This paper focuses on ventilation solutions of a net zero energy building. We present the monitoring results after two years as part of the PHD programme research “Design, simulation and control of hybrid ventilation systems in high energy performances buildings” founded by Elithis Groupe in parternship with the LEPTIAB of La Rochelle.
The objective of this paper is to study the ventilation solution of a net zero energy building, the thermal comfort and the indoor air quality in terms of CO2 [1]. We present in the first part, a building description and ventilation principle, in second part we present the energy monitoring results of the Elithis Tower and ventilation consumption system during 2009 and 2010. Finally we show the ventilation performances in terms of energy, CO2 concentrations and thermal comfort.
Results show an office building with an acceptable thermal comfort with a high energy performance but with a relatively low indoor air quality.
