An ACEEE analysis released today finds that energy efficiency and solar make complementary energy and carbon reductions in new home construction, but when budgets are tight, efficiency needs to come first. Throughout the United States, energy efficiency is more cost effective. Each month, it delivers $4 to $32 in net savings while rooftop solar alone can cost up to $14.
New ACEEE research shows that Florida could bolster energy efficiency policies to gain 135,000 jobs, making the state’s economy a bit sunnier.
Zero energy building codes are making inroads in Oregon, California, British Columbia, and other places, but a new ACEEE white paper reveals that they still face barriers to nationwide success, including a “solar-only” mentality.
The Atlantic hurricane season is just beginning, and experts are predicting another active year.
Washington, DC—As more states struggle with extreme weather events, the 2017 State Energy Efficiency Scorecard gives state-level policymakers a road map for building stronger and more-resilient communities. This 11th annual report from the American Council for an Energy-Efficient Economy (ACEEE), released today, shows which states are doing the best on energy efficiency — a critical tool for withstanding and recovering from storms and economic shocks.
Next week we will release the 2017 City Energy Efficiency Scorecard. Because it’s been two years since we published the last edition, here are some key scorecard numbers and facts to jog your memory about its contents.
100: Number of points cities could earn. No city came close to earning a perfect score in a past scorecard. Spoiler alert: it didn’t happen this time either.
Five years ago, ACEEE found that energy efficiency could reduce projected 2050 US energy use by 40–60%. As a result, ACEEE established a strategic goal to reduce projected 2050 energy use by 50%. We thought it was time to check on our progress and ask whether our goal still seems reasonable. We find that energy use has been stable in recent years, reversing historical growth, a very positive development that is due in significant part to increasing our energy efficiency.
Do you know which government in the United States is the biggest laggard on energy codes for homes? The federal government. But that’s about to change.
Manufactured homes and the “HUD Code”
Although building codes are mostly set by states, the federal government sets codes for manufactured homes (sometimes called mobile homes) because the factory does not always know where a home will end up. Manufacturers shipped 70,519 homes in 2015, more than the number of single-family homes built in any state except Texas.
Building codes have protected people with minimum health and safety requirements for buildings since the Code of Hammurabi in 1754 BCE. Energy provisions in US codes have protected owners and tenants from excessive energy waste since the 1970s. They set minimum performance levels for energy features in new buildings and renovations, notably insulation, windows, air sealing, and to some extent, lighting and heating and cooling equipment.
