Gyproc round table

Providing the right acoustics in a school can go a long way towards improving a child’s education and allowing them to reach their full potential in the classroom was the major conclusion drawn during a roundtable meeting hosted by Middle East Architect.

Held in the Dubai office of Saint Gobain Gyproc the discussion group, which featured architects, engineers, school operators, teachers and experts in materials, looked at ways a good quality of sound in a room can enhance the entire experience of learning.

And it also examined how poor acoustics can inhibit the ability of a pupil to grasp subject matter – and significantly pose a health risk to teachers in the form of rising levels of stress.

Gyproc is manufacturer of modern lightweight, high performance dry-lining and ceiling systems that provide solutions in the areas of acoustics, fire and indoor air quality.

The panel included the company’s senior technical development manager Jason Hird and sector manager Marloes Meer.

From the field of education they were joined by Pete Stapley senior client manager and specialist in design and infrastructure for GEMS Education, Kapil Kapoor chief finance officer for school operators Taaleem and Andrew Turner senior project manager from Hepher who has worked closely with the Swiss International Scientific School.

Representing the design and build industry were Salim Hussain from architect firm Atkins, who has overseen educational projects across the Middle East and in the UK, Maram Sherif, who has been involved in working on schools in Palestine for Lacasa, along with two other experienced school designers, Jason Burnside of Godwin Austen Johnson and Ahmed Abdul Hameed of National Engineering Bureau.

The question “Why do children go to school?” was the first subject to be raised.

The panel agreed that, of course, to obtain an education was the major reason but other factors also needed to taken into account.

Burnside said: “For me it’s not just about the issue of education – children go to school to socialise and I think this aspect is missing in many cases when it comes to design. It’s not just about sitting in a classroom, kinds want to go and play as well.

“You have to be able to facilitate that. Yes, you have this structured learning but children being engaged with each other is equally important.”

Sherif agreed as she pointed out that the whole field was evolving at a faster speed than ever before as technology brings added ways of learning to the classroom,

She said: “Education is now totally different than it was before – it’s about how the children interact, how they get ideas from the atmosphere around. The way they move in the corridors is important and the way they go outside. It’s not about classroom being totally separate from another it’s about the total experience of learning.”

From the field of education Stapley said the design of a school room can help or hinder the teacher and his or her ability to communicate effectively.

He said: “You can teach actually in a barn if you have to.

“But beyond that you want the building to complement the education you are trying to provide. You don’t want to fight your environment you want to work alongside it and the more you can do so the more successful you will be.”

Across the board teachers, operators and design professionals all agreed that clients detailed brief is important for architects and engineers.

And all stated that this includes the field of acoustic, from general noise in the classroom and the rest of the school to specialist areas such as music rooms.

When it comes to classrooms again the panel agreed that the design needs to be different now to that which was accepted as the norm just a few years ago. Members said this was because of greater flexibility in teaching methods becoming the norm.

Stapley said: “It is not about rows of desks in a classroom any more. It is much more about smaller groups and a teacher who can move around the room.

“Children are seated in a classroom maybe in groups of four or eight, They might then go to a more formal seated row environment but then they will break out into smaller groups again.

“I want my classroom to be put together in such a way that I can have a different learning environment and I want my teacher to be mobile. As well I want to be able to change my learning environment by changing my seating arrangements so I can give my teacher different focus points throughout the room.

“They could be teaching from the front and then from one of the walls and this means you can manage the acoustics in a room to a certain extent. But that is not to say we shouldn’t be getting the acoustics right in the first place.”

Leclercq asked: “But is that moving around because eth attention span of kids has lessened through the years? We are very much in a you tube-style environment with one and a half or two minute clips otherwise they will just lose interest.”

Stapley replied ”I don’t know whether the attention span has reduced appreciable But we are more cogniscent that attention spans can be shorter so lessons now – even though they might be an hour long – are broken down into manageable bite-sized chunks and activities changed so that you re-awaken wats going on.

“And the more your environment – in terms of design – can help you do that the more effective the learning is. You can use your building as another teacher. It is part and parcel of the whole thing – it is one of your learning tools.”

The panel agreed that, obviously, clients and design professionals have all been to school. But the members pointed out that in many cases their experiences are out of date because it was a long time ago.

The panel then watched a video – part of the TED series which focussed on the effect of poor acoustics in a classroom

It revealed that children seated in the fourth row of a classroom miss 50% of the words the teacher is saying and this has a profound effect on their education as they need to fill in the blanks themselves rather than be able to process the information with no distractions

A study has revealed that 16% of children have some sort of impairment (permanent damage or ear infection) while 33% have problems focusing – such as hyperactivity – or are introverts by nature.

And of particular importance in the UAE many children are being taught in English – which is not their first language.

The panel also heard of the effect of poor classroom acoustic performance on members of a school’s staff. Teachers need to be heard and speech levels vary in between 40 decibels to 80 So a figure of 65 is considered satisfactory.

If this means they are not being heard, a medical study shown  in the video revealed  health is severely affected  with conditions such as stress, high blood pressure, and even heart rates rising possibly leading to a  heart attack.

Meer pointed out that even if the acoustics in the classroom are fixed there will most likely be  noise coming from elsewhere – from outside and from the corridors. So the issue of reverberation through floors and ambient sound in the background also need to addressed.

Hameed said: “In previous time acoustics were not such an issue as the classrooms were smaller and around 40m2 now we are designing them to be   60 and 70

“If we don’t consider acoustics and incorporate them into the project budget there will be a major problem>”

Kapoor posed the question: “What about sports facilities, you have to decide where they should be placed in relation to classrooms.”

The panel agreed there needs to be a discourse between architects engineers, contractors clients, and education professionals at an early stage to ensure that when a school is being built the right result is obtained.

But members accepted they were up against the issue of costs and budgets.

Burnside said: “When it comes down to designing there is always the question of what disciplines can be removed. When you come down to budget they may not allow us the luxury of such things as acoustic lining.”

All agreed that sharing information was a way forward.

Kapoor said: “We have a huge amount of documents on all sorts of factors which were important when it comes to designing schools because of the number of educational projects we work on.”

Leclercq said:  “If you put that all together it could form a design guide.”

Shapley said GEMS has have put together a similar document and it does cover acoustics “but I wouldn’t say it goes into every detail” he added.

Value for money is key said panel whose members all agreed that false economies created huge problems in the operation of a project – and more importantly could limit the educational value of a class for children and so inhibit learning.

Hird said: “When it comes to the learning environment for children – being able to hear what the teacher is saying is key.

“It’s imperative and not withstanding the modern methods of teaching, such as a teacher moving around, that doesn’t solve the problem. It is something which needs to be addressed from as early a stage as possible and having a proper acoustician as part of the design team can be of huge benefit.

“And – as we have all agreed – it is not just about the project. It is about the education of future generations and that is vital to the well-being of any society.”

He emphasised that to remove the acoustics package from a project in order to cut down on expenditure is certainly not value engineering and the panel agreed saying that to go back and tackle the problem later would cause even greater costs to be incurred – disrupt the smooth running of the school and ultimately affect the schooling of pupils.

Burnside said: “Dubai range of demographics and everyone needs to have an education. So acoustics is not the highest priority – it’s getting an education or not.

“There is an issue for parents If they want to pay extra money for a better environment – asking will my child get an A* or go on and get a good degree? That is a choice that they face”

Hussain said that it was up to the design and build business to ensure they place as high a priority on design excellence as possible.

Turner said: “If it is left to the authorities then they will establish the mimimum standards and settle them but we are trying to hit better than minimum.

“So that’s why the operators are key. GEMS for instance, they have people like Peter who sit down and decided what the standards should be and then inform their professional teams this is what we want you to achieve. Without them we would just have investors seeking what the minimum standards are and just reaching that level.

“If that was the case we would end up with a whole load of minimum standard schools and that is not what iit is all about>”

Hussain then asked the question “What is value engineering and what is cost cutting? if you do not make that distinction you are not doing the best for the project,”

The panel debated the issue – do you cut costs to save money but be less effective – do you spend slightly more to get a slightly better result or do you invest by a few more percent  and  get a result  around three times better than the minumu standard originally set.

Hird said: “You can add value is so many ways and it’s not just all about cost sometimes people will go for slightly cheaper products but they are not fit for purpose. So in the end it is the project – and ultimately the staff and pupils – who will suffer.

“Investing slightly more in as important a subject as education will have increasing benefits to the future of society as a whole.”

The panel agreed that children now at school will take on jobs which have not yet been invented – such is the rapid growth of technology .Members used the Ipad as an example of a device which had not even been envisaged at the beginning of the current century yet is now in common usageme.

So members said classroom design will need to reflect that fact that teaching methods – and the subjects being studied – will be an area of rapid expansion and change.

Stapley said: “Classroom design needs to be flexible enough to embrace technologies so we don’t have to rip everything out and start again.”

Hameed said that design solutions and material forms an important part of this issue.

“If you used dry wall rather than heavy concrete blocks interior panelling can be moved around and a classroom reconfigured. This means less cost less time wasted and a room which can be made fit for purpose for a wide range of different uses.”

The panel agreed that in school auditoriums this is a vital need, as one day there might be a basketball match being played while the following day there may be a concert staged and then the room might be used for an exam.

So flexibility in design must be able to accommodate all these factors and more the panel agreed.

Finally members agreed there needs to be a discourse between architects engineers contractors clients and education professionals at an early stage to ensure when a school is being built the right result is obtained.

“It’s all about those first few thoughts,” said Turner “They will dictate how the project is going to go.”

“Everyone wants the best for the children – that is what schools are about,” said Hussain, “As professionals that is what we need to ensure.

“Remember the kids. They spend hours of their lives in these places and saving a few hundred dirhams here or there is not important. It’s about educating future generations, future leaders of the UAE and wherever else. This should be the main consideration, not anything about commercial concerns.

“We  have to ask – what is the benefit in providing an education to us all as a society?”
