By integrating solar technology into façades and rainscreens from the earliest project stages, architects can reduce redundancy, align energy goals with design intent, and rethink how envelopes are composed. Since ancient times, solar energy has been used to measure time, support planting and harvesting, and provide protection from heat and cold. At ENVELON, we transform long-term building science expertise into professional BIPV construction projects and solar architecture. Explore. This study outlines recent photovoltaic developments and notable architectural features conducive to enhanced photo-voltaic integration into buildings. Photovoltaics, with. Photovoltaics, more commonly known as solar panels, are one of the purest and most reliable methods for producing renewable energy.
