Does your business comply with ESOS? Don’t leave it too late!

Posted by Paul Langford on 25/09/15 09:00

Are you a UK business with more than 250 employees? Does your business generate at least £40 million in annual turnover and have a balance sheet of more than £34 million? If the answer is yes to either question, you are required to complete an energy efficiency audit by 5 December to comply with the government’s Energy Saving Opportunity Scheme (ESOS). Should you fail to comply, you risk a fine of up to £50,000.

A cooling system that generates energy: Yes it's possible!

Posted by Paul Compton on 21/04/15 11:30

Today’s blog article is a bit different from our usual contributions: we were recently involved in an unusual project with a client who thinks very much out of the box, which resulted in an ingenious solution that we thought could be interesting for you.

Why natural ventilation is best for power generation facilities: The facts and figures

Posted by Graeme Clark on 29/07/14 11:30

In my opinion, a natural ventilation system should always be the first choice for power plants, energy from waste, biomass, hydro stations, transformer stations and other similar buildings for 2 reasons:

1) The Environment 

The number and frequency of extreme weather events has been on the increase throughout the world. The climate is changing, of that there is no doubt, and the most popular theory is that this is due to the rise in CO2 emissions.

What to do when you have a condensation problem

Posted by Paul Langford on 08/04/14 11:30

Condensation forms when humidity is so high that the air is saturated and can’t take on any more moisture. The solution to the problem is not complicated, but you need to be sure you are measuring the right variables to identify the best method to resolve it.

When does condensation become a problem?

How to deal with engine exhaust emissions when local exhaust ventilation is not an option

Posted by Paul Langford on 04/03/14 11:30

Controlling diesel engine exhaust emissions in enclosed spaces such as maintenance workshops is easily done with local exhaust ventilation (LEV), which can be as simple as fitting pipes to the vehicles’ exhausts while they are being serviced in order to draw the fumes outside. However, there are situations where this is not an option, for example in a warehouse where there is heavy vehicle movement inside the building, as vans and lorries come in and out for loading and unloading.

Why coffee roasting houses need both cooling and ventilation

Posted by Paul Langford on 04/02/14 11:30

Who doesn’t love the smell of freshly roasted coffee? But there can be too much of a good thing, and coffee roasting facilities have more to worry about than an excess of fragrance: they have to cope with the high levels of heat generated, which becomes even more of an issue during the summer months, as well as the build-up of carbon monoxide concentrations in the 72 hours following the roasting process. Efficient ventilation to extract the excess heat and carbon monoxide is essential.

Questions and answers from our 'Evaporative cooling for data centres' webinar

Posted by Laurence Cockman on 28/01/14 11:30

At our recent CPD accredited evaporative cooling webinar, I received some interesting questions in the Q&A session at the end. I would like to share my answers, which have been edited to make them clearer.

Q: How do you deal with freezing conditions?

A: During colder periods, where freezing outside conditions would be expected, the evaporative coolers would not be used, and they would have been earlier drained down and isolated as part of a winterisation process. This means that there is no chance of any water freezing inside the unit, as it contains no water.

Freezing conditions are then dealt with by carefully mixing quantities of that cooler outside air with warmer waste air from the IT equipment, therefore providing air at desirable conditions.

What is evaporative cooling? Read our White Paper to learn the facts

Posted by Laurence Cockman on 12/11/13 11:30

The benefits of evaporative cooling in warehouses and industrial buildings are many: it is a highly energy efficient technology, that uses no refrigerants, provides a pleasant indoor climate, is simple and easy to maintain and, last but not least, running costs are four to seven times lower than traditional air conditioning solutions – and they are even lower in data centres.

Evaporative cooling and elephants: debunking common misconceptions

Posted by Laurence Cockman on 05/11/13 11:30

Evaporative cooling (also known as adiabatic cooling), is an extremely efficient and cost effective means of cooling. It is particularly well suited to warehouses, data centres and other industrial buildings where the manufacturing processes generate relatively high levels of heat.

How to boost your ventilation system’s cooling capacity

Posted by Paul Langford on 30/11/12 09:47

As a factory manager you may find that in spite of having done everything to keep your mechanical ventilation system in perfect condition, the temperature in your plant or in parts of it is getting higher. Over the years, the use of your factory building may have changed: for example, with the introduction of lean manufacturing practices, there may be a higher density of production machinery with consequent higher heat load in some areas of your facility, so that the system as it was originally designed and installed is not as effective as it used to be.

Improving energy efficiency in data centres with evaporative cooling

Posted by Paul Langford on 20/06/12 08:43

Data centres tend to be energy guzzlers, using vast amounts of power not only for running the equipment, but also for maintaining the temperature and humidity at the levels required by the servers for them to be able to operate correctly.

Heating a boiler room when temperatures drop below zero

Posted by Graeme Clark on 12/06/12 11:34

Boiler rooms need to be ventilated even when the outside temperature drops below zero, which means bringing in freezing air. These are typically unmanned areas, so it is acceptable for them to be colder than usual. However, very low temperatures could cause issues to the process equipment, such as freezing pipes or condensation.

What is the best way of ensuring the internal temperature at low level doesn’t drop too low? There are different options, depending on the building.

Why attenuation shouldn’t be an afterthought

Posted by Paul Compton on 31/05/12 09:59

If you are in the early stages of designing a ventilation system for a power generation plant, have you already thought about attenuation? Is the power plant near a residential area? Do you need to ensure that the ventilation system doesn’t allow unacceptable noise levels to come out of the building? It is important to make these considerations early on, as attenuation can have a big impact on the design.

The world’s first natural ventilation solution in a television studio

Posted by Paul Compton on 27/02/12 11:18

Television studios aren’t obvious candidates for natural ventilation, with the vast amounts of heat generated by the lights, cameras and equipment, and the need for acoustic insulation. Yet that was the choice BSkyB made for their new production centre in West London, Harlequin 1, which boasts the world’s first naturally ventilated TV studios.
