Performance Details

Net Zero Operational Carbon

Buildings or developments that are verified and certified as “net zero operational energy and/or carbon.” The building should demonstrate the highest levels of energy efficiency with the use of either renewables generated onsite or renewable energy procured offsite.

Achieved Certification Scheme: Passivhaus Platinum
Achieved Certification Level: The building was designed with Passivhaus criteria supported by a PHPP(Passive House Planning Package) calculation Other Achieved Certification Scheme and Level: Certificate of Energy Efficiency of the Finished Building: A Energy Use Intensity (EUI) (kWh/m2/yr): 1.65 Onsite Renewable Production Intensity (RPI) (kWh/m2/yr): 14.69 kWh/m2/yr from a 33.3 kW solar photovoltaic installation in the building roof Verification Year: 2021

Related to the use phase, the building was designed with Passivhaus criteria and it has a very high energy efficiency level.

Related to the rest of the construction phases, a complete LCA was developed with the tool ECÓMETRO ACV (UNE-EN 15804 and UNE-EN 15978 based tool). In this point, the decision of a building structure with CLT (cross laminated timber) with FSC certification, helped in the reduction of embodied carbon.

LCA results:
Global Warming: 1.30e+6 kg CO2 eq (Carbon Footprint)
Ozone layer depletion: 4.94e+2 kg CFC-11 eq
Photochemical Oxidants: 6.56e+2 kg C2H4 eq
Acidification: 9.24e+3 kg SO2 eq
Eutrophication: 1.86e+3 kg PO4-3 eq
Abiotic resources depletion: 1.25e+2 kg Sb eq
Total primary energy consumption: 1.57e+7 MJ eq
Besides, the building is 100% electrified (no combustion), uses only 100% renewable electricity, and the carbon footprint was compensated with ClimateTrade.

The building does not emit CO2 at all, archive net zero carbon, and has the CO2 NULO certification.
