The building has an area of 528m2 and has been completely renovated. CO2 emissions in the construction phase were calculated through the ecômetro LCA® tool and a minimisation strategy was contemplated. The final carbon footprint has been 196 tonnes of CO2 (364 KgCO2eq/m2) that were compensated through the Community Reforestation "CommuniTree" initiative. The building has been designed with high energy efficiency and PassiveHaus standards. All heating and cooling consumptions are electrified and demand is covered by 100% renewable energy.
