In hot, humid climates, home designs should aim to reduce summer heat gain as the first priority.

Some of that heat is transferred (through conduction, convection, and radiation) into the home, which means your air conditioner has to operate longer and harder. It’s much more energy efficient to stop the heat from entering your home

Understanding Dissimilarities in Different Kinds of Homes: Mobile, Manufactured, Modular, and Factory-built, for Home Energy Efficiency

Reviewed and Revised on 01/03/2014
