OXIVI, thermal engineering office specialized in indoor air quality

Founded by Sélia Bouyehia, OXIVI is a thermal and indoor air quality (IAQ) engineering office specializing in energy efficiency in buildings and improving indoor air quality. Composed of thermal engineers, the OXIVI team supports its customers from the design of construction & renovation projects.

Reduce the environmental impact of your new & existing buildings

OXIVI offers advice and technical & energy studies during the construction or renovation of your building.

Our thermal engineers accompany you beyond the regulatory thermal and energy studies of the RT 2012 to help you save energy and choose the most efficient systems (heating, ventilation, air conditioning…) & durable materials adapted to your project.

Our software is recognized as favourable by the CSTB for the method of regulatory calculations in RT2012.

Environmental quality: healthy & ecological design

Building and renovating without taking into account the health and environmental impact, at OXIVI, it doesn’t make sense. To guarantee you better air quality in your building, we assist you in the choice of renewable energy, ventilation design and the choice of your materials (bio-sourced or not).

OXIVI uses the first indoor air quality simulation software.
