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.

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."

Your Own Energy “Island”? ORNL Microgrid Could Standardize Small, Self-Sustaining Electric Grids

Oak Ridge National Laboratory, Oct. 2014, by Katie Jones.
http://www.ornl.gov/ornl/news/features/2014/a47cc734-54f3-4aec-95ba-df1bbbdb25ad

"Microgrids are designed to not only continue power to local units such as neighborhoods, hospitals or industrial parks but also improve energy efficiency and reduce cost when connected to the main grid. Researchers predict an energy future more like a marketplace in which utility customers with access to solar panels, battery packs, plug-in vehicles and other sources of distributed energy can compare energy prices, switch on the best deals and even sell back unused power to utility companies. However, before interested consumers can plug into their own energy islands, researchers at facilities such as ORNL’s Distributed Energy Control and Communication (DECC) lab need to develop tools for controlling a reliable, safe and efficient microgrid."

Vacuum Steam Heating: Past, Present...Future?

District Energy, Fourth Quarter, 2014, by Igor Zhadanovsky.

"Every so often, a technology that had been abandoned for a long period of time comes back to life thanks to new developments that make it viable and competitive once again. While it's too early to predict with certainty, this may be the pattern that we see for one of the heating industry's oldest technologies: vacuum steam heating. This article describes the evolution of that technology, its benefits and drawbacks, and a new approach that may make it a cost-effective option in the 21st century.

Zeroing In [on Zero Energy]

Building Science Insights, Building Science Corporation, by Joseph Lstiburek.
http://www.buildingscience.com/documents/insights/bsi-081-zeroing-in/

"So what does “net zero” mean anyway? And what is the difference from a “zero energy house”? A zero energy house is “off grid” and makes all the energy it needs on site using renewables. This is not easy to do and typically involves an ultra efficient house and energy storage. Good luck. Having said that, I like the ultra efficient part. I can’t help it. Engineers worship efficiency. The storage part worries me."
