Thermal Bypasses Can Thwart the Best HVAC Systems

IE3 (Indoor Environment & Energy Efficiency), Mar 12, 2015, by Allison Bailes III.
http://www.ie3media.com/thermal-bypasses-can-thwart-best-hvac-systems/

"It seems so simple. There’s outside, and there’s inside. The walls, ceilings, and floors that separate the cold outside from the warm inside should be the only surfaces that rob heat from a home. Interior walls have conditioned space on both sides, so they shouldn’t be a problem, right?"

ACCA Initiates New Standard On HVAC System Design For Energy Efficient Homes

Air Conditioning Contractors of America (ACCA) Press Release, Mar. 23, 2015.
http://www.acca.org/release/acca-initiates-new-standard-hvac-system-design-energy-efficient-homes/

"The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announces the initiation of development of BSR/ACCA 16 Manual E-201x, “HVAC System Design for Energy Efficient Homes” as a new industry standard. This standard will provide procedures to design/select HVAC systems and equipment for low-load homes that will achieve satisfactory indoor conditions with lower equipment capacity; i.e., resolving ventilation and moisture requirements/issues with low air volume systems while addressing occupant comfort, health, and safety."

"ACEEE celebrates its 35thanniversary this year. To commemorate that milestone, we’ve updated the design of our online home, aceee.org, to include larger, darker text, a simpler layout, and bigger images."

Shelter Report 2015: Less Is More: Transforming Low-Income Communities Through Energy Efficiency

Habitat for Humanity, Jan. 2015.
http://www.habitat.org/advocate/publications-resources/shelter-report-2015

"Habitat for Humanity’s 2015 Shelter Report focuses on improving energy efficiency among lower-income households.  Although Habitat for Humanity and the federal government are addressing some of the energy efficiency issues among lower-income families, too many families still face the challenge of energy costs that are excessive compared to their overall incomes."

Implications of the 2015 IECC Energy Rating Index (ERI)

Building Codes Assistance Project, Jan. 2015.

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 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."
