Presentation of the IEA-EBC Annex 86 and ST4-smart ventilation subtask

IEA-EBC Annex 86 “Energy Efficient IAQ Management in residential buildings” aims to propose an integrated rating method for the performance assessment and optimization of energy efficient strategies of managing the indoor air quality (IAQ) in new and existing residential buildings. Our goal is to work in an international collaboration so that the different approaches to design and operation of ventilation in different countries are accounted for. The work includes collection and systemisation of existing knowledge and data regarding pollution sources in residencies, turning performance based evaluation methods into practice as well as exploring the opportunities brought by IoT connected sensors. Rather than conducting new laboratory research and tests, we want to study current use cases representing innovative IAQ management strategies and based on them, develop road maps to ensure the continuous performance of the proposed solutions over their lifetime.  
The project gathers experts from different fields including mechanical engineering, building science, chemistry, data science and environmental health, who will work together with other stakeholders. We divide our work into six subtasks. One of them, subtask 4, has a direct focus on ensuring performance of smart ventilation. This means a focus on practical conditions that assure reliable, cost effective and robust implementation of smart ventilation.
