What is the scope of the energy indicator?

The scope of the indicator is to consider which part of the total energy required by the building/group of buildings (or by a specific function, such as heating or artificial lighting) and/or the generation from RES, during a certain period, is stored-in and then released from the storage system.

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.

Can thermal energy storage be used for building load management?

Thermal energy storage for building load management: Application to electrically heated floor Predictive control strategies based on weather forecast in buildings with energy storage system: A review of the state-of-the art

How to calculate storage material energy storage capacity?

The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].

What is energy storage?

Energy storage is an interesting proposal to relieve some of the pressure of future power grids towards decarbonization of the energy system, allowing integration between the RES and the power grid’s new ‘Smart’ configuration. The energy storage deployment, in 2018, reached nearly double of 2017 investment (Munuera and Pavarini 2020 ).

What is an energy storage system (ESS)?

In general, the most common applications of ESSs for power uses in buildings are “energy-intensive”, that means they are typically suited to store/release energy during time periods that range from minutes (short-term) to months (seasonal) and are not designed to manage power peaks ( Chatzivasileiadi, Ampatzi, & Knight, 2013).
