Cooling down: The architects aiming to make outdoor life in UAE more comfortable

Changes in architecture could allow UAE residents to spend up to eight months of the year feeling comfortable while outside, an expert said.

Kishore Varanasi, director of urban design at US-based CBT Architects, says elements such as green walls, channels that create breezes and shading will help to reduce heating effects.

Mr Varanasi, who has completed work in Masdar City and whose designs have won awards in the Abu Dhabi Climate Resilience Initiative, said planners should focus on making the coolest two thirds of the year as pleasant as possible for residents.

While in the hottest months being outside for long periods is difficult regardless of the design of outdoor spaces, he said work to reduce heating could extend the period people spend outdoors by a month or two each year.

"It's really unbearable for three or four months," he said of UAE temperatures. "For six months, it's not that bad. And there are a couple of shorter months [that could be made comfortable].

While periods such as late September and early October, and late April and early May, might be considered too hot and humid, Mr Varanasi believes these "shoulder" periods can be made more comfortable.

“Should we take a different approach and focus on the eight months – late September, October to March, April, early May? If we reset the design methodology we can increase the outdoor months. That was one thing we’ve focused on – thinking about the time of use,” he said.

Mr Varanasi used this design approach when creating several outdoor spaces for the Abu Dhabi Climate Resilience Initiative several years ago.

He describes the use of shading as “low-hanging fruit” but said there are approaches other than simply installing sunshade, which can sometimes result in heat being trapped. “We realised that was only protecting in the middle of the day, when the sun is pretty much on your head,” he said.

“[People] are likely to be out before work and again in the evening, when the sun angle is much lower. We felt we needed to recalibrate the design during the day. The sun moves around. We’re beginning to think about the time and the angle of shading. We came up with more vertical shading rather than horizontal.”

In the shade

Mr Varanasi said it any shade should ideally be mobile so it does not have to be in place for 24 hours a day.

“A shade that sits on a space has a danger of trapping heat over time,” he said. “One of the things we’ve done with the shade was, in the case of plazas, to have the shade disappear at night, to expose the night sky.”

CBT Architects, based in Boston, Massachusetts, has for more than a decade carried out planning and design work for Masdar City and in places such as Al Hudayriyat Island, where sports, leisure and residential projects are being developed. The company has also undertaken work for the Department of Municipalities and Transport in Abu Dhabi.

One of CBT Architects’ flagship schemes in the country involves the Abu Dhabi Climate Resilience Initiative, for which the firm created a mosque plaza, an intersection and a small park.

These projects, which have all been completed, offer what the company has previously described as “a new paradigm for public space design for all places that face urban heat issues”.

Aiming to create “cool spots, paths, walls and canopies”, they could make users comfortable even during warmer months – albeit not at the height of summer – and at “shoulder” periods of the day outside of the hottest hours. The schemes made the finals of the World Architecture News Awards in 2022.

CBT Architects has also been involved with in an urban forestry project in Riyadh. As well as having shade to limit solar radiation, Mr Varanasi said that outdoor spaces should be designed to maximise airflow.

Wind of change

Mr Varanasi, a senior principal at CBT Architects, has taken inspiration from the traditional Arabian Sikka – narrow alleyways between structures.

“They’re close to buildings that provide shade but channel the winds,” said Mr Varanasi, who was born and raised in India before he moved to the US.

He also said low walls could reduce the heating effect from nearby roads. "Green walls", planted with vegetation, can also be effective at reducing heating.

To minimise outdoor heating, Mr Varanasi suggests a four-pronged approach. This consists of vertical shading, green walls (which also channel air), native vegetation and reflective materials. “If you’re using just one [of these measures], you’re not going to get the comfort that you need,” he said.

Native vegetation can create microclimates cooler than surrounding areas, demonstrated by numerous academic studies. Their shading effect reduces temperatures, while the process of evapotranspiration, in which plants release water vapour, consumes energy and lowers temperatures.

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.”

The design

The protective shell is covered in solar panels to make use of light and produce energy. This will drastically reduce energy loss.

More than 80 per cent of the energy consumed by the French pavilion will be produced by the sun.

The architecture will control light sources to provide a highly insulated and airtight building.

The forecourt is protected from the sun and the plants will refresh the inner spaces.

A micro water treatment plant will recycle used water to supply the irrigation for the plants and to flush the toilets. This will reduce the pavilion’s need for fresh water by 30 per cent.

Energy-saving equipment will be used for all lighting and projections.

Beyond its use for the expo, the pavilion will be easy to dismantle and reuse the material.

Some elements of the metal frame can be prefabricated in a factory.

 From architects to sound technicians and construction companies, a group of experts from 10 companies have created the pavilion.

Work will begin in May; the first stone will be laid in Dubai in the second quarter of 2019. 

Construction of the pavilion will take 17 months from May 2019 to September 2020.

What it means to be a conservationist

Who is Enric Sala?

Enric Sala is an expert on marine conservation and is currently the National Geographic Society's Explorer-in-Residence. His love of the sea started with his childhood in Spain, inspired by the example of the legendary diver Jacques Cousteau. He has been a university professor of Oceanography in the US, as well as working at the Spanish National Council for Scientific Research and is a member of the World Economic Forum’s Global Future Council on Biodiversity and the Bio-Economy. He has dedicated his life to protecting life in the oceans. Enric describes himself as a flexitarian who only eats meat occasionally.

What is biodiversity?

According to the United Nations Environment Programme, all life on earth – including in its forests and oceans – forms a “rich tapestry of interconnecting and interdependent forces”. Biodiversity on earth today is the product of four billion years of evolution and consists of many millions of distinct biological species. The term ‘biodiversity’ is relatively new, popularised since the 1980s and coinciding with an understanding of the growing threats to the natural world including habitat loss, pollution and climate change. The loss of biodiversity itself is dangerous because it contributes to clean, consistent water flows, food security, protection from floods and storms and a stable climate. The natural world can be an ally in combating global climate change but to do so it must be protected. Nations are working to achieve this, including setting targets to be reached by 2020 for the protection of the natural state of 17 per cent of the land and 10 per cent of the oceans. However, these are well short of what is needed, according to experts, with half the land needed to be in a natural state to help avert disaster.

Labour dispute

The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.
