America’s Largest Net Zero Plus Building

By Roy L Hales

The first zero net energy building in the United States was erected at the beginning of this century. In California this standard has penetrated the residential market and every new home will have to produce as much energy as it consumes by 2020. The Net Zero Plus Electric Training Institute (NZP-ETI),  in Greater Los Angeles, goes further. America’s largest net zero plus building is expected to generate an additional 185,000 KWh of electricity by the end of year one.

Riverside Energy Systems Shows BC’s Solar Potential

By Roy L Hales

Screen shot 2014-03-18 at 3.43.47 PMAccording to Dave Egles’ study, the Potential for Solar Power in British Columbia: 2007 to 2025, BC’s climate is much more amenable to solar than either Germany’s or Japan’s. The average production of a PV solar array in Kamloops, for example, is 1160 kWh/kW of PV installed. Even Vancouver (1009) has much more solar potential than Tokyo (885) or Berlin (only 848).  One of our readers has provided more recent data that shows the last two figures are probably too low (see comments, below), but it is obvious BC has a great deal of untapped potential.

By Roy L Hales

Screen-shot-2014-03-18-at-3.43.47-PM1A press release about San Diego’s first Zero Net Apartments was issued two days ago. The 338kW solar installation, of panels made by Kyocera Solar Inc., will provide 100% of the electricity needed by H.G. Fenton Co.’s 114-unit  Solterra EcoLuxury Apartments in San Diego’s Scripps Ranch suburb. In addition to being San Diego’s first net-zero apartments, Solterra is the first in the US to give tenants instant access to their energy consumption via smartphone, enabling them to adjust their thermostats remotely and is incorporating energy-efficient and water-saving features including Energy Star appliances (such as washers that use up to 40% less water ), drip-irrigation landscaping (that requires little to no irrigation) and garages prewired to charge electric vehicles.

Driving on 100% Sunshine

By Roy L Hales

Screen-shot-2014-03-18-at-3.43.47-PM1Peder Norby’s interest in renewable energy goes back to his wind powered home in Denmark. Even then, Peder knew that someday he would drive an electric vehicle. In 2005, he and Julie built a 4,600 square house, overlooking the Agua Hedionda Lagoon in Carlsbad. Peder wanted a cheaper form of transportation, powered by sunshine. Julie was more concerned that it be dependable, comfortable and fun to drive. They installed 21 solar panels on the roof and a year later bought their first EV. Like most first time EV owners, they assumed it would be necessary to hang on to their “gas car.” That proved to be true until 2009, when Peder bought a BMW Mini E. As a County of San Diego Planning Commissioner, he drives all over the county, but found the Mini E was taking care of all his needs. His gas car just sat in the garage. So he sold it.
