Thanks to these Princeton commercial properties for also taking an important step in reducing their energy consumption and saving money on energy costs. Each property initiated or completed an energy audit of their property using the NJ Office of Clean Energy's Direct Install program. Property owners that installed the recommended energy efficiency upgrades saved 70% of the installation costs.
