Acronym of the case

Dynacité Pilot site implementation

Lessons learnt

The implementation of the pilot project is on-going, so the impact of implementation of alternatives in terms of real energy savings will be difficult to evaluate. We are sure to reduce costs corresponding to energy supply and maintenance because the chosen consortium has engaged on a 42,5% reduction of consumption, compared to the initial situation. Within the implementation of the pilot project, Dynacité has identified some possible solutions to improve the design-construction-maintenance contract. Indeed, because we are involving all stakeholders at the early stage, it is important to know our needs, and clearly define the program of requirements, diagnostics and objectives of the project. This implies more time and resources internally, but this may be reduced in the replication, due to experience.
