Data Centres and Energy



When it comes to keeping its cool, Custodian is well and truly ahead of the pack. With racks of hardware utilising vast scales of power, the immediate priority for a data centre is to control the climate in order to sufficiently cool the equipment within its care, and striking a balance between boasting the latest cooling technologies and adopting an eco-friendly approach to efficiency can be a struggle for colocation facilities.

At Custodian, former Green Data Centre of the Year at the Data Centre Leaders Awards, a revolutionary evaporative adiabatic cooling system is the answer. In fact, the eco-conscious brand is able to completely negate the need for mechanical cooling, providing a positive impact for both the company’s efficiency and the wider environment.

For 95% of the year, the data centre utilises fresh air cooling, brought in from outside and filtered to clean room standards to eliminate contamination, passing into the data centre via a bank of multiple fans. In the event that British temperatures soar beyond a set threshold, the evaporative adiabatic system comes online.

A reverse osmosis plant purifies water which the system then uses to produce a very fine mist. Within a large chamber, this moisture is used to raise the humidity of the slow moving air which passes through, decreasing its temperature. The adiabatic system also acts as a room humidifier, and is supported by dual water mains, ensuring that it is resilient against mains failure. This approach is 2N resilient, with completely separate duplicate systems protecting against failure should one element be affected by outage or technical difficulty.

Further adding to its green credentials, the heat produced as a by-product of the extraction system is recycled within the site of the Maidstone Television Studios, where Custodian is based. Situated in the county of Kent, known as the Garden of England, the data centre’s location does more than provide a picturesque view; this location offers a cleaner level of air quality, actually increasing the lifecycle of the filtration equipment used within this cooling method.

In addition to its environmentally friendly credentials, this cooling system still allows Custodian to operate within a Class A classification of cooling for high density computing, a premium ‘always on’ level at which uptime and equipment protection are paramount. An industry-leading solution, this fresh air cooling system was built in partnership with Carel, an advanced solution that for Custodian, outweighed even the benefits of a fresh air over wetted media system.

Of the choice, Custodian CEO Rowland Kinch says “Wetted media didn’t react quickly enough, I was convinced that adiabatic was the way to go. I’d much rather be ahead of the curve than behind it, but I didn’t want to take any risks in terms of quality.”

And for Custodian, adopting an eco-friendly approach to cooling doesn’t mean a compromise on performance. “Adiabatic proves that the green solution can also be the most resilient and most efficient option,” explains Head of Sales, Leonard Kay. He continues, “Our ideology is to reduce our impact on the environment in a way that also offers tangible benefits to customers.”

A Good Look At How Homes Will Become More Energy Efficient Soon




energy efficient homes

Everyone always talks about ways they can save energy at home, but the tactics are old school. They’re only tweaking the way they do things at the moment. Sealing holes in your home isn’t exactly the next scientific breakthrough we’ve been waiting for.

There is some good news because technology is progressing quickly. Some tactics might not be brand new, but they’re becoming more popular. Here are a few things you should expect to see in homes all around the country within a few years.

1. The Rise Of Smart Windows

When you look at a window right now it’s just a pane of glass. In the future they’ll be controlled by microprocessors and sensors. They’ll change depending on the specific weather conditions directly outside.

If the sun disappears the shade will automatically adjust to let in more light. The exact opposite will happen when it’s sunny. These energy efficient windows will save everyone a huge amount of money.

2. A Better Way To Cool Roofs

If you wanted to cool a roof down today you would coat it with a material full of specialized pigments. This would allow roofs to deflect the sun and they’d absorb less heat in the process too.

Soon we’ll see the same thing being done, but it will be four times more effective. Roofs will never get too hot again. Anyone with a large roof is going to see a sharp decrease in their energy bills.

3. Low-E Windows Taking Over

It’s a mystery why these aren’t already extremely popular, but things are starting to change. Read low-E window replacement reviews and you’ll see everyone loves them because they’re extremely effective.

They’ll keep heat outside in summer or inside in winter. People don’t even have to buy new windows to enjoy the technology. All they’ll need is a low-E film to place over their current ones.

4. Magnets Will Cool Fridges

Refrigerators haven’t changed much in a very long time. They’re still using a vapor compression process that wastes energy while harming the environment. It won’t be long until they’ll be cooled using magnets instead.

The magnetocaloric effect is going to revolutionize cold food storage. The fluid these fridges are going to use will be water-based, which means the environment can rest easy and energy bills will drop.

5. Improving Our Current LEDs

Everyone who spent a lot of money on energy must have been very happy when LEDs became mainstream. Incandescent light bulbs belong in museums today because the new tech cut costs by up to 85 percent.

That doesn’t mean someone isn’t always trying to improve on an already great invention. The amount of lumens LEDs produce per watt isn’t great, but we’ve already found a way to increase it by 25 percent.

Maybe Homes Will Look Different Too

Do you think we’ll come up with new styles of homes that will take off? Surely it’s not out of the question. Everything inside homes seems to be changing for the better with each passing year. It’s going to continue doing so thanks to amazing inventors.

IEMA Urge Government’s Industrial Strategy Skills Overhaul To Adopt A “Long View Approach”



IEMA, in response to the launch of the Government’s Industrial Strategy Green Paper, have welcomed the focus on technical skills and education to boost “competence and capability” of tomorrow’s workforce.

Policy experts at the world’s leading professional association of Environment and Sustainability professionals has today welcomed Prime Minister Teresa May’s confirmation that an overhaul of technical education and skills will form a central part of the Plan for Britain – but warns the strategy must be one for the long term.

Martin Baxter, Chief Policy Advisor at IEMA said this morning that the approach and predicted investment in building a stronger technical skills portfolio to boost the UK’s productivity and economic resilience is positive, and presents an opportunity to drive the UK’s skills profile and commitment to sustainability outside of the EU.

Commenting on the launch of the Government’s Industrial Strategy Green Paper, Baxter said today:

“Government must use the Industrial Strategy as an opportunity to accelerate the UK’s transition to a low-carbon, resource efficient economy – one that is flexible and agile and which gives a progressive outlook for the UK’s future outside the EU.

We welcome the focus on skills and education, as it is vital that tomorrow’s workforce has the competence and capability to innovate and compete globally in high-value manufacturing and leading technology.

There is a real opportunity with the Industrial Strategy, and forthcoming 25 year Environment Plan and Carbon Emissions Reduction Plan, to set long-term economic and environmental outcomes which set the conditions to unlock investment, enhance natural capital and provide employment and export opportunities for UK business.

We will ensure that the Environment and Sustainability profession makes a positive contribution in responding to the Green Paper.”
