Closed Loop Energy Modeling

360 Analytics is committed to developing methods, tools and software designed to streamline measurement and modeling process and minimize costs with the goal of making Closed Loop Energy Modeling integral to the design and operation of buildings.  The basic steps are:

  • Design:
    Generate design phase, whole building energy models (proposed and baseline) for initial prediction of energy efficiency impacts. In the absence of knowing exactly how the building will be used, it is essential at this stage to use the best possible assumptions of building operations. At this step, Closed Loop Energy Modeling utilizes innovative techniques to allow measured usage and environmental data to be seamlessly integrated in the subsequent Calibration step.
  • Monitor:
    Perform monitoring of inherently unpredictable variables which drive building energy use (building occupancy, plug loads, weather, etc.). We work closely with the design team to identify the most important driving variables and develop a cost-effective monitoring plan.
  • Calibrate:
    Use the monitored data to adjust proposed building energy model assumptions made during the Design Assistance phase. This step of Closed Loop Energy Modeling relies heavily on not only updating the models with measured data, but also clearly documenting any changes to the initial energy model assumptions. Finally, calibration is evaluated over various time periods and conditions to better understand how well the model actually predicts building performance.
  • Verify:
    After calibration of the proposed model, update the baseline energy model with the same improved information on building usage and environmental conditions. Only now does the performance difference between the proposed and baseline energy models represent the true impacts of energy efficient design and technologies.
