What makes a house energy inefficient?

House building standards in America have not been adequate in terms of dealing with energy issues simply because they were not considered issues until the cost of producing energy and associated environmental issues became a concern.
American homeowners are now faced with upgrading their homes to be more energy and cost efficient and thus providing healthier and more comfortable living environments for their families.
Energy supply, distribution and the resulting pollution is quickly becoming a very troublesome issue, especially in these economically challenged times, which is now being addressed through stricter building codes enforcing energy efficient construction of new homes.  
HOW DOES MY HOME LOSE ENERGY?
The indoor environment is isolated from the outdoor environment by the outer shell of the house – roof, walls and foundation.  90% of home energy loss occurs in these areas.  The other 10% of energy loss relates directly to lack of controls by the occupants.
Following is a list of all the areas of a home that contribute to energy loss:

Lights
Attic, Walls, Floors
Windows & Doors
Basements & Crawl Spaces
Ventilation & Ducting
Joints & Seals
Heating & Cooling Systems
Water Heaters
Landscape
