All systems must be commissioned by qualified professionals who can verify proper integration and performance according to design specifications. This includes testing of control sequences, calibration of sensors, and verification of energy performance metrics.
Major Certification Programs and Solar Requirements
LEED Certification
LEED (Leadership in Energy and Environmental Design) certification offers a comprehensive framework for sustainable building practices, with solar energy playing a crucial role in achieving certification points. The system operates on a 110-point scale across multiple categories, with energy efficiency and renewable energy contributing up to 33 points.
Buildings can earn points through various solar implementations. Installing solar photovoltaic systems can contribute up to 7 points, depending on the percentage of total building energy offset. Solar thermal systems for water heating can earn additional points under the energy optimization category, particularly when they reduce conventional energy use by 20% or more.
The LEED v4.1 framework specifically rewards solar installations through both on-site and off-site renewable energy credits. On-site solar installations receive higher point values, with buildings earning one point for every 2% of total energy costs offset by renewable sources. Projects can also earn points through solar-ready design features, even if immediate installation isn’t planned.
Notable examples include the Bullitt Center in Seattle, which achieved LEED Platinum certification partly through its rooftop solar array that generates 60% more energy than the building consumes annually. The Bank of America Tower in New York similarly earned LEED Platinum status by incorporating building-integrated photovoltaics alongside other sustainable features.
To maximize LEED points through solar implementation, projects should integrate solar planning early in the design phase and consider both direct energy generation and indirect benefits such as reduced heat island effect and improved daylighting strategies.
BREEAM and Other Programs
While LEED certification is widely recognized in North America, several other prominent green building certification programs emphasize solar energy integration and sustainable practices.
