Realizing the economic and environmental benefits of energy-efficient building designs requires attentive and well-informed operation. Providing real-time feedback to occupants and operators about actual energy use is a powerful tool in pursuit of this goal. However, without context, this feedback can be unhelpful or even misleading. Control limits contextualize feedback by establishing reasonable ranges for the reported data that are tailored to a building’s unique characteristics. This presentation is an introduction to two related methods of establishing control limits for building energy consumption using a combination of predictive modeling, historical data analysis, and energy-conservative logic.
