Residential buildings use approximately 22% of the total energy
consumed in the U.S. The objective of this project is to
increase the energy efficiency of the residential building
sector by reducing the uncertainties in tools and techniques
that are currently used to make energy predictions during three
phases of a building’s lifetime: construction/design, regular
operation, and retrofit. Objective: To improve estimates of
residential whole-building energy consumption by 2014 through
characterization of uncertainties of tools used in modeling
whole buildings in support of national energy efficiency
standards, providing energy feedback to building occupants, and
selecting retrofit options to improve the performance of
existing buildings. What is the new technical idea? Providing
measures for residential energy use on a whole building scale is
challenging because of the interacting components and systems
that come into play. As these building components and systems
increase in efficiency, a holistic assessment
