SHAPING THE FUTURE WITH CERAMIC BUILDING MATERIALS

Safety has always been one of the basic human needs. Architects play a significant role in meeting this need, because they have the ability to create robust and healthy living spaces. Throughout the company’s 200-year history, Wienerberger has striven to support architects in this role by providing them with the most innovative and sustainable solutions possible, and by taking a socially responsible approach to environmental and social considerations. Wienerberger applies the principle of ‘Improving people’s quality of life’ in all of it’s sustainability measures: from the considerate extraction of raw materials, to switching to energy-efficient processes, developing sustainable and innovative products, and taking a holistic approach to building design. All this is particularly relevant to us, because sustainable solutions facilitate the construction of durable and energy-efficient buildings, thereby delivering significant added value for our clients and making a positive contribution to the environment. All of this supports our key aim of using our solutions to improve quality of life. With our ceramic systems, which are both energy-efficient and visually appealing, and a holistic approach to building design, Wienerberger helps architects to meet future requirements today. The fabulous examples of outstanding architecture on the following pages are proof of just that. The buildings presented here demonstrate the successful symbiosis of using sustainable materials in consideration of ecological, economic and social factors, and are also representative of high standards of architectural diversity and aesthetics.

4 SUSTAINABILITY

A CLEAR COMMITMENT TO SUSTAINABILITY For the past 200 years, Wienerberger has based its successful corporate strategy on a holistic approach and its self-imposed commitment to constantly improving the company’s environmental, social and economic performance.

EMPLOYEES AS A KEY ASSET For a manufacturing company like Wienerberger, the safety, health and satisfaction of employees is, at the same time, a basic prerequisite and a key factor in the company’s success. Even if comprehensive improvements have been made in this area over the past few years, it is important to consolidate and maintain this progress in the long term. RESOURCE CONSERVATION AS A CENTRAL TOPIC Wienerberger has set itself the ambitious goal of contributing to climate protection by increasing energy efficiency and reducing CO2 emissions during production. Raw materials, energy and water must be used responsibly and as efficiently as possible. Where practical, recycled materials are used.

s a leading international supplier of building materials and infrastructure solutions, Wienerberger is aware of its responsibility and deliberately creates sustainable values designed to improve quality of life. The term sustainability has three aspects, ecological, economic and social, which all play an essential role in each of the company’s measures and products. This issue of architectum shows innovative system solutions and projects where planners have set the standards of the future by following this maxim to design sustainable, affordable buildings. The use of innovative, efficient solutions contributes to environmental protection and secures opportunities for future generations. The Wienerberger Sustainability Report 2018 provides a comprehensive presentation of the company’s sustainability strategy and the progress achieved.

02|2019

BUILDING FOR PEOPLE The sustainability report, which, along with the Sustainability Roadmap 2020, serves as an important guideline for Wienerberger, also illustrates these three aspects within four fields of action: employees, production, products and social responsibility.

LASTING VALUE FOR CUSTOMERS As an innovation leader in the industry, Wienerberger continuously works on further developing innovative products and solutions for all areas of application. In 2018, these products accounted for 29 % of total sales. A VALUABLE CONTRIBUTION TO SOCIETY Wienerberger is committed to its role as a responsible member of society. In addition to making donations of materials and participating in joint projects with social partners, Wienerberger cooperates with the non-profit organisation Habitat for Humanity. In the sense of “helping people to help themselves”, these projects aim to create sustainable living space for and with people in the poorest regions of the world. Wienerberger works intensively and continuously to achieve the company’s sustainability goals and to implement suitable measures.

Made from naturally occurring raw materials, ceramic building materials are a byword for sustainability, durability, high quality of life and innovative building.

RESPECTING THE ENVIRONMENT

ccredited laboratories and experts verify the requirements of the eco label, in accordance with recognised international standards. They test three criteria: clean and efficient production, environmental & health protection and sustainability of resources. In order to qualify for the label, products must – among other things – be recyclable, may not contain any substances that are harmful to the environment or health, and must come from sustainable sources. STATE OF THE ART Wienerberger bricks are natural products and meet all the requirements for sustainable construction. Manufacturing plants comply with comprehensive regulations on purity. Special filters and thermal afterburning systems mean that emissions levels are well within the required limits. The use of state-of-the-art burners and heat exchangers,

electronic measurement and control systems, ensures that comparatively little energy is consumed. Abandoned clay pits are turned into natural habitats or recreational sites. Monolithic brick masonry (without composite bonding with insulation materials) can be sorted and disposed of quickly and easily – or recycled. SCIENTIFICALLY PROVEN Following thorough testing of all products from the Wienerberger plants at Hennersdorf, Haiding, Göllersdorf and Apfelberg, the company became the first brick manufacturer in Europe to be awarded the natureplus® eco label. The certification confirms that all the products in the company portfolio are produced in accordance with the relevant requirements, and that Wienerberger fully accepts responsibility for developing energy-efficient, healthy, and sustainable building materials. >

When choosing building materials, sustainability is becoming an increasingly important factor, alongside traditional considerations such as structural stability, fire protection and acoustic installation. The natureplus® eco label, issued by the international association of the same name, helps architects identify certified sustainable building materials. For the first time ever, this quality standard, which is recognised throughout Europe, has been awarded to a brick manufacturer.

ECOLOGICAL 7

SUSTAINABILITY OVER THE ENTIRE LIFE CYCLE If you want to plan and build ecologically, you have to think in terms of life cycles and look at products and processes in their entirety. Any possible impacts on humans, the environment and the consumption of resources should be qualitatively and, if possible, quantitatively analysed.

RECYCLING

RAW MATERIAL EXTRACTION

A large proportion of the overall demolition material can be recirculated with little energy input and reused as recycled building material.

Extraction of raw materials always requires interference with the natural environment; this is minimised as much as possible during operation. Abandoned sites are recultivated, renatured or prepared for reuse.

DISPOSAL Bricks do not release pollutants to the subsurface and therefore can be disposed of at a low cost into (European) Class 2 Eluates. They can also be used as mineral construction waste for mine filling.

DEMOLITION

BRICKS are natural building materials that do not release any pollutants into their environment, whether in the construction of buildings, in their active use phase or in the post-use phase (for example, during demolition). Wienerberger takes into account the entire life cycle (illustrated here by wall construction materials) for a plausible ecological assessment:

The demolition of an object also requires relatively little energy. It is not necessary to separate materials in a single-shell brick construction. For a brick double-shell structure, a simple demolition of the building materials is sufficient.

CONSERVATION â&#x20AC;&#x201C; REFURBISHMENT Brick buildings are particularly durable and therefore have a special intrinsic value. Renovation or restoration work is easy to perform, with less material required.

MANUFACTURING All materials used are free of hazardous substances. Care is taken as a matter of routine that the materials have a positive ecological balance and that aggregates and fillers are biogenic and climate-neutral. Processing takes place under resource- and energy-efficient conditions.

TRANSPORT At all Wienerberger locations, building materials are produced locally. Moreover, the sites at which raw materials are extracted are physically close to production facilities, which results in short transport routes with low energy requirements and low pollutant emissions.

PROCESSING The insulating wall brick technology enables a rapid construction without pollutant emissions, producing low noise levels and comparatively low ergonomic stress on the construction site. In addition, there is no problematic building material waste.

CAREFUL MANAGEMENT OF WATER AS A RESOURCE Heavy rainfall, long periods of drought, heat and flooding are all becoming increasingly common. Without proper rainwater management, these environmental factors can cause erosion and water pollution. Pipelife and Wienerberger develop solutions that combat flooding and, at the same time, make good use of the collected rainwater.

When paving with Passaqua/Aquata, the joints account for around 10â&#x20AC;&#x2030;% of the overall area. This is the minimum requirement for permeable paving.

The underground Raineo® system enables the efficient storage and infiltration of rainwater. The modular Stormboxes can easily be stacked with the simple click-and-stack system.

arge conurbations with large areas of impervious surfaces are especially at risk from the sudden onset of heavy rain. Such impervious surfaces do not allow natural seepage, and drainage systems are not designed to cope with sudden, peak flows. Pipelife has dedicated itself to finding solutions to this problem and developed the Raineo® system for rainwater management. The system is installed inconspicuously underground. It has also been designed to enable planners and users to cope with a wide range of demands, in accordance with the size and purpose of the built area, the degree of contamination of the water or the nature of the soil. CUTTING-EDGE TECHNOLOGY FOR THE ENVIRONMENT Raineo® is a modular – and, therefore, highly flexible – system, which captures rainwater, filters out any impurities, and then, depending on requirements, either releases it slowly to seep into the earth or temporarily retains it in so-called “Stormboxes”. These are stackable, water infiltration boxes with a simple connector system. They store the rainwater so that it is available for further use in sanitation, cleaning or irrigation. The system therefore facilitates the collection of usable water and also the return of rainwater to the water cycle through infiltration, maintaining the natural function of the soil.

NATURAL ECOPAVING Wienerberger has developed another innovative building material for sustainable urban drainage systems in the form of Passaqua (NL)/Aquata (UK). These clay paving stones with spacers for 6 mm wide joints comply with modern planning requirements. Although the paving stones themselves are not permeable, the wide joints allow rainwater to drain away easily. In the space beneath the paved surface, the rainwater is filtered, cleaned, and collected before being released in a controlled manner into the soil or drainage system. This makes it easier to maintain the water table and reduces the risk of flooding. It also reduces the proliferation of algae, moss, and weeds. These clay paving stones have been designed with the unique style, look and durability of traditional paving stones, but are also available in a variety of colours. These premium quality paving stones are strong, durable, and slip-resistant, making them particularly suitable for patios, driveways, paved emergency access routes, public footpaths, cycling paths and car parks. >

NATURAL, HIGH-TECH PRODUCTS Residential buildings need brick and wall systems that satisfy the high requirements for structure, energy efficiency, fire protection and acoustic insulation. With its perlite-filled Porotherm blocks, Wienerberger provides a tried and tested, natural building material with enormous potential, which also helps contribute to combating climate change.

Can be used in walls with a thickness of 36.5 or 42.5 cm and has impressive physical properties: Compressive strength Class 10 Thermal conductivity  = 0.09 W/(mK) Sound reduction index Rw,construction,ref ≥ 48 dB

lients expect innovative buildings with environment-friendly designs, low energy consumption and low heating costs. Planners are therefore encouraged to design solid building structures that are not only economical to build, but also economical to maintain and that preserve their value over the long term.

CLAY, WATER, FIRE AND AIR The perlite-filled Porotherm blocks meet all these requirements. They are made from the natural elements of clay, water, fire, and air. Once processed, the lightweight, perlite volcanic rock forms a natural insulating material. With thermal conductivity of 0.07 to 0.09 W/(mK), the single, m onolithic wall of filled Porotherm blocks does not need any additional thermal insulation in order to meet current energy standards. This also means lower maintenance and construction costs. A further advantage of the solid, but slimline masonry is that it leaves more internal living space. The exceptional properties of the product provide optimum thermal, humidity and acoustic insulation, making it suitable for buildings constructed in accordance with the passive house standard. It is classified as a Class A1 product for fire protection, meaning that it is not flammable. HEALTHY LIVING GUARANTEED Since 2008, Wienerberger has submitted its perlite-filled Porotherm bricks to the German eco-INSTITUT for environmental testing every two years. In 2018 the product was awarded the “mineral construction product” label for the fifth time. The eco-INSTITUT label is a recognised mark of quality for products that have to meet stringent requirements for pollutants and emissions, in accordance with the latest international scientific and research standards.

A VERTICAL, EVERGREEN VISION In central Berlin, there is a living wall that absorbs noise and dust all year round, creating a green oasis for the immediate vicinity. Directly at the roadside, in the heart of the German capital, this verdant façade was created using Wienerberger perlite-filled Porotherm bricks.

he architecture is designed to integrate the building into this growing neighbourhood, without being intrusive. The building is unobtrusive, yet expresses itself in its own distinctive and sustainable way,” says architect Sarah Rivière about her vision for the building, constructed in winter 2016/17, which filled a gap between existing buildings in Berlin’s Kreuzberg district. Together with the client, she designed the new building to be flush with the adjacent buildings, blending in seamlessly, assuring sustainability, and contributing to cooling the urban microenvironment during the heat of summer.

They grow vertically up a support structure that is anchored in the brickwork, ensuring the façade remains green all year round. When residents step out onto their balconies, they are entirely surrounded by plants. There are more green oases on the roof terraces and in the newly cultivated inner courtyard. LONG-TERM SUSTAINABILITY This living wall is made possible by a concealed, ventilated support structure, which is 16 m high and securely anchored in the wall of Wienerberger bricks. The six-storey building has a monolithic structure from the first-floor up, and the multi-storey construction is built from perlite-filled Porotherm bricks. The insulation-filled bricks make it possible to build without additional external insulation, which increases the intrinsic value of the building and permanently minimises maintenance costs.

ENERGY-EFFICIENT AND HEALTHY BUILDING

This e4 brick house in Austria is a successful example of the concept. A well-insulated, ceramic building envelope supplemented by alternative heating systems that combines low energy consumption with low CO2 emissions.

A HOUSE THAT’S GOOD FOR THE ENVIRONMENT The key to energy efficiency is the right combination of building envelope, home and heating technology and the increased use of renewable energy sources, such as solar energy. In Austria, the e4 concept was implemented in the form of the “e4 brick house 2020” with the support of the Austrian Institute of Technology (AIT). The Institute’s energy planners have chosen Porotherm bricks as a single-shell exterior wall with no additional insulation. The solid brick building envelope created with this material has a U-value of only 0.12 W/m2K. The high mass per unit area of the brick walls of more than 300 kg/m2 results in an enormous heat storage capacity in the buildings and ensures a pleasant indoor climate all year round.

02|2019

A HOUSE THAT’S AFFORDABLE In building projects, the time factor is especially important for home owners; the longer the construction time, the higher the costs. Wienerberger has developed two product systems that speed up the construction process and eliminate entire work steps, such as the aforementioned additional external insulation. However, the biggest cost savings are achieved by the e4 house with low operating costs through the use of renewable energy. An e4 household spends two-thirds less on heating, hot water and electricity than the average household.

Efficient energy use (energy), affordable cost (economy), renewable energy (ecology), unique quality of living (emotion): Wienerberger’s e4 concept combines these four principles and stands for a holistically- sustainable building concept that sets the standard for the future and allows planners maximum creativity.

ECONOMICAL 15

A HOUSE THATâ&#x20AC;&#x2122;S SELF-SUFFICIENT The e4 brick house 2020 uses innovative solar house technology. Calculated over the entire year, the house generates more energy than it consumes, making it significantly sustainable by saving CO2 emissions. Innovative solar thermal storage systems guarantee the heat supply is spread evenly over the span of several cloudy days and weeks without fossil fuels. At least 50â&#x20AC;&#x2030;% of the heat demand for space heating and hot water is covered by the use of solar energy. In the cold months, the rest is generated by other alternative heating systems, such as the wooden boiler used in the Austrian example.

A HOUSE THAT SUITS ITS INHABITANTS Sustainable construction does not mean compromising on individual design wishes. An e4 house is not a standardised system house. Architects can realise the individual wishes of the home owners without restrictions due to grid dimensions or pre-defined house types. Thanks to the flexible design options, the e4 house meets all aesthetic requirements. In addition, the strict ecological and building biology standards of the building material bricks enable the realisation of environmentally and, above all, healthy buildings, which improve the quality of life of the residents over generations. The result is an energy-efficient home that exceeds EU building guidelines, significantly reducing CO2 emissions while adhering to the construction budget. The e4 concept is a carefully considered, high quality solution that both meets immediate market requirements and is also a sustainable solution in the long term. >

ALL EXPECTATIONS EXCEEDED In 2015, near Bucharest, the first Romanian family home was completed in accordance with the e4 concept. Three years later, the interim balance is impressive: The concept has surpassed all expectations.

fter the residents moved into the e4 brick house, energy consumption and comfort indicators were comprehensively monitored over a period of 24 months. The analysed data provided evidence that all the parameters in all the rooms are consistent and balanced. The energy efficiency indicators also show that the house has a positive energy balance. “The monitoring data for the first e4 house built in Romania has significantly surpassed expectations,” said Emilia-Cerna Mladin, president of the Romanian Association of Energy Auditors for Buildings (AAECR) and professor at the Politehnica University of Bucharest.

A customised control system and the ability to set consumption targets and to compare them with the actual consumption costs at the end of the month are highly valued by private customers as early adopters. The e4 brick house concept developed by Wienerberger as a residential solution is a smart choice in this day and age. The effect of selected building materials is clearly reflected in maintenance costs,” adds architect Sergiu C. Petrea from Tecto Arhitectura.

A SUCCESSFUL SOLUTION What makes this concept a success is the brick construction and the alternative energy sources, which combine a sustainable

FULL COST CONTROL The owner of this e4 brick house project, who was open to innovative solutions and who equipped his house with a “central brain” for monitoring important parameters and the optimisation of maintenance costs, is also thrilled with his home: “The e4 house was definitely a good investment for our family. We enjoy the comfort, the natural lighting and the steady temperatures in the house, regardless of the season. After moving into the e4 house, our expectations in terms of savings on monthly utility costs were also clearly exceeded as our costs are half those of the previous house,” said Adrian Fortescu, the Romanian e4 pioneer who has a home which saves on resources and energy, but which even so is still architecturally attractive. It ideally meets the needs of a family with two children, with interior spaces that interconnect seamlessly into one another and large windows that flood the rooms with daylight. >

The large window areas fill the rooms with daylight. Everything is controlled behind the scenes by a “central brain”. Thanks to state-of-the-art automation technology, the owners have control over all aspects of living comfort and can closely monitor their running costs.

he goal was to meet all the requirements of a modern brick house construction at an affordable cost, taking full account of maximum living comfort and healthy living. This goal was clearly achieved with the building being the first project to be awarded the BEPOS effinergie 2017 label by the French association EFFINERGIE. France is not only a pioneer in climate protection, but also a country in which perfect design is much appreciated. With this showpiece, CB Architectes highlighted their skills and achieved a symbiosis of form and function, creating a very compact ensemble with a clearly-structured façade accentuating the building’s character with its corners and edges.

On the roofs, 541 m2 of photovoltaic modules were installed. This means that the building complex produces more energy than the residents consume.

A STREAMLINED RESULT The building made with Porotherm GF R20 bricks was additionally insula ted from the inside with expanded polystyrene. The 20 cm thick Wienerberger terracotta brick offers four times more insulation than conventional brickwork and is an economical construction solution. In order to comprehensively combat heat loss, the roofs were fitted with 32 cm glass wool insulation and the ceilings on the various floors were insulated with 5 to 10 cm expanded polystyrene. The windows mainly face the south and feature high-performance double glazing. The high level of energy efficiency achieved this way is also manifested in the low operating costs. In order to improve the indoor air quality, a

Design and cost efficiency are not mutually exclusive. The Safran residence, a 48-unit residence in Ouistreham, Normandy, has become a flagship project. CB Architecte has built an e4 house that is visually striking yet blends harmoniously with its surroundings through the use of terracotta bricks.

FROM A GYMNASIUM TO A SCHOOL IN ONE SIMPLE CLICK Turning a gym into a school definitely would suggest a major demolition project. But that’s not the case in Enschede, where the Het Diekmann vocational school gave one of its gyms a whole new function. The innovative ClickBrick dry stacking system played a key role here, since additional windows could be easily installed where needed, offering maximum flexibility.

A NEW LEASE OF LIFE The flexible ClickBrick dry stacking system made the extensive remodelling of the façade relatively easy. A total of 18,000 bricks were removed to create space for the window frames; these bricks were then in some cases halved for further use. In the end, approximately 6,000 ClickBrick bricks were reused directly in a follow-up project.

02|2019

This shows the immense recyclability of the material, which can be used again and again as an ecological building material with a constant aesthetic quality and a low failure rate. AN EXTRAORDINARY SYSTEM Designers often look for new materials to create an aesthetically attractive look and feel of their very own. At the same time, it is important for the contractors to take into account the costs of material used, its processing, sustainability and upkeep. ClickBrick is a dry stacking system that consists of a larger proportion of bricks compared to conventional bonded and mortared brick systems. They are fixed to each other and to the substrate by stainless steel clips and wall ties. Since the joints do not have to be mortared, there is no efflorescence or staining of the finished brickwork and the system is completely recyclable. Thus, even without expertise in the field of bricklaying or installation and without any special tools, it is possible to build an aesthetically ambitious, colourful façade. The ClickBrick system therefore also provides a solution to the rapidly growing construction industry which goes hand-inhand with the marked shortage of skilled labour in the industry. >

As part of the radical change in use from a gym to classrooms, new façade openings were created to make room for 28 new windows.

efurbishment projects sometimes pose even greater design challenges than new build projects. Renzo Panvello and his team at bct architectenbureau specialise in sustainable building and revitalisation of educational buildings and have combined these two concerns in the Enschede project. Major changes had to be made, especially to the façade. To access more daylight, the architects installed 28 new windows. The façade consists of ClickBrick cladding components, which made the refurbishment work easy. “This brick creates large, continuous surfaces with no horizontal joints, producing an interesting finish. To change the function from a sportshall to classrooms, we introduced several vertical façade openings to add windows. Combined with the beautiful structure of the brick, this creates a wonderful effect,” says Renzo Panvello.

LIVING CONCEPT OF THE FUTURE: TOGETHER The inviting, warm brick façade makes it clear that De Leyhoeve is a place to feel good. Architect Hans Marquart of Marquart Architecten talks about innovative solutions for the future, sustainable design and maximum living comfort in old age.

ur society is getting older. We need innovative ideas for living together and new forms of housing. What challenges does this bring for architects? Hans Marquart: “We have a lot of experience in designing care homes and aging-in-place homes. The human factor is always taken into account. With all our design choices, we try to create a warm and welcoming atmosphere. Simultaneously, the architecture must visibly and invisibly comply with all requirements regarding the quality of the building and comfortable living for its residents. De Leyhoeve is a housing and care estate with 200 apartments, 85 care suites, two restaurants, one café, a lounge adjacent to the library, a swimming pool with a wellness centre, a shop and a day care centre. Many of the building spaces are flexible in their use so that the range of facilities can be adapted to new insights.” De Leyhoeve project is a new concept for a housing estate for older people and people who need extra care. In what way was that challenging for you as architects? “De Leyhoeve was given a very diverse target group with various care needs for their home. It was not to become a nursing home. There was a lot of room for personal wishes in the design, despite the large number of apartments and facilities. We consulted the future residents about the design of the building and its surroundings in various stages of the project. Residents could even try out living in the apartments. This turned out to be very enlightening in discovering the most important needs and expectations of residents. For example, the layout and construction of most of the bathrooms and kitchens were < customised.”

< The slogan of De Leyhoeve is ‘Living comfortably, growing old together’. Where does the idea originate from? “Hospitality is the basis of the design. Hendrik Roozen from the Roozen van Hoppe Group - the developer and builder of the project - came up with the concept for De Leyhoeve several years ago. He saw how a couple in his acquaintance could not continue to live together after fifty years, due to the poor health of the wife. Hendrik Roozen wanted to create an environment in which the couple could continue to live together with various facilities nearby and where their children would feel welcome to visit.”

This idea is also reflected in the restaurant and community areas, which have been designed to bring residents together with children, grandchildren and the younger generation in general. “Yes, definitely. It is important that you can continue to welcome your family and friends for visits, even if you have moved to a smaller home or have become in need of care. Your family can stay the night in one of the guest rooms in the building. The restaurants in the complex are accessible for everyone, including non-residents. De Leyhoeve also has a day-care centre that organises weekly activities for the children with the senior residents, such as storytelling circles and taking walks in the nearby Leijpark. This type of synergy makes living at De Leyhoeve exceptionally lively!”

It took 13 years from the initial idea to the overall completion of De Leyhoeve project in 2016. Why did it take so long? “Most of the time was invested in searching and researching for the best location, the financial resources and finetuning the concept. Marquart Architecten was commissioned to do the design in 2011. Towards the phase of realisation the project went smoothly. The first residents were able to celebrate Christmas 2015 in their new apartments.” How did you incoroporate sustainability into your design? “Sustainable construction depends on many aspects; materialisation, circularity and maintenance play an important role. Bricks are a valuable product in that sense; it is a natural, durable and sustainable material that also offers outstanding comfort.” In your projects you often use bricks as a façade material. What effect does this have on the residents of the house? “Bricks are immediately associated with cosiness and give the building an authentic, classic appearance. For De Leyhoeve we used hand-moulded bricks in two warm-red shades and one brown shade: Terca Dinkelrood Flash, Dommelrood Gereduceerd and Marowijne Rood Zand. The three colours mark the different functions of the building and divide the façade. The deviating building blocks are brown and

slightly darker, like the bases of the linking structure. All the bricks were provided with darker joints, making them a more unified whole. Despite the dominant standardisation, such as the windows and balconies, the façade turned out majestic and lively with a welcoming appearance.” What do you think architects could and should do to promote sustainable and healthy building concepts? “As an architect we have to offer sustainable alternatives to the traditional solutions. The implementation of sustainable solutions hugely depends on your client. With De Leyhoeve we worked with an exceptional client. We were able to complement Hendrik Roozen’s high ambitions and innovative ideas with our experience in architecture design for the care sector. Our team acted as a sparring partner for Hendrik Roozen and contributed many unusual and sustainable solutions. We were on the same wavelength, we just clicked, and that is noticeable in the design of the building.” >

ALL UNDER ONE ROOF Demographic change is an important issue in sustainable architecture. For example, the benefits of several generations living together under one roof and how this can be structurally integrated into an overall concept are demonstrated by the three-generation house in Aalst in Belgium.

oday we live in a world in which, on the one hand, both parents usually have to work and, on the other, older people remain fit and active long after retirement. In the face of this d emographic change, the concept of intergenerational living has become enormously more attractive, whereby it is necessary to integrate this harmoniously into a building structure in which the specific needs of each generation are met. This was also the idea of client Etienne and his family during the planning of a flexible residential complex, which was completed in 2017 and houses people from three generations. The intergenerational compatibility was reflected in the selection of environment-friendly materials, which contribute to the energy efficiency and durability of the home. PRIVACY GUARANTEED Etienne and his children Leen and Chris decided to build four apartments within one complex. On the left and right are the apartments of Chris and Leen. Between the two, a rental apartment was created on the ground floor and can be made barrier-free if necessary. Above that is Etienne’s duplex. “We share a basement with eight parking spaces, but other than that, the apartments are completely separate, each with a separate entrance and private garden,” is how Etienne describes the concept, which allows for proximity without anyone having to forgo his/her personal space.

FUTURE-READY At the request of the family, Architect Patricia Pissens of HAMBLOK-PISSENS used light Terca Agora facing bricks in muted silver-grey. “In order to accentuate the summery colours and the massive character of the façades, the facing bricks were harmonised in different shades of the same colour,” says the architect. To ensure that the house can be enjoyed for generations to come, it has been comprehensively future-proofed and designed for maximum energy efficiency. Solid insulation for the walls, roofs and floors, in combination with the terracotta façade, creates a building envelope that saves energy costs and protects the environment. A type D ventilation system with heat recovery maintains the freshness of the indoor air. Covers on the left side garden façades prevent overheating on hot, sunny summer days. Overall, the apartment complex reaches an energy level of 37. >

As a sustainable building material, the silver-grey Terca facing bricks give the building a stylish and timeless look that will last for generations.

OPTIMUM SPACE USAGE IN THE CITY CENTRE In the middle of Malmö, Arkitektgruppen I Malmö AB has created an extraordinary sports centre. The project was challenging on two levels: the integration of a multifunctional building in the city’s most central location and the creative embedding of the building into the surroundings. Today, the “Hästhagens Sporthall” is a social meeting place for the city’s inhabitants and blends perfectly with the neighbourhood with its natural-looking façade made of water-struck bricks.

he lack of space in cities demands creative architectural solutions. The architect group Malmö AB has designed two sports halls into a site that would normally hardly suffice for one such facility. Due to a unique concept, it was possible to build one hall on top of the other. This not only fulfilled the long-held wish for a new sports facility for the two adjacent schools, but it also created a recreational centre and a meeting place for city residents.

Like the adjacent older buildings, the “Hästhagens Sporthall” has a brick façade. The façade facing the street has a rhythmic character with tall, alternating narrow and wide windows.

ferent age groups use the sports centre during the day. Outside of school hours, it is open to the public and is used for various recreational sports activities and events. There is also a café and a park on the grounds. The outdoor area includes a table tennis and a basketball court as well as a running track.

up a special brick pattern. Diagonally-arranged, protruding bricks and various grouting variants create a distinctive and attractive pattern, reminiscent of a kilim carpet and creating various shadow effects. During the construction process, detailed drawings and large-scale physical tests were carried out on the façade wall in close cooperation with bricklayers and Arkitektgruppe Malmö AB in order to achieve the desired elaborately patterned façade.

FLUID TRANSITIONS WITH THE SURROUNDINGS To help the sport centre fit into the cityscape and the adjacent older buildings, its walls were made of redbrown water-struck bricks W 409 Valmue from the Danish brick plant in Petersminde. To soften the visual impact of this colossus and to give a distinctive character, narrow and wide windows were alternately installed on the street-side façade breaking

A SUSTAINABLE CONCEPT In addition to the wide range of aesthetic possibilities, sustainability along the value-added chain played a major role in the choice of building materials. The goal was not only to plan and build energy-efficiently, but to ensure the longevity of the buildings. With the implementation of “Hästhagens Sporthall” project, the architects at Malmö AB have impressively met this objective. >

OFFICE BUILDING WITH A VIEW Architecture significantly influences the well-being of the people in the buildings. The Quantum Building in Ghent is a prime example of how not only to develop high-quality workspace for employees with optimal views and lots of light, but also how to take into account the sustainability in the use of materials and the energy concept.

QUIET INSIDE, BUSTLE OUTSIDE The architects paid special attention to the acoustics of the offices. Employees are able to work in tranquillity while watching the bustle of city life outside. The Quantum Building is located at one of Ghent’s traffic junctions. The side façades were clad with Koramic Tegelpan 301 clay tiles, impressive not only because of their colour range, but also because of their lightness. They fit perfectly into the local context of the neighbouring buildings. The task of the glass atrium is to flood the office areas with natural light. The goal of noticeably improving the quality of the time spent in the office was completely met by the architects. Thanks to such a concept, the building fulfils the criteria for the BREEAM “Excellent” rating.

The floor plan of the six-storey office building increases by several square metres with each floor. In this way, optimum use is made of the available space and the façade is given a lighter look.

he goal of evr-Architecten was to create a building that, on the one hand, attracts attention through its façade and exterior design, and on the other, creates a perfect working environment. It is divided into three areas: two office buildings and a glass atrium combined to create an H-shaped floor plan. “No matter where people work, they always have a beautiful view and, above all, enough daylight. Not only does that help reduce energy consumption, it also improves the experience and well-being of the workers,” says architect Luc Reuse.

» Designing the façade was a big task for the developer, but thanks to a lot of commitment and appropriate advice an exquisite final result was achieved. It shows that architecture can only be successful if everyone plays their part. « Luc Reuse, evr-Architecten

The façades on the east and west sides are faced with Koramic tiles. The colour transition contributes to the iconic appearance of the building.

BREEAM stands for “Building Research Establishment’s Environmental Assessment Methodology” and is the oldest and most widely used certification system for sustainable construction. BURNING DESIGN Before the clay tiles were selected, various studies were conducted to create the perfect colour gradient. From the ground floor to the upper floors, the colour scheme of the Koramic Tegelplan 301 tiles gradually transitions from blue to red. “The structure that we designed in advance, tile by tile, is based on a repetitive but concealed pattern. You could say that we created a wall from fire and flame,” explains Luc Reuse. >
