmbH and its planning partners. The POOL out of the BOX approach enables Stuttgart’s municipal pools to provide their citizens with alternative swimming opportunities for the transition phase while existing pools are being refurbished or new ones built. The first modular pool will be erected in the Zuffenhausen district of Stuttgart in early 2026. Planning is already underway at further locations.
MODULAR CONSTRUCTION AS AN ARCHITECTURAL DESIGN FEATURE
The compact building has two floors: the pool entrance, plant and staff rooms are on the ground floor. The upper floor houses
the pool hall with the changing rooms and sanitary facilities. The pool hall accommodates a 25-metre stainless steel pool with five lanes and a partially movable floor. This makes it possible for use by several school classes at the same time. The interior finish, furnishings and equipment for the various modular rooms are also prefabricated in the factory and interconnected via interfaces on site.
The modular design is consciously used as an architectural design feature. This is reflected, firstly, in a clear structure resulting from the individual modules and, secondly, in the design of the façade, with different shades of grey in the wooden cladding lending outward expression to the modularity and giving the building an authentic appearance.
The wooden construction and the high degree of prefabrication of the room modules are an alternative to traditional construction methods, ensuring sustainability and efficiency. The POOL out of the BOX approach is thus on track to meet the goals of the Green Deal and the requirements of EU taxonomy, and is thus in line with the cradle-to-cradle principle.
CANADA’S FIRST ZERO CARBON AQUATIC CENTRE
TƏMƏSEW TXʷ AQUATIC AND COMMUNITY CENTRE IN NEW WESTMINSTER
Author: Paul Fast, Rebecca Holt
Photos: Nic Lehoux
təməsew txʷ / Sea Otter House Aquatic and Community Centre is woven into the landscape with a dramatic unifying roof. Designed by hcma architecture + design, təməsew txʷ has been designed for all ages and abilities, and for how communities engage in recreation today and into the future. The facility puts a greater focus on community connections and wellnessbased activities, alongside more traditional sporting and fitness pursuits.

Construction costs
The CAD 114 million, 10,684 m² combined aquatic and community centre is Canada’s first completed all-electric facility to achieve the Canada Green Building Council’s Zero Carbon Building-Design Standard, a significant transition for a building typology that has traditionally been one of the largest emitters of greenhouse gas emissions for many local governments. The pool facility is also the first to use a gravity-fed filtration system, which reduces the need for chlorine usage and creation of associated harmful byproducts, resulting in improved air and water quality.
RECLAIMING THE NATURAL LANDSCAPE: SITE CONSIDERATIONS
The təməsew txʷ Aquatic and Community Centre is situated on the edge of a residential neighborhood north of the Fraser River, which has been a cultural and economic life source for indigenous peoples for thousands of years. Located on the site of the former headwaters of Glenbrook Ravine, which was lost to development over the preceding decades, the project takes a strong stance toward reconciliation with the natural character of the landscape.
Prioritizing an east to west cardinal orientation over the colonial urban grid, the building sits along the natural topographic line
of the former ravine, counter to the residential streets that surround it. The headwaters to the north have been reconnected with the remaining branch of the ravine to the south, establishing a major public green space and rain garden directly adjacent to the South Plaza of the facility.
Additional significant physical constraints influenced the design approach: the Canada Games Pool and Centennial Community Centre, two 50+-year-old buildings that were on site and had to remain operational throughout construction before being replaced. A major regional sanitary line also runs through the site, which could not be built upon.
THE EXTERIOR: A
SINGULAR FORM
Running the length of a city block, the centre succeeds in both blending into the landscape and creating an iconic civic expression. The stepped, modulated elevation achieves a human scale where the building touches the ground, anchoring it into the re-established ravine space, while the strong black roof unifies the diverse program elements into a singular form.
The site opens out to the community on four sides and two major civic plazas act as entry points, connected by the free and expansive lobby, which draws visitors in. Located next to the gymnasia, the North Plaza encourages activity, recreation, and informal gathering. The adjacent facility walls can also be opened, allowing indoor programing to move outside. The South Plaza, situated next to the recreated ravine space, provides a sense of arrival with bridges across the rain garden and a densely vegetated landscape. A major public sculpture by Squamish Nation artist James Harry called Miyiwts (“Water’s Edge”) welcomes visitors and honors the Host Nations to whom these territories belong.
THE INTERIOR: COMMUNITY AND WELLNESS HUB
T he spacious double-height lobby acts as a vibrant community heart for the building. It features a significant, local heavy timber glulam roof, with a skylight illuminating the space and drawing people in. A sculptural steel spiral stair anchors the lobby and marks connections to the east and west wings of activity space. Large glass openings, flanked by acoustic wall paneling, connect the lobby to interior program spaces, allowing activities to spill into the lobby on both levels.
In the east wing, the design embraces a broader trend in wellness focused aquatic facilities, while also offering competition-level facilities. Under a folded plate mass timber and steel girder roof, the multi-use leisure pool is suitable for all generations and combines 25m lap lanes with spray elements and a lazy river that can be used for play and rehabilitation. Leisure swimmers can reach the outdoor sun patio that overlooks the ravine space through large glass bi-folding doors.
The eight-lane, 50m lap pool and two diving platforms are enclosed by a sawtooth roof structure formed by a hybrid steel
truss and mass timber (cross laminated timber) system. This roof form welcomes indirect natural daylight from the north, which is most conducive for athletic performance and reduces the need for artificial light. This gentler, indirect light also reduces the risk of glare for swimmers and lifeguards. The roof structure also houses the mechanical and electrical systems required for the east wing of the building.
Above the pools, the second level fitness centre nestles into the nooks and crannies between the large roof volumes, giving patrons different views onto the aquatics and outdoor spaces depending on their activity and location.
The interior design material palette reflects the timeless exterior expression where matte black standing seam metal roof elements enter as acoustic wall treatment and off-white wall tile is warmed by the wooden structural elements above. With water playing a significant role in the aquatic spaces, its glossy blue and reflected light was considered a primary material in the palette.
COMMUNITY ENGAGEMENT
E xtensive public and stakeholder group engagement occurred over two years and involved over 3,000 people, including urban indigenous, Host Nations and multicultural groups, and an accessibility committee. Community input steered many of the programmatic decisions that guided the design of the facility.
A naming advisory panel gifted the name təməsew txʷ to the centre. Meaning “sea otter house" in the Down River language of local First Nations, the panel chose it because of the playfulness, joyfulness, and family-oriented nature of the sea otter, which reflects key themes that emerged during community engagement. The indigenous knowledge holders involved have requested that the spelling of the center’s name not be anglicized.
INCLUSIVITY + “KEEP IT FRESH” INITIATIVE
Inclusive design and physical accessibility are core aspects of the facility’s planning and detailing, evidenced by the generosity of circulation space; high contrast signage that includes braille and tactile directories; fully universal washrooms with adult change tables and lift devices; ramps and zero-entry conditions into the leisure and family hot pools; as well as a transfer ledge in the adult hot pool and moveable floor in the 50m pool. The pool change rooms offer options for all-genders as well as dedicated male and female spaces. The project will receive its Rick Hansen Foundation Accessibility Gold Certification by the end of 2024.
Thinking beyond construction to operations, hcma has worked to City of New Westminster staff to develop the ”Keep It Fresh” initiative for the owner, which aims to educate swimmers about the connection between showering, water cleanliness, air quality, and energy performance. Lifeguards will be the primary ambassadors of this campaign, communicating to swimmers how the simple act of showering before entering the pools can have a significant impact on water and air quality.
STRATEGIES TO REDUCE ENERGY CONSUMPTION
AND GREENHOUSE GAS EMISSIONS
The building's compact massing and form factor were shaped by site conditions, with the existing facility remaining operational during construction and critical infrastructure running through the site. Although these constraints limited the optimization of the form, the design still significantly contributes to overall performance.
The building’s orientation and program overlay were optimized for energy efficiency, with primary glazing along the south facade and carefully angled overhangs and roof slopes for solar shading and photovoltaic panel efficiency. The envelope design addresses thermal bridging and emphasizes airtightness, while large overhangs provide shading on the south, east, and west facades. The stepping nature of the facade further enhances vertical shading along the south-west elevation.
Natural ventilation is a key feature, with substantial portions of the envelope designed to open, allowing fresh air into the main gymnasium and creating indoor/outdoor play spaces. The facility also maximizes daylight through large openings and clerestories, reducing the need for artificial lighting. Triple-glazed clerestories above the lap pool ensure abundant natural light, enhancing the space's ambiance.
Heat recovery ventilators capture waste heat from energy-intensive pool systems. The electric-based mechanical system, supported by heat pumps and back-up electric boilers, significantly reduces carbon emissions. The heat-pump system is supported by back-up electric boilers to support reheating pool water when it's drained and refilled a few times a year (a very energy intensive process).
The leisure pool and the 50m lap pool are separated by a glass wall to maintain different air and water temperatures, optimizing energy efficiency and user comfort. This design creates two distinct comfort zones: a warmer area for leisure activities and a cooler environment for high-performance swimming, addressing the discomfort of cold temperatures often noted in other aquatic facilities without this separation.
A first for Canada, the gravity-fed filtration and disinfection system reduces the need for chlorine usage and creation of associated harmful byproducts. The system is expected to have a significant impact on patron experience, as well as minimizing pump energy consumption by almost 50% and improving air and water quality.
As well as active users, the facility liberally caters for viewing areas, waiting zones, hang-out space, and spectators with generous provision of seating in the form of large concrete bench seats and timber seats.
ON THE ROAD TO SUCCESSFULLY MINIMIZE ENERGY USE
t əməsew txʷ Aquatic and Community Centre is Canada’s first completed all-electric facility to achieve the Canada Green Building Council’s Zero Carbon Building Design Standard, a significant transition for a building typology that has traditionally been one of the largest emitters of greenhouse gas emissions for many local governments. təməsew txʷ is also pursuing LEED v4 Gold Certification, influencing the sustainable design strategies employed for the project and maximizing co-benefits
between the two rating systems. It is aiming for a 92% reduction in greenhouse gas emissions compared to the existing facility, and completely eliminates building fossil fuel combustion.
To address the stringent requirements of the Zero Carbon Building Standard, hcma engaged directly with the Canada Green Building Council to share knowledge on the unique issues and energy needs of aquatic facilities. hcma collaborated to establish thresholds of performance that best reflect the energy demands of a natatorium, balanced with less energy intense spaces in the surrounding community centre.
CAMPUS ACTIVITY SPONGE
RENOVATION AND EXPANSION OF SPORTS AND ARTS CENTRE AT HONGLING HIGH SCHOOL
Author: O-office Architects

In order to meet the demands of the significant increase in the number of students, the school decided to build a new sports and art activity space with a total area of 22,000 m² on the site of the original 6,000 m² old gymnasium – a crucial opportunity for the school's rebirth. The design by O-Office Architects attempts to re-establish the connection between the campus and its natural environment by incorporating new natural structures and symbiotic spatial logic, creating new campus spaces and a sense of place. Therefore, the design goal was to utilize the central area of the existing campus to create a comprehensive venue that provides broader spaces for cultural and sports activities, while rebuilding internal connections, communication, and sharing within the campus.

The new sports and arts centre totalling 8,000 m² features two large comprehensive sports spaces of approximately 4,000 m² each. These spaces accommodate a variety of sports, including basketball, badminton, table tennis, gymnastics, and swimming. More importantly, the passage through the ground floor of the sports and arts centre connects various parts of the campus,
naturally fostering diverse interactions and exchanges during daily commutes and various sports activities.
The "inclined" roof of the building hosts art classrooms (for instruments, vocals, and dance) and eight outdoor sports courts, interweaving between the dormitory and teaching areas.
BUILDING WITH NATURE
The new construction no longer adheres to the previous urban expansion model. Instead, the design focus shifted from mere quantitative expansion to addressing intrinsic issues within the building and site environment, leading to considerations of the architectural and campus spirit, spatial adaptability and flexibility, and comprehensive cultural aspects.
The design originates directly from the site and nature. The terraced buildings, from a topographical perspective, extend the
natural mountain form to the south, descending northwards at a slope of approximately 10%. Between the three terraced buildings there are two longitudinally undulating landscape spaces about 30 m wide, integrating various large-scale activity spaces. Above the continuous landscape space, modular truss boxes measuring 30 metres square are set up between the terraced buildings, housing rooftop outdoor sports courts, club activities, and indoor art classrooms. These activity modules, eight in total, follow the slope from south to north, forming a natural terraced rooftop activity cluster.

INTERWEAVING OF SPACE
Another key objective was to comprehensively reorganize the space and traffic flow of the Hongling campus through this construction update. Buildings should not only serve functional uses and provide spatial enclosures but also act as conduits and diffusers of campus traffic and generators of diverse activities. In other words, buildings should primarily function as platforms and networks, resembling a porous sponge where people can freely permeate, flow, and integrate.
The "superstructure" built upon the terraced infrastructure not only serves as a semi-outdoor natural activity cluster but also creates a rooftop landscape circulation network. On the east
side, it connects to each floor of the original teaching buildings via newly constructed corridors. On the north side, it links to the reshaped existing landscape and traffic terraces beneath the terraced buildings. The new comprehensive facilities at the east and north ends interweave with the existing campus, reprocessing and reweaving the previously unevenly distributed internal traffic into an organic whole.
The traffic space of all functional areas is provided to people passing through the sports and arts centre at the same time. Located in the centre of a high-density campus, the facility forms a threedimensional cross-traffic system that is connected in all directions and becomes the transportation hub of the entire campus.

STATICS VS DYNAMICS
T he definition and concept of education have undergone significant changes over the past decade, and this transformation is expected to continue and accelerate in the foreseeable future. Therefore, the flexibility and adaptability of campus spaces were essential for increasing the utilization frequency of school facilities, ensuring the most efficient use of limited campus resources, and accommodating the unpredictable demands of future campus activities.
The infrastructure strategy of this project is to enable all large indoor activity spaces to occur continuously within the terraced buildings. The undulating terrain shapes indoor activity areas suitable for various types, with all areas being open and versatile. They can be relatively freely connected or separated to accommodate a wide range of envisioned, and even unforeseen, activities. Additionally, the rooftop steel truss box unit system provides space for future adjustments to accommodate changes.
REDUCED CARBON EMISSIONS
T he mountain-shaped buildings on the east and west sides block the strong direct sunlight. The two sports spaces of about 4,000 m² and the activity unit boxes on the upper part of the mountain-shaped buildings fall down from south to north along the mountain, effectively organizing the natural ventilation introduced from the southern mountain. In the hot and humid climate of the Pearl River Delta, all internal sports spaces use natural ventilation without air conditioning systems, which greatly reduces the energy consumption in use.
The very restrained use of materials effectively reduces the carbon emissions of the entire building. In addition to the main structure materials – the lower reinforced concrete structure and the upper steel structure – the building only uses gabion walls filled with lightweight volcanic stones on the exterior wall and aluminium alloy glass doors and windows for a small part of the opening. Without any additional decoration, the appearance and interior space effects of the building are truly reflected by the functional form and combination of the building itself.

SOCIAL HUB AND SPORTING CENTRE
The Gold Coast, particularly its rapidly growing Northern region, faced a shortage of sports and community facilities. Pimpama Sports Hub was developed to address this gap, offering a much-needed space for healthy living, social connection, and recreation. The hub serves as a social hub, sporting centre, and even an off-grid post disaster recovery centre.
WELCOMING SPACE FOR EVERYONE
The precinct needed to accommodate a diverse range of daily activities, catering to a variety of community needs. With key features such as a five-pool aquatic centre, a health and fitness centre, tennis and netball courts, playgrounds, a pedestrian and cycleway, and more, the hub is designed to be a welcoming space for everyone – from sports enthusiasts to families seeking a day out. The facility is managed by the council with key areas allowing varied hours of operation, and the café operated by a social enterprise playing a pivotal role in supporting disadvantaged youth by providing employment opportunities.
DESIGN ENCOURAGING INTERACTION
Pimpama Sports Hub is a model of well-integrated functional and adaptable areas that can respond to changing user demands building design resilience. The aquatic centre houses competition-grade pools, while fitness and social spaces like the community centre and café complement the sports facilities. The design encourages interaction between spaces, allowing easy navigation and continues to foster community involvement and inclusivity.
COLOUR SCHEME
REFLECTING NATIVE VEGETATION
Tones and colours have been curated to reflect new growth and natural cycles such as regeneration of native vegetation after bush fires. These themes also reflect the aspirations of a developing community committed to healthy lifestyles.
The facility’s colour scheme drew inspiration of landscape tones from the site’s natural environment. Pinks, greens and browns found in leaves and tree trunks were matched and applied to materials to ensure the harmonious integration of the built form.
COMMITMENT TO SUSTAINABILITY, MATERIALS, AND ENERGY CONCEPT
T he development process prioritised a triple bottom line approach, focusing on environmental, social, and economic factors. Aquatic centres are known for their high energy consumption, especially in winter when water and space heating requirements are increased. Pimpama Sports Hub is designed to achieve energy self-sufficiency on an annualised basis.
The primary initiatives used to achieve this include nearly 2,000 solar panels, over 300 kW of battery storage, and a co-generation plant capturing waste heat to warm the pools. Its sustainability measures equate to a 5-star Green Star rating, and projections indicate the centre will operate at zero cost to the council within 2-3 years of opening.
Further to the sustainable technologies implemented, passive design strategies were prioritised such as large roof overhangs, facade screening, and mixed-mode ventilation. These strategies ensured optimal thermal comfort and energy efficiency was achieved throughout the facility.
Material selections were driven by sustainability goals. Materials with high-insulation values were selected, and the use of natural ventilation and solar screening helped reduce energy demands.
Additional features include 250,000-liter rainwater tanks for pool replenishment, toilet flushing, and irrigation, ample bike spaces and end-of-trip facilities, and six electric vehicle charging bays. Storm-water filtration is managed through naturally filtering bio-basins, while retaining existing vegetation serves to enhance cooling, enrich visitor experience, and boost ecological value.
ACCESSIBILITY CONSIDERATIONS
Throughout the project, collaboration with external stakeholders such as City of Gold Coast focus groups, the local community, allied health organizations, Tennis Australia, and Netball Australia, ensured a holistic approach to development, fostering community involvement and inclusivity.
Accessibility was a core consideration, with the facility going beyond statutory access requirements, ensuring all spaces are equitable for people with a disability. This inclusive approach extends to every part of the design, from the 1.1 km pedestrian and cycleway to the fully accessible health and fitness spaces.
CHALLENGES
FACED DURING
THE DESIGN AND CONSTRUCTION PROCESS
O ne of the most significant challenges was balancing energy requirements with limited roof space for solar panels. By incorporating the co-generation plant, the design team overcame this issue, ensuring that the facility could be energy selfsufficient without the need for additional infrastructure.
Another challenge was meeting the ambitious sustainability goals while ensuring the project remained economically viable. By prioritising robust, long-lasting materials and integrating innovative energy solutions, the project team was able to create a facility that not only met but exceeded expectations.
Furthermore, the design team worked with the site’s existing steep slopes and natural watercourse to form unique features such as a terraced seating area on a hillside. Shaded green spaces encourage nature-based play and community gatherings.
CONCLUSION
Pimpama Sports Hub is a model of modern, sustainable design, setting new standards for how community spaces can serve both people and the planet. Through its innovative energy solutions, commitment to accessibility, and community-focused layout, the hub is more than a sports facility – it’s a vision for a greener, more inclusive future.

On the occasion of the UEFA EURO 2024, the MHP Arena has now been modernised for the sixth time, as previously by asp Architekten. The home ground of VfB Stuttgart football club is thus a prime example of the further development of the existing structure as the top priority of sustainable construction. And it shows that one of the longest-serving stadiums in Germany can also be one of the most advanced.

WHAT’S NEW? AN OVERVIEW
A s a football stadium and event location, the MHP Arena is a building designed to offer visitors an exclusive experience. That is why it has been the stated aim from the outset to pay equal attention to all three pillars of sustainability. Important roles are played by economic and social sustainability in addition to the ecological principles of sustainable construction. Elementary aspects of circular construction have been implemented by making use of the existing structure and preserving the shell as far as possible, reusing and selling components and materials, and processing and re-installing the demolished concrete.
Probably the biggest task has been undertaken right at the heart of the stadium – and while it was still in operation. The main stand, parts of which are now 50 years old, has been refurbished and extended to the membrane roof supports, thus allowing an increase in the number of business seats from 1,628 to 2,545. The lounge areas have been increased from 2,150 m² to 3,710 m², and the bar and food serving areas have been almost doubled from 336 m²
to 632 m². The capacity of the MHP Arena means that VfB Stuttgart plays in the third largest stadium in the Bundesliga – after Borussia Dortmund’s Signal-Iduna-Park and FC Bayern Munich’s Allianz Arena.
Furthermore, the player and press areas have undergone redesign in line with UEFA requirements for EURO 2024, thus more than doubling these areas in size as well. The new facilities include team dressing rooms, functional rooms, a media centre, a VIP area and a production kitchen.
In addition, the integration of a conference centre has increased the stadium’s usage intensity many times over. The MHP Arena now opens no longer just 17 times a year for football matches, but daily for other events such as conferences. Both factors contribute to environmental and economic sustainability. As for social sustainability, the new large kitchen, for example, enables all meals to be freshly prepared on site using regional ingredients.
HIGHEST STANDARDS OF FUNCTIONALISM AND EXCLUSIVITY
In addition to the player and press areas, the aim has been, of course, to raise the fan experience to a new level. The new Tunnel Club, as an exclusive business area, offers fans a unique insight into the match day action. Up close, they can watch the players emerge from the team dressing rooms and run onto the pitch or give interviews after the game. The range of exclusive experiences has also been greatly increased, with a further 917 business seats being created, for example, as a result of the refurbishment work.
The new main stand also serves as a conference and events centre, making the MHP Arena an exciting destination even when football or other sports events are not taking place. The centre, which includes a piano bar and lounge, offers a completely new visitor experience – for conferences, conventions or trade fairs, for example. The interiors, with individual units ranging from 200 m² and 750 m², are designed so that up to eight conferences can take place at the same time.
Spacious staircases have been created for visitors to the existing second tier. The circulation area on level 3 has been significantly enlarged and the food and beverage offering has been significantly improved. Regional products are prepared in the newly installed large kitchen.
IN THE SPIRIT OF SUSTAINABILITY –IMPLEMENTATION
AND OPERATION
Sustainability has been the guiding principle behind the entire rebuilding project. Probably the greatest contribution in this regard has been the consistent reuse of existing structures and infrastructure, as well as the greatest possible retention of the grey energy already incorporated. The aim has been to keep as much material as possible in the cycle and to reuse and recycle it. Of the main stand, for instance, almost 100 per cent of the demolished concrete has been reused within the stadium. In this regard, in cooperation with the structural engineers schlaich bergermann partner, the planning and tendering for the shell construction already specified carbon-reduced recycled concrete.
Thanks to collaboration with a local demolition company and the concrete supplier, it has been possible to put the concrete from the demolished grandstand to environmentally sensible
use within the stadium. The demolished material was recycled into resource-conserving concrete at Stuttgart’s harbour, just a few kilometres from the stadium. This is relevant for a construction project with such high demands on the concrete, as it is not standardised and special permission was required for its use. What makes this concrete special is that it is CEM III, whose carbon savings result from the use of low-clinker cement as an aggregate.
Other components and materials that could no longer be reused on site were catalogued by a start-up company, resold via its platform and thus kept in the cycle.
However, the MHP Arena’s sustainability does not end with the construction work. In the future, the aim is to close cycles during operation as well. For example, waste heat from refrigeration units is now being recovered. And, last but not least, the floodlights have been converted to LED.

FROM SHELLFISH TO PADEL
REPURPOSE OF TEMPORARY MARKET HALL TO ÖSTERMALMSHALLEN PADEL
Author: Tengbom

In one of the biggest upcycling projects in Sweden, the temporary market hall from Stockholm (Östermalmshallen) was given a new lease on life. The building was disassembled and shipped to Mölnlycke, and rebuilt as a padel hall. Since then, padel courts have replaced the fish and shellfish counters, but the exclusive feel remains intact. The wood-panelled walls with a visible structure create that sense of exclusivity, for a result that is far from the standard tin boxes that house many padel halls around Sweden. The locker room floors and walls are lined with big, beautiful terrazzo tiles, while the restaurant and bar offer views of both the lake and the padel courts.

Over the course of a four-year renovation of the 1888-built Östermalm Market Hall, the market traders were moved to a temporary hall out on the square. The largely pre-fabricated building, designed by Tengbom to be easily assembled and disassembled, was constructed with a frame made of glulam columns and veneer beams, as a lightweight construction was necessary due to the underground station below the square. Passers-by and visitors alike could still cross the levels of the square on the market hall’s sloping floors.
Like the older market hall, the temporary hall is notable for its visible construction of slim columns and beams, spacious-
ness, and good distribution of natural daylight. The building’s columns were designed with a cross-shaped section to be placed at the intersection of criss-crossing beams, with some of the ceiling modules split diagonally by triangular skylight lanterns. The facade was delivered in modules, with a frame of studs, partly covered with birch plywood on the interior and exterior, with large glass windows for views both inside and outside. The lower facade was covered with untreated pine battens of varying depth to cover the module seams. The upper facade is covered with multiwall polycarbonate sheeting to let in diffuse daylight and shine like a lantern at night.

“NO
ONE WANTS TO TEAR DOWN AN ATTRACTIVE BUILDING”
After the original Östermalm Market Hall reopened in March 2020, the City of Stockholm decided to sell the temporary hall to the property company Wallenstam, which found a new function for the building and a plot that could fit its dimensions. Wallenstam saw the potential of reusing materials and retaining the building’s fine architectural characteristics. The temporary hall was disassembled and moved by environmentally certified trucks to Gothenburg in spring 2021, then to Möln lycke, where the inauguration of Östermalmshallen Padel was held in April 2022.
ADAPTED FOR PERMANENT USE
T he building was reconstructed on a concrete basement slab, with a support wall at the lower end of the hall. The new hall reused wall and ceiling frames, multiwall polycarbonate sheetings, exterior glass windows and one of two corten steelcovered entries. The module-based roof system of beams and visible steel elements is designed with millimetre precision, facilitating assembly and producing a satisfying result after reassembly. As previously, the facade is covered with pine battens, creating a relief effect that uses shadows to soften the large facade area. Unlike the temporary hall, the padel hall has been adapted for permanent use, with thermal insulation and an iron vitriol treatment to the facade.
INTERIOR PILLARS AND FACADE WERE EXTENDED
Inside, the wood has only been treated with a clear, fire-resistant varnish. The interior walls are covered with plywood and the sub-ceiling with wood wool tiles. The hall’s new purpose called for a higher ceiling and a few columns had to be moved to accommodate six padel courts. The columns were extended with specially made “steel socks”, in the same cross-shape as the columns, and steel transfer beams span between the columns and their original location at the cross-shaped intersection of the beams. The varying heights of these “socks” create an echo of the temporary hall’s sloping floor floating in the padel hall.
Padel courts cover the entire width of the hall, and the space is filled with the diffuse light that comes in through the multi-
wall polycarbonate sheeting. Instead of the two plywood clad mezzanine volumes that were located along the sides of the temporary hall, the building now has one mezzanine along the short side over the entrance and restaurant, with staff areas, multi-purpose rooms and a corridor with large rectangular openings facing the padel courts. Visitors can watch the activities inside the hall from the restaurant and corridor. At the same time, the padel players can see through the glass windows of the restaurant over the carefully designed outdoor seating space.
Wallenstam’s surprising choice for the temporary market hall’s new purpose and location allowed Tengbom to add additional dimensions to the architectural design, offering visitors an enriched experience. This padel hall truly stands out – and the fact that Wallenstam even reused the market hall’s name is a distinctive statement!

MAKING SYNTHETIC TURF MORE SUSTAINABLE
RESEARCH GROUP DRAWS ITS CONCLUSIONS FOR BIOTURF
Authors: Dr Claudia Post, Dirk Hanuschik, Dr Ulrich Berghaus

In Aachen, research is currently being conducted into synthetic turf systems with the aim of using bio-based textiles, eliminating infill and making the production process itself more sustainable. The authors Dr Claudia Post, Dirk Hanuschik and Dr Ulrich Berghaus explain the factors paving the way forward and outline how they expect the situation to develop.
Any amateur who enjoys playing football (or hockey) is aware of the benefits of synthetic turf pitches. Football clubs in particular with their many different children's, youth and adult teams benefit from the durability and intensive playability of the more than 5,000 synthetic turf pitches in Germany. Natural grass can only withstand around 800 hours of play per year, as compared to 2,000 hours for synthetic turf. This fact alone has persuaded many clubs to replace their unpopular cinder pitches with synthetic turf over the last 20 years.
However, many of the systems currently in use have plastic infill. The purpose of this is to protect the pile yarns, also made of
plastic, from being torn out by studded boots. However, the EU-wide ban on the marketing of microplastics from 2031 means that clubs and local authorities have to be offered a viable alternative so that matches at clubs and schools can continue to take place.
This is where BioTurf comes into play. BioTexFuture (BTF) is an innovation space for bio-based textile research funded by the German Federal Ministry of Education and Research (BMBF) (https://biotexfuture.info) and is being led by adidas AG and RWTH Aachen University. The goal of the BioTurf project is to make synthetic turf systems more sustainable.
THE CHALLENGING STATUS QUO
To understand why currently used synthetic turf pitches are not sustainable enough, the following diagram shows the raw materials currently used and their processing through to the production, utilisation and thermal recovery of a synthetic turf compared to BioTurf's forward-looking approach.
Current synthetic turf systems are based on a mix of materials (pile yarn, infill, backing, latex and laminate). At the end of their useful life, most of the materials in this mix cannot be separated into their component parts and are not therefore recyclable.
Unfortunately, there are currently still not sufficient viable recycling options for synthetic turf removed when pitches are upgraded. If you look at the carbon footprint of a current synthetic
turf as its impact on the environment, the production of the plastic portion of a synthetic turf system causes carbon emissions of about 16.7 kg/m² and another 20.5 kg/m² after removal due to the lack of recycling options.
Another negative aspect is the infill, because to safeguard the playing properties of the synthetic turf, about 5 to 7 kg of additional plastic granulate per square metre is currently distributed across the pitch. Due to rain, wind and weather, this can enter the environment where it does not degrade. The released quantity of plastic granulate has to be regularly replenished to maintain the pitch’s playing properties. In the EU alone, the estimated 25,000 synthetic turf pitches release 12,750 tonnes of microplastic into the environment every year.

Pileyarnyarn
SHIFT FROM PETROLEUM - BASED TO BIO - BASED TEXTILES
70-80% of a product's environmental impact is due to resource consumption. With this in mind, the project partners have turned to bio-based raw materials.
• TFI - Institut für Boden- und Raumsysteme an der RWTH Aachen
• ITA - Institute of Textile Technology at RWTH Aachen University
• Morton Extrusionstechnik (MET, industrial partner and expert in plastic fibres)
As the point of departure for the development of BioTurf, the aim was to reduce the mix of materials in favour of polymer recyclability, to eliminate infill and to make the production process more sustainable. All the innovation projects under the BioTexFuture umbrella share the vision of transforming the textile value chain from petroleum-based to bio-based textiles and communicating this approach to the public.
To this end, the filaments/yarns needed for the new BioTurf synthetic turf should come from agricultural waste and be amenable to processing on conventional industrial equipment. In addition, the pile yarn should be firmly integrated into the backing in order to match the robustness and playability of its petroleum-based equivalent.
NEW THERMO -BONDING PROCESS
A s the industrial partner, Morton Extrusionstechnik (MET) successfully negotiated the industrial transformation of its extruders and filament systems without any major issues. On BioTurf, the new thermo-bonding process replaces the traditional latex back coating, which is highly energy-intensive due to the drying process and severely limits the recycling of the previous synthetic turf systems or even makes it impossible. On BioTurf, this technology makes the synthetic turf fully recyclable at the end of its useful life. During the development phase, thermo-bonding presented the team with the challenge that both the woven backing and the pile yarns are made of bio-polyethylene and thus have the same melting point, causing the backing to melt at the contact points with the calender roller.
CHARACTERISTICS OF THE THREADS AND YARNS
T he solution was to add a small percentage of bio-polypropylene to the weft and warp of the backing fabric. While not affecting the recyclability of the BioTurf synthetic turf, this slightly raises the backing's melting point. To stabilise the synthetic turf system, MET produced additional a film from recycled EOL (end of life) agglomerate – in other words, from old, removed synthetic turf pitches.
To replace the infill, an additional textile component had to be developed in the form of textured yarns to provide mechanical support for the pile yarns and to create an elastic layer. The second yarn is slimmer than the synthetic grass yarns, but it is highly crimped and elastic, and can thus keep the grass filaments upright and facilitate the usual ball roll behaviour.
In a pilot project, the new BioTurf was installed at the RWTH Aachen University Sports Centre. The feedback from the players has been thoroughly positive. The synthetic turf surface provides a firm footing even in the rain and allows a fast-paced game.
OUTLOOK
I n terms of sustainability, the use of bio-based and recycled materials, together with the new, innovative production processes, helps to significantly reduce the synthetic turf's carbon footprint. Based on MET's forecast output of 30 million m² of synthetic turf in 2025, the new BioTurf could achieve savings of 38,685 tonnes of carbon.
In addition to the high energy savings, however, the life cycle assessment also has to take account of the bio-based material used to produce the polymer, since there are major differences between crops in terms of cultivation, water consumption and the potential for nutrient overload in the soil. We can take comfort, however, from the fact that the synthetic turf of the future can be more sustainable. The technologies for this are already available. The raw materials can be reused with only small amounts added, so nothing stands in the way of transformation.

Swimming pools are often social meeting places and contribute to quality of life in a community. The design should take into account both ecological, economic and sociocultural aspects as well as aspects such as accessibility, security and the creation of communal spaces. However, the structural physical requirements for the building materials used must also be taken into account in the planning. Two impressive projects show how architecture, energy efficiency, sustainability and social interaction can be combined in swimming pools.
BLÜTENBAD IS CERTIFIED FOR SUSTAINABLE DESIGN
W ith the Blütenbad, the Düsseldorf-based architectural firm POS4 Architekten in North Rhine-Westphalian Leichlingen (Rhineland) has built a modern new building on behalf of Leichlinger Bäderbetriebs und Beteiligungs GmbH. With a total area of 2,726 square metres, the new indoor swimming pool meets the highest sustainability criteria, such as ecological, economic and sociocultural quality. As a result, it was certified as a “sustainable swimming pool” according to the Deutsche Gesellschaft für das Badewesen GmbH (DGfdB) and received the first certification for an indoor swimming pool in accordance with the BIM Level 2 (open BIM) guidelines as one of the first BIM plans in swimming pool construction. The operation of modern ventilation systems with heat recovery and special pump systems, which are installed in combination with a full-surface photovoltaic system on the green roof, not only increases comfort, but also minimises operating costs.
BRIGHT AND FRIENDLY SWIMMING AND WELLNESS AREAS
Inside, the bathing facilities feature a 25-metre swimming pool with sports swimming track, non-swimmer pool with adjustable floor, massage nozzles and splash shower, as well as a children’s bathing area with slide. There is also a spa area with a variety of saunas and steam rooms, including a Kneipp water treading pool, as well as a shop.
Large window fronts, light-coloured floors and colourful accents give the interior a bright and friendly character. The overall design is rounded off by bright Troldtekt acoustic panels, which are also suitable for the most humid and warm spaces, such as swimming pools, shower rooms and wellness facilities. They are mounted on the high ceiling above the white steel structure and provide a pleasant acoustic environment.
HALLENBAD FALKENSEE IS MORE THAN JUST A SWIMMING POOL
The citizens of Falkensee - a city in the eastern part of the Havelland district on the border to Berlin - have long wanted a place for sport, fun and coming together where tradition and modernity combine for a vibrant community. In 2020, more than 10,000 people voted in favour of the city’s largest construction project to date as part of a citizens’ decision. The new building was planned under sustainable aspects by BAUCONCEPT® Planungsgesellschaft mbH from Lichtenstein/Saxony, which with over 100 employees covers a diverse range of services throughout Germany. The sustainability aspects include a curtain facade that enables residue-free and sort-free dismantling, the use of renewable energy in the form of a PV system in combination with a green roof, the use of a rainwater cistern for water storage for irrigation of the green area, the type 1 sludge water treatment plant, light control via occupancy detectors and light sensors, and heat recovery via central ventilation units. The Falkensee indoor swimming pool with sauna, restaurant and bowling alley has now been completed and delights all generations with its diverse range and unique ambience.
STRIKING NEW BUILDING PROMISES SWIMMING ENJOYMENT FOR EVERYBODY
The new building with flat green roof and photovoltaic system stands out from the outside with its copper-coloured facade cladding and striking lettering. Ample use of glass also gives the building an open and inviting feel and allows visitors to enjoy exceptional views while swimming.
The accessible swimming pool with six 25-metre tracks, starting blocks, diving facilities and diving tower offers water depths of 1.80 to 3.50 metres. For beginners, there is a learning pool and a paddling pool with water games for the little guests. The 38-metre-long tunnel slide with timer, which is eye-catching with its bold blue colour, offers guaranteed fun.
ACOUSTIC ELEMENTS ADD COLOURFUL ACCENTS
Many colourful accents are used throughout the swimming area to give the swimming pool a very special touch. This is achieved in particular by a strip of multi-coloured Troldtekt® Line Design acoustic panels with a CNC-milled surface running along the walls. The rhombus-shaped Troldtekt floating acoustic clouds hanging above the paddling pool add further colourful accents. In the state-of-the-art bowling area, with four 23.50-metre-long wooden bowling alleys, black acoustic ceiling panels from the Troldtekt® Line Design series, combined with black and white plant motifs on the walls, lend the rooms a high-quality, elegant charm.
TROLDTEKT® ACOUSTIC PANELS IN DEMANDING ENVIRONMENTS
There are various requirements for the building materials when planning and implementing indoor swimming pools. As with other construction projects, they must harmonize with architectural expression, but at the same time meet several structural requirements. Troldtekt® acoustic solutions have very good sound-absorbing properties, can absorb and emit moisture and are therefore ideal for use as acoustic ceiling and wall cladding in wet rooms such as swimming pools. They are also allergyfriendly, robust and durable. The panels are manufactured in Denmark from wood and cement from Danish raw materials under state-of-the-art conditions. Troldtekt is both FSC® (FSC C115450) and PEFC-certified. The acoustic panels are Cradle to Cradle Certified® in the Gold category.
A GROUND - BREAKING MOMENT IN THE HISTORY OF FIELD HOCKEY

Polytan installs Poligras Paris GT zero, a climate-neutral synthetic turf that requires little to no watering. In March of this year, Africa’s first dry hockey pitch was inaugurated: a groundbreaking moment for hockey as a sport. The installation at St. Andrew’s School in Bloemfontein, South Africa, is an exemplary project for the entire continent, on which water is an extremely scarce and valuable resource.
At St. Andrew’s, the sports surface specialist Polytan installed a highly functional dry hockey pitch that does not require any sand in-fill or watering. The sustainable system is officially certified by the FIH. The world’s first certified “FIH Innovation Category Dry Turf Hockey Field” is a milestone in sustainable hockey, as previously, large amounts of water were needed to play professional hockey. Now, hockey can grow in popularity in the arid regions of the world.
ST. ANDREW’S IS THE PIONEER OF AFRICAN HOCKEY
South Africa’s love of sport was clear to see during the FIFA Football World Cup in 2010. Football and rugby are extremely popular there. Hockey is also increasing in popularity; however, the biggest challenge is water scarcity and sand-filled hockey pitches are widespread. In dry weather, they can barely be used at all. That’s why the prestigious St. Andrew’s School opted for Poligras Paris GT zero hockey turf from Polytan, which can be used even when dry and achieves Olympic quality with minimal watering. The sustainable synthetic turf system was installed by Trompie Sport, one of Africa’s leading sports construction companies. The new pitch will serve 33 junior teams and 10 senior teams at St. Andrew’s, who are among the best teams in South Africa.
POLIGRAS PARIS GT ZERO – CLIMATENEUTRAL AND RESOURCE-EFFICIENT
With Poligras Paris GT zero, Polytan has developed the world’s first carbon-neutral synthetic turf for hockey. The sports flooring manufacturer is advancing the development of sustainable systems without compromising on playing quality. The filaments of Poligras Paris GT zero consist of up to 80% bio-based fibre raw materials. Combined with the recyclable polyurethane wear coat, they result in a positive carbon footprint and ideal playing properties. The high-performance hockey turf enables a precise and dynamic game while ensuring maximum player safety, even during complex playing manoeuvres. The robust hockey turf withstands changing weather conditions, such as high UV radiation, and retains its attractive appearance for many years, even with intensive use. Polytan’s Turf Glide Technology minimises surface friction, which ensures unbeatably fast ball-rolling behaviour, increased player safety and significantly reduced water consumption.
DRY HOCKEY AS THE BASIS FOR THE SUSTAINABLE FUTURE OF HOCKEY
The opening ceremony of the dry hockey pitch at St. Andrew’s took place on 20th March 2024 and was attended by Deon Morgan, Member of the FIH Executive Board and President of the South Africa Hockey Association. He was visibly impressed by the project and remarked on its significance for the future of hockey: “Dry hockey is a great opportunity for the growth of our sport and I am confident that many more of these pitches will be built in South Africa and on our continent.” He thanked everyone involved, especially the global FIH supplier Polytan, and expressed his wish that the hockey players at St. Andrew’s might “train their abilities under optimal conditions and enjoy many exciting moments of hockey and friendship.”
Polytan has been committed to sustainability in sport for many years and develops sports surfaces and synthetic turf systems that enable peak performance, while being environmentally friendly. Ashley Appleby, International Sales Manager at Polytan, is delighted by the progress made in the development of sustainable hockey turf: “Our climate-neutral synthetic turf, Polytan Poligras Paris GT zero, was developed with Paris 2024 in mind. With the FIH certification, it can now be used for any dry hockey pitch – from school and club sports to international competitions like the World Cup.” Polytan has already equipped more than 25 pitches in 11 countries with Poligras Paris GT zero hockey turf. The system has proven itself in training and competition, is robust and extremely resource-efficient – a great advantage, especially in areas where water is a scarce resource. Regarding the pitch in St. Andrew’s, Ashley Appleby adds: “We are proud to have realised Africa’s first dry hockey pitch. It will enrich the entire hockey community and takes the sport one step closer to a sustainable success story.”
In January 2024, the first FIH Hockey5s World Cup took place in Oman, also on a dry hockey pitch from Polytan: further proof of the potential of dry hockey to conquer the world.

HET PRODUCES AND LIVES SUSTAINABILITY
As a manufacturer of products, responsibility towards the environment and its preservation for future generations is one of the central themes and concerns of our actions at HET. Since the company was founded over 30 years ago, we have been actively contributing to sustainability and environmental protection. With our ELTECPUR® product range, which is largely made from recycled rubber granulate, we make a significant contribution to conserving resources and creating something new from old materials in the recycling process.
In particular, old rubber tyres are used as a raw material for the manufacture of our products, from which we produce new and technically sophisticated materials for a wide range of requirements and applications.
In addition to the resource-saving and sustainable use of raw materials, our products are also characterised by the fact that they can be granulated again at the end of their life and reused as raw materials. The cycle is complete!
In this way, we help to create something new from discarded materials. Our ELTECPUR® products are used as fall protection surfacing and offer protection against injuries on playgrounds. As elastic tiles in sports and fitness areas, they offer protection against damage and help to reduce noise and vibrations.

LAWN COOLING IS BECOMING INEVITABLE!
rasenplan GmbH is the only company in Europe that builds energy-saving and CO2-free turf heating and cooling systems! For natural and artificial turf surfaces.
As a full-service provider, rasenplan has been building new turf heating and cooling systems, including CO2-free energy supply and the associated sports pitch work, since 2016. However, we also convert any existing turf heating system. All large supply and return pipes can remain in the ground. Only the heating pipes are newly laid. This results in very low construction costs.
Due to global warming, stadium turf is coming under increasing pressure. Complete failures due to fungal infestation are becoming more frequent. Due to the increasing heat, regeneration is no longer taking place. The hot summers are putting more and more pressure on natural turf. With the turf base layer - cooling by means of groundwater, you have perfect regeneration and no more growth stress in the natural turf! Groundwater pump system or air heat pump system, heating centre and turf heating control - rasenplan coordinates the entire project with competence and expertise from a single source. From the analysis to the feasibility study, planning, installation, commissioning and the required airter® system maintenance machine, the customer has a single point of contact.
