Energy-intensive building

The Energy'Lab is a 100 m² building, located in the heart of the EPF Montpellier campus. This autonomous and disconnected building will have to meet its energy needs (electricity, heat, cooling or air conditioning, lighting, control, metrology, etc.). This building is also intended to be upgradeable. The technical solutions to meet its needs will be modified over time, the objective being to integrate cutting-edge technical solutions and to allow Energy'Lab to integrate the innovations present on the market.

Owner approach of sustainability

The building developed is a positive energy building that will be used as a research and development platform around energy management and control. This building is also made from sustainable materials. The companies selected for the realization as well as the one supplying energy systems are local (at least in the Occitanie region).

Architectural description

The building consists of a wooden frame the attached file contains descriptive elements relating to the composition of the walls and in particular the insulation. Work has been carried out to limit thermal bridges.

If you had to do it again?

Change of some providers. This decision would result in an increase in costs and a faster completion of the site. Many hazards were present during this work given the pandemic context that was not anticipated at the start of work in February 2020. Improvements in communication were necessary to achieve this.

Building users opinion

Building not yet occupied.

Energy consumption

  • 34,00 kWhep/
  • 37,00 kWhep/
  • RT 2012

  • 34,00 kWhef/
  • The energy consumption is as follows: - heating: 14 kWh / m² / year - air conditioning: 10 kWh / m² / year There is no DHW in the building

Envelope performance

  • 0,24 W.m-2.K-1
  • wood frame

    Home automation systems are at the heart of the Energy'lab in order to improve the operation of the installation, particularly from the point of view of energy performance.
