Low embodied carbon ventilation systems for healthy learning spaces: comparative analysis of systems to provide fresh air in temperate climates
While carbon neutrality is targeted for 2050, the building sector is responsible for significant GHG emissions but has a mitigation potential of 66% according to the IPCC. Public projects are given particular attention. However, MEP systems still account for 13% of the embodied carbon emissions in schools, and little effort is shown to reduce them. While passive cooling is well studied, much less is known about passive strategies to supply fresh air. This research provides a comparative analysis of passive, hybrid and active systems designed to provide fresh air to classrooms in temperate climates. Five case studies with heat recovery and CO2 sensors are investigated through interviews and site visits. The paper outlines recommendations to prioritise passive strategies whilst maintaining adequate levels of IAQ. A life-cycle embodied carbon assessment of three system types found that the selected hybrid system leads to a reduction in the carbon emissions associated with HVAC.

Abstract
While carbon neutrality is targeted for 2050, the building sector is responsible for significant GHG emissions but has a mitigation potential of 66% according to the IPCC. Public projects are given particular attention. However, MEP systems still account for 13% of the embodied carbon emissions in schools, and little effort is shown to reduce them. While passive cooling is well studied, much less is known about passive strategies to supply fresh air. This research provides a comparative analysis of passive, hybrid and active systems designed to provide fresh air to classrooms in temperate climates. Five case studies with heat recovery and CO2 sensors are investigated through interviews and site visits. The paper outlines recommendations to prioritise passive strategies whilst maintaining adequate levels of IAQ. A life-cycle embodied carbon assessment of three system types found that the selected hybrid system leads to a reduction in the carbon emissions associated with HVAC.
