Although those who reside outside of San Francisco may not be aware of the fact, mid-April 2016 marked a huge milestone in the advancement of green technology in the city and its mandated usage in all newly-constructed buildings.The new legislation, unanimously approved by the San Francisco Board of Supervisors on April 19, states that all new buildings with 10 stories or fewer, including all residential and commercial projects, must include a photovoltaic solar panel installation that encompasses 15 percent of the building’s total rooftop. Moreover, the area that is dedicated to the installation must be positioned in full sunlight and free of any shade or obstructions.
