What are the parameters?

The calculations made by TEXTINERGIE are based on a number of model parameters. These most significantly include the following elements:

• - The model building: it assumes an office space situated in the middle of the façade. There are two possible selections for the glazed surface of the room (40% and 80% of the office façade).
  
  
• 
• Model building
  
  
• - Locations used: they are representative of different climatic zones. For towns located in France, they correspond to the climatic zones according to RT2005,
• - Aspects: TEXTINERGIE considers different aspects depending on the hemisphere the selected town belongs and does not take into account the less exposed façade aspect. Therefore, South, Est, West and North-West aspects are possible for towns located in the northern hemisphere. North, Est, West and South-West aspects are possible for towns located in the southern hemisphere,
• - Glazing: it assumes reference double glazing as defined in the standard EN 14501,
• - Textiles: the thermal and optical properties of the selected textiles as well as their positioning (internal or external),
• - Hours of occupancy (from 7 am to 7 pm) : the duration of occupancy determines how some of the parameters work,
• - Control of the ambient temperature: heating and air-conditioning maintain the temperature at specific reference values,
• - Control of the ambient luminosity: the position of the solar protection device is adjusted according to the amount of incoming natural light.
