SunDay is a global day of action on September 21st, 2025, celebrating the unstoppable rise of clean energy. We’ll come together to showcase the power of the sun and wind, the energy sources that can power our world without pollution.

Come tour a net zero PHIUS certified home that was recently built in downtown Vienna. Learn how energy efficiency contributes to better indoor air quality, lowers utility bills and makes your home quieter and more comfortable. Volunteer Electric Coaches from GoElectricDMV.org on hand to consult on your home electrification journey!
