Implications of the 2015 IECC Energy Rating Index (ERI)

Building Codes Assistance Project, Jan. 2015.
http://energycodesocean.org/sites/default/files/resources/ERI_fact_sheet_2015_IECC_Final_1.pdf

"Historically, the residential International Energy Conservation Code (IECC) has offered two main ways (or paths) for builders to demonstrate code compliance: prescriptive and performance. The 2015 IECC includes a third and new compliance path–the Energy Rating Index (ERI). The ERI provides flexibility for builders, but if weakened, becomes the path of least efficiency."

Additional IECC 2013 and 2015 adoption resources are available on the BCAP website at http://energycodesocean.org/2012-and-2015-iecc-adoption-resources.

Tesla Gears Up for Charge Into Home Battery Storage Market

PV Magazine, Feb. 13, 2015, by Giles Parkinson.

"Tesla Motors, the electric vehicle company throwing down a major challenge to the global motor industry, says it is now looking to become a front-runner in energy storage in a major new challenge to the traditional electric utility business model."



New National Furnace Standards Will Save Consumers Money, But Stronger Standards Could Save Even More

ACEEE Blog, Feb. 11, 2015, by Andrew deLaski.
http://aceee.org/blog/2015/02/new-national-furnace-standards-will-s

On Feb. 10, 2015, "the US Department of Energy (DOE) issued a proposed rule for furnaces that would provide significant savings for consumers on their home heating bills, and be among the biggest natural-gas saving standards ever completed by the agency. The new standards would reduce gas and propane furnace energy consumption by about 13% relative to basic furnaces sold today."

Selling Into the Sun: Price Premium Analysis of a Multi-State Dataset of Solar Homes

Lawrence Berkeley National Laboratory, Jan. 2015.
http://emp.lbl.gov/publications/selling-sun-price-premium

"Capturing the value that solar photovoltaic (PV) systems may add to home sales transactions is increasingly important. Our study enhances the PV-home-valuation literature by more than doubling the number of PV home sales analyzed (22,822 homes in total, 3,951 of which are PV) and examining transactions in eight states that span the years 2002–2013. We find that home buyers are consistently willing to pay PV home premiums across various states, housing and PV markets, and home types."

Benchmarking the Declining Cost of Solar

Solar Today, Nov/Dec 2014, by Samantha Weaver and others. (Scroll to page 24.)

"This “entry-level” green building program is attracting builders with its low cost and easy-to-follow checklist."

DOE Zero Energy Ready Home™ Case Study

U.S. Dept. of Energy, Energy Efficiency & Renewable Energy, Nov. 2014.
http://energy.gov/sites/prod/files/2015/01/f19/DOE_ZEH_TCLegend_11-2014.pdf

TC Legend Homes, Montlake Modern, Seattle, WA
"After two years of searching for their dream home, a Seattle couple turned to zero energy home builder Ted Clifton of TC Legend Homes, who built them a modern two-story with a mother-in-law suite and views of Lake Washington from the roof-top deck. Clifton calls the home a positive energy home, one that produces more energy than the home itself consumes. In fact, the home should produce enough electricity to power an electric car with the charging station set up in the garage."

Watts in a Drop of Water: Savings at the Water-Energy Nexus

ACEEE White Paper, Nov. 5, 2014, by Rachel Young. [Free registration required to view full-text.]
http://aceee.org/white-paper/watts-in-drop-water

"This paper shows a range of energy intensities for water and wastewater services and in residential hot and cold water. We draw from existing data to develop national estimates of energy savings associated with water savings, including energy used in water conveyance, water heating, and water and sewage treatment."

Community Shared Solar: Policy and Regulatory Considerations

National Renewable Energy Laboratory (NREL), Sep. 2014.
http://www.nrel.gov/docs/fy14osti/62367.pdf

"This paper explores the ways in which the shared solar business model interacts with existing policy and regulations, including net metering, tax credits, and securities regulation. It presents some of the barriers that shared solar projects may face, and provides options for creating a supportive policy environment."
