Monitoring and maintaining swimming pool water quality

As we dive into Water Quality Month, what better topic to discuss than swimming pools?

Summer is starting to wind down, and many of us will be using these next few weeks to enjoy the comfort of our private swimming pools and spas.

Water Quality Month is here to remind us all that any pool or spa, big or small, should always be kept clean and regularly tested. Proper maintenance standards will ensure your pool remains clean, safe, and free of any potential maintenance hazards.

Water quality management is key

Swimming pool water management is often regarded as an art and science of its very own.

Achieving the perfect level of cleanliness while simultaneously balancing the right backwash and water replacement techniques has a steep learning curve, but will pay off in the end.

A consistent testing regime will provide any pool owner with the necessary data to make effective adjustments and ensure water quality meets the highest standards.

Test, test, test!

As any pool owner knows, active pool hygiene management helps prevent dirty buildups and kills hazardous bacteria. But regular testing can also help you optimise your pool cleaning techniques to ensure you’re engaging in the most cost-effective and safe pool management.

Regular monitoring can help address maintenance problems that may lead to bigger issues such as filter damage, failing systems, and chemical overdosing.

Some of the problems and concerns that a good water testing regime can address and improve include:

If your disinfection levels are up to scratch

Adequate dosing and balance of chemicals are critical for controlling bacterial growth and maintaining excellent water quality.

Whether or not backwashing and water replacement are being done correctly

The cost of water is on the rise, and you’ll want to know if you’re spacing out your water replacement at decent intervals. Efficient backwashing must be calibrated to keep your filtration system running properly.

If chemical dosing is well balanced

Improper chemical treatment can damage your pool equipment and be harmful to swimmers. Regular monitoring will ensure your pool and your guests remain safe.

Water treatment plant monitoring

Regular water testing will help assess the status of your water treatment plant and help catch any possible issues early on. Some plants may be under strain, and you’ll want to address any potential repairs before it’s too late.

Filter bed condition

You’ll want to monitor your pool’s filter bed and make the necessary replacements as often as necessary.

As we’ve previously discussed, pools can be a great luxury, but with great luxury also comes great responsibility. The consequences of poor pool maintenance can be dangerous and can lead to water-borne illnesses like E. coli and  Legionnaires’ disease.

Water quality and pool safety go hand-in-hand

The correct use of chemicals, a well-fitted filtration system, adequate circulation, and regular monitoring of pH levels are the best-combined methods for maintaining a safe and healthy swimming environment.

By engaging in these practices, we can guarantee our pools and spas will remain safe and enjoyable for all.

If you’re a pool or spa owner, you can always reference the Pool Water Treatment Advisory Group (PWTAG) code of practice to address any issues or concerns regarding water quality treatment methods.

DJHC celebrates Good Care Month!

At DJHC, we pride ourselves on the work we do and the people we serve. As MEP professionals, it’s not just about finishing a job. The impact we make on our customers is important, and meeting their needs is our priority.

Every July, we celebrate Good Care Month. Good Care Month celebrates the care workers and facilities who dedicate their services to improving the lives of those in need.

As with any specialised building, care homes are designed with specific needs in mind. For people living and working in care homes, comfort is particularly important. 

In the past few years, DJHC has had the privilege of working on projects related to the care sector, and we know first-hand how important MEP design is to these facilities.

MEP design and care facilities 

At DJHC, we understand that engineering is what makes a building come to life.

MEP design is fundamental to providing and maintaining base comfort levels inside a structure. From heating, cooling, ventilation, and lighting – buildings are only as comfortable as the way they’re designed. Without well-planned MEP elements, a building might as well just be a shell.

In celebrating Good Care Month and thinking about designing for comfort, we can reflect on some previous projects DJHC has completed for the care sector.

Haven House 

We recently worked on the Haven House project. Haven House is a residential facility that provides end-of-life care for children and young people living with chronic conditions.

As with many older structures, overheating and deficient ventilation were major problems for staff and residents at Haven House. During the summer months, common areas and bedrooms would often reach extreme temperatures that made living there uncomfortable.

Knowing that overheating was causing discomfort to staff and residents, we developed a custom-made, energy-efficient cooling system that provided adequate air conditioning throughout the building at low noise levels. 

In the end, this project was tailor-made to meet the needs of Haven House. 

Viera Gray House

In another project, we refurbished the ventilation and kitchen systems of the Viera Gray House, a care home specialising in residents who suffer from dementia.

Our initial brief mentioned that kitchen temperatures reached “uncomfortably hot” temperatures for staff because the room lacked a functional ventilation system.

DJHC was tasked with a full refurbishment of the kitchen to comply with today’s standards and provide adequate comfort levels for care workers.

In the end, we were successful in creating a suitable working environment by implementing the right MEP elements.

Spreading awareness about care workers

Care workers devote themselves to meeting the needs of our most vulnerable populations. Care home residents deserve to live in safe and comfortable environments.

At DJHC, we want to spread awareness about Good Care Month. July is an opportunity to remind everyone that care workers are important to our communities. They deserve our appreciation not just this month, but every day of the year.

Good MEP design isn’t just installing an air conditioner and going home at the end of the day. Every building has its own needs that need to be carefully considered when upgrading or refurbishing MEP elements. 

 

How sound (of all things) can make a building healthier

We’ve all had a night where we just can’t sleep. Right now it’s mostly down to the heat but often it’ll be noises that are keeping you up; it could be because of the neighbours, traffic, or a noisy fan on a hot night. Or, there might be some days where you just can’t focus in the office because of the low hum coming from the breakroom or street.

These phenomena aren’t just annoying, they can be damaging to your health, productivity, and mood. However, they’re not inevitable. In fact, building design can play a big part in controlling “noise pollution” with building acoustics. Let’s take a brief look at how this works.

Why are acoustics important in building design?

Noise pollution is harmful or annoying levels of noise. This may have a bigger impact on health than one may realise; certainly, being deprived of sleep is a serious problem. However, it can also impact our health more generally. Consistently being in an irritated state can lead to high blood pressure, coronary heart disease, and migraines.

It can also harm productivity. If we are constantly distracted, it naturally affects our output. According to a study from the American Society of Interior Designers (ASID), 70% of office workers reported that noise affects their productivity. With this in mind, optimising acoustics has the potential to create a lot of value for companies. But how do architects and engineers achieve this?

How do building acoustics work?

In buildings, there are two types of noise. This might sound like a strange concept, but it touches on how noise travels: it’s either airborne or structure-borne. Structure-borne noise is affected by the volume and geometry of a space. The position of the walls will impact the transmission and reflection of sound. Materials will also play an important part, as some absorb sound better than others, thus reducing noise.

Other design features will also play an important part in managing airborne noise. Some of the main culprits in most offices are:

  • Noisy HVAC systems.
  • Improper partitioning of areas.
  • Poor acoustic insulation.

However, there are steps that architects and engineers can take to control this noise. Even before a site is chosen, they can monitor environmental noise to assess whether or not a site is suitable for the project. Aeroplane noise, for example, could be a significant factor to consider.

For example, modelling and simulations can help to estimate a building’s acoustic function. Using insulating materials is another useful strategy, as well as testing and measuring sound levels on site. This enables architects to fine-tune the design at the construction phase.

Equipment selection will also play an important role. Often, budget options could produce unwanted noise; however, there are design steps that can be taken to reduce noise and vibrations from HVAC systems.

A healthier building in every sense

When we think of healthy building design, we often think of air qualitysustainability, and light. However, sound is an important factor that may be overlooked. As we’ve discussed, it can have a significant impact on the end user’s well-being, so should be carefully considered. Designing healthy buildings should consider all of the users’ needs and senses, and sound is more important than you may think.

 

 

Let’s breathe better this Clean Air Day 2022

The World Health Organisation has identified air pollution as the biggest environmental threat we face today. Every day, air pollution results in 36,000 deaths per year in the UK alone. These deaths would be preventable if we did more to care for the air we breathe. Clean Air Day, which is tomorrow, was conceived to raise awareness of this issue.

The theme of this year’s campaign is “air pollution dirties every organ in your body”. This was chosen to highlight how poor air quality affects organs beyond your lungs. When we breathe polluted air, it inflames the lining of the lungs. This allows harmful particles to enter the bloodstream and affect every organ.

Poor air quality can shorten lives and make us more susceptible to heart disease, lung disease, dementia and strokes. However, when most people think of air pollution, they think of outdoor air pollution, like smog and car emissions. In fact, some of the most harmful air is inside our homes and workplaces.

Where does indoor air pollution come from?

A study in the United States estimated that the average person spends about 90% of their time indoors. This is compared to an average of 40 hours a week of exposure to industrial pollutants. Therefore, the air we breathe indoors makes up the vast majority of our intake.

The main problem is, that in cold climates like the UK, doors and windows are often tightly closed. This allows pollutants to build up. These particles can cause respiratory disease and even certain types of cancer. But where are these particles coming from?

Many of them are biological pollutants like mildew, mould and pollen. Some of these particles can trigger allergies or cause serious illness. Black mould, for example, can cause headaches and fatigue. Equally, poor air quality allows viruses and bacteria to spread more easily. As we know all too well, the spread of COVID-19 has been linked to enclosed spaces.

However, poor indoor air quality can come from some sources that you may not expect. Varnishes and paints can emit dangerous volatile organic compounds (VOCs) long after they’re dry. Seemingly innocuous products like air fresheners and deodorisers also use volatile and semi-volatile ingredients that are largely unregulated. Copiers, laser printers and glues also give off VOCs that can penetrate lung tissue.

How can you reduce indoor air pollution?

One simple measure you can take to reduce indoor air pollution is to open a window. Often, even in the busiest areas, allowing some outdoor air to circulate will improve air quality not make it worse. However, in the dead of winter, this isn’t an attractive option. Air quality is important, but so is comfort.

A fail-safe strategy to improve indoor air quality is to install an air purifier. Air purifiers use filtration to remove harmful particles like mould, mildew, dust, and VOCs from the air. The most advanced models will also include a UVC light filter to virtually eliminate all pathogens. We recommend this system by Rejuvenair, which combines HEPA-13 filters with UVC to eliminate 99.9% of all pathogens.

Clean air is vital to the health of every organ in the body. This Clean Air Day, make a resolution to improve the quality of the air you breathe 90% of the time.

The science of smiling in our post-mask moment

Fingers crossed, the days of widespread mask usage are behind us. We can finally meet face-to-face in the most literal sense, with the full spectrum of our facial expressions visible once more. This is important to cultivating relationships; they say a picture is worth a thousand words and we’d argue a facial expression is the same.

But facial expressions aren’t just about how other people feel – it also affects how we feel ourselves. Considering today marks the beginning of National Smile Month, we wanted to use this article to talk about the science of smiles, now we can see them once more.

The ripple effect of smiling

It’s unsurprising that smiling and laughing are good for your mental health. After all, they’re the symptoms of happiness which are, in fact, hormonal. When you smile, your brain releases neurotransmitters like dopamine, serotonin and endorphins. The endorphins act as a mild painkiller and serotonin is an antidepressant. One study even suggests that smiling can reduce our heart rate and help us cope better with stress.

The effects of smiling aren’t limited to one individual. Many of us have observed the ripple effect of smiling or laughing, where a positive atmosphere can fill the room. In scientific terms, this is known as the “facial feedback hypothesis”, which states that facial expressions have the ability to modulate subjective experiences. Fascinatingly, this theory was proven by Swedish scientists in 2011.

Fake it ’til you make it

A recent study conducted at the University of South Australia found you don’t even need to be happy to reap the benefits of a smile. According to their research, when a person’s facial muscles are arranged in a smile, it can trick the brain into feeling good. This was tested by participants’ emotional responses when they were holding a pen in their teeth, mimicking the muscular form of a smile.

According to cognition expert Dr Fernando Marmolejo-Ramos, who worked on the study, “when you forcefully practise smiling, it stimulates the amygdala – the emotional centre of the brain – which releases neurotransmitters to encourage an emotionally positive state.” In conclusion, Dr Marmolejo-Ramos suggested that “a ‘fake it ’til you make it’ approach could have more credit than we expect.”

A new meaning for “grin and bear it”

Smiling isn’t only a symptom of happiness; it can also be a cause. These studies show that smiling helps us manage stress and get through day to day life; in fact, there could be more substance to the expression “grin and bear it” than we may think. These benefits don’t just apply to individuals – smiling can make others around you feel more positive too. 

So, now we’re transitioning into more positive times after the pandemic, we can tentatively take off the masks and crack a smile. Reading each other’s facial expressions is crucial to cultivating positive relationships, so it’s high time we embraced being truly face-to-face once more. Although there might still be challenging times to come, it’s scientifically proven what a positive outlook can do.

 

 

Maintaining ventilation systems to keep air quality high and costs down

This year, World Health Day on the 7th April coincides with Stress Awareness Month. Stress levels have a profound connection to our health, and in the wake of the pandemic, they’re running high. This is not least due to rising cases of COVID-19, but the rising cost of living in the UK, particularly energy bills. For homeowners and businesses alike, these huge price hikes are a serious cause for concern.

In regard to keeping our homes and workplaces comfortable and healthy, ventilation is a key aspect of HVAC. As the pandemic health advice has drummed into us, coronavirus spreads slower in well-ventilated spaces. The cheapest and most straightforward way to do this is to keep windows open. However, for many spaces, particularly those in businesses, this isn’t always possible, either for architectural or comfort reasons (particularly in an unpredictable British summer!).

Therefore, running efficient ventilation systems is essential to maintaining air quality and keeping costs down. In light of current events, an ignorance-is-bliss approach won’t cut the mustard, so here, we outline the basics to set you on the path to cleaner air for less.

Stay abreast of essential parts

Recently, we shared a piece on the summer essentials to keep your air conditioning running effectively. The same principles apply to any HVAC system, with the filter being of particular importance when it comes to maintaining air quality. However, these parts aren’t made to last. An old filter will seriously impact the efficiency of the unit, allowing dirt and debris into the airflow. Furthermore, blockages will increase the workload of the system, wasting energy.

Staying on top of the thermostat is also key. By monitoring the timer and temperature settings, you can reduce costs by only having the system on at peak times. This is because knowledge is power – and this is only the most basic strategy. We’ll move on to more sophisticated systems next.

Run a data-driven system

As we have asserted, knowledge is power, and that means data. The most sophisticated ventilation and air purification systems will incorporate intelligent sensors to measure air quality. This gives you a vital insight into how efficiently the system is working, enabling you to keep air quality as high as possible. Moreover, it’ll ensure the purifier, air conditioning unit or ventilation system is running at the optimum capacity.

Some models, such as these, also include smart maintenance updates. This will enable you to stay ahead of the parts and repairs mentioned in the previous section, combining these two essential pieces of wisdom. With automatic alerts to the supplier, maintaining the purifier will save you as much time as it will money.

Clean air is vital to our health. Maintaining a high-functioning ventilation and purification system needn’t cost the earth. Keeping costs under control is essential to managing stress as a business owner, and in turn, maintaining a healthier mindset. DJHC strongly recommends you invest in maintaining and improving your HVAC system in the workplace, to keep your team and the bottom line healthy. Click here to learn more.

 

 

Know the basics of keeping private pools clean and healthy

When thinking about starting a new construction project, water supply planning is an important, early-stage component that should never be ignored. Without a clean water supply, water can easily become a threat to our health. This supply is the lifeblood that allows us to safely cook food, drink water, wash and enjoy water for leisure, such as in swimming pools or Jacuzzis.

For the lucky few of us with the space and budget, what better way to enjoy a swim than in the privacy of your own home. Can you imagine that perfect slice of paradise in your own garden? Blissful. However, with great luxury comes great responsibility. The right design, contractor and maintenance are essential to ensure a safe, healthy space.

We recently talked about the threat of a common water-borne illness – Legionnaires’ disease. This illness attacks our lungs, and the bacteria that causes (legionella) can be found in most natural water sources such as rivers, reservoirs and lakes. More seriously, however, this hazardous bacterium can also make its way into facilities like swimming pools and spas.

The health, safety and maintenance of pools and spas

It’s usually commercial pools that have strict provisions for the prevention of Legionnaires’, but these shouldn’t be ignored in domestic spaces. So what measures are taken to ensure we’re safe in private pools?  How can we guarantee we aren’t at risk of contracting water-borne illnesses like Legionnaires’?

With summer just around the corner, private swimming pools will be coming into their own. These key factors should be considered when thinking about how water is cleaned:

  1. Water treatment, water recirculation and water replacement.
  2. Water quality monitoring and record keeping.
  3. General facility maintenance and hygiene.
  4. Bather hygiene and usage patterns.

The risk of bacterial contamination is low when best practices are applied. The safe use of chlorine, the regular monitoring of pH levels, properly fitted water filtration systems and the recirculation of water are the best practices for maintaining a safe environment for us to enjoy. By advocating for these simple practices, we can ensure the pools and spas we visit will remain safe and enjoyable.

An oasis of your very own

There’s no doubt these commodities are some of the most exciting additions to any home or property, raising the value by a substantial amount. Water is a basic, fundamental aspect of any building – but it can be a fun addition or a luxurious touch, providing the design and construction are up to scratch.

For pool and spa building, consultancy will be incredibly useful should you decide to break ground. Our experts at DJHC can advise you on the local water supply, the laws and regulations, the construction requirements, project management and the health and safety measures needed for you to enjoy your new oasis. Contact us here.

 

 

The summer essentials for your HVAC system

If you hadn’t already noticed (and we hope you have…or you will have been late to everything!) British Summer Time began on the 27th of this month.  This means warmer days, lighter nights, and some extra planning for staying cool over the summer season. Although turning our clocks ahead by one hour may seem like an unassuming seasonal ritual, it can have some real effects on the way we control the temperature.

When it comes to keeping your building comfortable this summer, maintenance is essential. Heatwaves mean air conditioners are going to be working overtime in the coming months and it’s important our HVAC systems work safely, not just in the cooling and heating sense, but also from a health perspective.

Filters don’t last forever

Air conditioner filters aren’t made to last. Unfortunately, remembering to check and replace them it’s something that often slips by the wayside in busy working environments, which can lead to serious problems down the road. Over time, the dirt and debris caught by filters will start to obstruct airflow.

Not only does this increase the workload of the cooling system, but it can lead to health problems because pollutants and dust particles have the potential to find their way into the building’s atmosphere. Also, as these filters deteriorate, they release debris directly into the mechanical components of the air conditioning system, which can lead to mechanical breakdowns.

By replacing the filters often, you can significantly reduce the wear and tear on your HVAC system and avoid costly and untimely repairs. The last thing we want is our air conditioner breaking down in the middle of a summer heatwave.

Thermostat monitoring to improve comfort levels

Another recommendation for the summer season is to closely monitor the thermostat. By automating and moderating the timer and temperature settings of the air conditioner, you can reduce energy costs and put less stress on your unit by running it only when needed, at peak hours.

Something else that’s recommended to stay cool is to keep your windows closed. As we discussed in our article on the importance of ventilation, outside air can have a major impact on a building’s temperature and moisture levels. A strategic combination of properly sealed windows alongside portable fans placed around the house can effectively ventilate a space and provide some of the most comfortable cooling solutions around.

Enjoy the summer days to come

Even if you’re just making minor adjustments to stay cool this summer, the clocks going forward is always an excellent time of the year to schedule a professional inspection of your HVAC system. This is especially true for older buildings that might not be up to the job, wasting precious energy and indeed, cash.

Depending on the set-up, a standard service will cover tasks such as flushing the condensate drain system, cleaning and lubricating the blower assembly, cleaning the evaporator and condenser coils and assessing the refrigerant levels. Proper maintenance of your system can always be guaranteed with the help of a trusted MEP engineer. Find out more here.

 

 

How can we preserve “water cooler moments” when face-to-face isn’t possible?

Most restrictions have now been lifted in the UK but many companies are still choosing to hold onto flexible or working from home options.  There are a variety of reasons why. Some businesses have found that it’s more efficient for them to run without the need for property to pay rent or rising energy bills. Across the country there is still an air of uncertainty with regards to virus transmission and many employees have now become so used to working from home that the thought of going back into the office can cause health problems.

That being said, some of the world’s biggest businesses, including banks stated that they want their employees back in the office back in February. Goldman Sachs, for example announced that they want to put an end to all remote work, while JPMorgan has also expressed their desire to get people back at their desks.

Jamie Dimon, the chief executive officer of JPMorgan, said that working from home “does not work for younger people, it doesn’t work for those who want to hustle, [and] it doesn’t work in terms of spontaneous idea generation.” These spontaneous ideas – sparked by conversations by the watercooler or in the breakroom – are the lifeblood of a dynamic company.

But over the past two years, hybrid or remote working has become a more common business model so what can we do to preserve these “watercooler moments” when face-to-face isn’t possible?

Is productivity really all that counts?

Although these chance encounters were certainly lost during the pandemic, remote working hasn’t caused a fall in productivity. Despite the anxieties of many bosses in the first round of lockdowns, many saw a rise in productivity. This is now well-reported; according to statistics published by Stanford University of 16,000 workers over 9 months found that working from home actually increased productivity by 13%.

But work isn’t just about productivity. Ultimately, we’re social animals and it can affect our performance and overall happiness in the long term. A study of UK workers by Indeed reported that 73% of employees miss socialising in person and 46% of respondents specifically said they missed the work-related side conversations that happen in the office. These unofficial encounters are fertile ground for ideas and knowledge sharing, so we need to think about how they can be maintained.

Going beyond the Zoom happy hour

Much like lockdown productivity stats, advice pieces about how to maintain a social workplace online are now all too common. However, many of us are now a little jaded by the suggestion of a Zoom happy hour – which often just ends in an awkward live stream of people sipping from beer bottles.

Thankfully, more well-thought-through ideas are starting to emerge. One school of thought is that these unstructured moments are, in fact, about structure. Chance encounters happen in the office when you’re getting set up, making an afternoon snack, or debriefing after a meeting. Therefore, being aware of everyone’s schedules is important to make time for each other.

The next step is actually nurturing relationships. Group calls can be clunky; there’s lag, people talking over each other, “you’re on mute” and so forth. Scheduling time to do one-on-one calls creates more meaningful, easier interactions. You can schedule these while doing the more menial tasks that are an inevitable part of the working day, like doing the washing up. If you struggle with conversation topics, activities like online gaming or a virtual book club are good ice breakers.

Despite the protests of some business leaders, it seems that remote working will be here to stay, at least for some businesses, whether compelled by the pandemic or not. It’s important to be creative and nurture these chance encounters to preserve the dynamism of workplaces and boost morale – or else we may see those productivity stats slip.

 

 

How light impacts productivity

Lighting is an important component of any space. It’s an integral part of a building user’s comfort, along with temperature, ventilation and layout, and certainly shouldn’t take a back seat. In fact, when it comes to productivity, it should be a major consideration; in fact, lighting can impact productivity just as much as an uncomfortable temperature or stuffy atmosphere.

According to a study conducted by the American Society of Interior Designers (ASID), an astonishing 68% of employees think the light in their workspace is inadequate. So what can designers and building managers do to improve these conditions? From good old fashioned fixes to new technologies, there are various solutions – it’s just a question of identifying your team’s most pressing need. Let’s look closer.

Control and colour

The survey conducted by ASID found a few key concerns; primarily, ample lighting is important. If daylight from windows isn’t available, then overhead lighting is essential, especially for task-based productivity. However, one intense light throughout the day isn’t the ideal scenario; in a perfect world, employees want to control. This could be individual desk lights or the installation of a smart lighting system to adjust with natural light levels.

Light intensity is only one consideration; another important factor is colour temperature. The crucial colour in the spectrum is daylight which, unsurprisingly, has an intimate relationship to wakefulness and productivity. Daylight is closer to the white end of the spectrum, as opposed to tungsten light, which is yellow. Employees are more energetic under white light, which is more akin to sunlight at high noon. Meanwhile, yellow light is more like the so-called “golden hour” when the sun sets, which can make people feel lethargic.

Of course, finding the right light temperature for the space will depend on how much natural sunlight is available and the unique features of the location. Achieving the right lighting in terms of colour temperature, coupled with giving employees more control over the lighting in general, can result in a boost in productivity and happier, more motivated workers.

A new hue in the mix

However, there is another colour temperature that’s playing a big role in our energy levels – blue light. Blue light is emitted by devices like computers, televisions, and phone screens, and has a unique effect on our moods and energy levels, both in the office and at home.

A National Sleep Foundation study showed that the glow from electronic devices suppresses melatonin and interferes with falling and staying asleep. A good night’s sleep is, of course, crucial to productivity, but as we all know too well, these devices are becoming increasingly central to our day-to-day working life – especially as remote working becomes the norm.

There are solutions emerging to manage the impact of blue light on our moods and motivation. Research conducted at the Indiana University Kelley School of Business collected data from a Brazil-based company to measure the impact of blue light filtration. Participants were randomly chosen to test glasses that filter blue light or placebo glasses.

According to the lead researcher, “We found that wearing blue-light-filtering glasses is an effective intervention to improve sleep”, which in turn, led to better “work engagement, task performance and organisational behaviour and reduced counterproductive work behaviour.”

Technological solutions for a fundamental issue

When it comes to optimising the light in your workspace, there is a range of solutions, from architectural strategies to individual tools. The question at hand for bosses is identifying the business’s most pressing need. For example, if your building is already flooded with natural light, perhaps access to blue light filtration is the boost your team needs. Or, if there are a limited amount of windows, it might be a question of getting back to basics with the right colour temperature.

Either way, light is key to employees’ comfort, which in turn, is essential to their performance. Light should be built into your plan for a comfortable workspace, so make sure it’s on the agenda, whether you’re embarking on a whole new build or just making some design tweaks to your office space.
