scope:

The present document specifies the requirements for a Global KPI for energy management (KPI_EM) and its underpinning Objective KPIs addressing the following objectives for the ICT sites of broadband deployment:

• energy consumption;

• task effectiveness;

• energy reuse;

• renewable energy.

The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.12].

Energy management of ICT sites comprises a number of independent layers. The present document addresses performance of infrastructures that supports the normal function of hosted ICT equipment (e.g. power distribution, environmental control, security and safety). The present document does not address other layers such as performance of ICT equipment itself, performance of usage of available processing power, and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers (e.g. energy consumption per itemized outcome).

The environmental impact and management of different energy sources are outside the scope of the present document.

Within the present document:

• clause 4 describes the energy parameters for ICT sites together with inclusions/exclusions of different energy contributions;

• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPI_EM.
