This report focuses on the provision of enhanced Indoor Air Quality (IAQ) Models that are able to evaluate indoor hygienic and health/well-being conditions through identifying contamination of the air with various compounds, such as carbon dioxide (CO2), carbon monoxide (CO), and volatile organic compounds (VOCs). This was accomplished through the development of an improved IAQ model to be integrated in the Energy Management System (EMS) program.
This document starts with a brief introduction and definition of the IAQ, a literature review and importance of the IAQ for human health, followed by the characterization of the main pollutant sources which are key factors to improve in the IAQ model developed. Then, the modelling methodology adopted is introduced and the IAQ model inputs are detailed and finally the numerical solution, which is adapted for direct integration in E+ language, is presented. The main outcome of this document is a proposal of an improved mathematical model for the indoor air pollutant concentration prediction adapted for the calculation engine of the Building Energy Performance Simulation (BEPS) - E+.
