IAQ Improvement by Smart Ventilation Combined with Geothermal Renewable Energy at nZEB

The building sector has the responsibility of being a generator high carbon emissions, due to inefficient energy consumption in last decades. For European Union (EU) and sector, this pollution generated great impact concern, establishing objectives sustainability efficiency short term. EU, committed sustainability, established several guidelines, aiming at reducing emissions. reason, directives have been published increase buildings, with EPBD 2018/844/EU most up-to-date regulation. This directive mainly focuses on emissions increasing systems but it also refers importance indoor air quality indices smart management ventilation systems. Before was published, many implemented strategies did not consider (IAQ) their scope comfort parameters. Therefore, study analyses performance system, controlled smartly cover demand IAQ rates via CO2 ppm, through renewable geothermal carried out LUCIA building, near Zero Energy Building (nZEB), which belongs University Valladolid, Spain. stands for one sustainable buildings world, according LEED certification, ranking as northern hemisphere. is equipped cutting-edge systems, zero Several parameters analysed (air speed, enthalpy, flow, temperature, humidity, kWh, climate data, etc.) enabling an optimisation combined All monitoring data obtained by analysed, providing favourable outcomes, establishment levels, 2018/844/EU. After study, removable can be exported strategy reach levels
