Role of ESCOs in Nearly Zero Energy Building Renovation: NeZeR project

Share this Post:

The NeZeR project promotes the implementation and smart integration of Nearly Zero Energy Building Renovation (NZEBR) measures and the deployment of Renewable Energy Sources (RES) in the European renovation market. NeZeR also aims to secure the impact of the project activities and results during and beyond its duration. This will be facilitated by creating national clusters consisting of the most relevant stakeholders that can secure the long term implementation of Nearly Zero Energy Building Renovation (NZEBR) and utilization of Renewable Energy Sources (RES).

An Energy Service Company (ESCO) is defined, according to Directive 2010/31/EU, as a natural or legal person that delivers energy services and/or other energy efficiency improvement measures in a user's facility or premises, and accepts some degree of financial risk in so doing. The payment for the services delivered is based (either wholly or in part) on the achievement of energy efficiency improvements and on the reunion of the other agreed performance criteria.

In ESCO projects, it is common to contain the same elements, for example; site survey and preliminary evaluation, guarantee of the results by proper contract clauses, project financing, operation and maintenance, and other similiar concepts. There are a number of different ESCO contracts in which the most prevalent is the Energy Performance Contracting (EPC). Other types of contracts are Energy Supply Contracting, Chauffage (heating), Comfort contracting, among others. The popularity of these contract types differ between countries.

The role of ESCOs in NZEBR and the ESCO market situation in Finland, Sweden, the Netherlands, Romania and Spain have both been studied and compiled briefly in this report.
