Residential and Commercial Sectors
Residential and commercial buildings account for 40% of energy use in the country. These buildings where we live and work are affected by policies that provide minimum construction standards that reduce energy waste, provide financing options to help pay for energy upgrades, promote advancing energy efficiency through high-performance buildings that go beyond minimum requirements and techniques for taking advantage of the latest technologies in energy monitoring and control, and that ensure that as buildings become tighter that the health and safety of occupants are maintained.

Implementation/Compliance Studies – The Building Codes Assistance Project has information on the compliance studies they have done for Kentucky as well as DOE-funded compliance studies.
► Overview of building energy codes in the Midwest
In addition to building energy codes, states and utilities are often looking for ways to take buildings "beyond code" and achieve higher levels of energy savings. Home performance programs are becoming widespread in the region and offer a good best-practices example of a next step beyond baseline building energy code for states and utilities that are interested in achieving additional energy savings in residential buildings.
