California Meets Carbon Emissions Goal Early

Posted on July 16, 2018 by Scott Gibson

California has successfully reduced carbon emissions to 1990 levels, beating its goal by four years.

The Sacramento Bee reported that according to the California Air Resources Board, emissions dropped to 429 metric tons in 2016, a decline of 12 million tons from a year earlier and enough of a decline to meet the state's climate change objectives.

Colorado’s Low-Income Solar Model

Posted on July 13, 2018 by Scott Gibson

Colorado is expanding its energy assistance efforts to make solar electricity available to more low-income households. The state is using a systematic approach that experts say could be a "clear roadmap" for other states.

China is Alleged Source of Illegal Blowing Agent

Posted on July 10, 2018 by Scott Gibson

Researchers earlier this year said were surprised to find atmospheric levels of a banned blowing agent used in the production of spray polyurethane foam were much higher than expected. All they could deduce was the source was somewhere in East Asia.

Concern Mounts Over Natural Gas Leaks

Posted on July 5, 2018 by Scott Gibson

The amount of methane leaking into the atmosphere from gas and oil operations in the U.S. is far higher than official government estimates, putting at risk the environmental advantages of burning natural gas over coal to make electricity.

A study published in the journal Science last month reports that emissions of the powerful greenhouse gas are roughly 60% greater than what the Environmental Protection Agency thinks they are.

U.S. Green Building Council Names Award Recipients

Posted on July 3, 2018 by Scott Gibson

The U.S. Green Building Council has named a high-performance house in a Decatur, Georgia, historic district as its 2017 Outstanding Single-Family Project.

The house will be familiar to Green Building Advisor readers. Carl Seville, who built and owns the 2,646-square-foot, two-story home, is a longtime GBAGreenBuildingAdvisor.com author who detailed the ups and downs of this home's construction in a series of posts beginning in 2016.

Water Heaters Get a New Performance Standard

Posted on June 29, 2018 by Scott Gibson

The Department of Energy has updated its testing and labeling standards for residential water heaters, replacing Energy Factor (EF(EF). Efficiency measure for rating the energy performance of dishwashers, clothes washers, water heaters, and certain other appliances. The higher the energy factor, the greater the efficiency. In some appliances EF reflects the percentage of energy going into the appliance that is turned into useful energy.) with a new metric called the Uniform Energy Factor (UEF).

Manufacturers say there's nothing different about their water heaters, only the way the government requires performance data to be collected and reported. Consumers shopping for a hot water heater by using the familiar yellow Energy Guides will see more detailed information than in the past.

Philips Produces a Super-Efficient LED

Posted on June 27, 2018 by Scott Gibson

Three years ago, while researching lighting options for a building he was renovating, Aaron Birkland came across something he hadn’t seen before: an LEDLight-emitting diode. Illumination technology that produces light by running electrical current through a semiconductor diode. LED lamps are much longer lasting and much more energy efficient than incandescent lamps; unlike fluorescent lamps, LED lamps do not contain mercury and can be readily dimmed. filament light bulb. He described it in a detailed blog at GBA, explaining the bulb's new approach to using LED chips and reporting an amazing efficiency of nearly 120 lumens per watt (lm/w).

United Nations Targets Inefficient Light Bulbs

Posted on June 21, 2018 by Scott Gibson

Regulators in the U.S. and Europe are winning their war on inefficient light bulbs as halogens and incandescent bulbs are being replaced by more efficient alternatives. Globally, sales of incandescent bulbs have dropped by more than 80%, from 12 billion bulbs a year to 2 billion.

Tech Company Advances Mass Timber Construction

Posted on June 19, 2018 by Scott Gibson

A three-year-old technology company named Katerra is looking to upend the construction industry. Katerra has acquired Michael Green Architecture, a well-known firm specializing in mass timber designs, and is now building a 250,000-square-foot factory in Spokane that will produce cross-laminated timber building components.

Energy Demand for Space Cooling Surges

Posted on June 15, 2018 by Scott Gibson

Today, most of the world's air conditioners are concentrated in a handful of affluent countries, but a sharp increase in demand will triple the amount of energy used for space cooling by 2050 and require new generating capacity equal to what's produced in the U.S., Japan, and the European Union today.
