Energy audits reveal the true opportunity in insulating in industry

This week is Sustainable Energy Week in Brussels where the European Commission and other stakeholders will discuss ways to help the EU reach its energy and climate ambitions through sustainable energy initiatives. Knauf Insulation believes that one good place to start is industrial insulation.

A recent report from Eiif reaffirms the cost-effective energy savings potential of industrial insulation.

The research found the plants were losing out on yearly energy savings of more than 750,000MW/h adding up to an emission reduction potential of more than 500,000 tonnes of CO2 — the annual equivalent emissions from 110,000 cars.

The audits, known as Technical Insulation Performance Checks or TIPCHECKS, also revealed that the investments for remediating insulation deficiencies paid back in less than one or two years, resulting in a total cost saving potential of at least €23.5 million.

As a result of the TIPCHECK audits, a total of 75% of the plants audited were either planning to invest in improved insulation or had done so already, the survey said.

The findings are highlighted in a new report — Harnessing The Potential of Industrial Insulation — published by the European Industrial Insulation Foundation (EiiF) which created the TIPCHECK programme and features data from audit case histories (see below).

Barry Lynham, Group Director of Strategy and Communication, at Knauf Insulation, which is a member of Eiif, said: “Imagine the benefits we would enjoy if tens of thousands of industrial plants were audited by TIPCHECK not just 180?"

“We would save billions not millions of euros, we would start to reduce our reliance on energy imports, begin to really tackle climate change across Europe and significantly contribute to making our industries more competitive."

“What is important about this report is that it highlights the cost and effective pay-back of industrial insulation using real case histories and real data. It should be required reading for every decision maker at every industrial plant in Europe.”

Dominique Ristori, Director-General for DG Energy at the European Commission, said: “The survey findings demonstrate the usefulness of standardised thermal energy audits as well as the cost-effectiveness of remediating problems with industrial insulation to save energy and reduce emissions.”[i]

Three case studies highlighted by the new Eiif report

At an ArcelorMittal plant in Belgium the TIPCHECK audit found that insulation of valves and flanges in areas of key heat lost could reduce plant energy costs by more than €28,000 per year with a pay-back period of eight months. Now the company is requesting more audits at the plant.

At the Suiker Unie processing plant in The Netherlands the TIPCHECK audit showed that an insulation investment of €84,000 could save €37,000 every year with a pay-back period of two years. An insulation strategy is now being implemented.

At a refinery in Italy the TIPCHECK audit found that without insulation on a large oil storage tank the company faced an energy loss of €430,000 every year. The owner insulated the roof and the payback period was less than two years.

The Beginners Guide To Pipe Insulation: Getting to grip with the basics

Our Beginners Guide series of blogs will look at the common areas of pipe insulation lagging that you will want to look at when choosing your product. This guide will be of most interest to the DIY installers, but some of our later guides will cover more complex products and areas of application.

One of the things we get asked about a lot is what the dimensions quoted for pipe insulation actually mean. You will always see three measurements quoted when describing pipe insulation; Wall Thickness, Bore Size and Length.

In the below diagram, A is the "Bore" and B is the "Wall".

Wall thickness is very simply how much insulation you have; so for example if you have 13mm Wall pipe insulation, then that means you have 13mm of insulation on either side of your pipe. This thickness is very often one of the most important part of your decision; too thin and you might not get the results you are looking for but too thick and it might not fit between your pipe and the wall.


The Beginners Guide to Pipe Insulation: Flexible Foams

Next up in the series we are doing on pipe insulation is "flexible foams"; a category that includes polyethylene and expanded nitrile rubber.

Polyethylene Pipe Insulation
Climaflex pipe insulation is the UK's leading brand for polyethylene pipe insulation. This is the grey foam that most people are familiar with, the kind you would traditionally find in garden centres for example. Polyethylene is the cheapest, widely available product in the market. People very often wrongly assume cheap means poor quality, this is not the case with a brand such as Climaflex. It has a thermal conductivity of 0.034 W/m.K at 0°C which is broadly equal to that of any other flexible foam, and it also has a much higher "μ factor" than other foams, making it more resistant to moisture ingress. These facotrs make it ideal for use around the home, being easy to work with and providing good insulation. 
The material can be purchased in 1m and 2m lengths, and is available in wall thicknesse…

Frost protection for domestic pipes

With the cold weather approaching we thought it would be a good idea to touch on how best to protect your pipes from frost this winter.

When dealing with frost protection on pipes inside a building your aim with insulating them is to delay the onset of freezing for as long as possible; it is not possible to guarantee a pipe will not freeze by insulation alone. The better the insulation, and the thicker the insulation, the longer you will give yourself. Under normal circumstances you aim to give yourself about 8-10 hours protection against sub zero temperatures. With pipes inside a home this is usually long enough to be sure the pipes will not freeze.

Ice formation inside the pipes will lead to an increase in pressure. As the water tries to flow this pressure will increase, and eventually will lead to the pipes bursting. A burst pipe can cause a lot of problems, not least of which is a lot of damage to your property and a lot of expense incurred.

Water regulations state that all water …
