What percentage of energy consumption must energy sub-meters monitor at a minimum?

The requirement to monitor a minimum of 90% of energy consumption through energy sub-meters is essential for achieving effective energy management and optimization in buildings. This high monitoring percentage ensures that most of the facility's energy use is tracked, allowing for detailed analysis and identification of areas where energy efficiency can be improved.

By focusing on such a significant proportion of energy usage, building operators can collect reliable data that informs strategic decisions on energy consumption reduction measures. This level of monitoring is also critical for compliance with sustainability standards within the Estidama Pearl Building Rating System, promoting ongoing performance evaluation and adjustments as necessary.

Choosing a lower percentage, such as 50% or 75%, would not provide the same depth of insight into energy usage, potentially overlooking critical areas that contribute to higher consumption, and therefore hinder the overall effectiveness of building energy management strategies.
