Inefficient air conditioners are a huge drain on electricity supplies - but now scientists in Abu Dhabi hope to make them less so.
Six new research projects at the Masdar Institute of Science and Technology are intended to find ways of making cooling equipment more efficient, and to measure the impact of energy efficiency measures.
Leading the research are Dr Afshin Afshari, professor of practice in engineering systems and management, and Dr Peter Armstrong, an associate professor of mechanical engineering.
Two of the projects will examine AC systems' chiller equipment and air-handling units, with the aim of developing GCC efficiency standards.
Cooling uses about 40 per cent of the UAE's electricity, said Dr Armstrong - but the area is often overlooked, and most commercial AC products are not optimised for the harsh climate. "The actual cooling equipment routinely used in the UAE is often selected more on first cost than on life cycle cost or performance," he said.
Maintenance is important, too, and so another project will look into "predictive maintenance" - monitoring equipment remotely and detecting problems before they cause huge disruptions. "There are huge maintenance issues with chiller equipment in Abu Dhabi," said Dr Afshari. "They are not maintained as they should be and one of the reasons for that is that people wait until the equipment fails ... before they go and do maintenance."
The scientists are also developing tools to gauge the effectiveness of energy efficiency measures.
Dr Armstrong is working on an electricity meter that can see not only how much energy is being used within a flat or office, but also what type of equipment is using it.
Such end-use metering is not new, but current devices use technology almost 30 years old. Dr Armstrong and his team hope to make an updated device. "If you know how much energy the building is using, you can break it down to kilowatt hours per square foot per year, perhaps, but you do not know what it is actually being used for," he said.
"Until you know what it has been used for, you really do not have much to go on as to what activities you should fund, and what technologies need to be improved."
The need to know more before deciding to act is also the rationale behind two assessment tools to be developed by Dr Afshari.
One model looks to assess the effectiveness of energy efficiency measures. That is not as easy as comparing a building's energy use before and after an intervention, as other factors - such as weather and occupancy rates - can affect the results.
An accurate and standardised assessment method would help Abu Dhabi develop a new industry around energy efficiency.
Dr Afshari is also working on a model that will let decision makers predict how much effect efficiency measures such as improving chiller efficiency and building insulation will have.
It combines hourly electricity consumption data with weather data to investigate the relationship between climate and cooling needs. It will allow for five or six parameters to be compared, calculating which approach will produce the largest results and how much it will cost to implement.
All six projects should be finished in two years. And ultimately, they should cut energy demand. "This means less power plants, less transmission assets and less distribution assets," said Dr Afshari.

Although social media can be harmful to our mental health, paradoxically, one of the antidotes comes with the many social-media accounts devoted to normalising mental-health struggles. With Hope UAE is one of them.
The group, which has about 3,600 followers, was started three years ago by five Emirati women to address the stigma surrounding the subject. Via Instagram, the group recently began featuring personal accounts by Emiratis. The posts are written under the hashtag #mymindmatters, along with a black-and-white photo of the subject holding the group’s signature red balloon.
“Depression is ugly,” says one of the users, Amani. “It paints everything around me and everything in me.”
Saaed, meanwhile, faces the daunting task of caring for four family members with psychological disorders. “I’ve had no support and no resources here to help me,” he says. “It has been, and still is, a one-man battle against the demons of fractured minds.”
In addition to With Hope UAE’s frank social-media presence, the group holds talks and workshops in Dubai. “Change takes time,” Reem Al Ali, vice chairman and a founding member of With Hope UAE, told The National earlier this year. “It won’t happen overnight, and it will take persistent and passionate people to bring about this change.”

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.

Ways to control drones
Countries have been coming up with ways to restrict and monitor the use of non-commercial drones to keep them from trespassing on controlled areas such as airports.
"Drones vary in size and some can be as big as a small city car - so imagine the impact of one hitting an airplane. It's a huge risk, especially when commercial airliners are not designed to make or take sudden evasive manoeuvres like drones can" says Saj Ahmed, chief analyst at London-based StrategicAero Research.
New measures have now been taken to monitor drone activity, Geo-fencing technology is one.
It's a method designed to prevent drones from drifting into banned areas. The technology uses GPS location signals to stop its machines flying close to airports and other restricted zones.
The European commission has recently announced a blueprint to make drone use in low-level airspace safe, secure and environmentally friendly. This process is called “U-Space” – it covers altitudes of up to 150 metres. It is also noteworthy that that UK Civil Aviation Authority recommends drones to be flown at no higher than 400ft. “U-Space” technology will be governed by a system similar to air traffic control management, which will be automated using tools like geo-fencing.
The UAE has drawn serious measures to ensure users register their devices under strict new laws. Authorities have urged that users must obtain approval in advance before flying the drones, non registered drone use in Dubai will result in a fine of up to twenty thousand dirhams under a new resolution approved by Sheikh Hamdan bin Mohammed, Crown Prince of Dubai.
Mr Ahmad suggest that "Hefty fines running into hundreds of thousands of dollars need to compensate for the cost of airport disruption and flight diversions to lengthy jail spells, confiscation of travel rights and use of drones for a lengthy period" must be enforced in order to reduce airport intrusion.

UAE currency: the story behind the money in your pockets
What the law says
Micro-retirement is not a recognised concept or employment status under Federal Decree Law No. 33 of 2021 on the Regulation of Labour Relations (as amended) (UAE Labour Law). As such, it reflects a voluntary work-life balance practice, rather than a recognised legal employment category, according to Dilini Loku, senior associate for law firm Gateley Middle East.
“Some companies may offer formal sabbatical policies or career break programmes; however, beyond such arrangements, there is no automatic right or statutory entitlement to extended breaks,” she explains.
“Any leave taken beyond statutory entitlements, such as annual leave, is typically regarded as unpaid leave in accordance with Article 33 of the UAE Labour Law. While employees may legally take unpaid leave, such requests are subject to the employer’s discretion and require approval.”
If an employee resigns to pursue micro-retirement, the employment contract is terminated, and the employer is under no legal obligation to rehire the employee in the future unless specific contractual agreements are in place (such as return-to-work arrangements), which are generally uncommon, Ms Loku adds.

UAE currency: the story behind the money in your pockets
Keep it fun and engaging
Stuart Ritchie, director of wealth advice at AES International, says children cannot learn something overnight, so it helps to have a fun routine that keeps them engaged and interested.
“I explain to my daughter that the money I draw from an ATM or the money on my bank card doesn’t just magically appear – it’s money I have earned from my job. I show her how this works by giving her little chores around the house so she can earn pocket money,” says Mr Ritchie.
His daughter is allowed to spend half of her pocket money, while the other half goes into a bank account. When this money hits a certain milestone, Mr Ritchie rewards his daughter with a small lump sum.
He also recommends books that teach the importance of money management for children, such as The Squirrel Manifesto by Ric Edelman and Jean Edelman.
