Energy Savings from Small Near-Zero-Energy Houses

Integration of whole-house construction technologies in small, affordable, super-efficient houses

This technology installation review provides an overview of the construction and monitoring of four small single-family houses that achieve dramatic reductions in energy consumption and approach the goal of “net zero energy use.” (A net-zero-energy building is one that produces as much energy from solar panels as it consumes over a year.) This study discusses the construction methods, building products, appliances and equipment, and data collection methodologies used in the houses and provides data on energy savings gathered through the monitoring effort.

The Potential Impact of Zero Energy Homes

This study presents a far-reaching outlook into the possibilities for Zero Energy Home (ZEH) technologies in the new home market and their potential impact on U.S. energy consumption through 2050. Zero Energy Homes, which are connected to the utility grid, combine highly energy- efficient design and technology with solar electric and thermal systems to produce as much energy as they use on an annual basis.

This study examines three scenarios for the adoption of ZEH into the single-family home market and the effect of each scenario on residential energy consumption through 2050. A reference case, where household energy use remains relatively constant from today’s usage levels, serves as a basis for comparison.

S. Horowitz | University of Colorado

The U. S. Department of Energy’s Building America residential systems research project uses an analysis-based system research approach to identify research priorities, identify technology gaps and opportunities, establish a consistent basis to track research progress, and identify system solutions that are most likely to succeed as the initial targets for residential system research projects.

This report describes the analysis approach used by the program to determine the most cost-effective pathways to achieve whole-house energy-savings goals. This report also provides an overview of design/technology strategies leading to net zero energy buildings as the basis for analysis of future residential system performance.
