How building 'green walls' can cut indoor pollution and promote more productive offices

Cities across the globe have long harnessed the power of nature by integrating more green spaces in urban development plans to boost the environment, as well as improve well-being.

But research in the UAE has underlined how creating additional green spaces should not be merely confined to streets and parks, but can be crucial to cultivating healthier, happier and more productive workplaces, too.

A study by Atina Ghunaim, a postgraduate researcher at UAE University (UAEU) in Al Ain, has highlighted how living or green walls - structures covered with greenery and vegetation - can cut down on pollution and create cleaner air in premises where employees can typically spend 2,000 hours a year.

Ms Ghunaim analysed pollution in the UAEU’s offices during the autumn and winter, and found that concentrations of particulate matter fell when there was a living wall installed. Levels of volatile organic compounds (VOCs), some of which have been linked to increased cancer rates, were also lower.

Cleaning the air inside homes, workplaces and other locations could offer significant health benefits, as the World Health Organisation has estimated that globally each year 4.3 million people die prematurely because of polluted indoor air.

Going green

Green walls may provide monetary and environmental upsides, because the UAEU research found that when such a wall was installed, the internal temperature was reduced by between 0.3 °C and 1.0 °C, which could cut energy demand for cooling.

According to analysis by Indian-based company, Straits Research, the global market for green walls is set to double in size in the decade up to 2031, when it is projected to be worth $5.3 billion (Dh19.5 billion).

Hisham Elkadi, a professor of architecture at the University of Salford in the UK who has researched living walls, said that the way that they brought nature into the urban environment “absolutely” offered benefits.

“The more we’re integrated with nature the better for us, for our environment, for health. There’s no question this is the way forward,” he said.

Internal and external benefits

As well as internal green walls improving internal air quality, external green walls clean the air outside, Prof Elkadi said, by removing particulate matter, harmful gases and VOCs.

There are also thermal benefits to external green walls: they reduce the heating effect on buildings in hot climates and limit the loss of heat from buildings in cooler parts of the world. Research in the UK published in 2021 found that heat loss was cut by 31 per cent when a pre-1970s building was retrofitted with a living wall.

“It’s mitigating the transmissions of energy from the atmosphere, and towards the atmosphere … The plants have very good control over the energy efficiency of buildings,” Prof Elkadi said.

Living walls and other plant life in towns and cities, including trees, also mitigate the urban heat island effect, which causes built-up areas to become hotter than surrounding areas. People who can see green walls while they are working have also been shown to have increased productivity, Prof Elkadi said.

By helping to increase the number of insects and birds, green walls can improve biodiversity, which Prof Elkadi said could contribute to urban areas becoming “green corridors” for nature instead of barriers to them.

However, green walls in hotter climates are at a greater risk of drying out, which can turn them into a fire hazard, so correct installation and regular maintenance are important.

How are companies tackling air pollution?

Many companies now provide green wall installations, both internally and externally, while green roofs are similarly becoming more popular and can, Prof Elkadi said, also reduce the urban heat island effect.

Employers around the world are making efforts to reduce internal air pollution. In India, for example, Acer has reportedly installed air purifiers in its offices, as have PepsiCo, Deloitte and KPMG, all of which have additionally brought in extra greenery to filter the air.

Simple pot plants have also been shown to reduce internal air pollution, according to research by the Royal Horticultural Society and the University of Birmingham, both in the UK.

Meanwhile, Royal Grammar School Guildford Dubai opened in 2021 with a sustainable vision supported by living walls and palm trees in the central atrium to encourage air circulation.

Another approach to clean the air, by deploying a spray-on coating for walls and other surfaces, is being offered by UAE company, Best Pick Energy.

The firm and its UK partner, Clean Air, which promotes the technology developed in Hungary by Resysten, said the method had been demonstrated to remove nitrogen oxides (NOX) from the air.

“Around the world you have zones and areas where you have naturally high concentrations of NOX sitting in the atmosphere. That tends to be in cities, it tends to be around transport hubs, it tends to be around construction sites,” said Steve Lewis, chief executive of Clean Air.

He said that the coating, which contains titanium dioxide, had been sprayed on to, for example, glass facades, vehicles, lorries and perimeter fencing around construction sites.

Construction sites are known as pollution hotspots and, with air pollution from traffic having fallen in some countries because of tighter emissions regulations, the share of air pollution accounted for by construction has increased.

Mr Lewis said a major global operator of drive-through fast-food outlets had contacted the firm about the possible use of the technology, which could reduce the extent to which employees are exposed to pollution.

The company states that the spray can remove 222mg of nitrogen dioxide per square metre per day, which can lead to a significant total across a large project.

Trials are taking place in the UAE to further test the technology with a view to rolling it out in the country, with the potential for it to be used both internally and externally.

So, from employing the age-old cleaning power of plants to using high-tech sprays, efforts to purify polluted air indoors and outdoors look set to grow.

Why does a queen bee feast only on royal jelly?

Some facts about bees:

The queen bee eats only royal jelly, an extraordinary food created by worker bees so she lives much longer

The life cycle of a worker bee is from 40-60 days

A queen bee lives for 3-5 years

This allows her to lay millions of eggs and allows the continuity of the bee colony

About 20,000 honey bees and one queen populate each hive

Honey is packed with vital vitamins, minerals, enzymes, water and anti-oxidants.

Apart from honey, five other products are royal jelly, the special food bees feed their queen 

Pollen is their protein source, a super food that is nutritious, rich in amino acids

Beewax is used to construct the combs. Due to its anti-fungal, anti-bacterial elements, it is used in skin treatments

Propolis, a resin-like material produced by bees is used to make hives. It has natural antibiotic qualities so works to sterilize hive,  protects from disease, keeps their home free from germs. Also used to treat sores, infection, warts

Bee venom is used by bees to protect themselves. Has anti-inflammatory properties, sometimes used to relieve conditions such as rheumatoid arthritis, nerve and muscle pain

Honey, royal jelly, pollen have health enhancing qualities

The other three products are used for therapeutic purposes

Is beekeeping dangerous?

As long as you deal with bees gently, you will be safe, says Mohammed Al Najeh, who has worked with bees since he was a boy.

“The biggest mistake people make is they panic when they see a bee. They are small but smart creatures. If you move your hand quickly to hit the bees, this is an aggressive action and bees will defend themselves. They can sense the adrenalin in our body. But if we are calm, they are move away.”

How will Gen Alpha invest?

Mark Chahwan, co-founder and chief executive of robo-advisory firm Sarwa, forecasts that Generation Alpha (born between 2010 and 2024) will start investing in their teenage years and therefore benefit from compound interest.

“Technology and education should be the main drivers to make this happen, whether it’s investing in a few clicks or their schools/parents stepping up their personal finance education skills,” he adds.

Mr Chahwan says younger generations have a higher capacity to take on risk, but for some their appetite can be more cautious because they are investing for the first time. “Schools still do not teach personal finance and stock market investing, so a lot of the learning journey can feel daunting and intimidating,” he says.

He advises millennials to not always start with an aggressive portfolio even if they can afford to take risks. “We always advise to work your way up to your risk capacity, that way you experience volatility and get used to it. Given the higher risk capacity for the younger generations, stocks are a favourite,” says Mr Chahwan.

Highlighting the role technology has played in encouraging millennials and Gen Z to invest, he says: “They were often excluded, but with lower account minimums ... a customer with $1,000 [Dh3,672] in their account has their money working for them just as hard as the portfolio of a high get-worth individual.”

Islamophobia definition

A widely accepted definition was made by the All Party Parliamentary Group on British Muslims in 2019: “Islamophobia is rooted in racism and is a type of racism that targets expressions of Muslimness or perceived Muslimness.” It further defines it as “inciting hatred or violence against Muslims”.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.

Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.

Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.

Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.

“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.

Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.

From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.

Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.

BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.

Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.

Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.

“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.

Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.

“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.

“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”

The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”
