Energy efficiency top 3 essentials.

While the energy of the Universe is consistent, we always lose some when we are converting one source to another. We still have to pay for this energy, both financially and ecologically, even though it is effectively being wasted. The traditional light bulb is a good example of how energy can easily be wasted. When we turn a halogen light on, around 90% of the energy used makes heat energy rather than the light energy that we want. Energy efficiency savings can often be achieved through retrofitting existing building spaces to improve heat retention and energy use.

Common examples of improvements include:

  • Efficient Equipment

New technology is responsible for increasingly efficient equipment that operates using a much lower power supply.

Meanwhile pressure to reduce energy waste has resulted in devices that improve the conversion rate of fossil fuels – new condensing boilers that use up the latent heat produced before it is released back into the outside air, are a good example of this.

  • Thermal Insulation

In the UK building regulations define the standard that buildings should comply with in relation to thermal insulation. The external surfaces of a building are frequently the most vulnerable are in relation to heat loss. Increasing the efficiency of thermal layers by introducing cavity wall insulation, double-glazed windows and doors, carpets and wall cladding can have a significant impact on lowering heat loss and creating a more comfortable and consistent internal environment.

  • Ventilation

Ventilation is needed for removing old stale air from a building. However frequently the air contains valuable heat energy. Techniques such as fitting airtight seals around doorways and windows, sealing certain air spaces like lobbies and receptions as well as controlling ventilation systems can improve the airflow while retaining heat.

The more energy efficient your business is – the less money is wasted unnecessarily.


Often the efficiency of a building requires an initial outlay to improve existing structures or layouts. The results can be instant or they can provide a longer-term return on your investment. It is important to select the most appropriate systems for a specific building. If care is not taken to make an informed choice you could be wasting more energy (and spending more money) on systems that are unsuitable for your building and business needs.
