3. SOLAR RESIDENTIAL LIGHTING
enLIGHTenment Magazine previously covered the growth in solar lighting in its January issue. Solar lighting has the advantage of long-term opera- tion during an extended power outage. These products now have run times of 6 to 12 hours.
It would be easy to combine the progress in solar lighting with the new portable lantern trend to create a new class of solar lights that charge outside during the day and provide resilient indoor lighting a er dark, day a er day, during extended power outages.
California has set an ambitious requirement that 100 percent of all new homes will be Net Zero Energy (ZNE) starting in 2020. This means that the homes must produce at least as much energy on-site as they use (this is typically accomplished by installing solar panels). The U.S. Department of Energy (DOE) also has a program to promote ZNE homes. While resilience isn’t a primary driver of the ZNE movement, homes that can generate signi cant energy can also become resilient if they invert and ba ery store the solar energy produced on-site.
Electric vehicles are gaining in popularity, led by the Tesla Model 3 Sedan. Nissan, Jaguar, Audi, Hyundai, Kia, BMW, Chevrolet, Mercedes, Porsche, and Volvo all plan to compete with Tesla for this growing market. Many
in the EV world have envisioned cars providing ba ery back-up power to homes when needed.
Tesla has gone further and o ered its car ba ery technology as a separate product for home power storage, known as the “Power Wall.” EVs and Power Wall type products can provide another path to resilient homes.
The Executive Summary for the New Residential Net Zero EnergyAction Plan for 2015-2020 is available.

These trends mean that there are a number of paths by which resilient lighting could become ad- opted into mainstream use over the next decade. Code adoption of resilient lighting in disaster prone areas could radically transform the residen- tial lighting industry. The types of disasters vary across the country, with
< Hurricanes and utility brown-outs impacting the East Coast and Gulf states;
< Tornadoes and oods in the heartland, and
< Earthquakes, tsunamis, wild res, and
mudslides threatening the West Coast Climate change is increasing the severity of most of these disaster types (except earthquakes
and tsunamis).
Nick Ferzacca, co-chair of the IES Resilience
Commi ee, indicates other possible directions that resilient lighting could go. “Run time and light levels are two critical issues for the commi ee. Also, should wiring be routed overhead – rather than in slabs – to prevent conduit lling with ood water? Distributed intelligence in lighting controls could provide information collection and communication to the lighting system a er an emergency.” He adds, “I do believe there will eventually be resilient lighting standards adopted into codes.” 
