Services
Energy Audit
Our ASHRAE-compliant energy audits identify efficiency opportunities through detailed facility analysis. We conduct walk-through assessments, engineering analyses, and investment-grade evaluations to quantify savings potential. With expertise in federal and state protocols, our audits provide actionable roadmaps for energy conservation measures across commercial, industrial, and institutional facilities.
Building Commissioning
As a Certified Building Commissioning Firm, we offer full-spectrum services including new construction, retro-commissioning, and monitoring-based ongoing commissioning. Our CBCP-certified engineers ensure optimal performance of HVAC, BAS, and central plant systems through data-driven processes that enhance efficiency, reliability, and occupant comfort across building lifecycles.
Energy Modeling
We employ advanced building energy modeling (BEM) and hydraulic simulation tools to optimize system performance. Our engineers create digital twins of facilities to test efficiency scenarios, validate design assumptions, and predict energy consumption patterns. This enables data-informed decisions for new construction, retrofits, and operational improvements in complex campus environments.
Performance Verification
Our third-party Measurement & Verification services use IPMVP protocols to quantify energy savings from efficiency projects. With CMVP-certified professionals and engineering PhDs, we implement rigorous data collection and analysis frameworks to validate performance claims. This ensures transparency and accountability for clients pursuing ESPC, UESC, or PACE financing models.
Remote Monitoring
Our VisionBee platform enables 24/7 remote energy management through automated fault detection and diagnostics. Real-time monitoring identifies system inefficiencies, prioritizes maintenance needs, and prevents equipment damage. This proactive approach reduces operational costs while maintaining optimal performance across geographically dispersed facilities and central utility plants.
