NZEB Renovation 13 ZEMedS Goals: Requeriment 1: C PE Prod RES 0 Primary energy consumption yearly (heating, cooling, ventillation, DHW and lighting) is produced by local renewable energies. Requeriment 2: C FE 25 kwh/m2 y FE consumption yearly (heating, cooling, ventillation and lighting) per conditioned area Requeriment 3: Indoor air quality guaranteed (CO 2 1000 ppm) and temperature above 28ºC 40 hours yearly during occupancy National factors for conversion in energy and CO 2 have been taken into account (data 2014). Primary Energy from non renewable energy sources covered by renewable energy Final energy Indoor Environmental consumption (all uses Overheating limited to Quality (IEQ) is except DHW & cooking) guaranteed 0 kwh/m².year (annual balance) C FE 25 kwh/m².year 40 hours over 28ºC annually CO 2 1000 ppm

Recommended Measures 19 Measure Why is recommended and what Windows Replacement to be completed Photovolatic System Very poor performance windows are still present, they need to be replaced with ihlow e ones. Further Electric Energy Production Building Management System Lighting Replacement and Management System For reducing energy waste and optimizing usage efficinecy Very poor lighting system is deployed. Luminaires need to be replaced and a management system integrated.
Specific Features and Remarks 20 Specific Remarks The school has a lot of evening courses, thus it is opened till night. There are a lot of glazed facades. Windows Replacement was started in 2015 with 4 facades. It needs to be completed. Seismic Compliance needs to be assessed. After the assessment works could be needed.
