Display Energy Certificates, known as DEC, provide an energy rating for public building such as schools and hospitals over a certain size. This A to G rating is based on the actual energy consumption for the building, so if the energy consumption decreases, the rating will improve. For the DEC shown above, the graphs on the right show that the energy rating has improved significantly each year for this building, from a G in 2012 to an E in 2014.
The DEC need to be displayed in a prominent place, so that if you walk into your local town hall or hospital you can see how much energy they consume compared to the average for that building type. They are a good way of raising awareness, and staff walking past these ratings on a daily basis may become more active in reducing their energy waste.
At the same time Leicestershire County Council's newsletter dropped through the door and the extent of cuts they are facing over the next few years as a result of austerity measures is horrendous. The cost of DEC is only a very small slice of the budget, but the focus is clearly going to be on keeping essential services going.
Whatever the responses were to the consultation document, it was already clear that there was a very negative slant towards DEC in the document, referring to them as a 'burden'. DEC have been a large part of my work for the last 7 years, but the picture painted was that they no longer had a future. I was left feeling rather gloomy, that I would inevitably have to find an alternative way to make a living.
Then some of my old colleagues kicked me back into touch. (Thanks Phil, Nick and Bryony!)
In 2008 the legislation forced DEC onto reluctant building managers. Gathering all the data needed was a pain the first few years, because in many cases energy wasn't being managed. Where energy was being managed well, the DEC seemed somewhat superfluous. But over the last 7 years building managers have adapted to using DEC as a tool. The DEC is an independent, annual energy review resulting in a visible, clearly understandable, and easily comparable energy rating. It provides useful information to help building managers make decisions on maintenance, justify investment in efficiency projects and target awareness campaigns.
I know of County Councils who use the DEC energy ratings to help them monitor the energy consumption of their buildings and to target their improvement measures - improvement measures that save them money on energy bills. They want to keep using the DEC as they are a valuable tool.
Headteachers, who have far more to worry about than tracking their complicated energy bills, can see at a glance how their school performs compared to an average school. And yes - they do check out the DEC rating in other schools that they visit! Displaying the energy rating in reception means that a poor G rating cannot be ignored, and is visible for parents, governors and teachers to see. It is a powerful motivation for making improvements.
Back in 2009 I compared how the DEC ratings I had produced had changed from the previous year. You can see that in general there was a shift towards the higher A, B and C rated certificates. The graphs above show that even in just one year there was an improvement in energy ratings, which means my clients actually reduced their energy consumption.
The above DEC is for a leisure centre, where the CHP (combined heat and power unit) was old and the efficiency was deteriorating. The effect of replacing it for a new CHP unit and additional improvements can be seen with the increase in the energy rating for the building from a D to a C. The cost saving was over £20,000 the following year, even after allowing for the effect of weather. What part the DEC played can't really be quantified, but raising the awareness and priority of energy efficiency improvements can have some significant financial benefits.
DEC aren't a financial burden, they are a money saving tool. Evidence from the Department of Energy and Climate Change, shows significant energy efficiency improvements between 2008 and 2012, which outweighs the cost of providing DEC. Shame that CLG, sees DEC as a 'burden' and wants to reduce or eliminate DEC requirements. Many of the proposed changes in the consultation would undermine DEC and make them almost useless as a tool for encouraging energy efficiency. CLG must understand that, yet they continue to push for dismantling them.
Well, if you have been following for a while, you may know that I am not a 'cut and run' type of person. If I can't make a stand and act when it is about DEC, which I am an expert on, then when will I ever make a stand on anything? So......... I have made a decision. I am not waiting for any of these bad outcomes to be enforced by people who are really rather ignorant about energy certificates.
Saving energy is hard. It is an uphill struggle, with investment seen as the lynch pin. My clients want things that are easy and that work to reduce energy consumption, and for this the current DEC aren't good enough. With some small tweaks, they could be so much better - Gold-Plated in fact, but with little to no change to the clients 'burden'.
For example, the value on the current energy certificates is a carbon ratio, quite meaningless to most people. But in the process of gathering all the energy data, I end up with all the cost data too. Displaying the cost of energy consumption as well would help understanding. As in the leisure centre example above, a £20k saving has a much bigger impact on people than seeing a C rating. Equating that cost into something real, like how many nurses or teachers that money could employ if it wasn't spent on energy, would help to hit the message home. For an individual, using the stairs instead of the lift may seem like a tiny insignificant amount of energy in a large hospital, but when that energy is equated into real people and jobs saved (or climate change and lives) it is energy that is well worth saving.
I can't change the actual DEC certificate, but I can change how it is presented and provide additional information with it. I can't change the legal requirements of DEC, but I can demonstrate the benefits of having them, and encourage voluntary DECs. Already I have clients who have decided to go beyond the minimum requirements. And as an energy assessor I always strive to provide more value than the basic energy certificates require, with advice on energy bills and added details for recommendations.
Working with my regular clients I will be setting up some trials to see what improvements to the DEC give the best results for the least additional burden. My target is that within 3 years, every DEC I produce will be a Gold-Plated. I will also make all the results and Gold-Plated DEC templates freely available for everyone to benefit from. So if you are a disenchanted energy assessor, accreditation body or building manager and want more than CLG are offering, spread the word - Gold-Plated DEC will be coming your way soon!
