Look around your place of work. How much thought did you give to the energy efficiency of the equipment you use before you bought it?
The truth is we often tend to focus on the initial price –or be seduced by the appearance and design of equipment – and forget to think of efficient energy use as a big part of its lifetime cost.
Sometimes, spending a few pounds more on efficient lighting might save us an impressive amount of money in the long run.
More efficient lighting pays back quickly in areas that see long daily use – for example, hotel corridors, shops with long opening hours and 24/7 car parks. Choose high efficiency strip lighting, LED lighting or high pressure discharge lighting (sodium or metal halide) to make savings.
Install a high efficiency condensing boiler. These convert gas to heat with less than 10% waste – where older boilers can lose over 30%1 . Once you have an efficient boiler with fine control, make sure you’re feeding it the lowest priced energy you can.
Before choosing a new computer and screen, check its efficiency rating. This will have a long term influence on running costs. So as well as checking speed and performance, look out for better energy efficiency too.
Motors are generally efficient devices, but as their power to cost ratio is high, choosing a motor that offers just a small percentage higher performance can pay back quickly.
Refrigeration and air conditioning
Older refrigeration and air conditioning equipment is invariably more expensive to run. Modern equipment benefits from better insulation and more efficient components, making savings of 15-20% in running costs achievable2.
