Acoustics in the workplace – What’s the “new normal”?

Rebecca Hogg
Acoustic Consultant, BSRIA

Wooden blocks spelling 'new normal'

There is no denying global events this year have turned every aspect of our lives upside down, and as we all start to try and get back to normal while lockdown restrictions ease, we realise it is a “new normal”.

Workplaces have changed, some almost unrecognisable from before, and there is a myriad of requirements to consider beyond the essential health and safety measures. Occupant wellbeing was a prominent consideration prior to lockdown, and this included provision of a good acoustic environment, but how are new COVID-secure workplaces affecting the acoustic environment?

For many years there have been acoustic standards and guidelines on internal noise levels in offices, determining sound power levels of building plant, and predicting the sound absorption of materials. Well designed open-plan offices have allowed large groups of people to collaborate and communicate effectively, and noise regulations have ensured factories and construction sites operate without disturbing neighbours.

In recent months, the workplace has been turned on its head. Following government guidelines many people began working from home. Suddenly the familiar hum of the workplace was replaced in some instances with squabbling children or impatient pets, and if you live alone maybe unwelcome silence replaced your usual face-to-face conversations.

As people are gradually allowed to return to a place of work, new COVID-secure offices have changed the acoustic environment. The installation of screens, the partitioning of open plan spaces, wearing of face coverings, and a lower level of occupancy have created acoustic challenges. For example, speech intelligibility is affected by the reverberation time of a space. Fewer people and more reflective materials, such as plastic screens, will decrease the sound absorption and increase the reverberation time, resulting in poorer speech intelligibility.

Building services have been specified, installed, and commissioned for a particular set up of a workplace layout and building occupancy. If a space is divided into individual offices to allow for social distancing, then the building services provision also needs to be reconsidered. Changing the control settings of a system will have an impact on the internal noise levels and subsequently on levels of occupant annoyance.

Not everyone works in an office, so, what about situation in different workplaces? Factories, shops, and construction sites have been redesigned to allow for social distancing, and often operating hours have been extended to allow for shift patterns, potentially increasing noise nuisance for neighbours.

In these environments the noise levels are also often higher and communication between people can therefore be harder. People working further away from each other and wearing face coverings will inhibit successful communication and influence performance, and if someone must shout to be heard does this have the potential to spread virus droplets further? There should also be consideration of the highly overlooked 12 million people in the UK who suffer from some level of hearing loss. Being unable to lip read because someone is wearing a face covering, or unable to hear the conversation over a bad video conferencing link is incredibly frustrating and isolating.

The acoustic challenges within a COVID-secure workplace may seem overwhelming but there are several simple solutions. Firstly, identify noise sources in the workplace and maintain them appropriately to minimise background noise.

Something as simple as cleaning filters inside a fan coil unit can increase airflow and capacity, meaning the fan speed can be reduced and subsequently the noise level.

Secondly, examine acoustic specifications of any new products being installed – ask to see test reports and consider how a new product could influence the acoustic environment.

Finally, consider the occupants of your workplace and how they use the space. Tailoring the acoustic environment to the needs of the occupants can increase productivity, decrease annoyance and overall improve the wellbeing of all. The focus on workplace safety is paramount, but long-term considering other design parameters, such as the acoustic environment, will ensure workplaces not only survive but thrive.

The importance of investigating failures in building services

A study from the UCL(1) revealed that building failures may cost the UK construction industry £1bn to £2bn every year. This was a conservative estimate made in 2016, based on 1 to 2% of the total value of construction.

As of March 2020, the Office for National Statistics has estimated the total value of all UK construction works to be worth £12.7bn, 68% of which is for new buildings or the repair and maintenance of existing buildings. This would give an estimated cost of failure between £85m and £170m, of which building services would account for a high proportion.

Types of failures in building services

Bathtub curve regarding types of failures in buildings
Bathtub curve

The typical pattern of failure arising against time is shown by the well-known bathtub curve. The curve is divided into three segments: an infant mortality period, usually marked by a rapidly decreasing failure rate; a random failure period, where the failure rate continues at a

The first period is usually detected during the defects liability period after a project is handed over.

The second period would happen during the operation of a system, and failures may occur due to inappropriate operating conditions or maintenance regimes.

The third period is when the system is reaching the end of its life. Failure could be imminent and there should be little or no surprise in this happening.

Importance of investigating these failures

Showing house made of money i.e. there is cost in everything, so always investigate to prevent repetitive failures
There is cost in everything: Always investigate to prevent repetitive failures

There are various reasons why every unexpected failure should be investigated. Below are some of the key ones:

  • Insurance purposes. Insurers may require an independent evaluation of the failure and investigation of its possible cause to identify possible fraudulent or malicious intentions.
  • Cost savings. Too often, failed components are replaced without investigating the root cause. Without understanding the origin of a failure, it is not possible to prevent its re-occurrence. Repetitive failure and replacement of components could add significantly to the operating cost for a building or estate.
  • Health and safety. In May 2009, a lift at London’s Tower Bridge tourist attraction suffered a vital mechanism failure that sent it falling with 9 people in it, four of whom suffered bone fractures. The malfunction was caused by the failure of a counterweight mechanism. The accident investigation by the HSE revealed that there had been several previous component failures with the counterweight mechanism, and the components had been replaced without proper review, and with no investigation into why they were failing so early. Tower Bridge was ordered to pay a total cost of £100k, and the HSE concluded that, had there been a proper review into the counterweight mechanisms, the catastrophic failure of the lift could have been avoided.

Construction quality could be catching up with other industries

This blog was written by Lynne Ceeney, Technical Director at BSRIA

If you order steak and chips at a restaurant, but the waiter delivers hake in strips, you would be rightly annoyed. Instinctively you blame the waiter, but it could have been a problem with the ordering software, a misreading in the kitchen or just the wrong dish being picked up.  Whatever, you would send it back – it is not what you ordered.   In new buildings, this happens all the time.  Poor communication during the briefing, design and construction process, and poor handover and operation leads to a building that doesn’t deliver the performance the client thought they had ordered in the first place.  Unlike a dinner, it’s not practical to send a building back and wait for the one you asked for to be delivered.  Instead extensive snagging lists, expensive defect resolution and defensive “best we can do” fixes by the facilities team are often used to try and get the building closer to its intended performance – and “closer” is usually the best that can be achieved. The owner and occupier end up with a disappointing building, and the designers and construction company are left with a disappointed client.  The blame chain spreads, and it’s hard to pin down the fault.

The impacts run way beyond disappointment.  Occupier discomfort impacts staff retention, and the increased societal focus on wellbeing indicates that employees will expect higher standards from their place of work.  Poor commissioning or confusing controls mean building systems that don’t work properly and need constant attention or premature replacement, as the uncomfortable working conditions impact on worker productivity.  Inefficient buildings use more energy requiring more cash and causing more carbon emissions.  In fact buildings contribute 37% of UK green house gas emissions from gas heating, and consume 67% of the electricity used in the country.  It’s no wonder that larger investors are taking much more of an interest in the sustainability and performance of buildings rather than just the upfront capital cost.  Good buildings are an asset, poor buildings become an expensive liability in terms of operating costs and void periods. Competitive property markets compound this situation.

With a typical building having a life expectancy of at least 60 years, we are building in problems for this generation and the next.  We’re not great at mass retrofitting, (and the high demand for additional building stock means a capital, skills and material shortage) so we need to get it right first time.  Effective management tools with this aim abound in other sectors, for example DRIFT, (Doing it Right First Time), Six Sigma, LEAN and Zero Defects.  We see the approach being used in food manufacture, car making, pilot training, and patient healthcare, to name but a few sectors.  So what about construction?

Soft Landings is the equivalent tool for the construction sector.  This tried and tested process was developed to help to produce better performing buildings – not necessarily exceptional in performance, but buildings that deliver in operation what they were designed to do in the first place.  Getting a building right requires a shared focus on operational performance of the building right from the start, and throughout the design, construction and commissioning process.  The use of Soft Landings delivers this shared focus, improving communication and collaboration between all parties in the building delivery chain.  It helps everyone to avoid the pitfalls that diminish operational building performance. It fits with RIBA stages, integrates into existing construction processes, and does not require a specific building procurement model.  You can download Soft Landings guidance from the BSRIA website .

However it is always helpful to find out about real world experiences, and to talk to others who are using Soft Landings to help them to produce better buildings.  With this in mind, BSRIA have organised the 2017 Soft Landings Conference (June 16th 2017 at RIBA, Portland Place, London W1B 1AD). You will hear from a range of speakers from different parts of the construction process – including clients – who will explain how they have used Soft Landings in their projects, and the value that it has delivered for their buildings.  You will also hear their hints and tips, and there will be plenty of time to ask questions and take part in discussion both in conference and over lunch.

It’s time for the construction industry to catch up with other industries in terms of quality, to produce buildings that perform as expected, through a delivery process that gets it right first time.  Soft Landings is a process that helps the delivery chain to do this.  For more information on the conference please contact our Events Manager, Tracey Tilbry.

 

Contractors can’t build well without clients that lead

Did anyone see the recent news story on the Edinburgh PFI schools with structural failures? In 2016 we shouldn’t be constructing buildings with feeble brickwork. We have Victorian and Edwardian schools that have been standing for over 100 years without these problems. More ironically we have 1960s CLASP schools – built on a budget with the flimsiest of constructions – still standing and performing their role well after their sell-by date. OK, they’re usually freezing in winter and boiling in summer, with asbestos in places a power drill shouldn’t reach, but at least they’re still standing.

The reasons for these high profile failures are easy to park at the door of the PFI process. One can blame cost-cutting, absence of site inspections, and lack of quality control. Some even say that the ceding of Building Control checks to the design and build contractor is a root cause: site labour can’t be trusted to mark their own exam paper when their primary interest is to finish on time and under budget.

Some commentators blame the design process, and bemoan the loss of days of the Building Schools for the Future programme when design quality was overseen by the Commission for Architecture in the Built Environment (CABE). The erstwhile CABE may have tried to be a force for good, but project lead times become ridiculously long and expensive. And would it have prevented structural failures? Hardly likely.

The one cause of these failures that doesn’t get enough press coverage is the important client leadership and quality championing. It can be argued that clients get what clients are willing to pay for, and there’s no industry like the construction industry for delivering something on the cheap. The cost-cutting, the emphasis on time and cost at the expense of quality control – all this can be pinned on a client base that does not lead, demand, oversee, and articulate what it wants well enough to prevent the desired product being delivered at the wrong level of quality at the wrong price.

Which means that clients have to a) get wiser on what can go wrong, b) get smarter with their project management, and c) articulate what they want in terms of performance outcomes. Truly professional designers recognise this, and are prepared to guide their clients through the shark-infested waters of writing their employers requirements. But once that is done the client’s job is not over. They can’t simply hand the job over to the main contractor and turn their back until the job is complete. They need to be closely involved every step of the way – and keep key parties involved beyond practical completion and into the all-importance aftercare phase.

Soft Landings provides a chassis on which focus on performance outcomes can be built. The chassis provides the client with a driving seat to ensure that standards are maintained, along with a shared construction team responsibility to make sure the building is fit for purpose.  The forthcoming BSRIA conference Soft Landings in London on 23 June is a good opportunity to learn how this can be done. It will focus on workshops where problems can be aired and solutions worked through. It will be led by experts in the field who can suggest practical solutions for real-world projects.

Ideas competition – How would you make buildings better?

PrintBSRIA and Designing Buildings Wiki are giving you the chance to win £500 of BSRIA membership, training or publications and to be featured in Delta T magazine by suggesting ways that buildings can be made to perform better. Gregor Harvie, co-founder of Designing Buildings Wiki explains why.

The UK government’s commitment to progressively reduce carbon emissions compared to 1990 levels is broadly in line with the COP21 goal agreed in Paris last year for keeping global warming well below 2 degrees centigrade.

But the Climate Change Committee has reported we are not on track to meet the fourth carbon budget, which covers the period 2023-27, and that meeting the 2050 target, a reduction of more than two thirds compared to today’s levels, will “…require existing progress to be supplemented by more challenging measures.”

construction emissions The construction industry generates or influences 47% of UK carbon emissions, and 80% of those emissions are from buildings in use. So unless the performance of buildings is improved, we will struggle to meet our carbon reduction commitments or the COP21 goal.

The tightening of the building regulations is intended to help deal with this. But figures from Innovate UK’s Building Performance Evaluation Programme have revealed that the carbon emissions of the 76 homes assessed were 2.6 times higher than their building regulations calculations, and emissions of the non-domestic buildings were 3.8 times higher.

And of course the building regulations do little to improve the existing building stock. Its estimated that around two thirds of the housing that will be occupied in 2050 has already been built.

emissions target v actualIn fact, our actual energy consumption has changed relatively little since the 1970’s, and the reduction in carbon emissions achieved to date has largely been the result of a shift away from coal powered generation. Now that the low hanging fruit have been taken, the task gets harder.

Couple this with a population expected to rise from 65 million now to around 77 million by 2050, and we have a problem.

So what can be done?

BSRIA and Designing Buildings Wiki have launched an ideas competition asking ‘how would you make buildings better’.

The challenge requires outside the box thinking to come up with radical ideas for reducing the emissions of buildings in use. Tell us about those innovations you think of in the middle of the night and the solutions to the world’s problems you only come up with after a few hours in the pub. Whether you think the answer lies in the adoption of smart technology, better regulation, on-site generation, monitoring and feedback, or more drastic measures such as carbon rationing or a contractual requirement for buildings to achieve design standards. The more innovative and far-reaching the idea the better.

The competition is very simple to enter. You don’t need to write a long essay, your idea might only take a paragraph, or even a sentence to explain.

To enter, go to the ‘Make buildings better’ page on Designing Buildings Wiki 

The winner will receive £500 worth of BSRIA membership, training or publications, and along with 4 runners-up, will be featured in the July edition of BSRIA’s Delta T magazine and on Designing Buildings Wiki.

The competition closes on Wednesday 18 May.

Architect Dr Gregor Harvie is co-founder of Designing Buildings Wiki, a free, cross-discipline knowledge base for the construction industry written by its users. It is home to more than 3,200 articles and is used by more than 10,000 people a day. Designing Buildings Wiki is supported by BSRIA, CIOB ICE, BRE, RSH+P, Buro Happold and U+I Group.

Just when you thought it was safe to relax about Energy

This blog was written by BSRIA's Henry Lawson

This blog was written by BSRIA’s Henry Lawson

Did you hear about the crisis that hit the UK on 4th  November, causing  massive disruption, and provoking outcry in industry, and suddenly sent energy rocketing back up the UK’s political agenda?

You probably didn’t hear this, because the first major threat to the UK’s national grid this winter still left it with a princely 2% spare capacity, sufficient for the National Grid to issue a “notification of inadequate system margin” (NISM), but insufficient to actually disrupt the service.

While this was only the first stage of alert, and while an abnormal lack of wind was an aggravating factor – bringing the UK’s now significant wind generation capacity almost to a halt, one of the mildest starts to November on record may have helped to save the day. As so often in human affairs, a “near miss” is treated as a near non-event. A single “hit” on the other hand could have major repercussions, prompting much more urgent action not just on the resilience of the UK’s national grid, but on how buildings respond to peaks and troughs in energy demand.

BSRIA has been reporting and analysing on Building Energy Management and the issues around it for a number of years now. One of the trends that we have noticed is that over time, more suppliers of building energy management solutions include some form of Demand Response as part of their solution. This enables a temporary reduction in the power drawn by certain services in the building where this does not impact on productivity or well-being.

Our latest review of the global leaders in Building Energy Management showed that almost half now offer demand response, the highest figure that we have seen to date. This includes both the global leaders in Building Automation and Energy Management and suppliers specialising in energy management.

At the same time, energy storage is being taken more serious as a viable and cost-effective way of providing additional resilience and peak capacity, both for energy suppliers and in some cases for consumers. While the UK is still some way from having a thriving market in home energy storage systems comparable to that developing in Germany (where residential electricity is significantly more expensive), it seems quite likely that any significant grid outages will give a boost to the market for battery storage for both residential and non-residential use.

It is still quite hard to judge how probable a major power outage is in the UK this winter. There are already further processes for demand reduction which can be invoked if the situation gets tighter than it did on November 4th. However a coincidence of severe cold with a lack of wind, and unplanned outages at power stations is not inconceivable. And the major strategic initiatives, such as the construction of two new nuclear power plants, will take years to come online.

The UK has got used to ‘living dangerously, and so far has got away with it. But the sensible response to a lucky escape is to learn the lessons, and  not to assume that your luck will go on holding indefinitely.

The very least we can say is that all organisations should be looking at the potential implications of even a short interruption to power supplies, and how they can best mitigate these.

I shall be talking a bit more about BSRIA’s latest research into building energy management and related areas in a webinar on Tuesday 24th November, so I hope that you will be able to join me then

A loveliness of ladybirds

This blog was written by BSRIA Graduate Engineer Joe Mazzon

This blog was written by BSRIA Graduate Engineer Joe Mazzon

Do you know the collective noun for a group of ladybirds?

It’s a loveliness, cute isn’t it! Why do I know this?

My MSc dissertation was entitled The Mechanics of Insect Adhesion, I worked with both Asian Weaver Ants and an assortment of British ladybirds, I looked after a batch of each, a colony of Ants and a loveliness of ladybirds.

I was researching the strong adhesive forces associated with insect species, Ants are seen every day carrying objects such as leaves and twigs that are many times their own bodyweight, the very nature of the tiny beings lends them enough equivalent muscular strength per unit size to perform amazing feats of strength. But carrying these masses up vertical walls and across the underside of horizontal surfaces opens up a whole new world of incredible biological engineering

There is a famous picture of an Asian Weaver Ant suspended from a glass ceiling holding a 500mg weight between its jaws. This creature is supporting 100 times its own body weight upside down from a very smooth glass surface, the forces on its tiny feet are incredible and it was my job to look into them

I wanted to find out just how much force the ants could withstand, basing my research on previous studies from Cambridge I constructed an extremely efficient centrifuge to which I could attach discs of various materials and spin them to high rotational velocities.

I used an upside down pillar drill and a plastic box.

No really, my extremely advanced scientific equipment came from the scrap pile of the university workshop, now that’s a testament to frugal engineering.

I would take a specimen, place him on the disc and turn the drill on, slowly at first, steadily increasing the speed of rotation until the ant would detach and fly onto the protective outer casing. The whole process was videoed from above using a high speed webcam. The result, after carefully rescuing the little guy and putting him back into his enclosure, was a video of a black blur that formed a circle, I could measure the diameter of the circle at the moment of detachment (when the black blur disappeared) match that distance to the angular velocity and calculate a force of detachment.

The same process was used for the ladybirds although the blur generally had a slightly red tinge and the noise of a ladybird hitting a Perspex wall at high velocity was surprisingly louder than you may think.

I should make the important point that none of the insects were actually harmed in the making of this dissertation, part of my job was to care for the health of my specimens. I had a small loveliness that needed to be kept in good health for testing, I read as much biology as I did physics for the project, I even learnt how to sex ladybirds which is incredibly hard to an untrained eye.

Our results successfully agreed with the literature, our ants were holding on to the glass substrate at 100 times the force of their own body weight.

In an attempt to understand the physical mechanism of the adhesion we tested different glass coverings, some hydrophobic and some hydrophilic, the suggestion was that some insects would secrete a liquid to maximise the surface area of their feet in contact with the substrate, we postulated that a hydrophobic surface, one that water doesn’t stick to, would show a decrease in the adhesive potential of the animal, our results couldn’t prove such a fact but they did strongly suggest it.

Most people I share this story with assume that ants feet are the same as Gecko feet in that they adhere using tiny hairs that maximise surface area in contact with the surface, this is not true. Ants utilise small hairs on some aspects of their feet but not for adhesion, instead they have a thin fleshy pad that unfolds from between two, toe like claws that then molds itself to the surface. This pad, called the Ariola, is what makes the ants stick to surfaces.

As a relatively new graduate engineer at BSRIA I am still attempting to find an application of this knowledge to the building service industry, I’m not sure that I will achieve this goal but I will keep looking.

So there we go, a loveliness of ladybirds, how’s that for a nice thought for the day.

University of Reading Research Study: Indoor Environmental Quality and occupant well-being

Gary Middlehurst is a post-graduate student at the University of Reading's School of Construction Management and the Technologies for Sustainable Built Environments

Gary Middlehurst is an Engineering Doctorate (EngD) student at the University of Reading’s School of Construction Management and the Technologies for Sustainable Built Environments (TSBE)

Looking at a new approach for determining indoor environmental quality (IEQ) factors and their effects upon building occupants, BSRIA has provided the University of Reading’s School of Construction Management and the Technologies for Sustainable Built Environments (TSBE) Centre access to their Bracknell office building known as the “blue building”.

 IEQ factors are proven to affect occupant well-being and business performance, however, for the first time, actual environmental and physiological field measurements will be compared. New research therefore has been developed by the University of Reading, which will seek to understand these relationships and the potential impacts of known IEQ factors on perceived levels of occupant satisfaction and well-being.

Understanding fundamentally how IEQ factors can affect building users, will allow system designers to finally visualise occupant well-being, personal satisfaction and productivity as part of a holistic business performance model. Based upon empirical measured IEQ factors and surveyed occupant data, the research hypothesis proposes that high-density occupation can reduce office workplace environmental footprints significantly when physiological impacts are understood.

The research methodology brings together measured environmental characteristics, physiological performance measurements, POE survey responses, and then uses an Analytic Hierarchy Process (AHP) to assess existing workplace designs.

Gary Middlehurst blogReducing operational costs and increasing occupant satisfaction and well-being is seen as a distinct competitive advantage, however, businesses remain focused towards meeting the challenges of energy security, demand side management and carbon commitments. The research, therefore, will provide empirical data to create informed business decisions focused upon these challenges. This is done by increasing the importance of well-being and by defining performance as a key metric.

Field research is currently underway on the top floor within the “blue building”, where 4 willing volunteers are participating in physiological sensory measurements and POE response surveys. The project will be running for 12-months, with the initial current 2-week data acquisition period being repeated a further 3 times during winter, spring and summer of 2015/16.

The research is also being conducted at two other similar office environments in Manchester and London, and seeks to support the hypothesis that hi-density workplaces are a further sustainable step in designing and operating more efficient and effective intelligent buildings.

The Building Services/Engineering ‘BIM Readiness’ Survey

BECA_strapSRIA is delighted to be supporting a sector-wide BIM survey which has been launched by the Electrical Contractors’ Association (ECA), alongside the Chartered Institution of Building Services Engineers (CIBSE) and Building, the UK’s leading magazine for construction professionals.

The new study will explore the readiness of the building services sector to engage with BIM within the next six to 12 months. The survey is also supported by other leading players in the sector, including the British Electrotechnical and Allied Manufacturers’ Association (BEAMA).

The investigation is expected to reveal crucial information about how prepared the sector is to adopt ‘BIM Level 2’ practice, noting the government requirement for BIM Level 2 engagement with centrally procured contracts during 2016.

BSRIA’s Principal Consultant and BIM specialist, John Sands, commented:

“With the implementation of the UK Government’s Level 2 BIM mandate just a few months away, the building services industry should be in a position to make the most of the opportunities it will present. This survey will help us all to identify where we are in the BIM journey, and to enable us to plan the way forward to BIM maturity.”

ECA Director of Business Services, Paul Reeve, said:

“This sector-wide survey will provide much needed and very timely information on how ready the building services sector is to engage with BIM as we approach the 2016 government deadline.

We urge all building services companies to take part in the new survey, and we will be sharing the data with the industry, the Government and other stakeholders when the results are in during September 2015.”

CIBSE Technical Director, Hywel Davies, added:

“Government is committed to using BIM to improve its management and operation of buildings and infrastructure. Mechanical, electrical and plumbing services are all critical to the effective operation of buildings. Our sector is involved in the operational life and performance of built assets, not just the design and delivery. This survey is important for our sector to understand how well prepared we are for BIM.”

The BIM study will run until September 15. 

Notes to readers:

More information about BIM (Building Information Modelling)

• ‘Level 2 BIM’ is the process of working with digital building information, including data-rich objects, which can be effectively shared between those who are building and/or maintaining the building and its services. This is ‘collaborative 3D BIM’ and it involves using tools such as COBie, BS/PAS 1192, ‘Soft Landings’ and various BIM Protocols.

• The Government aims to require collaborative 3D BIM on its centrally procured projects by spring 2016 (BIM Level 2), in order to unlock innovation and benefits throughout the building project life-cycle, including cost savings.

About the Electrical Contractors’ Association (ECA):

The Electrical Contractors’ Association (ECA) is the UK’s largest trade association representing electrical, electrotechnical and other engineering contractors, at regional, national and European level. ECA member-companies are rigorously assessed before membership is approved.
