Building Dynamics for University Campuses

Building Dynamics offers a diverse set of features for helping campuses to conserve energy and meet their sustainability goals. Building Dynamics combines electric load disaggregation with sensor-driven occupant behavior analytics to exploit the dynamic changes in buildings for savings. The key features of the resulting service include:

Portfolio Level Analysis

Portfolio level analysis tracks consumption across campus and provides mechanisms for searching for saving opportunities. Buildings are compared and benchmarked against each other using a diverse set of metrics and proprietary interval data analysis. These provide an assessment of the energy savings potential of each building enabling the prioritization of opportunities.

In the cases where a campus is master-metered, the sensing and metering infrastructure supported by Building Dynamics can be used to sub-meter buildings individually to track commodity consumption (electricity, gas, steam and chilled water) at the building level.

The portfolio level features together with building level analytics and the measurement and sensing capabilities allows zooming from the portfolio level down to specific breakers within a building using a single platform. This helps campuses track and achieve their sustainability goals in a cost-effective manner.

Occupant Behavior Analytics

Campus buildings are typically very dynamic environments with continuously changing schedules and occupancy patterns. These forces buildings to over-provision to sustain occupant comfort inevitably resulting in redundant energy usage.

Building Dynamics is specifically designed to make campus buildings more efficient by exploiting real-time information about building usage. The behavior analytics engine inside Building Dynamics extracts multi-level models of occupancy and correlates them with the consumption patterns of end-use loads to identify energy saving opportunities. These are communicated using alerts and monthly reports and can also be directly integrated into the existing building management systems. This empowers the building management system to make continuous adjustments to their setting to conserve energy.

Online Measurement and Verification of Savings

The performance of each building and the campus as a whole is tracked via a measurement and verification (M&V) module inside Building Dynamics. The M&V module compares the consumption of the building to its previously computed baseline to accurately report the savings achieved. Combined with the sub-metering and sensing functionality the M&V process can also be configured to track the performance of individual measures.

The M&V module normalizes for weather, occupancy and other changes in the building to accurately capture the achieved savings.
