The 2018 State Energy Efficiency Scorecard, now in its 12th edition, ranks states on their policy and program efforts, not only assessing performance but also documenting best practices and recognizing leadership.

In order to achieve long-term targets for energy savings and emission reductions, substantial savings will be needed from existing buildings.

In 2014, the U.S. Department of Energy (DOE) issued a FOA (Funding Opportunity Announcement) to conduct residential energy code field studies using a radically different methodology from previous studies. Historically, studies defined and measured “compliance” as the portion of all code requirements being met on a house-by-house basis.

Buildings consume about two-thirds of the United States’ power supply and produce about 40 percent of carbon emissions. Buildings that are being constructed now will have a considerable impact on our region’s energy use 50 to 100 years from now. Thus, the built environment, including residential, commercial, and public structures, presents an opportunity to drastically reduce carbon emissions.

Residential and commercial buildings are among the largest users of energy in the United States, accounting for approximately 51 percent of all energy consumption in 2017. Because this represents such a significant portion of our energy use, policies have been put into place that govern the way buildings and homes use energy.

Currently, 37 states, covering almost 90% of the US population, have adopted at least the 2009 International Energy Conservation Code (IECC). Adoption is only the first step to more efficient buildings. To generate the promised energy savings, builders need to comply with the code.

While government policies aim to increase residential energy efficiency, policymakers know little about the efficiency of the U.S. housing stock and improvements in efficiency over time. This paper estimates the average space heating efficiency of U.S.

Rigorously enforced stringent building codes can cost effectively achieve energy savings, reduce energy bills and curb greenhouse gas emissions.

Buildings consume nearly 40% of primary energy production globally. Certified green buildings substantially reduce energy consumption on a per square foot basis and they also focus on indoor environmental quality. However, the co-benefits to health through reductions in energy and concomitant reductions in air pollution have not been examined.

  • Validated swimming pool and collector model, good agreement with experimental data.
  • Solar pool heating system performance optimized based on COP (energy ratio).
  • Optimized system achieves pump energy savings of approximately 60%.
  • System produces enough pressure to keep the vacuum relief valve closed.
  • Potential for 180 GWh of electricity & 150 kt of CO2 savings per year in Australia.

Solar desiccant air-conditioning is an emerging technology that offers the promise of reducing reliance on grid connected electricity for providing comfort air-conditioning. Development of a method of assessing the seasonal energy savings of these devices would enable a fair comparison with alternative devices. This could be used in policy support mechanisms to assist industry growth.
