Can energy flexibility KPIs be computed directly from building performance data?

A small group of data-driven energy flexibility KPIs can be computed directly from building performance data without the need for baseline demand profiles. However, the majority of energy flexibility KPIs rely on the comparison between the building performance profiles under the baseline and flexible operation scenarios.

How are KPIs selected for energy performance?

The selection of KPIs is made for energy performance. In (Del Pero et al. 2018), the focus is given to energy storage in buildings, testing KPIs in several case-studies. Adding PV to the storage, the work in (Kourkoumpas et al. 2018) performs the life cycle analysis regarding stakeholders’ needs.

What are KPIs in thermal energy storage?

Similarly, Hanak et al. (Hanak et al. 2015) defined KPIs to estimate reliability indices based on the uncertainty of the input to a process model of a coal-fired power plant. A first attempt to collect organized KPIs used in thermal energy storage (TES) can be found in (Cabeza et al. 2015).

What are the main KPIs for the assessment of ESSs in buildings?

The main KPIs to allow the assessment of ESSs in buildings are presented and descried below. 1. Storage capacity This is the quantity of stored energy in the storage system or available immediately after it is completely charged.

How complex are KPIs?

The complexity of the KPIs was qualitatively assessed based on the required amount of data processing and computation. Performance aspects: Depending on the use cases, KPIs may have different primary performance aspects. The latter are categorized into energy demand, power demand, cost, greenhouse gas (GHG) emissions, impacts on IEQ, and comfort.

What are the KPIs of a battery system?

For battery systems, Efficiency and Demonstrated Capacity are the KPIs that can be determined from the meter data. Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out).
