Evaluate Effectiveness of Insulation
Installing cavity wall or loft insulation is one of the most cost effective methods of preventing the loss of air from a building which has been deliberately heated or cooled by equipment which more than likely consumes electricity. By preventing the loss of this air to the outside world, there will not be the need to re-heat or re-cool more air, which has the beneficial effect of both saving money for the household or business concerned, not to mention being kind to the environment as less power is consumed which will often be created through burning fossil fuels which releases harmful pollutants into the atmosphere.
Once insulation has been installed and put in place, many people will think that they have exhausted and completed this particular method of reducing energy consumption and that it needs no further thought. Whilst there is no doubt that any amount cavity wall or loft insulation will make a positive contribution in terms of reducing heated or cooled air loss, it is important that it is not forgotten about and is evaluated to assess its effectiveness to determine if it could be further improved.
For example, it may be the case that a particular amount of insulation has been laid in the loft or attic but it is not as thick as it could be and there is still some air escaping which could be prevented through the laying of additional or thicker insulation. Loft insulation should also be regularly inspected to check that it has not shifted position or been damaged, in particular through animals such as squirrels or racoons which are a common occurrence in many buildings in the countryside as they seek shelter inside and find a gap in the roofing. They can rip and damage the insulation and cause large gaps which greatly reduce the overall effectiveness of the insulation.
Putting insulation in place is just one of many relatively quick, simple and inexpensive ways in which businesses and households can reduce their environmental impact. Whilst it will not be as cheap and easy as replacing a traditional light bulb for an energy efficient one, it is compared to other methods such as installing a wind turbine or converting machinery to run on bio-fuels. Similar to health and safety procedures, it should be regularly assessed and evaluated to ensure that it is still effective and carrying out its intended purpose to a sufficient and expected level.
