We implemented a turnkey energy conservation solution. We conducted an ASHRAE Level II Energy Audit, including load profiling and benchmarking, to pinpoint inefficiencies in the packaged HVAC units. Then designed a fully integrated Building Automation System (BAS) to manage all site-specific mechanical system. Performed a swift retrofit, installing IoT-based smart thermostats and centralized control panels. Installed new, high-efficiency packaged HVAC systems at the highest priority locations. At the end Implemented real-time energy dashboards and Io T sensors for continuous tracking of energy usage and system faults. This solution not only achieved compliance and green building goals but also provided the client with the ability to access rebates and incentives through improved energy performance.
