Energy usage of your house is a huge chunk of your annual earnings.
An energy efficient house will shave off a substantial portion of this.

Is it only the householder who will benefit from the improved home energy efficiency?
The fact is energy is a pressing issue the world over.
When your house is energy efficient it will have beneficial impact on several other related issues down the line such as the countries economy,
reduced dependence on imported fuel (which are limited non-renewable resources), availability of funds for other development work,
more employment for the local skilled personnel and not forgetting the reduction in the universally dreaded green house gas emissions.

Unfortunately non renewable energy consumption also is responsible for acid rains, radioactive by products,
oxides of carbon, nitrogen and sulphur, all of which are certainly not friendly towards our battered environment.

Using energy more efficiently around the house may seem easy, by turning the thermostat down, insulating the attic, and so on, but it’s more complicated than you may think. Air leakage is the biggest problem in most homes. Particularly in older homes, air exchange is vital in controlling air quality and humidity.
