  Sunsprint Engineering implemented a 102 kW AC PV system with a 3D BIM-integrated monitoring platform, enhancing energy efficiency and operational transparency.

Located at 1002 Washington Avenue, the Houston Permitting Center is a four-story building covering 185,214 sq ft. Primarily utilized for office space and meeting rooms, this structure also features a fully finished basement. In a collaborative effort, the City of Houston, TAMU ESL, and Sunsprint Engineering enhanced the building's user experience, improved its energy efficiency, and reduced electricity costs.

A type 2A warehouse, the building was converted to a type 2B in 2011. Additionally, new, cost-effective LED lighting was also installed throughout the facility. The upgrade resulted in a significant reduction in utility costs by 159,237 kWh annually and decreased the building's energy consumption by two-thirds, saving $17,516 in maintenance costs each year. A metal canopy structure was installed on the roof, supporting a 102 kW AC (113 kW DC) photovoltaic (PV) system. Sunsprint also provided a user interface kiosk in the building, allowing the public to access and monitor the system. This monitoring setup features a 3D BIM model integrated with Microsoft Power BI for real-time data visualization.
