This probably work by admitting air (as a window would) and denying solar radiation (as a window would not). Other factors to consider include the optics associated with light passing through the bottle and how focused air might affect people's perception of temperature (wind chill). The bottles might reflect enough light away from the structure to have a discernible effect.
