The renovation measures proposed by ALDREN focus on improving the Energy Efficiency of Les Dunes. They consist in renewing the HVAC system, the Domestic Hot water supply service leaving fossil fuel behind and using a more ecologic technology. To install a Smart lighting system and including Renewable energy generation through Photovoltaic Panels, updating the most part of the building systems.
On the meantime, all the new services will be monitored by a centralized control system allowing the property owners and managers to understand how Les Dunes works, where it is possible to optimize its use and to check its current status. All these active measures are wrapped inside a high-spec envelope composed by low emissive glazing systems and a new insulated facade and roofing, neutralizing the thermal bridging on the most critical locations.
All these energy Renovation Actions will have an important impact on Les Dunes Internal Environment Quality, that was monitored during the study, to understand how the internal comfort is affected by the current building conditions.
Other important renovation measures don´t have to be with the building itself but with the appliances installed on it. For hotels, the kitchen is the space with more energy consumption per m2 what makes the use of high efficiency appliances essential.
The Energy Renovation Actions are listed inside Les Dunes Renovation Roadmap distributed in packages to maximize the energy savings and investment sustainability during specific periods of time.
ESTIMATED FINAL ENERGY SAVINGS
Total final energy: 73.5%
