Efficiency in heating and cooling comes from control and monitoring. To make a heating and cooling system function at its maximum efficiency, you must break the system down into as many small systems as economically feasible and reduce the amount of ductwork by as much as possible. Think about it like the lights in a house. Imagine that your home only had one light switch controlling all the lights in the home. Although it would be convenient it would not be efficient. This is predominately how we heat and cool our homes. Most people go to a single thermostat on the wall and set it to a temperature that can only be monitored from that single location. Imagine the inconvenience to the occupants of the home if the analogy of the single light switch were really true.  

 Now imagine that the heating and cooling system functioned like the light switches in most of our current homes. Each room would have its own thermostat for the comfort of that space. The occupant would be able to adjust the temperature to their liking. If the space is not frequently used, like a guest bedroom or a formal dining room, the thermostat could be off altogether. When one bedroom has a south west exposure with large windows, and another bedroom has a north east exposure with fewer windows, wouldn't it make sense for those two spaces to have individually controlled systems. Do I even need to discuss bonus rooms and the inherent cooling problems they create- thats for another post.

There is a lot to understand about the mechanical systems in a residential home. Most builders will not take the time to investigate and educate themselves or their clients. Most builders will follow the status quo. Here is some brief information to check out on the type of system I prefer for the homes I build. To my clients: I am not going to force you to use systems you are not familiar or comfortable with. I will simply do my best to educate you on the benefits of the system I would chose for myself, and give you the knowledge I have accumulated through my extensive research.
