ACOUSTIC PERFORMANCE IN SCHOOLS

In contrast to many other sectors, there is detailed acoustic performance guidance for educational buildings. Here Adrian Whitefoot, Technical Services Manager at Kalzip, looks at the requirements of Building Bulletin 93 and how the correct specification of building envelope solutions can help achieve these.

Ensuring good acoustics and minimising levels of noise in school environments is essential. A growing body of evidence has shown the impact of noise on academic performance and cognitive development. For example, a recent study from the Barcelona Institute for Global Health found that higher levels of traffic noise caused slower development in memory and attention among children aged 7 to 10.

The main source of legislation for acoustics is Approved Document E of the Building Regulations, and in particular section E4, which specifically relates to acoustics in schools. For guidance on achieving the required acoustic conditions, Approved Document E refers to Building Bulletin 93 (BB93), the guide for acoustic design published by the Department for Education. While section E4 of the Building Regulations does not apply to colleges and universities, the acoustic recommendations provided in BB93 may also be desirable in these environments and therefore can provide a design standard.

Building Bulletin 93 sets limits for the level of ambient noise in rooms and spaces within a school based on how it is used. For example, the limit in classrooms and general teaching areas in primary and secondary schools, including those used for music and drama, is 35dB LAeq,30mins for new buildings and 40dB LAeq,30mins for refurbished buildings. Higher limits are set for sports halls, dance studios and swimming pools, while lower limits are given for teaching spaces for students with special hearing and communication needs.

Noise pollution can come from a wide range of sources, especially in school environments. External sources include aircraft, traffic, rain impact, noise from playgrounds and outdoor sports, and sound transmitted from nearby school buildings. Internally, impact and airborne sound from students and teaching activities can be transferred between floors and through walls.

Noise reduction can be easily achieved with the use of the Kalzip Accoustic roof.

There are a number of measures that can be implemented in the specification of building envelope systems to improve the acoustic performance of both new build and refurbishment projects. Different insulation materials will have varying acoustic properties but one of the most effective methods for increasing sound insulation of roofing and facades is to increase the mass of the system. Its performance is governed by the ‘mass law’, which states that the sound insulation of a solid element will increase by approximately 5 dB per doubling of mass. With metal roofing systems this can be achieved by adding different densities and thicknesses of mineral wool or rigid slab insulation. Alternatively, for higher performance scenarios, various thicknesses of cementitious board can be introduced as part of the façade or roof build up. As a built-up solution, aluminium roofing and façade systems offer this flexibility to tailor the specification to meet the acoustic requirements.

In addition, acoustic and dampening membranes can also be used to increase sound insulation. For example, to reduce the sound of rain noise, an anti-drumming membrane can be bonded to the underside of an aluminium roofing system to achieve approximately a 6 dB reduction in sound intensity.

Controlling sound within teaching spaces must also be considered carefully when designing educational facilities. Excessive sound reverberation within a classroom can distort speech and make teaching and communication difficult. Building Bulletin 93 provides guidance on acceptable reverberation times (RT) depending on the intended use of the space. For example, for a new build nursery room or general purpose primary school classroom it is ≤ 0.6 seconds. In contrast, the same type of teaching space in a secondary school would only need to achieve a RT of ≤ 0.8 seconds. The correct specification of roofing and façade systems can help to minimise excessive reverberation as well. Perforated liners and structural decks can be introduced as part of the roof build-up to diffuse sound where improved sound absorption performance is required.

The Kalzip Accoustic roof is based on the proven Kalzip technology with the same flexibility.

Achieving the optimum specification to ensure acoustic targets are met alongside all other building performance and design requirements can be complex. That is why it is important to partner with a roofing and façade system manufacturer that can offer a wide array of solutions as well as technical support services. Leading manufacturers, such as Kalzip, will be able to use laboratory test reports and data from previous projects to provide specification guidance and assess the performance of a proposed system.

Ensuring the acoustic performance of school buildings is essential to provide an environment that supports learning and development. Building Bulletin 93 provides detailed guidelines, which the correct specification of building envelope materials and systems can help achieve.

KALZIP – „Pavilion Scheveningen“

Architecture on the Scheveningen waterfront

The Vision.

Scheveningen is an internationally known vacation destination and not only the largest but also the best frequented seaside resort of the Netherlands. Its endless beaches and the spectacular redesign of the beach boulevard in 2015 make this town worth a visit throughout the year. At this special place, the Dutch architect Wim de Bruijn has designed a unique pavilion, whose design and functionality has no equal. It opened to the public in 2021.

The impressive building at the end of Noordboulevard’s beachfront combines ‘the elegant shapes of the Morales-Boulevard with waves and shells at the beach, all together frozen still in a white composition of glass and steel’ describes de Bruijn of the new boulevard’s icon. At first, the roof shape of the wire frame model seemed to be impossible to construct but perfect teamwork by many different specialists made it possible.

Engineering:

The foundation of the exceptional 3D-shaped roof construction is Kalzip’s X-tail profile sheet. A vertically adjustable pipe construction made it possible to follow the designated contours of the standing seam roof cladding. This led to all the profiled sheets having different measurements, so the experts on site had to follow a strict installation plan which was provided by Kalzip. The steel substructure of the standing seam roof cladding prevents noise pollution from penetrating outwards and adapts to the wind movement on site

That was a very important subject to consider beforehand, since the pavilion is located precisely at the noise location of beachfront and boulevard (from stone to dune). The spectacular round shape and the aluminum roof cladding make this building an impressive eyecatcher from every direction.

Sustainability:

The three-storey building consists of a basement, a main floor with a terrace and a first floor with another huge terrace, that had to be ‘cut off’ the main roof to gain an exclusive elevated view onto the beach and the boulevard. But not only from the terrace you can enjoy the spectacular view, also through the insulated glass windows from the interior of the house, the beach feels as close as it gets. Daylight illuminates the main floor almost self-sustaining and contributes to the fulfilment of de Bruijn’s vision.

The pavilion has an excellent thermal insulation value (U-value=6), based on the combination of PIR and fiberglass systems that were used insulating the roof construction. The long-lasting aluminum consists almost fully of recycled materials and classifies as sustainable metal. The Noordboulevard covers most of its energy demand per solar panels which are also connected to the pavilion.

Teamwork:

To make de Bruijn’s vision a reality, the technical crew, Felspartner B.V. (Kalzip PremiumPartner) and Kalzip had to work as a synchronized team from the very beginning. It was crucial, that every specialist could bring in his experience as they began working with 3D models. A construction site at beachfront always brings its own challenges that could only be handled with a perfectly organized and well attuned team of experts. Teamwork, combined with skilled craftsmanship and communication at eye level led to an innovative and sustainable building, that blends in in its sensitive surroundings, connecting the elements of ocean, beach and water trough state of the art architecture and efficiency.

Kalzip – There’s no way to do it better.

Refurbishment of Inverurie Community Campus

The Inverurie Community Campus in Aberdeenshire:
A modern meeting point for pupils and citizens

 

Kalzip roofing and cladding package protects £56M Inverurie Community Campus

The team responsible for the £56 million redevelopment of an Aberdeenshire community campus has employed a comprehensive selection of Kalzip® profiles in different colours and widths to complete the roof and cladding of the major structures: including the main teaching block, swimming pool and sports hall; subsequently winning the Development of the Year (Public Buildings) category at the Scottish Property Awards.

The showpiece of Aberdeenshire – the freshly refurbished Community Campus for the entire community 

An inpirational place to learn

Designed by Halliday Fraser Munro and built by main contractor, Robertson Construction, the Inverurie Community Campus project also included a £3 million sub-contract for the roofing and cladding work, which was delivered by specialist installer Curtis Moore.

Replacing existing premises, the new school features 73 classrooms and labs, along with sports facilities, a large dining hall and kitchen, and a conference room. It can accommodate 1,600 pupils – making it one of the largest schools in the North-East of Scotland – and provides a range of amenities for the wider community, including a six lane pool and training pool, outdoor football pitches and a fitness suite.

The largest school in the north-east of Scotland and meeting point for sports enthusiasts 

An array of products that perform

Amongst the Kalzip® profiles supplied to Curtis Moore for the contract were 65/400 and 65/500 flat panels in the 0.9mm gauge in two tones of bronze for the facades; as well as 65/500 1.0 mm gauge material featuring a PVF2 finish to the roof. There were also 35/200 perforated as well as plain liners. Materials for the vapour control layer installed under special acoustic insulation included clear membranes, foil and tapes.

The irregular facade design fits perfectly in the surrounding and has an almost organic wooden look 

Expertise to ensure the current fit

One of the key design challenges which Kalzip’s technical department helped the project team address was the setting out of the windows; the solution to which involved employing three different sheet widths to achieve the most economic use of material, as well as creating aesthetically attractive elevations.

Standing strong against the elements

The Kalzip® standing seam roof and cladding panels with their PVF2, stucco embossed and other finishes offer outstanding weather performance and durability, well able to withstand the Scottish climate throughout a long, low maintenance life. Kalzip® duly provided a 25-year guarantee for the completed installation, though the system will deliver a minimum 40-year service life.

Appearances are deceptive: the facade has to stand more than sunshine in the scottish climate

Sustainable production halls at TRUMPF

New buildings on the company premises of TRUMPF near Stuttgart:
Industrial buildings as electricity supplier

Large module for small technology. This was the theme of Kalzip’s involvement in the completion of the Trumpf manufacturing halls in Ditzingen. Three halls were fitted with Kalzip roofs, which combine a modern design with an integrated solar roof solution.

The company premises of TRUMPF in Ditzingen near Stuttgart

Playing with angles and heights

TRUMPF has been providing ready-made solutions in the fields of machine tools, laser technology, electronics, and power tools for almost 100 years. The architectural firm Barkow Leibinger from Berlin provided the design for the newly constructed buildings. Instead of the usual simple flat roofs, the architects opted for dynamic-looking roof construction. Slightly pitched gable roofs and butterfly roofs with slopes of 5° each alternate three to four times per hall and form a straight line at the ridge and eaves when viewed from above.

The design from the Architekturgesellschaft Barkow Leibinger is playing with contrary angles

Active use of roof space

In addition, Kalzip contributed to a special feature with its roofing components. In contrast to other manufacturing halls, the new buildings in Ditzingen were largely covered with solar panels, which contribute to sustainable energy generation. The architects’ desire to achieve the highest possible utilisation of solar modules with a homogeneous surface area presented both the manufacturer Kalzip and the fabricators with challenges.

Appearance and function are going hand in hand

 

Practical challenges in transport and assembly

A further challenge was the special production in excess length. For the building project in Ditzingen, profiled sheets with a length of up to 28 metres and with up to 12 solar modules on one profile were created – making them the largest AluPlusSolar profiled sheets ever produced and delivered by Kalzip. The transport was correspondingly difficult: loaded onto an overlength lorry, the profiled sheets were permanently kept under surveillance by an escort vehicle belonging to the haulage company. In addition, a police escort accompanied the lorry on the route from the Kalzip plant in Koblenz via the motorway to the construction site in Ditzingen. Kalzip profiled sheets were installed as the final layer. Due to roof permeations and transitions, the sheets were produced in different lengths accordingly.

To be able to connect the solar modules and with the inverter, the fitters had to install each panel individually, which required a special effort from the team: « We have installed Kalzip systems before, but never on this scale. Placed on the standing seam of the previous profiled panel, around 11 installers had to hold the panel at an angle so that the electrician could connect the wires underneath, » explains Tobias Brohmann.

The dimension of the solar modules as a challenge on the construction side

Enough electricity for a whole village

But all the hard work paid off. The highest possible utilisation of solar panels was achieved. Except for a few centimetres of edge strips and at roof intersections, solar panels have been installed on the roof surfaces of a total of about 15,200 m2 over the entire area. A total of around 10,000 panels achieve an output of 1,138.5 kWp – an amount of energy to supply 100 one-family houses with electricity – and thus ensure sustainable and ecological energy generation.

The new building of Tenerife Airport has a Kalzip Standing seam roof

The Tenerife South Airport’s connection building is expected to increase the airport’s size by 50 per cent

In 2018 the Government of Tenerife decide to extend the Island’s Airport. For the amount of 53,9 million euros the new connection building was planned with Casadevall & Sayeras arquitectes commissioned to design the building. The new building will house, as a priority, security control filters and provide continuity from the gates to boarding lounges and the departure and arrival halls.

Kalzip is the specialist for airport roofs

In the past, architects have repeatedly relied on Kalzip for the planning of airport roofs. As a result, a certain know-how has developed at Kalzip over the years. This know-how was the key to success when it came to the tender for Tenerife Airport.

The curved roof, which shelters the entire interior space, is the main element of the project. It is composed of curved lattice beams and a light deck-type slab, complemented by the metallic finish of the roof based on aluminium standing seam Kalzip system, with a low reflective patina finish surface. The build-up utilises a double layer of rock wool insulation and Kalzip polyamide E clips to provide thermal and acoustic properties according to the project specification.

In the end over 11,750 sqm of Kalzip 65/333 in Kalzip AluPlusPatina Nature mill finish surface were installed on the new junction building.

Special design for a Junction Building

“We do not know of another passenger terminal in which a new ad hoc building has been designed basically to contain the security controls. We are talking about approximate dimensions of 150 meters long by 95 deep. Our proposal aims, by means of a soft design « gesture », to encompass, cover, the entirety of the new space. We achieve this with an arc segment with a circumference of radius 150 meters. With this formal strategy, the façade surface is minimized, which we envisage entirely glazed. Thus, from the new departure lounges and the adjacent circulation space, it is possible to continue enjoying the marvellous maritime profile.” Said Dolors Sayeras, one of the projects leading architects.

Linear transverse skylights emphasize the curved character of the roof and direct passengers in their transit from the ground side to the air side, achieving a diaphanous and light interior space, diffusing the light evenly thanks to a semi-white and white false ceiling permeable to vision.

Kalzip Roof System offering Sound Performance over Aberdeen Event Complex

A high acoustic performance was needed for the new Event Complex in Aberdeen

Able to host international conferences, industry leading exhibitions and live performances, The Event Complex Aberdeen (TECA) opened in 2019 to wide acclaim for both its facilities and the structure’s stunning appearance: attributable in part to the choice of a roof design featuring Kalzip® standing seam profiles.

In fact, the manufacturer helped evolve a high-specification build-up which – once current restrictions allow concerts and conferences to resume – will provide an acoustic performance that can prevent sound break-out or any disruption from what is an unusually noisy setting.

The TECA is built for a capacity of 15,000 people

Aberdeen City Council has hailed the development as being expected to boost the country’s economy by £63 million a year. The main building, constructed at a cost of cost £333 million, has already hosted acclaimed bands and crucial business conferences, most notably the Offshore Europe Expo in 2019.

Representing a key element in the council’s long-term strategy, the extensive structure was designed by the highly regarded Keppie Architects and built by Robertson Construction. In addition to preventing noise disturbance from music events, the facility’s proximity to Aberdeen Airport, with its numerous commercial flights and helicopters ferrying workers out to the North Sea oil and gas platforms, further raised the bar on acoustic performance for the 15,000 capacity arena, and led to the involvement of Edinburgh based specialist consultancy, Sandy Brown.

Appraising the acoustician’s involvement, Sandy Brown stated: “During the design stages, we highlighted the need for significant areas of sound absorbent treatment to control reverberation in the arena and conference halls, and undertook computer modelling of various early design options. Then as part of the commissioning, a large arena sound system was used to simulate worst-case amplified music levels in the arena and main conference halls and the noise levels were confirmed to meet the criteria at all nearby dwellings.”

An Outstanding sound reduction was the main key for Kalzip

Kalzip® was able to supply the project team with a wealth of technical data and acoustic analysis from other high profile projects it has been involved with across Scotland; including the SSE Hydro Arena in Glasgow.  This therefore enabled the manufacturer to work with the architects and acoustician on evolving the ideal roof build-up to control both the noise of performances and the sort of low Hertz reverberation generated by helicopter rotors.

In order to achieve an outstanding 55 dB sound reduction figure, the roof features a bespoke Kalzip® system comprising 14 separate components, including rock mineral wool slabs for acoustic attenuation; while the 1mm gauge, 65/400 profile version of the manufacturer’s world renowned aluminium roofing system, with a stucco embossed finish, weathers the system.

The manufacturer’s ability to offer site rolling further facilitated the installation of 100+ metre lengths of the profile direct onto the roof structure, thereby avoiding the need for overlaps anywhere over the arena and enhancing the weather resistance of the envelope.

Kalzip® duly provided a 25 year guarantee for the completed installation through the system will deliver a minimum 40 year service life. With more of the material employed for cladding walls and the other roofs to the exhibition complex, a total of 27,000 m² of the 65/400 stucco embossed profile were supplied for the contract: the success of which has led to further work with Robertson Construction such as at Bertha Park in Perth.

 

The walk to the site itself is also very impressive. – © Kalzip Ltd

 

In addition to the technical advantages of the new TECA, the architecture of the project should also be emphasised

The 7 stations of the Orange Line in Bangkok – Kalzip supplies roofing sheets

Bangkok’s metro network is getting a new rail line.

Rendering of the Overground Metro Station – © Wikipedia CC

In 2017, the foundation stone was laid for Thailand’s new mega project. A complete metro line is to be built within seven years. At Easter time, the new MRT Orange Line is scheduled to open in 2024.

New construction and extension to the existing metro network

In total, the Orange Line is to be 35.86 km long and have 29 individual above-ground and underground metro stations. The first phase of construction is 23 km long and includes 17 of the 29 stations. About 14 km of the line will be underground with twin single-track tunnels, and about 9 km will be overground. The line will then start at the Taling Chan underground station west of the city centre, cross under the Chao Phraya River near the Somdet Phra Pin Klao Bridge and will connect to the MRTA depot located at the authority’s current office building. Further east, the planned Yellow Line is crossed at Lam Sari station. At Khlong Ban Ma station, the line merges into the elevated section and finally ends at Suwinthawong station.

Start of Kalzip installation in January 2021

A complete roofing concept was planned for the sections of the elevated railway line. For the 7 overground stations, Design Concept Co. Ltd planned with a hard roofing that should be sustainable and durable. It quickly became clear that a Kalzip roof was the right choice. The first roofing sheets for the first of the 7 stations were delivered in January 2021.

Panama Cruise Ship Terminal

Kalzip covers the new cruise ship terminal in Panama City.

With a total area of 20,000 sqm, the new Panama Cruise Terminal is to become one of the most important cruise ports on the tourism routes of the American Pacific. Thus contribute significantly to the growth of tourism in the Republic of Panama. The planned project by the architectural office MALLOL Arcitectos allows berthing of two cruise ships with up to 5,000 passengers each. Two large ships with a length of up to 380 metres/1,247 feet each can dock at one of the two piers.

The terminal itself is located directly on the Amador Causeway in Panama City, near the Pacific entrance to the Panama Canal. The construction of the terminal will enable a new 14-day South Pacific route for cruise ship operators.

The heart of the terminal is the large roof with more than 16,000 sqm of Kalzip 65/400 aluminium profiled sheets with a material thickness of 0.9 mm. The special feature is the Kalzip profiled sheets coating (PVDF in the colour Dark Pastel Green Metallic). This coating contributes to an architectural highlight of the terminal.

 

The roof structure of the cruise terminal is designed as a triangle. In aerial view the entire architecture, including the two piers, looks like an arrow.
