The Energy Performance Guarantee (EPG): development of a methodology guaranteeing the energy performance of rehabilitated tertiary and collective buildings.

An Energy Performance Guarantee (EPG) offers owners the reassurance that energy consumption after rehabilitation will not exceed the expected level.

This energy consumption will be verified by actual figures, not just by theoretical data.  In the event that the guaranteed level of energy performance is not reached, the causes will be identified, the flaws will be repaired and the customer will receive compensation on the basis of the difference between the actual and the guaranteed consumption level. 

In 2012, ADEME issued a second Call for Expressions of Interest, in the frame of the Investissements d'Avenir (Investments for the Future) programme. This CEI, which focuses on high-performance buildings and communities, provides for the introduction of Energy Performance Guarantees for ambitious energy renovations of tertiary apartment buildings.

ADEME's Rhône-Alpes regional delegation has launched a Call for Expressions of Interest (CEI) focusing on Energy Performance Contracts. The idea is to select several development projects in 2012 and provide the main contractors with project management assistance and with help in defining a measurement and verification plan. The support programme targets the private tertiary sector and the private or public hospital sector.

The EPG can also be used to secure a bank loan in the event that the main contractor plans to take out a loan to pay for the work.
The EPG must be based on a reliable methodology, the development of which requires a coordinated research effort. This is the purpose of the EPG workshop set up by the Fondation Bâtiment-Énergie.

Its research focuses on collective residential buildings and tertiary buildings undergoing extensive renovations involving several building trades.

The methodology must be designed to achieve the following objectives:

  • attain Factor 4 levels of greenhouse gas and energy consumption reduction, or work towards Factor 4 levels (i.e. achieve at least Factor 2 levels without destroying the potential to reach Factor 4);
  • promote the development of the EPG for the whole renovation project, covering the façade, systems and regulation management;
  • find the right trade-off between the cost and the error rate of the method used to measure and verify actual performance;
  • explain and correct the differences between predicted and actual measurements.

This methodology is being developed in a collaborative manner, within a workshop led by a works coordinator and composed of two groups:

  • a principal research group that is conducting the research and studies necessary to establish the measurement and verification plan;
  • a group of users to guide, evaluate and refocus the research group's work in line with the challenges, constraints and expectations associated with the EPG.

The EPG methodology will be designed for use by a main contractor and a service provider. This service provider may be an organisation working on the technical side of the building trade (such as operations, industry, construction and installation, energy production, project management, engineering and design), in the financial or insurance sector, or in a new business focusing on the integration of building renovations and EPG measures.
