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

According 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.
