Otherwise you can hire an 'external auditor' that has been trained for such purpose and are well-equipped for the assessment. They have the blower doors and infrared cameras to assess the loss of cooling and heat from a house. Any hidden holes and cracks are detected. These auditors check the walls, ceilings, doors and every other prospect that can contribute to energy conservation. But attic can only perform this key purpose if it is insulated properly. The attic door should also be sealed make sure that air from the house is not going through it and vice versa. Weather strippers are best to seal the attic door. 3. Securing leaks around your house will also aid you in controlling energy lost. Leaking ducts can cause more power consumption because your heating system has to work 30% more than normal. This will result in more energy loss and hence, increase in your electric bill. Approximately quarter of the bills goes to the lighting and other electric appliances. So, you should also try to control the useless consumption of lights and electronic appliances. The thermostat will automatically turn on with single phone call. There is no life without water. Water consumption should be optimal. It facilitates you to lower your bill. There are some energy devices that will facilitate you with optimum water consumption. One most important device is low- flow showerhead. If you are thinking that after spending whole day at office how come your house consumes this much electricity, then the doubt is justified to some extent but let's just take a look at what causes high bills. On first position lie the electric appliances that aren't switched off even when not needed. Any gap left around the wall enclosure will deteriorate the quality of the insulation i.e. around electrical boxes, pipes and wires. The alternative in this situation might b cellulose insulation which eliminates gaps and voids making the walls 100% insulated. This is not all. Air sealing- Leaks around the house are responsible for 40% of our heating or cooling consumption which means that no matter how good is your insulation, if it has leaks you cannot assure total savings.
