PLANNED ACTIVITIES

This time, the renomap consists in one unique step due to the characteristics of the renovation. The morphology and the architectural qualities of the building make complicated to increase the energy performance without modifying its own design. As a general rule, the integration of PV panels on roofs is essential to transform buildings into self-sufficient and resilient urban actor. One of the main renovation measures is to install enough PVs to guarantee the renewable energy supply.
To consolidate the envelope as an element that guarantees airtightness, high thermal comfort level and enough light to develop certain activities is a must. That is why new external solar protections, shades and adjustable blinds, have been proposed. The internal cavity of the façade wall is filled with insulation material and the windows are replaced with high performance low emissive glazing and frames.
In the interior the HVAC system is updated with new heat pumps and and domotic controls allowing to customize the humidity and temperature levels on each precinct. The lighting systems is redesigned and LED luminaires are installed. The partitions are upgraded with thermal and acoustic insulation materials.
